Isolation planting. In order to prevent crossbreeding with other corn varieties, reduce sweetness and affect quality, sweet corn must be isolated and planted. The isolation zone is required to be more than 400 meters, and the time difference isolation can also be adopted. The flowering period is required to differ by more than one month.
Fine seedlings. The sweet corn seeds are dry, the ability to germinate the top soil is poor, the germination rate is low, the seedlings grow weak, and the soil requirements are high. Generally, it should be deep-turned, flattened and shredded to make the soil loose and well-loved, creating a suitable soil environment for seed germination and seedling growth. Seeds should be selected to remove insect seeds, bad seeds, and mold seeds. The soil moisture should be suitable when planting, the sowing should not be too deep, cover the soil about five centimeters, and at the same time ensure that the soil cover is consistent, and strive to be full seedlings. Apply enough base fertilizer between the holes, and dilute 5-10 kg of liquid seed dressing with new high-fat membrane mother liquor to repel subterranean pests and isolate virus infection.
Field management. Under the condition of general soil fertility level, phosphorus and potassium fertilizers are applied as base fertilizers at one time. Water management should pay attention to flood control during the seedling period and drought prevention in the middle and late period. Due to the slow growth of sweet corn, the seedling stage is prone to grass shortage, and must be ploughed as soon as possible to remove weeds. From the jointing to the big bell mouth, timely control of corn mash, the use of low-toxic pesticides, spray with new high-fat film, can reduce pesticide toxins, while increasing drug efficiency. Penetration of roots promotes growth, increases yield, and increases sweetness
