Cotton intercropping sweet corn yield increase
June 07, 2021
In the dilemma that the area of cotton fields is declining year by year and the benefits of cotton-planting are gradually deteriorating, how to get out of the predicament and farmers in the cotton area have conducted some explorations on the farming system. They have achieved better results by using the method of interplanting Sweet Corn with cotton, per mu. Compared to single-planted cotton, it can increase income by 600-800 yuan. Their experience can be used as a reference for cotton farmers in cotton fields.
First of all, choose a good supporting variety. During the growth and development of cotton and corn, in order to make full use of land and space, it is necessary to use varieties that do not compete for land, compete for fertilizer, win light, and other symbiotic contradictions. Cotton can be used for genetically modified hybrid cotton varieties, and sweet corn can be used for Huatian No. 3 and Huatian. No. 8, Ketian 111, sweetened 16 and other varieties.
Second, determine the planting method and density.
Cabin width is generally 2 meters (including ditch) as well, each row of cotton on both sides of the box, cotton row lined with a row of sweet corn. The average row spacing of cotton is 1 meter, the spacing between the rows is 0.4-0.5 meters, and the density is 1400-1500 per mu. The corn spacing is 2 meters, the spacing is about 18 centimeters, and the density is about 1800 per mu. Each corn can receive one ear of maize (cob), and where the density is more dilute, each corn can also receive two ears. The wholesale price of each fresh sweet corn ear can be sold for 0.5-0.6 yuan, and the retail price is About 1 yuan, harvesting began around June 20, harvesting was completed before the end of June, and the benefits were considerable. This intercropping pattern not only increases the income, but also has no effect on the growth and development of the cotton in the middle and later stages and the field operation and management.
Third, the branch fertilizes and nutrients are shared.
The sweet corn used nutrition seedlings in the mid-March, depending on the weather conditions. It used 0.7-0.8 pounds per acre and transplanted it from late March to early April. After the planting, a 60 cm wide plastic film was covered. Cotton is sown in late April and mid-April and transplanted in late April to early May. Before transplanting corn, on its line, it applies 80 kg of nitrogen, phosphorus, and potassium fertilizers per mu, and another 20 kg of urea, 10 kg of potassium chloride, or potassium sulfate. Fertilizer application of urea 20 kg. Before transplanting cotton, each sub-fertilizer (including amino acids, microbial strains, phosphate fertilizer, and urea) 10 pounds per mu, according to the cave, it is beneficial to slow seedlings and strong seedlings. Then apply the bud fertilizer, apply flower bell fertilizer, and apply peach fertilizer.
Fourth, prevent weeds and prevent lodging.
In order to alleviate the symbiotic contradiction between cotton and corn, both have good living space. For the weed damage, we must first apply herbicides to purify the soil. The optional herbicide is 38% of atrazine suspension agent 300-mu per mu. 400 ml, or 50% acetochlor 120-250 ml, or 50% duo Mixture 200-300 ml, or 72% Dole EC 150-200 ml, spray 100-120 pounds per acre. In order to prevent the lodging of cotton, the hole can be made into a 45-degree angle when the seedlings are planted with a transplanting device. If the plant is planted in the north-south direction, the entrance will be inclined towards the south. If the plant is planted, the entrance will be tilted to the east. Second, the old strong seedlings that can be used in cotton are planted deep so that the surface of the nutrient bowl is 5 cm below the surface of the ground. Third, the width of the cotton can be covered and the corn can be returned to the field after the corn is harvested. Green manure can also prevent cotton lodging better.
