Embodiment
[0021] A cultivation method for high-density rapeseed "oil-vegetable dual-use" no-tillage direct seeding, comprising the following steps:
[0022] S1. After the previous stubble of rice is harvested, only simple land preparation is required, no rotary tillage is required, and direct sowing (drilling) is required. After the previous crop of rice is harvested (from mid-August to the end of August), the main ditches and surrounding ditches are opened in the paddy field for drainage, and the stubble is simply cleaned up.
[0023] S2. The paddy field is sprayed with herbicide (the herbicide adopts glyphosate) seven to ten days before sowing of rapeseed to control regenerated rice and weeds. Before sowing, it is beneficial to the management of the field in the later stage. The width of the box is 2-4m. The number of drainage ditches should be increased according to the actual situation of the field to ensure smooth drainage and prevent rainwater accumulation during the transition of...

The invention discloses a high-density oilseed rape'oil-vegetable dual-purpose 'no-tillage direct seeding cultivation method, and particularly relates to the technical field of cultivation methods. The method includes the following steps that after preceding crop rice is harvested, main ditches are dug in a paddy field in time, the ditches are surrounded for drainage, and rice stubbles are cleaned up; when the air temperature reaches 20-25 DEG C and the field moisture capacity reaches 70%, compound fertilizer is directly spread on the land without rotary tillage, and direct sowing is conducted through a drill sowing method or auxiliary sowing is conducted through stay wires; thinning is carried out when rape seedlings grow to 5-6 leaf ages, and the density is about 20000 plants per mu; picking main stem flowering Chinese cabbage for one time in a bud flowering Chinese cabbage stage; topdressing urea once after picking flowering stalks, and harvesting rapeseeds as usual in a mature period. By the adoption of the scheme, the problems that rape planting is high in labor cost and low in planting benefit, a large number of rice fields are idle in autumn and winter in main producing areas of the Yangtze River basin, the oil-vegetable dual-purpose cultivation technology is standardized, the theoretical basis is weak and the like are solved, one-time flowering Chinese cabbage income is increased, the high rapeseed yield can be obtained, and the economic benefit can be directly improved by three times or above.
Description
technical field [0001] The invention relates to the technical field of cultivation methods, in particular to a cultivation method for high-density rapeseed "oil-vegetable dual-purpose" no-tillage direct seeding. Background technique [0002] Rapeseed is the largest oilseed crop in my country. The planting area in China is stable at around 110 million mu all year round, and the total output of rapeseed is about 13 million tons. Rapeseed oil is a high-quality edible oil and is deeply loved by Chinese consumers. Rapeseed oil is the largest source of edible vegetable oil in my country, accounting for more than 50% of the total amount of edible vegetable oil produced by itself. It is very important to the safety of edible oil supply in my country. . At the same time, the rapid development of my country's animal husbandry in recent years has led to a surge in demand for bulk feed protein raw materials, and the lack of protein feed resources has always been a bottleneck restricting...
