First, the selection of varieties of glutinous corn hybrid Su Shi 1. The variety has the characteristics of thin, sweet, fragrant, and good taste. It is planted 2 times a year, and the whole growth period of the spring eel is about 105 days.
Second, before planting sowing seedlings must be turned over soil before the winter sun, combined with winter plowing, per 667 square meters (1 acre) deep into the decomposed organic fertilizer 1500 to 2000 kg, about 15 days before sowing with glyphosate 1 kg weeding. Use a trencher to open a good ditch with a ridge width of 1.5 meters (including a ditch).
Nursery soil nutrition configuration: 10 days before sowing should be prepared a good nutrition soil. In general, 250 kg of dry pig manure, 1500 kg of vegetable garden soil, plus 15 kg of imported potassium sulfate compound fertilizer per 667 square meters, mixed and stacked. It is advisable that the nutrient humidity should be scattered in the hands to form a group, and that falling from a height of 1 meter can be spread out. It should be sealed with a film after being well-matched and stacked for at least 10 days before it can be used for plastic tray seedlings. Seeds are sown on sunny days for 2 to 3 days before sowing, which can effectively increase the germination rate and early germination time.
Third, seedlings per 667 square meters Daejeon requires seedbed area of ​​2.5 meters 21 meters, after the ditch to do the drying ridge, pouring 600 kilograms of pig manure, finishing surface, and then drenched water, the last leveling, with 451 holes per 667 square meters 11 plastic trays, 2 sheets and 1 pair, horizontally pressing forward with wooden planks, pressing the bottom of the tray with the soil on the bed, and placing 1 seed dressing in each hole (the medicine is 1:20 double-dip liquid) Fill it with nutrient soil, sweep it with a pestle, and then use a watering pot to pour water. Soak it until it's wet. Cover the surface with a plastic film. Cover the surface of the film with a thin layer of straw (if no film is used) and cover it with dirt. After the corn shoots emerged from the earth's surface, the plastic film was peeled off in time.
Fourth, planting specifications and field management Each ridge and ridge width of 1.5 meters (including ditch), wide and narrow rows of plants, spacing of 0.1 meters, a large row spacing of 0.9 meters, a small row spacing of 0.6 meters, 4000 to 5000 plants per 667 square meters. Due to the fact that Suzi corn and common corn flour will lose their sweetness and flavor, they can be planted in isolation and planted in stages. In the 2-leaf period, spray a small amount of water with a watering can to moisten the soil before transplanting. Move the seedlings to bring the soil, cover the soil, and immediately pour the root water. In the event of rain, transplants can be postponed to the 4-leaf stage. Apply 20 kg of urea per 667 square meters. Apply it between rows of seedlings. Do not apply to seedlings to prevent sprouting. When the application time of panicle fertilizer is 13 to 15 leaves, 25 kg urea and 20 kg of zinc sulfate are applied per 667 square meters, and potassium chloride is strictly prohibited. Waxy corn is the most sensitive and sensitive period before and after tassels are drawn. It should keep about 70% of the field water capacity and try to meet the water requirement of corn growth. After heading, if there is a phenomenon that the corn leaves are weak, the leaf color above the ear section is yellow-green, and the lower leaves are withered, the panicle fertilizer should be immediately added, and 20 kg of urea should be used per 667 square meters.
5. Diseases and Insect Pests Diseases and insect pests are caused by corn borers, ground tigers, armyworms, aphids, and sheath blight, and in accordance with the principle of “mainly prevention, comprehensive prevention and controlâ€, they insist on “agricultural prevention, biological control, and physical control†and strictly follow Pollution-free production standards to prevent and control. Ground tigers are mainly harmed at the seedling stage, and 667 square meters can be blended with sautéed cabbage cake with 100% crystals of 100 grams of trichlorfon powder and 400 grams of boiled water. Corn borers, aphids, tapeworms, and sheath blight, can kill 667 square meters with 250 grams of double insecticide plus 70 grams of worms, 150 grams of trichlorfon crystals, 150 grams of wells, and 40 kilograms of sprayed fine mist. , spray it again 5 days later. Diseased plants in the field of maize must be cleared in time and brought out of the field and away from the corn planting area. The use of pesticides should be strictly prohibited 7 days before harvesting.
