A Detailed Guide to the Latest Rice Fertilization Precautions
Rice is essential in our 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, as fertilization can ensure 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 rice fertilization. Let's take a look together!
1. Control nitrogen fertilizer
Nitrogen fertilizer can effectively promote the growth of rice and enhance its growth capacity. But 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 in rice. This affects the greening of rice and triggers various pests and diseases. It can lead to poor phenomena such as lodging and empty grains, reduce the seed-setting rate of rice, and cause yield decline. 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 burn the rice, causing fertilizer damage to the rice and affecting its normal growth. Farmyard manure is mainly applied as a base fertilizer, and sufficient amount must be ensured to meet the nutrients needed for the growth of rice seedlings.
3. Phosphate and potassium fertilizer
Phosphate and potassium fertilizer is also very important for rice growth. It can not only increase the growth rate of rice, but also enhance the disease resistance of rice and reduce the incidence of pests and diseases. It promotes photosynthesis in leaves, prolongs the functional period of leaves, ensures full grains, and increases yield. The application of phosphate and potassium fertilizer is usually combined with farmyard manure as a base fertilizer. However, appropriate topdressing in the later stage of rice growth is also beneficial for promoting grain filling and seed setting. But attention should also be paid to the amount used, and it should not be applied in a one-sided way, so as to avoid fertilizer damage and a lack of other nutrient elements in rice, which would affect its normal growth.
4. Trace element fertilizer
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, and they provide different benefits to rice growth. Therefore, during the planting process, we should appropriately apply trace element fertilizer in the form of foliar fertilizer to meet the trace element requirements of rice.
The above is a brief introduction to the precautions for rice fertilization. We must attach importance to rice fertilization work, ensure normal rice growth, increase yield, and expand planting benefits. That is all for today's introduction.
