Skillfully applying phosphate fertilizer to resist drought and increase income

Last Updated: 2024/11/22, The absorption of phosphorus is the fastest in the seedling stage, and the critical period of phosphorus nutrition is in the seedling stage. if the lack of phosphorus in the seedling stage, it will affect the later growth of crops. In our province, the air temperature is low in spring, the activity of soil microorganisms is weak, the release of soil available phosphorus is low, the soil temperature is low, and the ability of root system to absorb nutrients is weak, so it is difficult to meet the needs of the critical period of crop phosphorus nutrition. ...

The available phosphorus in soil generally can not meet the needs of high yield of rice. Applying phosphate fertilizer to improve the available phosphorus in soil is an important method in agricultural production. The annual application of phosphate fertilizer to rice farmers in our province is generally base fertilizer (base fertilizer) per hectare. One application of diammonium phosphate fertilizer is 100Lv 150kg, at least 70Mel 80kg. When water rake is applied, the contact area of fertilizer is large, and phosphate fertilizer can not be moved and spread after being applied to the field, and rice roots cannot be absorbed and utilized until they are extended. At present, the utilization rate of chemical fertilizer for rice in cold regions is roughly 30% of nitrogen fertilizer, 10% of phosphate fertilizer and 40% of potash fertilizer. At present, most of the seedlings are raised in plates, and the root plates are also tight. when transporting seedlings, as long as the seedling trays are rolled up and transported directly to the ground, they will be installed with a transplanter, and the nutritious soil and fertilizers will be planted directly into the field with the seedlings. In the past, the use of single phosphate fertilizer even increased production. Now the seedbed is applied with phosphate fertilizer plus phosphorus bacteria fertilizer, 250 grams per square meter of seedbed. According to 120 square meters of seedlings per hectare, only 2750 kilograms of diammonium phosphate fertilizer is needed, plus 30 kilograms of phosphate bacterial fertilizer is mixed and sprinkled on the seedling bed 3 days before seedling raising, and then sprayed with water to make the fertile bacteria stick tightly around the seedling rhizosphere, and Honda will no longer apply phosphate fertilizer. At present, the price of phosphate fertilizer is soaring, and this technology can greatly save phosphate fertilizer and reduce production costs.
