Planting method of annual three-crop oil crops in red soil dry land

Abstract

The invention belongs to the technical field of agriculture, and particularly relates to a red soil upland annual three-crop oil crop planting method. The method includes the steps of conducting mechanical rotational tilling, land preparing and direct sowing on winter rape on the 15th to 20th in October, conducting mechanical harvesting, straw smashing and field returning on the 25th to 30th in April in the next year, conducting instant mechanical tilling and raking and land preparing after cropping of rape, sowing spring peanuts on the 25th to 30th in April, conducting harvesting on the 10thto 15th in August, conducting no-tillage autumn sesame intersowing 3-7 days before peanut harvesting, and completing one time of annual three-crop oil production, wherein the intersowing time is on the 5th to 10th in August, and autumn sesames are ripened and harvested on the 15th to 20th in October.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a method for planting oil crops with three annual crops in red soil dry land. Background technique [0002] Oil crops are an important source of vegetable oil and protein in people's daily life, and are also important industrial raw materials, occupying an important position in agriculture and national economic development. China is a big oil producer and also the largest consumer. In recent years, the domestic oil supply has been in short supply for a long time, and the self-sufficiency rate has continued to be less than 40%, and the proportion of imported oil in domestic consumption has continued to rise; , my country's animal husbandry and aquaculture are in the process of rapid development, and there has been a serious shortage of refined protein feed, with an annual gap of more than 10 million tons, and it continues to increase; edible oil has become the bul...

AI Technical Summary

Problems solved by technology

The main reasons are: First, there is potential to expand the production area of ​​rapeseed by using the winter fallow rice fields. Jiangxi has a large area of ​​winter fallow fields, and the winter planting coverage rate is only about 20%. There are still about 20 million mu of winter fallow cultivated land among the 24 million mu of paddy fields in the province, which is completely possible. Used for rapeseed production; second, the yield per unit area of ​​the three major oil crops is low and unstable
