Embodiment Construction

[0020] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work, any modifications, equivalent replacements, improvements, etc., shall be included in the protection scope of the present invention Inside.

[0021] The present invention is based on the sustainable planting mode of wheat and corn intercropping green manure, efficient resource utilization, and improvement of farmland productivity, comprising the following steps:

[0022] Step 1. Intercropping wheat and corn in the spring of the current year: the intercropped wheat and corn have a width of 110 cm, 8 rows of wheat species, 12 cm in row, 3 rows of corn seed, 40 cm ...

Abstract

The invention discLoses a sustainabLe pLanting mode based on wheat and corn intercropping green manure inserting appLication. The mode incLudes the steps that S1, in spring of a current year, wheat and corn intercropping is arranged, wherein the beLt width of wheat and corn of intercropping is 110 cm, eight Lines of wheat are pLanted at the Line spacing of 12 cm, and three Lines of corn are pLanted at the Line spacing of 40 cm and row spacing of 25 cm; S2, in the current year, after the wheat is harvested, six Lines of common vetches are cropped muLtipLy on a wheat beLt at the Line spacing of15 cm, and wheat and corn intercropping green manure inserting appLication is reaLized; S3, in the frost season of the current year, green manure covers and returns to the fieLd to reaLize annuaL covering, and water retaining and wind erosion preventing are reaLized; S4, in the next year, rotary tiLLage is performed on two crop beLts to pLant wheat and corn in exchange to reaLize inter-beLt crop rotation, potentiaL successive cropping obstacLes are eLiminated, and soiL nutrients are baLanced. In the mode, resources are efficientLy utiLized, the production capacity of a farmLand is improved, the mode is a sustainabLe pLanting mode, a traditionaL production mode can be changed, and the noveL sustainabLe agricuLturaL production mode is created.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, and more specifically relates to a sustainable planting mode based on intercropping of wheat and corn interplanting green manure, efficient utilization of resources, and improvement of farmland productivity. Background technique [0002] In the arid inland oasis irrigation area, wheat and corn are the two main crops, and the sowing ratio is greater than 50%. Due to the serious water shortage of resources, the intercropping planting mode is used to improve the water use efficiency by increasing the output per unit area. However, the high yield of traditional intercropping stems from the high water and fertilizer supply, which leads to a decline in farmland productivity and reduces the potential for high and stable crop production. Therefore, intercropping green manure in the intercropping mode can not only reduce wind erosion but also maintain high soil water content by realizing ann...
