Matters needing attention

1. Disinfect the seeds.

Seed drying and seed selection are carried out before chemical treatment to enhance seed germination potential and improve seed germination rate. Soak the seeds with 25% prochloraz for disinfection: soak the seeds 12 hours with clear water first, and then soak them with 3000-4000 times of prochloraz solution, that is, a stick 1 ml of 25% prochloraz mixed with 6-8 kilograms of water can soak about 6 kilograms of rice seeds. After soaking the seeds for 24 hours, take out the rice seeds and sow or germinate directly without cleaning.

We should ensure good germination and sowing.

Do not germinate soaked and disinfected seeds, or use heat preservation to accelerate germination until the chest is white, and grasp the favorable weather with warm head and cold tail to sow in time. Coated seeds can be sown directly without any treatment.

We should manage the rice fields well.

Don't use urea when tidying up the rice fields. Appropriate amount of high-quality seedling strengthening agent or a small amount of compound fertilizer should be used, and the film should be tightly covered for heat preservation after sowing. If the weather is sunny and hot after full sowing, attention should be paid to uncovering the film in time to prevent the seedlings from burning in the film at high temperature, and covering the film again in time to keep warm at low temperature.
