What is the meaning of strip compound planting of corn and soybean, and the difference between interplanting and intercropping

Corn-soybean strip compound planting is an innovative and developed planting mode of double cropping in one season on the basis of traditional intercropping and interplanting. At present, most of the pilot projects are two rows of corn and two to four rows of beans, so it is called strip compound planting. There are two planting patterns, namely, corn and soybean co-sowing, corn and soybean strip intercropping, and corn and soybean strip intercropping in the middle and late stage of corn growth. Corn-soybean strip compound planting has the advantages of high yield, mechanization, sustainability and low risk, which greatly solves the land competition problem between soybean and corn.

1. What do you mean by strip compound planting of corn and soybean?

1, corn-soybean strip compound planting is an innovative planting mode of double cropping in one season on the basis of traditional intercropping and interplanting. It's not a row of corn and a row of beans. At present, most of the pilot projects are two rows of corn and two to four rows of beans, so it is called strip compound planting.

2. The biggest advantage of corn-soybean strip compound planting is that it solves the land competition problem between soybean and corn, and can harvest one more season of soybean under the condition of ensuring that corn basically does not reduce production and stabilize production. Compared with conventional technology, this technology has the advantages of high output, mechanization, sustainability and low risk, and realizes the matching of improved varieties and good methods, a win-win situation in production ecology and a double income for farmers.

3. Corn-soybean strip compound planting includes two types: one is strip intercropping in which corn and soybean are sown at the same time; The second is to sow corn first, and interplant soybean in the middle and late stage of corn growth.

Second, the difference between interplanting and intercropping

1 and * * * have different growth periods.

* * * The difference in the length of the same growth period is the biggest difference between interplanting and intercropping. Among them, the growth period of interplanting is very short, generally not more than half of the whole growth period of interplanting crops; In intercropping crops, the growing period accounts for at least half of the whole growing period of crops.

The growing seasons of these two crops are different.

The two crops interplanted have different growing seasons; The growing seasons in intercropping crops are basically the same.

3. There are different ways to improve the utilization rate of light energy.

Intercropping can improve the utilization rate of light energy by prolonging the illumination time and concentrating on the timely and intensive utilization of light and hot water resources; Intercropping can increase the area of photosynthesis, intensively use the light and hot water resources in space, and improve the utilization rate of light energy.
