These good methods of corn seedling must be seen

Seeding and seedling cultivation is the key to corn cultivation. It is necessary to master the suitable sowing time and improve the quality of sowing in order to obtain higher yield and economic benefits. Using appropriate seeding techniques, fresh corn can be raised in the morning; the spring popcorn period can be avoided in the “fine rain” season to reduce the adverse effects of high temperature and drought on corn grouting; the summer maize can avoid buds and prolong the post-grouting time. According to the purpose of planting, soil conditions, climate characteristics, etc., the seedlings are transplanted and broadcasted to achieve the purpose of regulating the sowing date and increasing the income. Seedling transplanting can be planted early, saving seeds, easy to get early seedlings, whole seedlings and Qi Miao. Especially for sweet corn varieties, the buds are weak, and it is advisable to use seedling transplanting to ensure full seedlings and strong seedlings. Strengthen seedbed temperature and water management during seedling to prevent burning seedlings. The seedling raising methods include seedling seedling raising, nutrient seedling raising, seedling seedling raising, and paper tube seedling raising.

Seedbed seedling: The ratio of seedbed to field area is 1:50. The seedbed is made into a small raft with a width of 1.2 to 1.5 meters, and a 2 cm thick substrate or fine sand is used as a separation layer at the bottom, and a 10 cm thick nutrient soil is placed, and the square is divided into 5 square centimeter squares. The water is irrigated one day before sowing, and the soil is disinfected in combination with watering. Seeds are planted with 1 seed per plant, covered with soil 3 to 4 cm thick, and watered slightly after compaction to ensure that the bed soil is moist. The mulch is covered with a mulch, and an arch shed is added, and the film is compacted with soil. When the seedlings are 2 leaves and 1 heart, the seedlings start to grow and prevent the length. 5 to 7 days before transplanting, the seedlings will be started. The greenhouse will not be covered by day and night, the watering amount will be controlled, the seedbed will be kept dry, and the seedlings will not be wilted, so that the seedlings can be trained in cold and drought to facilitate transplanting. In the case of cold current below 0 °C, the membrane should be protected from freezing at night. When the temperature of the film is up to 12 °C, the method is to transplant the seedlings by means of puncture, and the soil is compacted after planting, and the root water is poured and the film is covered.

Nutritional seedlings; the prepared nutrient soil is made into a cylindrical nutrient bowl with a diameter of 6 cm and a height of 6-8 cm by using a pottery device, and the nutrient meal is discharged on a flat seedbed, and the bottom layer is 1 to 2 cm thick. Fine sand to prevent root damage when seedlings. Seeding, cover film, seedling management and seedling bed seedlings. Through its own carrier function, nutrition é’µ can improve the rhizosphere environment of the seedlings, which can not only ensure the supply of nutrients, but also not easy to damage the roots when transplanting, and can promote the growth of corn, and the effect of increasing yield is remarkable.

Paper tube seedling: The unfolded paper tube is fixed on the seedbed with a wooden stick or the like, and is filled with nutrient soil. Sowing, seedling management and transplanting are equivalent to nutrient seedlings.

Plug seedlings: Spread the plate on the seedbed, gently press it into the soil to prevent the overhead, surrounded by soil compaction, filled with nutritious soil in the cup-shaped hole, the nutrient soil is 1 cm away from the mouth. One day before sowing, water was irrigated, and one seed was planted at each hole. The depth was not more than 0.5 cm. The soil was covered with nutrient soil and the thickness of the soil was 0.5 cm. The double-layer membrane was covered and the membrane method was used to raise seedlings. Sowing to the standing needle Qi Miao for the sealing period, after the seedlings to remove the flat film, after the sunny day, the two shed film, ventilation and cooling. The soil is not white, and the water is not replenished when there is dew on the tip of the seedling. When the seedlings were 2 years old, the individual plants were perforated on the mulch and the cover soil was properly compacted. The seedling seedlings save labor compared with the nutrition nursery, and the seedling time is shorter, only 6 to 7 days, which can alleviate the contradiction of spring farming. The seedlings transplanted to the roots of the field are fastened, the absorption capacity is strong, the growth potential is strong, and the slow seedling stage is shorter than the nutrient seedlings, which can live 5 to 7 days earlier.
