It is also a great advantage of foliar fertilizer. According to the test, the 1%~2% urea aqueous solution can be sprayed on the foliar surface, and it can absorb 1/3 after 24 hours. Spray 2% concentration of superphosphate extract. After 5 minutes, it can be transferred to all parts of the plant. This is especially useful in the plant seedling stage. Generally, the root system is underdeveloped, the absorption capacity is weak, and the phenomenon of seedling yellow and seedling is prone to occur, and the effect of foliar fertilization is more obvious.
Significantly increasing the utilization of fertilizers is generally considered to be more important for foliar fertilizers. At present, the average utilization rate of fertilizer in China is less than 30%, and a large amount of fertilizer is not effectively utilized. Moreover, excessive fertilizer also enters the soil to cause soil compaction and enter the water pollution environment. The foliar fertilizer is directly sprayed on the leaf surface, and the utilization rate is greatly improved. Foliar fertilizer can be sprayed with pesticides, which greatly reduces the labor intensity of using foliar fertilizer.
Foliage fertilizer has become a consensus of more and more people, but at the same time, people from the Ministry of Agriculture also pointed out that since foliar fertilizer is sprayed on the surface of leaves during crop growth, it can only temporarily supplement nutrients. . For a large number of elemental fertilizers such as nitrogen, phosphorus and potassium, the crop needs a large amount, and simple foliar fertilizer is not enough, and soil fertilization is also needed.
Foliar fertilizer is a fertilizer applied to the foliage of crops during crop growth. Generally can be divided into a large number of elemental foliar fertilizer, trace element foliar fertilizer, humic acid foliar fertilizer and amino acid foliar fertilizer. In recent years, foliar fertilizer has been favored by more and more people.
