Strengthen rice seedling management in May
Strengthening water management After rice transplanting, in order to make the seedlings turn green quickly, the seedlings that have just been moved soon, the new roots are not long, and the water absorption and fertilizer absorption ability is weak. It is necessary to promote the rooting and protecting seedlings through reasonable water management. After rice transplanting, the water layer should be kept at 2~3 cm, which is conducive to survival. The returning period is generally 5-8 days.
Timely after the application of tillering fertilizer, 5~7 days after the planting, the sub-fertilizer is applied, and the urea is mainly used for urea. 250 g of zinc-zinc fertilizer is added to promote the rapid growth of early rice, and the high-yield seedlings are quickly set up, and this year's early rice has a good harvest. .
For the prevention of pests and diseases, for early planting and direct seeding, in the middle of May, the rate of the sheath is up to 8% (or the rate of the sheath is up to 3%) for whole field control, and the field below 8% can pick up the sheath. After a serious field, the drug will be used again after 7 days; late planting should be carried out in the second half of May.
Controlling aphid agents: avermectin, triazophos, profenofos, methoxyfenozide, avidin and other agents.
Control of spider mites: tricyclazole, indole, pyraclostrobin and other agents.
In addition, when the farmers are fighting drugs, it is best to keep the diving layer in the field. If it rains within 6 hours after the medicine, it is necessary to make up the beating, and add some foliar fertilizer to the field where the seedling growth is poor. There is a lot of rain in May, and a pack of silicone can be added per barrel of water when applying.
