A kind of method for cultivating non-heading cabbage seeds

Abstract

The invention discloses a Brassica rapa L.Chinensis group seed plant cultivation method. The method comprises the following steps that (1) fermented rice husks are prepared; (2) fertilization and soilworking are carried out on a seed plant nursery garden according to normal requirements, and seed plant holes are dug and aired for at least one week; (3) Brassica rapa L.Chinensis group seed plantsare pulled out of a material garden in sunny day, leaves are removed, and the seed plants are then aired in the seed plant holes; (4) seed plant field planting soil is prepared; (5) the seed plant holes are filled with the seed plant field planting soil prepared in the step (4), and covered with field soil to prevent the seed plants from lodging; and (6) watering is carried out after field planting with multiple times and small amount in each time, and the seed plants are managed normally after survival. According to the method, the characteristics of low weak retention and high air permeability of the rice husks are used, fermentation is realized via EM inocula, the rice husks are used together with coconut bran, invasion caused by harmful bacteria can be inhibited, the physical and chemical structure of soil is changed, normal growth of the Brassica rapa L.Chinensis group seed plants is ensured, and breeding of the Brassica rapa L.Chinensis group is helped.

Description

technical field [0001] The invention belongs to the field of non-heading Chinese cabbage breeding, and in particular relates to a cultivation method for high-efficiency transplanting of non-heading Chinese cabbage seeds. Background technique [0002] Non-heading cabbage (Brassica rapa L. Chinensis Group), commonly known as green cabbage and Chinese cabbage, is an important vegetable of the genus Brassica in the family Brassicaceae, and it is grown all over the country. Non-heading Chinese cabbage needs to be vernalized at low temperature to flower. Therefore, the breeding of non-heading Chinese cabbage in the middle and lower reaches of the Yangtze River needs to be planted every autumn. After the cabbage grows, the seedlings are selected and transplanted. Most of the seedlings only keep the head of the cabbage. Planted in the seed plant nursery, the seed plant (cai head) undergoes low temperature for several months, and will be pollinated after flowering in the spring of th...

Problems solved by technology

In sunny weather, the daytime temperature in the greenhouse will rise significantly again. This kind of frost for several months occasionally alternates with high temperature and high humidity in the greenhouse environment, which makes soft rot and black rot prone to occur, and the chemical control effect is poor.

[0004] The preventive measures for seed plant diseases are mainly seed plant covering with soil mixed with medicine, seed plant soaking medicine for disinfection, etc. However, the occurrence of seed plant disease is related to climatic conditions and has a certain degree of chance. Therefore, these preventive methods are short in time and unstable in effect. Moreover, a large number of drugs destroy the soil ecological environment, which is not conducive to the sustainable use of land
