Insect pests of rice growers have been annoying problem, today small teach you a few quick and effective method for it!
1. foot types, sterile seedling, planting density for the current field to ensure that farmers use seed less ubiquitous phenomenon, to promote "multi-pound of seed, pounds of grain income", namely rice field mu 2 kg of hybrid seeds, rice 1.5 kg with hybrid seeds. And all use in dry nursery nurse when sowing seed dressing seed dressing, seed dressing agents on seedling dry nursery nurse has dwarfed promote tillering, for fertilizer, cold, drought effect, the amount of rice medicine, seed ratio of 1:6 , rice medicine, seed ratio of 1:4 throwing 434 acre field of rice seedling tray hole 50 to 55, 20,000 ~ 22,000 points;. throw 434 acre field of rice seedling tray holes 45 to 50, 1.8 million to 2.0 Wan points per hole average of 1 to 2 kinds, in order to ensure effective field planting density and spike.
2. scientific fertilization, against premature aging, to ensure the nutritional needs of Paddy Rice scientific fertilization, to change the past, "a shelling" fertilization habit, the "before and after nitrogen shift" to ensure a balanced fertilizer requirement of rice requirements. Flexibility to determine fertilizer based on soil texture and fertility levels, generally 10 to 15 kg of nitrogen fertilizer, nitrogen, phosphorus and potassium ratio 1:0.5:1, nitrogen fertilizers, potash application rates by basal, tillering, panicle 5 :3:2 proportion progresses, other organic fertilizer, phosphate fertilizer and trace elements in all other base fertilizer. After heading per acre with 100 g of potassium dihydrogen phosphate, Penshibao 10 ml or 90 grams of amino acids and other fertilizer, 50 kg of water, 1 spray every 5 to 7 days, and even spray 2 or 3 times, prevent premature aging plants, increase grain weight and seed setting rate.
3. tube well water, good sun field, Paul leaves promote healthy root growth of rice tube general principle is to achieve shallow water tiller, timely Shaitian, thin water panicle initiation and heading, Dry wet strong seed. Turning green field surface for 2 to 3 cm deep water; tillering that is kept for 20 days after transplanting shallow alternating wet and promote faster hair early tillering and relevance of foot tiller. When the total number of tiller population reaches about 80% of the target number of seedlings spike (usually rice around May 20, late at around August 20) to start off the water views Shaitian, the peak number of seedlings population control in ears 1.1 to 1.3 times, Shaitian criteria are: heavy foot does not fall into the sun, the field to open a small crack; sun light foot just caught. Miao good, paddy field, the fruitful heavy sun, sun light and vice versa. Filling to maturity alternating wet and dry, without water one week before harvest.
