Example Embodiment

[0013] The intercropping method of corn and soybeans, the ratio of ridges between corn and soybeans is 1:2, soybeans are sown in three rows per ridge; early maturity varieties are selected, corn is sown in two rows per ridge, and the spacing of corn is 15-17cm, and the row spacing is 10-12cm The soybean plant spacing is 10-12cm, and the row spacing is 6-7cm; when three rows of corn are planted on each ridge, the corn plant spacing is 30-35cm, and the row spacing is 6-7cm; the soybean plant spacing is 10-12cm, and the row spacing is 6-7cm; Soybeans or corn on the ridge land are grown in dog bite pattern. If you choose a sparsely planted variety of soybeans, you can plant one row per row.

[0014] This kind of planting method does not need to modify the existing agricultural machinery, and the field management is the same as that of large-scale planting of corn and soybeans, which does not increase the labor intensity of farmers.

Abstract

The invention relates to a corn and soybean intercropping planting method. The planting method has a corn and soybean intercropping ridge rate of 1:2. Three lines of soybeans are sown in each ridge; two lines or three lines of corns are sown in each ridge; and the soybeans or the corns on each ridge of land are planted in a dog bite mark mode. Due to the adoption of the corn and soybean intercropping planting method, a conventional mode of planting the corns in a large area is broken through, high and short stem crops are combined to be planted in one plot of land to form a height difference, and the crops have high ventilation and high wind resistance and lodging resistance. Moreover, the corns can keep out the wind, keep out the cold and shade the sunlight for the soybeans. After the planting method is adopted, the yield of the corns is same with that of the corns planted in the large area, but the yield of soybeans is increased by 60 percent per hectare, so that the limited soil resources are better utilized and the aim of increasing both yield and income of farmers is fulfilled.

Description

technical field [0001] The invention relates to a method for planting crops, in particular to a method for intercropping corn and soybeans. Background technique [0002] Corn is an important food and feed crop. Because of its high yield and simple field management, it has been planted in a large area in my country, especially in Northeast China. Corn has been the main crop. Now farmers are planting corn in large areas, and they are planting densely. They just leave an empty ridge in the middle of five or six ridges for ventilation. Due to poor ventilation, the ears of corn are small, and the light transmission is not good. The empty ridges caused waste again, so that the limited land is not better utilized. Soybean is rich in nutrients needed by the human body, but due to its low yield, fewer and fewer farmers have grown it in recent years. Contents of the invention [0003] The purpose of the present invention is to provide an intercropping planting method of corn and s...
