Interplanting technology of corn and soybean

Land selection: It is advisable to interplant corn and soybeans on fertile flat land. Variety requirements: The soybean variety should be a dwarf lodging-resistant variety with a growth period of 1 10- 120 days. Seed treatment: coating 65438+ 0-2 days before sowing. Scientific fertilization: 20 kg per mu for corn and 27 kg per mu for soybean.

Interplanting method of corn and soybean 1, field selection

The fields selected for maize and soybean interplanting are particular, and the flat land or hill with fertile soil is suitable, but the depression is not suitable, because the soil moisture in the depression is high, and soybeans are prone to grow white and lodging after planting, which may lead to the risk of yield reduction.

2. Variety requirements

The quality of maize and soybean varieties determines the yield, especially in interplanting mode. Soybean varieties should generally choose short lodging-resistant varieties with the growth period of 1 10- 120 days, and corn varieties should choose closely planted varieties with hard stems and raised leaves with the growth period of 120- 125 days.

3, processing seeds

After the selection of corn and soybean varieties, seed coating is carried out 1-2 days before sowing, which can not only effectively improve the emergence rate, but also facilitate the later management, thus achieving the purpose of increasing production and improving quality.

4. Scientific fertilization

When sowing corn and soybean, sufficient base fertilizer should be applied, and the corresponding fertilization parts can be installed on the seeder, including about 300 kg of corn and 400 kg of soybean, which can meet the growth needs of the two crops at seedling stage.
