Fertilization methods for High yield of Rice

China is a big rice-growing country. A long time ago, we were still worried about how to have a full mouthful. Later, Yuan Longping appeared. He developed hybrid rice, which greatly increased the yield of rice. But now we have been through some other ways to make the output of rice, please climb another tall building. In a few days, let's learn how to apply fertilizer to make high yield of rice.

1. Base fertilizer

Base fertilizer is the basis of rice growth, so the suitable application of base fertilizer must be sufficient, base fertilizer accounts for a large proportion in the process of rice growth, usually we usually sprinkle some farm fertilizer and ammonia fertilizer. In fact, the best way to use base fertilizer is a mixture of rotten fertilizer and organic fertilizer, while applying a small amount of chemical fertilizer, mainly phosphate fertilizer and potash fertilizer, of course, you can also add a little nitrogen fertilizer. However, it is recommended that in the early stage of rice growth, try not to use too much nitrogen fertilizer and other chemical fertilizer, apply base fertilizer as deep as possible, so as to maintain fertility.

2. Tillering fertilizer

Tillering fertilizer usually begins to be fertilized about a week after transplanting rice seedlings, and the amount of fertilization this time should not be too fierce, because rice tillering only needs an appropriate amount of fertility, and if it is applied too hard, it will produce a lot of invalid tillers, which will not only not increase the yield of rice, but also reduce the yield of rice. The best fertilizer for rice at tillering stage is available organic fertilizer plus a little urea and livestock manure. Tillering fertilizer is generally carried out in batches in order to prevent excessive force, so it is generally applied less at a time, and if the tillering of rice in the field is relatively slow, it is good to apply it again.

3. Panicle fertilizer

Panicle fertilizer is mainly to promote and protect flowers, the number of panicles probably determines the yield of rice, so panicle fertilizer is a more important time for rice fertilization. When the rice is about to bear ears, it is necessary to be prepared, usually mainly by applying potash fertilizer, and secondly, you can also mix some urea to promote growth. After heading, the water in the field will be dried and then re-pumped for a period of time, which will reduce the probability of lodging and top dressing after pumping, mainly nitrogen and potash fertilizer.

4. Grain fertilizer

Grain fertilizer is not implemented until all the rice ears are full, mainly in order to make the rice grains fuller and reduce the flat grains on the panicles. Generally speaking, phosphate and potash fertilizers are the best fertilizers to promote grain fullness, and should also be mixed with a little urea, which can be said to run through the whole fertilization period. When applying grain fertilizer, we should be careful not to use too much, or the rice will lodge in the early rice field, and the loss will outweigh the gain.

In fact, fertilization is one of the important conditions for high yield of rice, and the method of fertilization must be correct, not blindly. The above is the editor today to tell you about a method of rice fertilization, more details, all in our pro-agriculture network.
