I. Seed standard and variety selection
1. Summer sowing maize selection medium, early maturing (spring sowing selection, late maturing), big ear, high seeding rate, good resistance, good commodity variety.
2. Summer sowing soybeans choose medium grain type, medium and early maturity (Spring sowing selection, late ripening), high yield, good resistance, good quality varieties.
3. Select the national standard corn and soybean seeds with high bud rate and bud potential to ensure that the seedlings are full and Miao Qi and the plant size is the same.
Second, the planting mode
1.3 rows of corn for three rows of soybeans, corn row spacing 60 cm, hole spacing 35 cm, one-hole double plant, Mu Liumiao 3600 strains (1800 points) about; corn and soybeans spacing 40 cm. Soybean spacing is 40 centimeters, the distance between the points is 20 centimeters, and the number of pairs of plants in one hole is 7,100 strains (3,550 points) per mu.
2.2 Rows of soybeans were intercropped with 4 rows of soybeans. The corn spacing was about 50 centimeters, the distance between the points was 30 centimeters, and the number of pairs of plants in one hole was 3,200 (1600 points) per mu. The spacing between corn and soybeans is 40 cm. Soybean spacing is 40 centimeters, and the distance between the points is 20 centimeters. There are two plants in one hole and about 14,000 strains (7000 points) in Mu.
Third, water and fertilizer input
1. Apply 30 kg of special compound fertilizer for corn at the end of sowing maize. During the big corn horn period, 30 kg of urea was applied per acre, and watering was done in case of drought.
2. 15 kg of special compound fertilizer for soybeans will be planted with the sowing soybean acres, 10 kg of urea will be topped with flowering, and watering will be conducted in case of drought.
Fourth, field management
1. Summer sowing of corn, soybeans, spraying acetochlor herbicide before seedlings. Spring sowing can be cultivated in fields.
2. When the corn plants grow to 8-10 tablets, they are properly controlled according to the conditions of water and fertilizer. Soybean flowering period is appropriately controlled according to growing conditions and water and fertilizer conditions to prevent prolonged growth and lodging. At the same time in the control of adding appropriate amount of insecticide fungicides and foliar fertilizer for a spray more defense.
3. Based on pest and disease forecast in the agricultural sector, timely control of pests and diseases.
Fifth, the advantages of corn and soybean intercropping
1. Intercropping maize and soybean can effectively improve the soil structure and it is a conservation tillage mode of cultivation. Economic benefits, social benefits and ecological benefits have been increased simultaneously.
2. The intercropping corn field fully exerted the advantage of borderline, full-grained panicles, high bulk density, and high yield; intercropping soybeans provided good ventilation, reduced the incidence of diseases and diseases of soybeans, and was conducive to the firming of soybeans, fullness of grain, and high bulk density. Intercropping of soybean and corn increased yield and income from the cultivation of monoculture maize, and also saved water and fertilizer.
Six, corn and soybean intercropping defects
Only corn can be harvested with a small corn harvester. Currently, soybeans need to be harvested manually.
The greenhouse a filled with equipment like hydroponic, irrigation, auxiliary lighting ,temperature and humidity control and also may be automatically controlled by a computer to maximize potential growth.
Hydroponics can be used to make the most use of the interior space. The relatively closed environment of a greenhouse has its own unique management requirements, compared with outdoor production. Pests and diseases, and extremes of heat and humidity, have to be controlled, and irrigation is necessary to provide water. Most greenhouses use sprinklers or drip lines. Significant inputs of heat and light may be required, particularly with winter production of warm-weather vegetables.
