The invention discloses a method for improving the yield of muskmelon hybrids by using hormone treatment. The method comprises the following steps of: (1), collecting male parent flowers, namely, in the afternoon of the day before fertilization, intensively collecting male flower buds blossoming in the next day from male parent plants of muskmelon, placing in a glass bottle, keeping in a dark place; (2), selecting and pollinating female parent flower, namely, in the next day after collecting of male flowers, selecting buds blossoming in the next day from the female parent plants of muskmelon, removing anther, smearing anther of male flowers collected in the step (1) on female flower stigmas, isolating by covering with paper caps; and (3), carrying out hormone treatment on fertilized fruits, namely, 24-72h after the pollination process completed in the step (2), removing the paper caps at a temperature of 18-30 DEG C and dipping the flowers in a 2.5ppm-5ppm forchlorfenuron water solution. By adoption of the method provided by the invention, the fruit setting rate and the single-melon seed setting rate are increased, and the effects of saving the labor for pollination and increasing the yield are achieved.

The invention discloses a hybrid rice breeding method. The hybrid rice breeding method comprises: separately selecting two sterile lines with high tillering, a high stigma exsertion rate and short andnarrow leaves and a restoring line with high tillering, large ears and short and narrow leaves, carrying out test mating through the sterile lines as female parents and the restoring line as a male parent, planting the F1 generation and selecting a hybridized composition with excellent agronomic traits. The method breeds hybrid rice parents with high tillering, a high stigma exsertion rate, largeears and short and narrow-leaves. In production of hybrid seeds, leaves are not cut, 920 is not sprayed, the amount of male parent pollen is increased, the pollination obstacles are reduced, the maturing rate is improved, the seed yield is greatly improved, the dependence on labor in the hybrid rice seed production process is reduced, the seed production efficiency is improved and the seed production cost is reduced.

The invention discloses a method for cultivating schisandra chinensis. The method includes the steps that a forest of wild schisandra chinensis is selected on a mountain, 1500-2000 breeding parental plants are reserved, and other plants are removed; then, at the flowering phase of the next year, cross pollination and repeated crossing pollination are conducted on the reserved breeding parental plants, 1000-2000 excellent seeds are selected for growing seedlings after fruits are grown, and flat ground open-air cultivation and domestication are carried out under a full exposure condition; trunks of the seedlings need to be cut as low as possible in domestication, each seedling can germinate 3-4 main vines from a base part, slight cutting is conducted in the growing process, and an erected support is full of branches and tendrils; at last, seedling growing and planting are conducted on the seeds grown by the schisandra chinensis which is subjected to cultivation and domestication, and accordingly a schisandra chinensis variety is obtained. The schisandra chinensis variety cultivated through the method has obvious stress resistance, and the schisandra chinensis can still grow normally under the high temperature and slight arid condition; meanwhile, the yield of the cultivated schisandra chinensis is improved obviously compared with the yield of the wild schisandra chinensis, and the yield is about 1.3 times of the yield of the wild schisandra chinensis.

The invention provides a method for large-scale planting of high-yield siraitia grosvenorii. The method comprises the following steps of land selection and preparation, seedling hardening, planting, water and fertilizer management, pollination, field management and the like. According to the method, by combining the trellis growing time, the flowering time and the fruit maturation time in all thetreatment steps, the time from planting to trellis growing, flowering and fruiting is gradually shortened; meanwhile, the dead seedling rate of seedlings starts to be reduced, the fruit cracking rateis reduced, and the average plant yield of the siraitia grosvenorii is increased. Meanwhile, by carrying out high-yield cultivation technology research on the siraitia grosvenorii tissue culture seedlings, the appropriate planting time, transplanting mode, pollination time and the effective active time of pollen are determined, which lays a foundation for high-yield cultivation and large-scale planting of siraitia grosvenorii.
