No leakage, pH value of 6.5 to 8.5 is appropriate.

(17) Step S2: Field Layout

(18) Dig a ring-shaped ditch 3 along the inner side of ridge 2 around paddy field 1, 20.5 to 1 meter away from the ridge, with a width of 0.8 to 1 meter and a depth of 0.3 to 0.5 meters; for larger areas (generally more than 3 Chinese acres), dig a cross or # shaped field ditch 4 in the field. The field ditches 4 are 0.3-0.5 meters wide and 0.3-0.5 meters deep, and the sum of the ditch area accounts for no more than 8% of the paddy field area, and the ditch-ditch can be connected. Heighten and widen the ridge 2, tamped and strengthened. The height of the ridge 2 is 50-60 cm, the bottom width is 60-70 cm, and the top width is 50-60 cm. An inlet channel 5 is built on the ridge on the side of the rice field 1 and connected to the water inlet pipe 6 to the rice field; the drainage pipe 9 is built at the bottom of the ring-shaped ditch 3 on the other side of the rice field 1. The inlet pipe 6 and the drainage pipe 9 are respectively provided with an inlet control assembly 7 and a drainage control assembly 10, and are installed at the outlet and the outlet of the inlet pipe 6. A plurality of grid nets 11 (specifically shown in FIG. 1) are provided at the drain outlet of the drainage pipe 9 and the net diameters of the grid nets 11 are sequentially reduced.

(19) Step S3: Soil Preparation and Fertilization

(20) Paddy field 1 should be applied with sufficient base fertilizer, and the amount of fertilizer should be controlled at 1000-2000 kg/Chinese acre according to the fertility of the land. After evenly spreading into the field, irrigate and prepare the land.

(21) Step S4: Stocking of Tylorrhynchus;

(22) From February to April or from July to August every year, after the rice field is leveled and the base fertilizer is applied, release Tylorrhynchus 7 to 15 days before transplanting; The larvae are sown in dry fields, and the mud is evenly sown in the rice fields, and the stocking density is 250-300/m.sup.2.

(23) Step S5: Management of Tylorrhynchus Proliferation;

(24) After the feed is crushed and fermented, fully mix with 10 times the dry rice stalk powder and feed evenly; once a week, a feeding amount is 3% of the weight of the Tylorrhynchus, reduce the feeding amount on cloudy days and low air pressure, not to feed when the water temperature is higher than 35? C. or lower than 15? C.; Intensify inspections, check the ridges for loopholes and water leakage, and remove wild fish, crabs, rice field eels and other pest predators.

(25) Step S6: Rice Planting

(26) Choose rice varieties with strong fertility tolerance, lodging resistance, disease resistance, moderate growth period, and good quality. Mechanical harrowing the field more than 2 times to make the mud floating and rotten, the field surface is fully leveled, and the height difference of the field surface is not more than 3 cm. Seedling transplanting can be mechanical transplanting or throwing seedlings, and the seedlings should be shallow, even, stable and straight. Planting about 100,000 basic seedlings per Chinese acre can appropriately increase the planting density on the inner side of the ridge and beside the ditch, and give full play to the marginal advantages.

(27) Step S7: Field Management

(28) Manage according to standard rice planting procedures. Fertilization is mainly based on basic fertilizer, supplemented by topdressing, mainly organic fertilizer, supplemented by chemical fertilizers, topdressing is little amount and multiple times, select good quality cold commercial organic fertilizers, and the use of urea and other chemical fertilizers harmful to Tylorrhynchus is strictly prohibited; prevention should be primary control of diseases, pests and weeds in paddy field, comprehensive prevention and control, and reduce the amount of pesticide application. High-efficiency, low-toxicity, and low-residue biological pesticides are the best choice for rice disease control. Organophosphorus and pyrethroid pesticides that are highly sensitive to Tylorrhynchus are prohibited. To ensure the safety of Tylorrhynchus, it is necessary to strictly control the safe use concentration of pesticides. Spray the pesticides on the rice leaves instead of spraying into the water. It is advisable to apply the pesticides separately. Add water to the rice field to 15-20 cm before spraying, and change the water in time after spraying.

(29) Step S8: Water Level Controlling

(30) The water level for rice transplanting is 2 to 3 cm; After transplanting seedlings, water shall be injected immediately to keep them green, and the water level shall be controlled at 4 6 cm. After the seedlings return to green, the water level of the paddy field shall be naturally dried to 3 cm to promote tillering; When the total number of stems and tillers reaches 80% of the expected number of panicles, stop watering and dry the field up naturally. According to the growth of seedlings and leaf color, dry the field until there is slight crack on the field surface. After drying the field, water 5 cm from booting period, keep water layer 10 ? 15 cm at heading and flowering period, dry and wet in the middle and late period of grain filling; Drain the accumulated water in the field 7 days before rice harvest and keep the field moist.

(31) Step S9: Rice Harvesting;

(32) Manual harvesting or mechanical harvesting, but note that the turning angle of the harvester should not be too large, so as not to affect the leveling of the field and the Tylorrhynchus in the field. Fill water in time after harvesting and keep the water level 5-10 cm.

(33) Step S10: Tylorrhynchus Capturing.

(34) When the Tylorrhynchuss are sexually mature, dry the rice field for 1 to 2 days, in the dark night, water 20 to 30 cm, after a large number of sexually mature Tylorrhynchuss float, open the drainage pipe and arrange a soft gauze net at the drain to catch the Tylorrhynchus, the captured Tylorrhynchus are placed in a container with holes, when the Tylorrhynchus are drilled out of the holes to separate them from the debris, then clean with clean water at 14? C.-18? C. for 2 to 3 times, and temporarily store at 13? C.-15? C.

(35) In the above step S3, organic fertilizers such as manure and cake fertilizer with long fertilizer efficiency are preferred for the base fertilizer.

(36) In the above step S4, the Tylorrhynchus larvae of 50 to 60 rigid nodes or more are selected Tylorrhynchus, and the larvae have no damage, no disease, and good vigor.

(37) In the above step S5, coarse feed such as soybean meal, corn flour, wheat bran, and bran may be selected as the feed.

(38) In the above step S6, the rice variety is Guang 8 You 165 or Guang 8 You 169 or Guang 8 You 2168 or Guang 8 You Jin Zhan or Wufeng You 615 or Meixiang Zhan 2.

(39) In the above step S8, the rice field where Tylorrhynchuss and rice grow in symbiosis should be lightly sun-dried to prevent the Tylorrhynchus from dehydration and death during the sun-dried field.

(40) In the above step S9, most of the straw is returned to the field after being crushed.

(41) In the above step S10, the water flow speed should be well controlled during the capturing process, and the flow speed should adopt a slow-fast-slow rhythm to facilitate the Tylorrhynchus capturing.

(42) In the present disclosure, as shown in FIGS. 2 and 3, an interception net 8 is installed at the inlet of the water inlet pipe 6, and the side section of the interception net 8 is W-shaped structure, the interception net includes a solid section 803 extending along the inner wall of the water inlet pipe 6.

(43) After the temporary water in the water inlet channel 5 enters the water inlet pipe 6, the water flow direction is along the horizontal direction of the water inlet pipe 6. The interception net 8 is designed as a W-shaped cross-section structure, and the bent top of the W structure is designed as a small grid dense area 801, and between the bent top is designed as a large grid evacuation area 802 In this way, when the temporary water in the inlet channel 5 enters the inlet pipe 6, the water flow first touches the top of the inward bent in the middle of the interception net 8, but because the top of the inward bent is designed as a small grid dense area 801, large particles debris and predators move along the W-shaped net surface on both sides of the top of the inward bent, passing through the large grid evacuation area 802, but because the grid of the large grid evacuation area 802 generally only allows slightly larger sand or pebbles to pass through, the predators cannot pass through the grid. Therefore, the predators gather along the top of the large grid evacuation area 802, but because the top of the bend is a small grid dense area 801, coupled with the impact of water flow on the axis, the water flow forms a vortex shape in the interception net 8, and most of the water flows through the large grid evacuation area 802, thereby ensuring the normal flow rate of the water flow, and at the same time, intercepting the predators in the inlet channel 5, to increase the reproduction speed of the Tylorrhynchus.

(44) As shown in FIGS. 4-8, the water inlet control assembly 7 includes an upper ring 701 and a lower ring 702 installed in the inner cavity of the water inlet pipe 6.

Wherein, the guide rods 711 at both ends of the guide groove 710 are fixedly connected to the guide groove 710. A shielding cloth 712 is arranged under the guide rod 711. When the shielding cloth 712 is unfolded, it is closely attached to the outer end of the guide hole 713 to prevent the water in the water inlet pipe 6 from overflowing the pipe wall.

(47) When it is necessary to supply water to the field, rotate the adjusting nut 709, move the movable rod 706 out of the mounting groove of the upper clamping plate 707, push the push rod 705, and move the push rod 705 down to the lower end of the guide hole 713. During this process, the shielding cloth 712 switches from bending to flattening, tightly abuts the outer wall of the water inlet pipe 6, completely shields the guide hole 713, and prevents the water in the water inlet pipe 6 from overflowing the pipe wall. Then, rotate the movable rod 706, the movable rod 706 is clamped in the mounting groove on the lower clamping plate 708, and rotate the adjusting nut 709 to fix. The whole structure is reasonable in design, easy to operate, and has strong practicability.

The rice is harvested mechanically, and water is injected in time after harvesting to keep the water level 10 cm. When the Tylorrhynchus are sexually mature, the rice field is dried for 2 days. In the dark night, 30 cm of water enters, when a large number of sexually mature Tylorrhynchus float, open the drainage gate, and arrange a soft gauze net at the gate to catch the Tylorrhynchuss. The captured Tylorrhynchus are placed in a container with holes, and after the Tylorrhynchus are drilled out of the holes to achieve separation from the sundries, then wash twice with clean water at 18? C. and stored temporarily at 15? C.

(55) Through the above three sets of examples, three types of Tylorrhynchus-rice symbiotic comprehensive planting and breeding method mainly based on tylorrhynchus proliferation can be obtained. The three types of comprehensive planting and breeding technologies for rice with Tylorrhynchus proliferation as the mainstay are carried out respectively for planting and raising tests, and then comparing with common methods for breeding Tylorrhynchuss in rice fields, it is concluded that the survival rate and yield of Tylorrhynchus in the three groups of examples have been improved differently. Among them, the survival rate of Tylorrhynchuss in Example 3 is the highest and the value is the highest.

(56) Table 1 is a comparison table of the basic parameters of Example 1-3 between the cultivation of the Tylorrhynchus and the traditional cultivation of the Tylorrhynchus.
