Apple root dressing, also known as foliar spray fertilizer, is a fertilization method in which the fertilizer is formulated into a certain concentration of aqueous solution and sprayed directly onto apple branches, leaves, and fruits. In actual production, it has been adopted by many fruit growers. Then, compared with soil fertilization, what are the advantages of root-spraying fertilizer? The reporter interviewed Professor Lei Zongzhong of the Yangling Vocational and Technical College. He said that the advantages of foliar spray fertilizer are compared with the general soil fertilization in five aspects:
The role of rapid development Lei Zongzhong said that using the root-spraying fertilizer, the absorption rate of urea and phosphate fertilizer after spraying can reach 50% and 20% in 8 hours and 88% and 50% in 6 days. In the same period, the phosphorus absorption rate in soil is only It is 6% to 9%.
In addition to having a more uniform role in supplying fertilizer, Lei Zongzhong told reporters that the method of applying roots and fertilizing can directly obtain nutrients from branches, leaves, and fruits in various parts of the canopy, and is not controlled by the nutrient distribution center of the tree. Evenly and thoughtfully, it can timely adjust the contradiction between supply and demand of nutrients, which is of great benefit to tree growth.
Fertilizer utilization is high. In addition, the advantage of foliar spray fertilizer is that it is not limited by soil conditions. It can avoid the loss of fertilizer in the soil, fixation, biological utilization or other factors of antagonism. Fertilizer can be directly absorbed by leaves, branches and fruits. Reduce losses and improve fertilizer utilization.
Enhanced photosynthetic efficiency data showed that after apple leaves were sprayed with superphosphate extract or potassium dihydrogen phosphate, photosynthetic intensity could be increased by 0.5 to 1.0 times or more, and leaf respiration and enzyme activity could also be improved, root nutrition could be improved, and Root development.
Save fertilizer and labor Because the concentration of foliar spray fertilizer is very low, usually a few thousandths, the amount of fertilizer used is very small. When spray fertilizer is applied, it can be combined with orchard spraying and it is not necessary to spray it separately, which has the effect of economical fertilizer application.
Quick-frozen sweet corn is a way to preserve corn, mainly by refrigerating it to protect the rich nutrition, sweetness, freshness and crispness of corn. Quick-frozen Sweet Corn Kernels contain a large amount of vitamin E, which has the functions of promoting cell division, delaying cell aging, lowering serum cholesterol, preventing skin lesions, and reducing the symptoms of arteriosclerosis and brain function decline. Vitamin A in fresh corn also has auxiliary effects on preventing and treating common dry eye, bronchitis, dry skin and nerve paralysis in middle-aged and elderly people. Lysine rich in fresh corn (very little in dry corn) is an essential nutrient for the human body. Studies have found that eating more quick-frozen sweet Corn Kernels can also inhibit the side effects of cancer drugs on the human body.
