First, early application, appropriate application of fertilizer The tiller fertilization rule applied during returning to the tiller period is as early as possible, generally completed within 3 to 7 days after insertion, in order to promote early delivery, and to ensure that the percentage of spikes is increased; second, it is appropriate, and it is better for the better fields. Ammonium sulphate 7.5 ~ 10 kg or urea 4 ~ 5 kg, slender Mushi ammonium sulfate 10 ~ 12.5 kg or urea 5 ~ 6 kg. If there is a good situation, it will be less applied. Only in this way can all fields reach the same level. After the rice enters the tillering stage, the growth rate is faster. If the tiller fertilizer is applied late, the amount will be too much, which will lead to a large number of invalid defects, leaf disclosure, premature closure, and poor transparency and ventilation, making the stems and leaves soft. The lodging resistance of a variety is determined by the growth of the internodes of the base of the rice plant, and the delivery period is the best period for growth. Excessive nitrogenous fertilizer during the prosperous period of delivery leads to long internodes in the base of the plant, thinning of the stalk wall, increased plant height, reduced resistance to fall, rain and windy wind after heading, and often causes lodging. After fertilization, the field should have a water layer, and it should not be drained. After being dried naturally, it should be filled with shallow water. Second, scientific management of water, shallow water ground irrigation, proper drying The survival time of transplanting should be 3-4 cm in the field water layer, so that the field will form a relatively reasonable insulation and moisturizing environment, promote the emergence of new roots, and quickly return to green live trees. After walking and returning to the green, the seedlings enter the tillering stage and should be irrigated by shallow water. Generally, the water layer is maintained at 2-3 cm. When the rice tillers reach 80% of the number of tillers required for the expected yield, the field should be drained. Sundry has the effect of inhibiting soil nutrients first and then promoting them. It has a good effect on the control of rice populations, the promotion of vegetative growth from rice to reproductive growth, and the cultivation of large ear and multiple grains. Sun Tian generally grasps clay fields, low-level fields, and heavy fields. Sandy fields and thin fields are light in the sun. The sun usually spreads to small cracks in the field, the foot does not fall, the leaf color fades, and the leaves stand upright. This will control the production of invalid labor and increase resistance to lodging and resistance to pests and diseases. Third, pest and disease control The main diseases are leaf blight and sheath blight. The prevention and treatment of leafhoppers. In the initial stage of leaf blasting, use 75% of tricyclazole (Fengdeng) 30g or 40% of Fuji No.1 EC 100ml, add 40-50 kg of water evenly. Control of sheath blight. At the end of labor, when the incidence rate reaches more than 5%, 80 g of oxadiazole or 20 ml of benzoylzinc and 40-50 kg of water are sprayed per mu, and the middle and lower leaves of rice are sprayed.
