Cultivation method for interplanting mustard type spring rape and flax

Abstract

The invention relates to a cultivation method for interplanting mustard type spring rape and flax. The cultivation method comprises the following steps of a1, selecting a cultivation variety; a2, preparing before sowing; a3, sowing; a4, thinning and establishing; a5, fertilizing; a6, intertilling to loosen the soil; a7, preventing damage by disease and insect; a8, harvesting in good time; a9, performing multiple sowing of Chinese cabbage; after the rape is harvested in the first ten-day period of August, Chinese cabbage seedlings are transplanted between ridges, and about 10,000kg of Chinese cabbage can be harvested per mu. According to the cultivation method, the two crops are large in there-dimensional space interval and are breathable, the humidity of field after rainfall is difficultly increased, downy mildew and powdery mildew of the rape difficultly occur, and the occurrence quantity of aphids is small; in addition, because the air permeability in the field is good, rape plants are sturdy and tall, pods seed vigorously, and high yield is promoted.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a method for interplanting flax with mustard-type spring rapeseed. Background technique [0002] Mustard-type spring rapeseed is one of the main oil crops in Shanxi Province, which is very important to the lives of local people. In 2010, the sown area of ​​spring rapeseed in Shanxi Province was nearly 100,000 hm 2 , has declined slightly in recent years. Most areas in northwestern Shanxi are mountainous and hilly, with an average annual rainfall of 400 mm and a frost-free period of about 100-130 days. Spring rape is drought-resistant, cold-resistant, barren-resistant, high-yield, high in oil content, and has an average crude fat content of about 38%. The local people welcome it. [0003] The current production status of spring rapeseed: From late June to early July, spring rapeseed is growing in the silique stage. With the increase in the number of siliques, the plants appear "...

AI Technical Summary

Problems solved by technology

At this time, the growth of the plants is intertwined, and the plants near the periphery can be treated with medicines, but it is impossible to control the whole plot with medicines, and the pests are allowed to develop; moreover, due to the high temperature and high humidity in the field, the occurrence of downy mildew and powdery mildew is also inevitable. It is quite serious, the leaves of the plant are almost lost, the photosynthesis of the plant is hindered, the maturity time of rapeseed is accelerated, and the grain plumpness is not enough, which greatly affects the normal growth of local rapeseed and causes great economic losses. The production of rapeseed is generally reduced by 30%- 50%
