What are the precautions for fertilizing rice? Explained clearly in one article

Rice is essential in our daily lives, and its planting area is also one of the largest among grain crops in our country. When growing rice, fertilization work is very important. Fertilization can ensure that the nutrients needed for rice growth are met and increase rice yield. However, there are also many points we need to pay attention to when fertilizing. Below, the editor brings you the precautions for fertilizing rice. Let's take a look!

1. Control nitrogen fertilizer

Nitrogen fertilizer can effectively promote the growth of rice and enhance its growth capacity. However, when applying nitrogen fertilizer, we must also pay attention to controlling the amount used. Although nitrogen fertilizer is good, it must never be used in excess, otherwise it can easily cause excessive vegetative growth of rice. This affects the rice turning green, triggers various diseases and pests, causes undesirable phenomena such as lodging and empty grains, reduces the seed-setting rate of rice, and leads to decreased yield. When applying nitrogen fertilizer, it is mainly used as topdressing, usually applied about twice within half a month after transplanting. The amount used should be controlled within 15 kg.

2. Application of farmyard manure

Farmyard manure has a relatively comprehensive content of nutrient elements. Reasonable application of farmyard manure can effectively improve the soil, increase soil permeability, enhance water absorption capacity, and promote rice growth. However, when applying farmyard manure, we must pay attention to ensuring that the farmyard manure is fully decomposed. The heat generated by the fermentation of undecomposed farmyard manure can also burn the rice, causing fertilizer damage to the rice and affecting the normal growth of rice. Farmyard manure is mainly applied as base fertilizer, and a sufficient amount must be ensured so that it can meet the nutrients needed for the growth of rice seedlings.

3. Phosphate and potassium fertilizers

Phosphate and potassium fertilizers are also very important for rice growth. They can not only increase the growth rate of rice, but also enhance the disease resistance of rice and reduce the incidence of diseases and pests. They promote photosynthesis in leaves, prolong the functional period of leaves, ensure full rice grains, and increase yield. The application of phosphate and potassium fertilizers is usually combined with farmyard manure as base fertilizer. However, appropriate topdressing in the later stage of rice growth is also beneficial for promoting grain filling and plumpness. However, attention should also be paid to the amount used, and partial application should be avoided to prevent fertilizer damage, deficiency of other nutrient elements in rice, and effects on its normal growth.

4. Trace element fertilizers

Rice also has a certain demand for trace elements during growth. For example, nutrients such as zinc and silicon can effectively promote the growth of rice roots, improve the stress resistance of rice, and reduce lodging. They can also prevent premature aging of rice, promote flowering and seed setting, and are of great help in increasing yield. There are many types of trace elements, which provide different benefits to rice growth. Therefore, during the planting process, we should appropriately apply trace element fertilizers in the form of foliar fertilizer to meet the rice's requirements for trace elements.

The above is a brief introduction to the precautions for fertilizing rice. We must attach importance to the fertilization work for rice, ensure normal growth of rice, increase yield, and expand planting benefits. That is all for today's introduction.
