The latest ways to shorten the slow period of rice

When everything recovers in spring, the work of transplanting rice seedlings has begun, but it takes several days for rice to grow new roots, which is the slow seedling stage of rice. If the time is too long, it will lead to the death of rice, then what about shortening the slow seedling stage of rice? Let's take a look at the detailed introduction.

1. Strengthen inspection

After transplanting rice seedlings, the whole field should be inspected and inspected. Once the phenomenon of floating and falling seedlings is found, it should be dealt with in time, and the seedlings should be replanted or replanted to ensure that the seedlings are complete.

2. Irrigation

It is necessary to irrigate immediately after transplanting rice seedlings, and the water depth is about half of the seedling height, which is to reduce leaf transpiration and improve the balance of seedlings in water. After 2-3 days, keep the shallow water layer 2-3 cm, which can increase the ground temperature, promote the growth of new roots, and get through the slow period very quickly. In addition, in irrigation, because the water temperature is low, it can prolong the waterway, change the inlet and replenish water to increase the water temperature to facilitate the growth of seedlings.

3. Topdressing

After a week of transplanting, a small amount of chemical fertilizer can be applied, generally applying about 3-4 kg of urea per mu, which can promote the growth of new leaves, and attention should be paid to keeping the shallow water layer about 2-3 cm when topdressing. If the basal fertilizer has been applied before transplanting, it can not be applied, so as not to grow the seedlings, which is disadvantageous to the growth in the later stage.

4. Weeding

Sufficient occurrence in the field after transplanting, but also provide a suitable environment for the growth of weeds, they will compete with seedlings for water and fertilizer, so weeds should be weeded in time 5-7 days after transplanting. Generally, baa uses 500 grams of 50% EC mixed with sand, or 150 g of 96% EC mixed before the second leaf of barnyardgrass, the weeding effect is better.
