Waxy corn cultivation points
Fresh corn currently on the market is corn, sweet corn, black corn, colored corn, and the like. Production is based on waxy corn. Fresh corn requires good sputum, thin skin, fine taste, good commercial traits and medium ear, suitable for cooking and quick-frozen processing. Commodity traits directly affect the price of fresh corn. Therefore, it is necessary to select the excellent varieties and suitable cultivation techniques to ensure economic benefits. 1. Variety selection. Waxy corn is the first choice for fresh corn. Among the waxy corn varieties, white is the best, such as Zhonghao No.1 and Jingke糯2000. 2. Sowing at the right time. In the open field cultivation of Tangshan area, the suitable sowing date for spring sowing is generally from late April to early May. Seeding too early to emerge slowly is also susceptible to illness. During the summer sowing period, the temperature in the corn filling stage is above 16 °C. After the wheat harvest in Tangshan area, it can be planted until July 20. 3. Cultivation management. (1) Isolation. Fresh corn cultivation must be isolated from ordinary corn to prevent the quality of fresh corn from being affected by stalking. When the space is isolated, the distance should be more than 300 meters. When the time is isolated, the sowing period should be more than 15 days. (2) Soil preparation and fertilization. Waxy corn is the purpose of harvesting fresh fruits. In order to ensure the commodity rate and quality of the ear, the cultivation of waxy corn should be the best in loam with high soil fertility, high organic matter content, good irrigation and drainage conditions and good soil permeability. When preparing the soil, the base fertilizer should be applied, the organic fertilizer should be added, and the formula should be fertilized. Generally, 30004,000 kg of high-quality farmyard manure and 50 kg of ternary compound fertilizer should be applied per mu, and appropriate amount of zinc, boron and other micro-fertilizers should be applied. (3) Sowing. The seeding method is live broadcast, generally 60 cm in row spacing and 3336 cm in plant spacing. There are 30003300 seedlings per acre. It is advisable to use no more than 3,000 strains of large ear varieties. 4. Field management. (1) Topdressing. Topdressing should be based on the condition of the seedlings. Generally, the topdressing is carried out on 1214 leaves, and 1015 kg of urea is applied per acre. (2) Pest control. Because of the high sugar content and the high damage of corn glutinous corn, the control of corn glutinous rice is an important part of the production of waxy corn. Otherwise, it will seriously affect the quality and commerciality of waxy corn ears. Generally, BT bio-particle insecticide or Bataan soluble powder is used to prevent and control during the big bell period. It is strictly forbidden to use highly toxic pesticides with a residual effect period of more than 20 days. 5. Harvesting and sales. Because of the harvesting of tender ears, it is very important to harvest tender corn. The harvest is too early, the dry matter and various nutrients are insufficient, and the nutritional value is low. When the harvest is too late, the epidermis becomes hard and the taste is worse. The general acceptance period is 2023 days after pollination, and there are slight differences in varieties. The inspection will be started 20 days after pollination, and harvested at an appropriate time. It is best to sell corn on the same day to ensure quality.
