How to Fertilize Rice for High Yield? A Detailed Guide to the Latest Methods

China is a major rice-growing country. Long ago, we were still worried about how to get a full meal, and then Yuan Longping came along and developed hybrid rice, which greatly increased rice yields. Today we have been trying through various other methods to push rice yields to an even higher level. In this article, let us learn how to fertilize rice so that it can achieve high yields.

1. Base fertilizer

Base fertilizer is the foundation of rice growth, so when applying base fertilizer it must be sufficient; base fertilizer accounts for a very large proportion of the rice growing process. Usually we simply spread some farmyard manure and ammonia fertilizer. In fact, the best way to use base fertilizer is a mixture of decomposed manure and organic fertilizer, together with a small amount of chemical fertilizer; the chemical fertilizer is mainly phosphate fertilizer and potassium fertilizer, and of course a little nitrogen fertilizer can also be added. However, it is recommended to try not to use too much nitrogen fertilizer and similar chemical fertilizers in the early stage of rice growth, and when applying base fertilizer, apply it as deep as possible so that fertility can be maintained.

2. Tillering fertilizer

Tillering fertilizer is generally applied starting about one week after transplanting. The amount applied this time must not be too aggressive, because rice tillering only needs a moderate amount of fertility. If it is too aggressive, it will cause the rice to produce many ineffective tillers, which will not only fail to increase rice yield but will also reduce it. The best fertilizer for the rice tillering stage is quick-acting organic fertilizer plus a little urea and livestock manure. Tillering fertilizer generally needs to be applied in batches, precisely to prevent applying too much at once, so generally apply a little less each time, and if the rice in the field is tillering relatively slowly, just apply one more top dressing.

3. Ear fertilizer

Ear fertilizer is mainly for promoting flowering and preserving flowers. The number of ears roughly determines the rice yield, so ear fertilizer is a relatively important time in rice fertilization. When the rice is about to form ears, preparations should be made. Generally, potassium fertilizer is mainly applied, and secondly a little urea can be mixed in to promote growth. After the ears form, there will be a period when the field water needs to be dried out and then pumped back in, which reduces the probability of lodging. After pumping the water back in, apply one more top dressing, mainly nitrogen fertilizer and potassium fertilizer.

4. Grain fertilizer

Grain fertilizer should only be applied after all the rice ears have emerged. At this time it is mainly to make the rice grains fuller and reduce flat grains on the ears. Generally speaking, phosphate fertilizer and potassium fertilizer are the best fertilizers for promoting full grains, and a little urea should also be mixed in; it can be said that urea runs through the entire fertilization period. When applying grain fertilizer, be careful not to use too much, otherwise it will cause lodging of the rice in the field, and then the losses will be heavy, and the gain will not be worth the loss.

To achieve high rice yields, fertilization is actually one of the important conditions, and the fertilization method must be correct; do not fertilize blindly. The above is the method for rice fertilization that the editor wants to tell everyone about today. For more details, stay with us at Qinnong Network.
