When is the best time to fertilize rice? A detailed explanation of key fertilization techniques

We all know that rice is the cooked rice we eat every day. To grow rice well, the variety certainly matters a great deal, but field management matters even more, that is, small matters like fertilizing. Although fertilizing seems like a small matter, it is actually quite particular. Today let us learn together about the timing of rice fertilization and the methods and approaches for fertilizing rice.

Fertilization timing

Before transplanting the seedlings, we apply fertilizer to the paddy field once. This time it is basically farmyard manure, that is, the usual livestock manure. This is the base fertilizer, and its purpose is to maintain soil fertility. The second fertilization is about ten days or so after transplanting. This time the fertilizer applied is a mixture of urea and compound fertilizer from chemical fertilizers, scattered into the paddy field. The purpose is to prepare for tillering, so that the tillering time can be earlier and there can be more tillers, so the yield will be much higher. The third fertilization must wait until it grows ear buds. At this time the nutrients required are relatively greater, so the amount of fertilizer applied this time should be increased, but it must be in the appropriate amount. Promote the development and growth of the ear buds. The last fertilization is when the rice ears have all grown out and are fully developed. At this time the main purpose of fertilizing is to make the rice grains fuller and prevent empty ears from appearing.

Fertilization techniques

Fertilization method: When fertilizing, pay attention to the method. First, when fertilizing, pay attention to the growth condition of the rice, and judge whether fertilization is needed according to different growth conditions. If fertilizer is applied too early, it will cause excessive growth and an increase in useless rice seedlings, but if fertilizer is applied too late, it is easy to cause many diseases such as malnutrition, and at the same time the rice may fall over because it cannot adapt to this level of fertility for a while. Second, fertilization should pay attention to the dosage, which requires us to fertilize according to the fertility of the paddy field and the growth of the rice. Usually one mu should use eight kilograms of compound fertilizer or six kilograms of urea. Finally, when fertilizing, try to use the spraying method, and at the same time add a little washing powder to the fertilizer solution, so that the fertility can be prevented from evaporating.

Fertilizer types: The types of fertilizers used for rice are actually not many, and they are all targeted fertilizers applied according to different periods of growth and development. Generally they are compound fertilizer, urea, silicon fertilizer, biological bacterial fertilizer, potassium fertilizer, organic fertilizer, phosphate fertilizer and nitrogen fertilizer. But the use of nitrogen fertilizer must be in the appropriate amount, otherwise dead seedlings may appear, and at the same time the taste of the cooked rice will also be very poor.

Key points of fertilization: When fertilizing, try to adopt the method of side-deep fertilization. The first benefit of this kind of fertilization is that it can improve the utilization rate of fertilizer and reduce the amount of fertilizer used. The second is that it can promote the growth and development of rice. The third is that it can reduce the disease rate of rice, reduce environmental pollution and increase yield. When adopting side-deep fertilization, be sure to pay attention to the spacing between rice plants, the fertilization ratio and the paddy field soil and other issues.

Planting rice is actually a technical job. Without this technique, it is really hard to grow rice well. The above is what Qinnong Network introduces to everyone about the timing of rice fertilization and the problems and methods to pay attention to in fertilization.
