The invention discloses a condensed-planting and high-yield cultivation method for hybrid seed production of Xinjiang honey melons. According to the condensed-planting and high-yield cultivation method, an under-film double-row drip irrigation mode is adopted, the density of female plants is increased to 5500 plants / mu, and primary pruning is performed to remove all side vines (buds) and keep one main vine when the main vine grows to 10cm; each plant is subjected to pollination by one female flower, all side buds on the entire main vine are removed during pollination, pinching is performed, a water-soluble N (nitrogen), P (phosphorus) and K (potassium) water-flush fertilizer is applied with water drops immediately after pollination, and thereafter, the fertilizer is applied in water drips once for every 5-7 days, wherein the N, the P and the K are formulated according to the mass ratio of 24: 6: 10. The condensed-planting and high-yield cultivation method has the advantages that by means of performing water-drip fertilizer application once for every 5-7 days after primary fertilizer application, nutrition supply of pollinated honey melons is guaranteed, premature senility of the vines is prevented, the fruit setting rate is guaranteed, and growing of each honey melon is guaranteed; the number of cultured honey melons is increased, land is utilized reasonably, water resource is saved, fertilization is facilitated, the degree of field moisture is decreased, pest and disease damage is reduced, and the purpose of increasing the yield of honey melon seeds is achieved.

The invention relates to a production method for pepper hybrids. The production method comprises the following steps: (1) sowing seeds of pepper half-sterile line female parent; (2) sowing pepper stock and male parent seeds when the half-sterile line female parent grows for 1.5-2.5 months; (3) removing pollen plants after the half-sterile line female parent flowers; (4) grafting twigs and branches, taken as scions, of the female parent without pollen onto the stock; and (5) performing pollination when the scions and male parent of the grafted seedlings flower, thereby acquiring the pepper hybrids after fruit is ripened. According to the planting method, the problem of 50% of fertile plants can be thoroughly solved; the pollination is timely and efficient; the yield is increased on the basis of ensuring purity; as the grafting position of the stock is under the cotyledon, the growth point of the stock is removed, the operation of cutting lateral branches while pollination is omitted, the risk of influence on purity caused by incompletely cut lateral branches is avoided, the cost is saved, and the seed production is safe.

The invention relates to the method for improving the yield of cucumis melon hybrid seed production and belongs to the technical field of plant breeding. The method is characterized by comprising the steps that when a main vine grows to the length of about 20 cm, four to five main leaves are kept for pinching; four to five side vines are kept, cross pollination is carried out on two to six female flowers of each side vine, and cross pollination is carried out once at nine o'clock to ten o'clock in the morning and once at four o'clock to six o'clock in the afternoon; two to three fruits are kept for each side vine, and when the diameter of each fruit is 10-16 cm, a soft towel disinfected through 75% of ethyl alcohol is used for wiping off the epidermal hair of the young fruits; one to three days after wiping is carried out, 0.1% of Ca (NO3)2 is sprayed on plants and fruit surfaces one to two times in the morning on a sunny day, six to ten fruits are kept for a single plant, and seeds are harvested after the fruits are mature. The method is simple and easy to implement, capable of greatly improving the yield of the cucumis melon hybrid seed production and saving the land cost, and suitable for large-area seed production of cucumis melons.

The invention discloses a method for improving the yield of hybrid seed production of sweet potato groups. The method provided by the invention comprises the following steps: 1) selection of seed production base; 2) selection of seed production parents; 3) transplanting and post-planting management; 4) removal of impurities and diseases; 5) topping and scaffolding; 6) ) harvesting of seeds; 7) drying and storage of seeds. The beneficial effects of the present invention are as follows: 1. An isolated area is set, which avoids the possibility of hybridization of other non-target parents and improves the quality of seed production. 2. Only one type of sweet potato is planted, which increases the probability of passing the identification of the offspring. 3. Minimize the risk of spreading sweet potato pests and diseases through isolated trial planting and epidemic detection, effectively avoiding the spread of sweet potato pests and diseases. 4. By removing the main vines, more side vines can be obtained to increase the flowering volume and ensure the fruit setting rate. 5. Plant nectar plants around and in the middle of the seed production field to help attract bees to pollinate and increase seed production. The seed production method of the invention lays a foundation for the cultivation of new sweet potato varieties.
