A method is provided for obtaining new distant germplasm of intergeneric hybridized potato based on grafting-mentor, including the following steps: (1) using young branches, which are growing well, free of diseases, non-lignified, and from an upper part of Lycium as rootstock; (2) using seedlings of diploid primitive cultivated potato with 2-3 unfolded leaves as scion; (3) grafting; (4) conducting post-grafting management; (5) obtaining distant hybridized germplasm by using potato flower buds from the grafted plants for pollination, obtaining seeds of potato varieties after self-fertility, performing pre-germination on selfing seeds, obtaining true seed mini-tubers, and using these mini-tubers for further grafting and pollination to obtain distant hybridized seeds, performing tissue culture propagation on the distant hybridized seeds to obtain F1 asexual clone line foundation seeds.

Disclosed implementations for improving crop yield in arid environments. Implementations include a method comprising selecting a cover crop adapted to absorb one or more of atmospheric or soil moisture for storage in an underground portion of the cover crop, and planting the selected cover crop in a particular tract of land at a first time instance. The method additionally includes controllably terminating growth of the cover crop at a second time instance, subsequent to the first time instance, to initiate a decay phase of the cover crop to cause transfer of the moisture absorbed in the underground portion of the cover crop to soil of the tract of land, and planting a primary crop in the tract of land at a third time instance, the primary crop absorbing from the soil at least some of the moisture released during the decay phase of the cover crop.

The invention discloses gene sequences of a plant EPSPS mutant and its application in plants. As compared to the wild type, the present disclosure describes a plant EPSP synthase (EPSPS) polypeptide which comprises amino acid V mutating to amino acid A corresponding to the location at V403 or the analogous location at V403, wherein the amino acid position corresponds to the amino acid position set forth in SEQ ID NO:1.

A method for cultivating functional crops using nano organic germanium and nano organic selenium, includes performing irrigation or foliar fertilization on plants of the crops with nanoscaled organic germanium and nanoscaled organic selenium, which are prepared in nanoscale sizes by performing one or two or more selected from a method of applying physical energy (heat or pressure) to organic germanium and organic selenium, a method of applying electrical explosive energy, and a chemical bonding process, at least twice at the time when the plants of the crops are most vigorously grown and developed and at the time of maturation to bear fruit, wherein the prepared nanoscaled organic germanium and nanoscaled organic selenium are one-component materials which are dispersed in water as a solvent in a nanoscale state.
