Sesame no-tillage sowing method under barley and ganoderma lucidum rotation mode

Abstract

The invention discloses a sesame no-tillage sowing method in a wheat and ganoderma lucidum rotation mode, which comprises the following steps: 1, normally planting wheat from the middle ten days of October to the middle ten days of May in the next year; 2, in the middle of May, 1-3 days before wheat harvesting, sesame seeds are sprayed with an airplane; thirdly, a harvester is normally used for harvesting wheat, and wheat straw is normally smashed through the harvester; 4, after sesame seedlings emerge, topdressing is carried out after raining, and other management is the same as conventional field planting management; the wheat and ganoderma lucidum rotation field adopts a no-tillage aerial seeding technology, so that the mechanical rotary tillage cost can be saved; (2) the sowing time of the sesame is advanced by about 5 days, and the sesame yield increase is promoted; (3) compacting by a crawler belt of the harvester and covering by the crushed wheat straws to form a good sesame seedling emergence environment, so that the sesame seedlings are orderly, neat and strong; (4) fine topdressing can be carried out according to the growth vigor of the sesame in the later period, and fertilizer and cost are saved.

Description

technical field [0001] The invention relates to the technical field of wheat sesame rotation planting, in particular to a no-tillage sesame sowing method under the wheat sesame rotation mode. Background technique [0002] The planting area of ​​sesame in the country is about 7 million mu, mainly concentrated in Anhui, Henan and Xiangyang, Hubei. Among them, the area of ​​wheat and sesame rotation is about 4 million mu; the wheat sesame rotation mode is one of the main sesame planting modes in my country; [0003] At present, in the process of maizhi rotation, the main method of sowing sesame is: after the wheat is harvested, it is sown by mechanical rotary tillage. The mechanical cost of the existing sowing mode is relatively high; after the country completely prohibits the burning of straw, the treatment of straw is also a waste of money. The cost is low, and the straw has a certain degree of influence on the germination and seedling growth of sesame. Therefore, it is urgen...

Problems solved by technology

[0003] At present, in the process of maizhi rotation, the main method of sowing sesame is: after the wheat is harvested, it is sown by mechanical rotary tillage. The mechanical cost of the existing sowing mode is relatively high; after the country completely prohibits the burning of straw, the treatment of straw is also a waste of money. The cost is low, and the straw has a certain degree of influence on the germination and seedling growth of sesame. Therefore, it is urgent to explore a set of no-tillage technology to reduce the cost of machinery and improve the germination rate and growth conditions of sesame. A no-tillage sowing method of sesame under the wheat sesame rotation mode
