How to apply fertilizer in dry season
How to fertilize crops in the dry season? Since the summer of summer, there have been rare droughts in many areas of China. According to CCTV reports, only 13.14 million mu of crops in Henan have serious drought conditions. In order to reduce the damage caused by drought to crops, this paper introduces some droughts. How to fertilize crops in the season? In the dry season, due to lack of water, the absorption rate and utilization rate of fertilizers are greatly reduced. The following are matters needing attention:
In the dry season, the amount of fertilization should not be too large. If the amount of one-time fertilization is too large during drought, it will easily cause the fertilizer to be washed away when it encounters heavy rain after drought. This will not only cause economic losses to farmers, but also pollute the environment. Therefore, it should be combined with irrigation for fertilization.
When fertilizing in dry season, pay attention to the deep application of fertilizer in the case of drought, spread the fertilizer on the ground, and the fertilizer is volatile. Fertilizer should be applied as deep as possible, and the machine should be drenched with water to maintain fertilizer efficiency.
In the case of drought, the type of fertilization and the fertilizer need to pay extra attention, pay attention to the reasonable combination of fertilizer, especially potassium fertilizer, boron fertilizer. Because potassium ions can regulate the colloidal properties of protoplasts, so that water can smoothly enter the cells and strengthen the water holding capacity of the cells. Therefore, suitable potassium nutrition can enhance the water absorption capacity of crops, enhance drought resistance of crops, and improve soil water use efficiency. Need to pay attention to the appropriate supplement of boron fertilizer.
