The latest course on fertilization time and techniques for Rice

We all know that rice is the rice we usually eat. if we want rice to grow well, it does have a lot to do with the variety of rice, but it is more about field management, that is, such little things as fertilization. Despite the fact that fertilization is a small matter, it is very fastidious. Today, let's learn the time of fertilization for rice and the ways and methods to fertilize rice.

Fertilization time

We will fertilize the rice field before transplanting seedlings, this time it is basically farm manure, that is, the droppings of livestock, this time is the base fertilizer, in order to maintain soil fertility. The second fertilization is about ten days after transplanting. This time, urea from chemical fertilizer and compound fertilizer are mixed and sprinkled into the rice fields, in order to prepare for tillering, so that the time of tillering can be advanced, and there are more tillers, so the yield will be much higher. The third fertilization will wait until it grows out of the spike, and more nutrients are needed at this time, so the amount of fertilizer should be increased this time, but in an appropriate amount to promote the development and growth of the spike, and the last time the fertilizer is to wait for the rice ear to grow and fully develop. at this time, the main purpose of fertilization is to make the rice fuller and avoid the occurrence of empty ears.

Fertilization technology

Fertilization methods: pay attention to the methods when applying fertilizer, first of all, pay attention to the growth of rice, according to different growth conditions to judge whether it is necessary to apply fertilizer. If fertilizing too early will cause too fast growth, useless rice seedlings will increase, but fertilization too late will easily lead to malnutrition and many other diseases, at the same time, rice may not be able to adapt to this degree of fertility and seedling fall. Secondly, we should pay attention to the amount of fertilization, which requires us to fertilize according to the fertility of the paddy field and the growth of rice, usually using eight kilograms of compound fertilizer or six kilograms of urea per mu. Finally, try to spray fertilizer, while adding a little washing powder to the fertilizer solution, so as to prevent the fertility from evaporating.

Types of fertilization: there are not many kinds of fertilizers used in rice, and they are targeted fertilizers according to different periods of growth and development. Generally, it is compound fertilizer, urea, silicon fertilizer, biological bacterial fertilizer, potash fertilizer, organic fertilizer, phosphate fertilizer and nitrogen fertilizer. But the use of nitrogen fertilizer must be appropriate, otherwise there may be dead seedlings, at the same time, the taste of the rice is also very bad.

Key points of fertilization: try to adopt the method of lateral deep fertilization when fertilizing. the first benefit of fertilization is that it can improve the utilization rate of fertilizer and reduce the amount of fertilizer. The second is that it can promote the growth and development of rice. The third is that it can reduce the prevalence rate of rice, reduce environmental pollution and increase yield. When using lateral deep fertilization, we must pay attention to the distance between rice, the proportion of fertilization and the soil of paddy field.

As a matter of fact, growing rice is also a technical activity, and it is really not good to grow rice without this technology. the above are the problems and methods that should be paid attention to by the pro-agricultural network about the time and methods of fertilizing rice.
