1. Immediately after transplanting, protect the seedlings and protect the water and return it to green, subjecting to the non-submerged seedlings, the seedling leaves shall prevail. When the seedling protection depth is 2 cm, the seedlings will be returned to green for 6 to 7 days, and when the seedling protection depth is 4 cm, the seedlings will return to green. The required number of days is 4 to 5 days. Under certain conditions, the plant height increased by 1 cm for every 2 cm increase in seedling depth, and the number of roots increased by about two. 2, early application of fertilizer, after inserting 3 to 5 days after the seedlings returned to green immediately after application of fertilizer, the amount of fertilizer is 30% of the total amount of nitrogen fertilizer, of which, 80% of the total amount of manure after inserting 4 to 5 days all fields, The other 20% (urea 1 kg/mu) 7 to 9 days after the field to look for Shi, which yellow which is weak, which promote fertilizer effect response in the 6 to 7 leaf stage (effective tiller Sheng Yu leaf position), promote seedling early delivery, Faster delivery, more delivery, less effective delivery. In order to extend the fertility period, ammonium sulfate and urea can be used in combination, 3 kg of ammonium sulfate instead of 1 kg of urea. 3, timely pest control, the occurrence period of the rice leaf miner is in the end of May to early June, after the transplanting insect pests in a timely manner to investigate the situation, found that when the leaf miner is harmful to the timely spraying control. The survey method is to select the seedlings that are 8 to 10 days after plugging in and approach the surface of the water and lay a tile on the surface of the water. Then gently pry the leaves by hand and find that the small particles in the middle of the blade are the larvae of the leafminer. Spray control.
