Pay attention to transplanting corn seedlings. How can the survival rate of transplantation be high?

At present, many rice planting areas have entered the busy time of rice transplanting. In order to ensure the growth, early rooting and early tillering of rice, cultivate strong seedlings and reduce pests and diseases, the following points should be paid attention to when planting rice:

First of all, before transplantation

1. Raise seedlings in advance: Before transplanting rice, it must be carried out in advance, so that the seedlings can adapt to the natural environment as soon as possible, control the temperature and humidity in the shed, and avoid the seedlings from growing.

Transplanting to these points, returning seedlings, tilting early and high yield!

2. Water control seedlings: 3-3.5 days before seedling emergence or 3-4 days after transplanting, the water spring should be controlled in time so that the seedlings can be replenished in water. After transplanting, the root system quickly absorbs water, fertilizer and nutrition, realizing quick recovery, quick rooting, early greening and early growth.

3, transplanting time: the transplanting time should be accurate, generally transplanting in 3-4 leaves, to ensure that it is not too late.

4. Transplanting depth: When transplanting rice, the manual transplanting is about 1.5cm, and the mechanical transplanting is about 2cm. The end of the transfer leads to scattered seedlings, seedlings, floating seedlings and zeale. At the same time, the ear is very small, and it does not resist this pair; Transplanting will cause greening, tillering and late stage.

Second, the transplant prevention measures

1, fat transfer: the night before planting, the seedbed can be used according to 150g diamine/average fertilizer, which can effectively improve the resistance of seedlings, thus transferring seedlings. Roots, early tillering.

2. Transplanting with drugs: 3 days before transplanting, it can be used according to the amount of water of 25-30 rrpopyrone or pyridine+15kg per mu of seedbed. The occurrence of flies and mud bugs, this method is better for people who are sick, deposited and fashionable.

3, containing bacteria, when planting seedlings, a proper amount of high quality will be applied. On the one hand, it can reduce the influence of low temperature on seedlings. On the other hand, it can promote the root system of seedlings to recover as soon as possible and promote the generation of new roots. If the development is announced as soon as possible, new seedlings can grow, the growth effect can be cultivated, the anti-counterfeiting effect can be improved, and seedling cultivation can be promoted in advance.
