Rice is a kind of herbaceous rice genus, which belongs to cereals. It is also the most important and longest food in rice genus. It is native to China and India. Rice was planted in the Yangtze River Valley in China 7,000 years ago. Regarding the problem of applying compound fertilizer to rice, why is it not recommended to apply compound fertilizer to rice? I believe that I will explain it below: Everyone knows that compound fertilizer contains more than two kinds of fertilizers, which saves a lot of troubles in the process of fertilizing farmers. It can be said that it is very convenient. Applying a fertilizer crop adds a variety of nutrients. But any fertilizer is not perfect, the nutrients of the compound fertilizer are fixed, and there is no way to move the proportion. However, the absorption of various elements of fertilizer during the growth of rice is not the same, the proportion is also much worse, especially the absorption of potassium fertilizer, the absorption ratio of three fertilizers of NPK is generally 2:1:3. And the fertilizer response time of rice is relatively slow. Therefore, the compound fertilizer with a relatively fixed composition cannot meet the demand for fertilizer. Therefore, it is not recommended that growers use compound fertilizer. If you really want to use compound fertilizer, you can consider using rice-specific compound fertilizer. Rice-specific compound fertilizer is mainly a compound fertilizer produced according to the demand characteristics of rice for fertilizer. Generally, the special compound fertilizer for rice is mainly used as the base fertilizer for rice. According to the soil fertility, the amount of land per acre is about 25 kg. When using the common formula compound fertilizer, it is best to combine the soil testing formula for fertilization. In addition, it is necessary to consider the local soil fertilizer condition and rice yield and other factors for comprehensive fertilization. In addition, the compound fertilizer is generally used as a base fertilizer, and it is not recommended to use it as a top dressing, otherwise it is a waste of fertilizer. It is best to choose potassium chloride compound fertilizer and NPK compound fertilizer. It is not recommended to use diamine phosphate. The use time of general compound fertilizers Rice is applied to rice fields before deep-turning the land. Generally, the fertilization amount per mu is about 15 kg. Finally, the most recommended is to use the three major fertilizers of nitrogen, phosphorus and potassium to mix and fertilize. It is necessary to carry out reasonable fertilization according to local conditions, and the soil conditions in each area are different, so it is impossible to completely copy the fertilization strategies in other areas. First of all, the base fertilizer must be applied, and the combination of organic fertilizer and chemical fertilizer is better. Generally, about 40% of available nitrogen fertilizer, all phosphate fertilizer and 60% potassium fertilizer are used as base fertilizer. Another 30% of the nitrogen fertilizer is used as a manure. The last 30% of the nitrogen fertilizer and 40% of the potash can be used as panicle fertilizer. Disclaimer: Some articles on this website are transferred from the Internet.
