Problems solved by technology

In the Northeast farming-pastoral transition area, corn is an important food crop and fodder crop, and alfalfa has a strong ability to fix nitrogen and can prevent wind and sand. Therefore, the intercropping of the two can not only ensure food security, but also improve the ecological environment. However, there are no reports on the effects of different intercropping distances on the intercropping system of corn and alfalfa. Determining the optimal intercropping distance and row ratio of intercropping between corn and alfalfa will help to build a reasonable corn / allfalfa intercropping population in production. , to provide a scientific theoretical basis for fine-tuning the nutrient utilization of the corn / alfalfa compound population in production practice, and it is of great significance to promote the development of ecological agriculture in the Northeast agro-pastoral transition zone

Abstract

The invention provides a corn and alfalfa intercropped planting method. The method includes: sequentially and cyclically planting corn belts and alfalfa belts, wherein a corn planting row number of each corn belt is 2-6, an alfalfa planting row number of each alfalfa belt is 5-7, and the distance between each corn belt and the adjacent alfalfa belt is 20-40cm. The corn and alfalfa intercropped planting method has advantages that compared with a single corn planting method, the total yield of corn and alfalfa is increased by 2.1 times, and economic benefits are increased by 2.4 times; compared with a single alfalfa planting method, the total yield of corn and alfalfa is increased by 1.3 times, and economic benefits are increased by 1.1 times, so that high yield and high efficiency are realized; in addition, high ecological benefits are achieved, alfalfa which covers the earth surface all year round can realize wind prevention and sand fixation and improve the ecological environment, and accordingly wind-sand damages of deteriorated grassland can be reduced effectively.

Description

technical field [0001] The invention relates to the field of intercropping of crops, in particular to a method for intercropping corn and alfalfa. Background technique [0002] Northeast agriculture and animal husbandry interlaced area is an interlaced area combining agriculture, forestry and animal husbandry, and is an important commodity grain and animal husbandry base in my country. On the one hand, for a long time, due to harsh natural conditions such as low vegetation coverage, strong evaporation, strong sandstorms, etc., as well as irrational use by humans, the food security, ecological environment security and sustainable development of animal husbandry in this region have faced severe challenges; On the other hand, field studies have shown that the amount of nitrogen fertilizer applied in my country's farmland far exceeds the world level, but more than two-thirds of the nitrogen fertilizer is not absorbed by crops, but pollutes water and air through evaporation and le...
