How to shorten the slow recovery period of rice? Practical methods shared
Spring is the time when all things revive, and this is also 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 it lasts too long, it can cause the rice to die, so how do you shorten the rice seedling recovery period? Let's take a look at the detailed introduction.
1. Strengthen patrol inspections
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, ensuring a full stand of seedlings.
2. Irrigation
After rice transplanting, irrigate 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, just maintain a shallow water layer of 2-3 cm, which can raise the soil temperature, promote new root growth, and get through the slow recovery period very quickly. In addition, when irrigating, because the water temperature is relatively low, you can lengthen the water channel and change the water inlet and supplementary water 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 as topdressing, which 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 seedling growth, which is unfavorable for later growth.
4. Weeding ⟧11⟧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 weeds should be removed 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, giving a good weeding effect.
