Embodiment 1

[0028] 1. Sowing seedlings:

[0029] The female parent was sown and raised in the greenhouse around February 15 (± 5 days). Before sowing, the germination treatment was carried out at variable temperature. After the whitening, put it into a refrigerator at 4°C, treat it at a low temperature for 4-6 hours, and start sowing. Use 50 hole (specification) hole trays to carry out seedling cultivation, sow 2 seeds in each hole, around February 25 (± 5 days), and the seedling age is 1 leaf and 1 heart for colonization. The male parent raised seedlings around February 10 (±5 days), and the key points of sowing were the same as the female parent. Seedling routine management.

[0030] Treatment of attracting females and attracting males: Treatment of attracting females of female parents: 1 seedling with one leaf and one heart, spray 40% ethephon 80-100ppm once in the seedbed, and spray again at intervals of 2 days, if the female parent is a female material, no spraying is required.

Abstract

The invention discloses a cucumber secondary seed propagation method. The present invention starts artificial hybridization and pollination from late March to early April, adopts low-node artificial pollination, and the melons are ripe in the first and middle days of May, and the seeds are collected after the melons are harvested; the sunshade treatment is started in the first ten days of May; the first time After the melons are harvested, remove the female flowers below the growth point in time, and take measures to promote the growth of seedlings; carry out the second pollination from the end of May to the beginning of June; adjust the time of sowing seedlings and planting of the male parent for the second time according to the pollination time; After pollination, wait for the seeds to mature and collect seeds. The present invention solves the problem of "premature senescence of seed plants after the first pollination" by reducing the node position of the first pollination, regulating fertilizer and water in the middle and later stages, and managing shade in the middle and other periods. After harvesting the melons for the first time, technical measures such as restoring the growth of the plants and regulating the flowering period of the male parent were used to effectively prolong the life of the plants and increase the seed yield, thereby realizing the secondary pollination and seed collection of cucumber plants.

Description

technical field [0001] The invention relates to a method for secondary breeding of cucumbers, belonging to the technical field of cucumber breeding. Background technique [0002] Cucumber is a very common and popular vegetable in China. Because it is refreshing and delicious, it can also be eaten as fruit (especially fruit cucumber). Cucumber is an important facility-cultivated vegetable in my country. The planting area ranks first among facility vegetables. In terms of production, it has the characteristics of many planting stubbles, rich variety types, and large amount of seeds used. Cucumber cultivars are an important part of supporting the cucumber industry. [0003] Breeding technology of improved varieties is an important technical link to ensure improved varieties of cucumber. The current conventional cucumber seed propagation technology is all about collecting seeds after one pollination. After the traditional cucumber is pollinated, the reproductive growth compet...
