Loess plateau corn and wheat rotation planting method

Abstract

The invention relates to the technical field of crop cultivation, in particular to a loess plateau corn and wheat rotation planting method, and is applicable to recycling of agricultural waste resources. According to the researched and developed rotation planting method of spring corn matched with winter wheat, a plant belt is used for cultivating plants, a non-planting belt is used for stacking and fermenting straws, land utilization rate is greatly increased, the decomposition time of the straws is prolonged to twelve months from original seven months, the decomposition rate of the straws isgreatly increased, soil fertility is increased by prolonging the decomposition time of the straws, use of chemical fertilizers is decreased, and recycling of straw agriculture waste resources is greatly improved. According to the researched and developed method, the applying amount of a phosphate fertilizer can be reduced by 59%, the applying amount of a nitrogen fertilizer can be reduced by 40%,the yield of the wheat and the corn is obviously increased, the contents of soil organic matters, total nitrogen and rapidly available potassium are obviously increased, and soil fertility quality isimproved. Straws of the wheat and the corn are completely crushed and then returned to fields, the straws are effectively treated, and the possibility of environmental pollution caused by straw burning is completely avoided.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a corn and wheat rotation planting method on the Loess Plateau, which is suitable for recycling agricultural waste resources. Background technique [0002] Phosphorus is one of the indispensable important elements for crop growth. It participates in various biochemical processes in plants in various ways, and plays a very important role in promoting plant growth, development and metabolism. The phosphorus needed by plants is mainly obtained from the soil phosphorus pool and phosphorus fertilizer, so the application of phosphorus fertilizer is an important means to improve the phosphorus content of the soil and increase crop yield. The ecological environment of the Loess Plateau is fragile, the soil is barren, the soil erosion is serious, and the agricultural output is low. In order to fertilize the soil and increase crop yields, farmers in the Loess Plateau currently ge...

AI Technical Summary

Problems solved by technology

Long-term large-scale application of phosphorus will greatly increase the level of available phosphorus in the soil, and the risk of water loss will increase, thus threatening the ecological environment

At the same time, long-term large-scale application of phosphate fertilizer will also lead to the depletion of limited phosphate rock resources.
