The latest matters needing attention in rice fertilization

Rice is indispensable in our life, and its planting area is also one of the largest food crops in our country. Fertilization is very important when planting rice. Fertilization can ensure to meet the nutrition needed for rice growth and improve the yield of rice. However, there are also many things that need our attention when fertilizing. The following editor brings you some matters needing attention on rice fertilization, let's have a look!

1. Control nitrogen fertilizer

Nitrogen fertilizer can effectively promote the growth of rice and enhance the growth ability of rice. But when we apply nitrogen fertilizer, we should also pay attention to control the amount of nitrogen fertilizer. Although nitrogen fertilizer is good, it must not be too much, otherwise it will easily lead to the overgrowth of rice. It affects rice turning green and causes all kinds of diseases and insect pests. There are some bad phenomena, such as lodging, empty chaff and so on, which reduce the seed setting rate of rice and reduce the yield. Nitrogen fertilizer is mainly topdressing, which is usually applied twice in half a month after transplanting. Its dosage should be controlled within 15 kg.

2. Application of farm manure

The content of nutrient elements in farm manure is more comprehensive. Reasonable application of farm manure can effectively improve soil, improve soil permeability, enhance water absorption capacity, and promote the growth of rice. However, when we apply farm manure, we should pay attention to ensuring that it is fully mature. The heat produced by the fermentation of immature farm manure and the burning of rice lead to fertilizer damage to rice and affect the normal growth of rice. Farm manure is mainly applied as a base fertilizer, and to ensure that the amount is sufficient to meet the nutrition needed for the growth of rice seedlings.

3. Phosphate and potassium fertilizer

Phosphorus and potassium fertilizer is also very important for the growth of rice. It can not only improve the growth rate of rice, but also enhance the disease resistance of rice and reduce the incidence of diseases and insect pests. Promote photosynthesis of leaves, improve the functional period of leaves, ensure the fullness of rice grains and increase the yield. The application of phosphorus and potassium fertilizer is usually combined with farm manure as base fertilizer. However, proper topdressing in the later stage of rice growth is also beneficial to promote grain filling and fruiting. However, we should also pay attention to its dosage, not partial application, to avoid fertilizer damage, rice lack of other nutrients, affecting its normal growth.

4. Trace element fertilizer

Rice also has a certain demand for trace elements in its growth. For example, zinc, silicon and other nutrients, zinc and silicon can effectively promote the growth of rice roots, improve the stress resistance of rice and reduce lodging. And it can also prevent the premature senescence of rice and promote flowering and fruiting, which is of great help to the increase of yield. There are many kinds of trace elements, which are helpful to the growth of rice. Therefore, in the process of planting, we should properly apply trace element fertilizer in the form of foliar fertilizer to meet the requirements of trace elements in rice.

The above is a brief introduction to the matters needing attention in rice fertilization. We must attach importance to the fertilization of rice to ensure the normal growth of rice, increase the yield and expand the planting efficiency. That's all for today's introduction.
