At present, many farmers do not understand the technical standards and methods of using phosphate fertilizer, and the effect after application is not satisfactory. How to get out of this misunderstanding?
î—¥
Misunderstanding 1: The more bubbles, the better. Put the sour fertilizer and ammonium bicarbonate in the barrel, add the pig manure water or water, like the boiling of the pot, the free acid content is too high, the fertilizer efficiency is low, and the microbial activity in the soil will be inhibited after application. Burning the roots of crops, causing the seeds to not germinate and so on. On the contrary, no foaming is insufficient in the amount of sulfuric acid, the reaction is incomplete, and the content of the active ingredient is low. Generally, the free acid content of superphosphate should not exceed 5.5%.
î—¥
Myth 2: The more expensive the price, the better. Some unscrupulous traders deliberately opened the price of phosphate fertilizer from different manufacturers, boasting that the higher the price, the better the quality. When purchasing, you should carefully select a slightly sour taste, grayish white powder, feel cool and no trace of water by hand, and be sampled and tested by the relevant departments to determine the quality of phosphate fertilizer.
î—¥
Misunderstanding 3: More phosphorus fertilizer is better. Many people are accustomed to apply a little more phosphate fertilizer, which is considered to have no effect on crop growth and yield. In fact, the application of too much phosphate fertilizer will destroy the nutritional balance of the crop, make the plant respiration too strong, the accumulation of dry matter is consumed, the plant growth and development is poor, resulting in decreased yield, reducing the effectiveness of soil zinc, and inducing crop deficiency. . If the amount of rice is too much, it will also affect the absorption of silicon by rice.
