Abstract

The invention relates to the technical field of agricultural planting, and discloses a strip composite corn-soybean planting method. The strip composite corn-soybean planting method adopts a corn planting strip / soybean planting strip alternating mode, the corn is planted before the soybean, a corn strip comprises two rows of corns, the row spacing of corns in each strip is 46 to 50 centimeters, an empty strip the width of which is 150 to 154 centimeters is prearranged between every two corn strips for planting soybeans, one soybean strip comprises 2 to 3 rows of soybeans, the row spacing of soybeans in each strip is 32 to 44 centimeters, and the spacing between adjacent corns and soybeans is 45 to 53 centimeters. By the strip composite corn-soybean planting method, corns and soybeans are arranged reasonably, interspecific benefit between the two kinds of crops is fully played, the yield of corns and the yield of soybeans are improved simultaneously, and the method can be widely applied to the agricultural field.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a corn-soybean strip compound planting method. Background technique [0002] Corn is the second largest grain crop in my country and the grain crop with the highest total output in the world. Corn has a large planting area and a wide distribution in China. It is the crop with the largest area and yield potential among dryland grain crops, and it is also one of the main grains for people in northern and southwestern mountainous areas and other dry valley areas of China. In addition to food, corn is also widely used in the fields of feed and industrial raw materials, such as the production of livestock feed, papermaking, brewing of shochu, and production of industrial alcohol. Because corn has outstanding advantages in many aspects, its demand is increasing, and it is one of the important crops in our country. Similarly, soybean is also an important crop in my count...
