Corn, the largest food-for-grain crop in the country, is grown throughout the north and south of the country. When does maize grow, and how does it produce high yields
Corn prefers high-temperature illumination, usually in spring and summer, depending on the climatic conditions and variety of the area. In general, seeding can begin when temperatures are above 15°c and soil moisture is appropriate. Spring planting usually takes place between march and may, and summer planting takes place between june and july. In some areas, such as high altitude or cold areas, cultivation may be required in greenhouses or sheds。
1. Land selection and consolidation
In order to achieve high yields of maize, which has a high potential for increasing production, it is important to select land that is flat, deep, well-watered and organically rich. Long periods of spring-run fertility require the application of bottom fertilizers prior to planting, followed by land rehabilitation, including tilling of soil, removal of weeds, shredding of earth, etc., in order to create a favourable environment for the growth of maize seedlings and ensure their full seedling。
Selection and sowing
Select anti-invertebrate, high-yield, high-quality maize varieties adapted to local climatic and soil conditions. Seeds need to be treated before planting, including screening, drying and dressing. Cultivation is determined on the basis of the characteristics of the species and soil conditions, with rare varieties generally growing between 3700 and 4,000, semi-cracked maize varieties growing between 4,000 and 4,500 and dense varieties growing between 5,000 and 5,500 to ensure the growth and production of maize。
Fertilizing and watering
Before seeding, bottom fertilizer is required to provide nutrients for maize growth. Fertilizers can choose organic or compound fertilizers, which are determined according to soil fertility and maize growth needs. In general, 40 per cent of acre is used for 100 kg of high nitrogen-heavy potassium-type compound fat, and in the process of growing maize, water is also required in due course to maintain soil moisture and promote maize growth and development。
I'm sorry.Field management
During maize growth, field management is required, including weeding, pine soil and pest control. Comprehensive measures, including biological, chemical and physical control, are needed for pest and disease control. At the same time, care needs to be taken to ensure rational and dense planting and to ensure ventilation of maize and increased production。
Harvest and storage
When maize matures, it needs to be harvested in time to avoid loss. Post-harvest maize requires treatment such as drying, grafting, drying, etc., to reduce moisture content and facilitate storage. Storage should be dry and ventilated to avoid impurities。
