How to shorten the slow recovery period of rice? A detailed explanation of the latest methods

Spring is the period when all things revive, and it is also the time when rice transplanting work has begun, but after rice transplanting it takes several days to grow new roots, which is the rice seedling recovery period. If the time is too long, it will cause the rice to die, so how can the slow recovery period of rice be shortened? Let's take a look at the detailed introduction.

1. Strengthen patrol inspection

After rice transplanting, the entire field should be checked and patrolled. Once floating seedlings or fallen seedlings are found, they should be dealt with promptly by replanting or filling in gaps to ensure a full stand of seedlings.

2. Irrigation

After rice transplanting, irrigation should be carried out immediately, with the water depth at about half the height of the seedlings. This is to reduce leaf transpiration and also improve the stability of the seedlings in the water. After 2-3 days, keeping a shallow water layer of 2-3 cm is sufficient. This can raise the ground temperature, promote new root growth, and pass through the slow recovery period very quickly. In addition, when irrigating, because the water temperature is relatively low, the water channel can be extended, and the water inlet can be changed and water supplemented to increase the water temperature, so as to benefit seedling growth.

3. Topdressing

One week after transplanting, a small amount of chemical fertilizer can be applied. Generally, about 3-4 kg of urea per mu can promote new leaf growth. When topdressing, be careful to maintain a shallow water layer of about 2-3 cm. If base fertilizer has already been applied before transplanting, it may be omitted to avoid excessive vegetative growth of the seedlings, which is unfavorable for later growth.

4. Weeding

After transplanting, the field has sufficient growth, which also provides a suitable environment for weed growth. They will compete with the seedlings for water and fertilizer, so weeding should be carried out promptly 5-7 days after transplanting. Generally, 500 g of 50% benthiocarb emulsifiable concentrate mixed with sand is broadcast, or 150 g of 96% molinate emulsifiable concentrate is applied before the second leaf of barnyardgrass. The weeding effect is relatively good.
