Rice seedlings technical advice: First, the conventional dry seedlings 秧 秧 秧 秧 秧 秧 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 6 6 6 6 6 Key measures: 1. Seed bed fertilization. Use vegetable garden or wadi as seedbed. Leave 40 square meters of seedbed per mu of Daejeon, apply 3-4 baits of decomposed human livestock, and 10 kg of compost of fertilizer. When sowing, first leveling the flour surface, 40 square meters of seedbed with Wuxi production Zhuangshen nutrient 1 bag (2.5 kg), mix about 30 kg of dry fine soil, spread evenly on the surface, finely poured after pouring sole water, and then Sowing cover soil, laminated grass. 2, seed treatment 3, appropriate sowing. The control of sowing date of wheat glutinous rice is from May 5th to 15th, with 3 kg per acre of Daejeon, and the amount of grain in a net mash pond is controlled at about 40 kg/mu per acre. 4, dry nursery dry pipe. In dry conditions, seedlings should not be replenished under normal conditions to improve the drought tolerance of the seedlings. At the same time, it is necessary to pay attention to pouring three times of water, that is, pouring water before planting, pouring water to remove the film, and watering the film to dry the weather. Ye Shui." 5, pest and weed control. Second, plastic tray dry seedlings strong and powerful indicators: age 20-25 days old, leaf age 4-5 leaves, seedlings about 15 cm high, single-hole seedlings 2-3 strains, the hole rate within 10%. Key technologies: 1. Twisting water. Use vegetable garden or wadi for seedbeds, and drill 1.5 meters along the surface of the board for squeezing, so that the surface is finely crushed. When the surface of the board is finished, the horse water can be poured and the foot can be hoeed. 2, spread strong nutritional supplements. Press 80 plastic trays with 800 grams of nutritional supplements, add dry fine soil and spread on the surface. Use a rake and plunge into a 2 cm soil layer. 3, sowing cover soil. Three kilograms of seed per acre of Daejeon, rice seedlings first soaked to dew-white (method with the plastic tray dry education), and then evenly spread in the tray hole, after sowing covered with nutrient soil, cover species after the clearance of the remaining surface of the disk. 4, watering film. After the cover is sprayed with enough water, sprinkle a small amount of straw on the mulch, and then sprinkle the appropriate amount of straw on the mulch to avoid burning seedlings. 5, remove the film in addition to, after rice seedlings in a timely manner to remove film glue, one day after the removal, every 60 plastic plates with 30% scanfate EC 2 ml, spray 1 kilogram of water, keep the plate moist after treatment. 6, spraying Sic Bo. Without the use of strong nutrient seedlings, one seedling at the end of each leaf of the seedlings will be sprayed with 1 bag of water. Third, the plastic tray wet Yuzuo strong index: age about 18 days, leaf age 3.5-4.0 leaves, seedling height 13-15 centimeters, cavity rate within 10%. Key technologies: 1, appropriate sowing. According to the planting date, the sowing date determines the sowing date so as to leave room. 2, seed processing. The method is the same as dry bed breeding. 3, the whole board. After the water in the Dianchi Lake was filled with water, the width of the plate was 1.5 meters wide. After the surface was leveled, the plastic plates were placed horizontally in two rows to stick the surface of the plate. 4, sowing cover soil. Mu Daechi Dianchi uses species of 3.5 kilograms, and acre plate 55-60 pieces are used. Soaked seeds of rice are sprinkled in the tray holes. After sowing, they are planted with dry fine soil, and the remaining surface of the plate is removed to reveal the hole stems. 5, moist tube water. Fill the ditch with water after sowing and prohibit flood irrigation so as not to suffocate the species. After one leaf and one heart period, the main irrigation is wet, and continuous spraying is prohibited. 6, use a good strong agent. A shallow water layer was established in the 1 leaf stage of the seedlings, and 60 plates per acre were mixed with a small amount of fine soil and 800 g of Zhuangzhi agent. 7, top dressing. The seedlings at one heart and one heart are chasing and applying a weaning fertilizer, 0.2 kg of urea per 100 plates, and a shallow water layer should be set up during fertilization. Dry application should not be applied (strengthening milk fertilizer without using strong scorpion agent). Give a marrying manure 2-3 days before the set-up.
