Second, high-yield cultivation techniques:
Diluted seedlings in dry conditions: Under the climatic conditions in Jilin Province, about 10 April, seedlings were raised. Drought seedlings sowing rate of 150 grams per square meter sowing seeds (3 two), disk seedlings sowing every sowing 80 to 120 grams of germination seeds; throwing seedlings seedlings per hole 2 to 3, after sowing covered finely sifted mountain soil In order to improve the temperature of the seedbed, after sowing the soil should be poured once again enough water, before planting seedlings to develop 4.5 to 5.5 leaves, single seedlings tiller 1 to 2, dark green leaves, seedlings flat and strong.
Planting density: using sparse cultivation or ultra-slim cultivation, transplanting method 30 cm 20 cm (9 inch 6 inch); 30 cm 26.7 cm (9 inch 8 inch); 40 cm 20 cm (12 inch 6 inch); (50 Centimeter + 30 cm + 30 cm) 20 cm (mixed and sparsely cultivated), 2 to 3 seedlings per hole, to be transplanted in shallow water. Try to avoid the phenomenon of dense planting, multi-insertion, etc., and maximize the potential for yield increase of rice individuals through cultivation methods such as less insertion and planting.
Fertilization techniques: There is a close relationship between the yield of rice and the amount of fertilization, the fertilization period, and the type of fertilizer. High-yield fertilization should balance the required fertilizer and the fertilizer (fertilizer) in rice. After many years of trial and research, we have summarized the high-yielding fertilization techniques of rice with nitrogen fertilizer, nitrogen, phosphorus, and potassium fertilization in stages, with a total nitrogen application rate of 120-130 kg/ha; phosphate fertilizer (diphosphorus pentoxide) 50-70 kg/ Hectares, potash (potassium oxide) 70-90 kg/ha. Specific fertilization methods: 30% nitrogen fertilizer base fertilizer (basic fertilizer) before planting, 10% of tiller fertilizer (returning green manure), and 25% of manure fertilizer, applied from June 20 to June 25 to promote high-section tillering into panicle. 25% panicle fat was applied around July 5 (panicle differentiation stage) to ensure that there were many panicles. 10% of grain fertilizer was applied at full heading stage to increase grain maturity. Phosphate fertilizer 100% as base fertilizer, 70% potassium fertilizer as base fertilizer, 30% as panicle fertilizer. For rice fields with fertile soil and long-term application of farmyard manure, the amount of nitrogen fertilizer should be appropriately reduced based on perennial experience, and the amount of nitrogen fertilizer should be appropriately increased for sandy soils and soils with low fertility. Due to the low ground temperature in early stage of rice growth and the slower growth of seedlings, low-calorie cold paddy field and grassy carbon soil must not be over-used with nitrogen fertilizer. In addition to nitrogen, phosphorus, and potassium fertilizers, silicon fertilizer and zinc fertilizer should be applied to prevent the occurrence of rape blight. occur.
Moisture management technology: Moisture takes shallow-wet-run-dry management methods. Rice should be transplanted in shallow water and can not be drained or transplanted without water. The rice should be irrigated during the tillering stage (planting till June 30), raise the ground temperature and water temperature, and reach the end of effective rice tillering (about July 5), draining Liangtian, Invalid control of delivery. During the panicle differentiation (June 30 or July 5), wet irrigation, intermittent irrigation is used for low-lying land, grassy carbon land, etc. to keep the soil moist, and irrigation should be performed on the land and the leaked land in time. Shallow irrigation ensures the water needed for rice growth and development at this stage. From the ear to the grain filling stage, wetting irrigation is used to maintain root activity, prolong the lifespan of the lower leaves, and increase the maturity of grains. During the ripe period (growing to harvesting), the water is drained to enhance the vitality of the roots and prevent lodging.
Diseases, Insects, and Weed Control Techniques: Rice diseases, insects, and weeds should be primarily prevented, and the hazards should be reduced through the cultivation techniques and comprehensive control of pesticides. Honda weeding should be controlled by butachlor and glucoside for about 7 days after transplanting. During the first and the middle of June, we should pay close attention to the occurrence and damage of the rice leafminer and negative mud insects, and use dimethoate to prevent and control the enemy at the initial stage of the rice leafminer and negative mud insects. During July 5-20, we should pay attention to prevention and control of rice stem borer. Rice blast is a biological natural disease, there is no absolute resistance to the disease, it was found that Ye Yu timely fight drugs, use Fuji No. 1 or tricyclazole to control leaf alum per acre Apply 2 to 3, spray 30 to 45 kg of water (2 to 3 sprayers of water), and apply heal to the heavier patches on July 10 to 15 at the beginning of earing (5% of the ear) Conduct a second prevention (or prevention). For the field where there is no disease, the ear should be produced, and about 5% prevention should be performed.
