Planting method for selenium enrichment high-yield pakchoi

Abstract

The invention relates to the technical field of agriculture planting, in particular to a planting method for selenium enrichment high-yield pakchoi. The land for growing field crops is ploughed, bedding is conducted, seeding grooves are dug in the furrow, seeding cavities are dug in the original seeding grooves, pakchoi seeds are immersed in diluted gulonic acid mother liquor and then subjected to broadcast sowing into the seeding cavities, and after the pakchoi is sown, selenium enrichment fermentation liquor is poured into the cavities one time every five days; and leaf fertilizer is additionally applied one time after the pakchoi is sown for 22-25 days. The method is adopted for planting the pakchoi, the obtained pakchoi is more environment-friendly and healthy, the rest of methods do not need to be adopted for disease control in the planting period, the total occurrence rate of various diseases in the planting period is lower than 0.02%, and the content of selenium in the pakchoi ranges from 17.94 micrograms / kg to 18.33 micrograms / kg.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a planting method of selenium-enriched and high-yield pakchoi. Background technique [0002] Chinese cabbage is a vegetable native to East Asia. It is a close relative of Chinese cabbage (heading Chinese cabbage). It is distributed all over the country and is widely cultivated in my country. Chinese cabbage is a cultivated plant of the genus Brassica (Mustard) with edible stems and leaves. It is a one-year or two-year herbaceous plant. It is often cultivated as an annual. The plants are relatively short, with shallow roots and well-developed fibrous roots. The leaf color is light green to dark green, the leaves are obovate or oval, the leaves are smooth or wrinkled, a few have fluff, the petioles are thick, white or green, no balls, the flowers are yellow and the seeds are nearly round. According to the measurement, pakchoi is a vegetable containing The most rich di...

[0003] The production period of pakchoi is relatively short, and it can be harvested in 40-60 days. If conventional methods are used to sow selenium-rich fertilizers during the growth period of pakchoi to produce selenium-enriched pakchoi, the effect is average, and the selenium content of pakchoi produced is low, even selenium free
