China is a big country for rice cultivation. A long time ago, we were still worried about how to eat a full meal. Later, Yuan Longping appeared. He researched hybrid rice and greatly increased the yield of rice. Now we have been passing some other methods. I want to increase the output of rice to a higher level. In a few days, we will learn how to apply fertilizer to make rice high-yield.
1. The base fertilizer is the basis of rice growth, so the suitability of the base fertilizer must be sufficient. The base fertilizer has a large proportion in the growth process of rice. Usually we usually sprinkle some farmyard manure and ammonia fertilizer. In fact, the best way to use the base fertilizer is to use a mixture of fermented fertilizer and organic fertilizer. At the same time, a small amount of chemical fertilizer is applied. The chemical fertilizer is mainly phosphate fertilizer and potassium fertilizer. Of course, a little nitrogen fertilizer can be added. However, it is recommended that you do not use too much fertilizer such as nitrogen fertilizer in the early stage of rice growth. When applying the base fertilizer, try to apply it as deep as possible to maintain fertility.
2. Fertilizer and manure are generally fertilized about a week after transplanting. The amount of fertilization should not be too strong, because rice tillers only need a proper amount of fertility. If the force is too strong, this will cause many ineffective tillers in rice. This will not only increase rice yield but also reduce yield. The best fertilizer for rice tillering is quick-acting organic fertilizer plus a little urea and livestock manure. Manure is generally carried out in batches, in order to prevent excessive force, so generally do not apply a little at a time, if the rice in the field is slower, then it will be pursued once again.
3, panicle fertilizer ear fertilizer is mainly to promote flowers and flowers, the number of ears probably determines the rice yield, so panicle fertilizer is a relatively important time for rice fertilization. When the rice is about to bear the ear, it is necessary to prepare it. Generally, it is mainly applied with potassium fertilizer. Secondly, it can also be mixed with urea to promote growth. After the earing, there will be a period of time to dry the water in the field and then re-pump the water, which will reduce the probability of lodging. After the pumping is completed, a top dressing is carried out, mainly nitrogen fertilizer and potassium fertilizer.
4, grain fertilizer and grain fertilizer is to be implemented after the rice ears are all out. At this time, it is mainly to make the rice granules fuller and reduce the flat grains on the ear. Generally speaking, phosphate fertilizer and potassium fertilizer are the best to promote the fullness of the grains. Fertilizer, but also a little bit of urea, it can be said that urea is throughout the entire fertilization period. When applying the grain fertilizer, be careful not to use too much. Otherwise, it will fall into the paddy field and fall into the rice field. When the loss is heavy, it will not be worth the loss. (Source: pro-farm network)
