Cultivation techniques:

Basic characteristics: corn likes high temperature, and the optimum temperature for seed germination is 25 ~ 30℃. The daily average jointing period is above 65438 08℃. The average daily temperature from heading to flowering is 26 ~ 27℃. Corn can grow on sandy soil, loam and clay. The suitable soil pH value of maize is 5 ~ 8, and the optimum pH value is 6.5 ~ 7.0. Salt and alkali tolerance is poor, especially chloride ion is harmful to corn.

2. Site selection: Corn has developed root system, strong adaptability and no strict requirements on soil types. However, corn plants are tall and have many roots, so it needs to absorb a lot of water and nutrients from the soil. Therefore, it is generally necessary to choose plots with flat terrain, deep soil layer, loose texture, good permeability, medium fertility and good water and fertilizer conservation in order to obtain higher yield.

3. Choose a good variety. The corn seeds we grow are all hybrid seeds. In layman's terms, we plant it once a year. We mainly use its heterosis to improve the yield and quality, disease resistance and stress resistance of corn. We don't choose to plant every other year, mainly because of low germination.

4. Apply sufficient base fertilizer and formula fertilizer: The main function of base fertilizer is to improve soil fertility, improve soil physical properties, loosen soil, facilitate microbial activities, timely supply nutrients at seedling stage, promote root development, and create good environmental conditions for cultivating strong seedlings.
