A method for increasing yield of facility cabbage hybrid seed production

Abstract

The invention relates to a method for improving the hybrid seed production yield of cabbages in facility, and belongs to the technical field of vegetable farming. The method includes the steps of seeding and seedling raising, land preparation and bedding, field planting of parent materials, bolting, bee depositing for fertilization, harvesting and the like. According to the method, seed productionof hybrid seeds of the cabbages in the facility is adopted, exotic other-cabbage pollen is effectively avoided, and the purity of the hybrid seeds is ensured; in the facility, black mulching film islaid, the growth of weeds can be effectively inhibited, the method also plays the roles of cooling and moisturizing the ground, and in this way, farm operation such as weeding and watering during beepollination can be reduced as far as possible; bees and mason bees are adopted to conduct matched pollination, and the mason bees are used for solving the problem that in a facility greenhouse, illumination is deficient, the temperature is high, the activity space is small, and bee pollination is deficient; the method not only can improve the yield of hybrid seed production, but also is low in cost, and reference is provided for facility seed production of other cruciferous crops.

Description

technical field [0001] The invention relates to a method for improving the yield of facility cabbage hybrid seed production, belonging to the technical field of vegetable cultivation. Background technique [0002] Cabbage belongs to the Brassica genus of the cruciferous family, and is an insect-pollinated, cross-pollinated crop. The traditional mass seed production of cabbage hybrids is through open field seed production with spatial isolation of at least 1000 meters. For the seed production of a small number of hybrids or the exploration of a new combination seed production system, considering the convenience of the selection of seed production bases, it is a more appropriate choice to use facility greenhouses for isolation. Cabbage seeds are generally pollinated by bees, but the flowering period of cabbage is generally from mid-April to early June. The temperature in the facility is relatively high, and the lighting in the facility is weak, and bees pollination is insuffi...

AI Technical Summary

Problems solved by technology

Cabbage seed production generally uses bee pollination, but the flowering period of cabbage is generally from mid-April to early June. During this period, the temperature in the facility is high, and the light in the facility is weak, and the pollination of bees is insufficient, which greatly reduces the yield of cabbage seed production or affects the production of new combinations. evaluation of the system
