One-dibble-multi-strain maize interplanting method

Abstract

The invention discloses a one-dibble-multi-strain maize interplanting method, belonging to the planting method of crop. The method comprises the following steps: performing land preparation, selecting seeds, seeding in good time, fertilizing and performing field management, wherein the interplanting of maize and soybean can be performed in a mode of two lines of maize and one line of soybean, one-dibble-multi-strain is adopted, the line width between maize and between maize and soybean is 60cm; close planting resistant good strains are adopted, high and low crops are combined to perform stereo-cultivation; space and light energy are fully utilized, the defects of sole cropping are corrected; compared with the traditional sole cropping, the yield per unit of maize is increased by about 50%, 520kg / mu of soybean can be obtained; the benefit of the method is remarkable; and the method adopts mechanized planting, thus time and labor can be saved, crops can be planted uniformly, thinning isnot needed and the final-period management is convenient.

Description

technical field [0001] The invention relates to a method for planting crops, in particular to a method for interplanting a plurality of corn plants. Background technique [0002] In recent years, the food problem has become a worldwide problem. Shijiazhuang is one of the high-yield corn production areas in China, with a sown area of ​​4.6-4.7 million mu and an average yield of 400-500kg per mu. It is also a major corn-producing area in Hebei Province and even the whole country. However, in recent years, the yield per unit area has been stagnant, and agricultural technicians have focused more on the breeding and selection of new varieties, which also have a certain effect on increasing yields. However, there have been no breakthrough varieties in recent years. Some experts and scholars have explored and practiced on increasing the density. It proves that in the traditional cultivation method, the density exceeds 5000 plants / mu, which can easily cause severe lodging in large a...

[0004] The demand for soybeans has been increasing year by year in recent years. Soy products and oil extraction have increased the demand for soybeans. However, due to the limitation of planting methods, the per unit yield has been low and the benefits are low. Farmers are generally reluctant to plant
