For a long time, some fruit farmers have not fully understood the nitrogen, phosphorus and potassium fertilizer requirements of peaches, pears, apples and other fruit trees (2:1:2), and often refer to the fertilizer habit of planting wheat on a one-sided basis, focusing on the use of phosphate fertilizer. Even some people use diammonium phosphate (usually nitrogen, phosphorus, potassium as 18:46:0), which is not suitable for direct use as a base fertilizer, and is applied to the tree in large quantities, resulting in a shortage of potassium in the soil, excess phosphorus, excessive The phosphorus element can not only be absorbed and utilized by fruit trees, but also has a certain antagonistic effect on nitrogen in the soil, resulting in disordered soil nutrient structure. At the same time, too much phosphorus will aggravate the soil compaction, causing the soil permeability to be destroyed, resulting in root rot and other soil-borne diseases and dry rot, blight, rot and other branches, yellow leaves, leaflets, The thin and weak trees that are not wilting often appear frequently, and some Taoyuan are even golden. In addition, some fruit farmers excessively apply ammonium bicarbonate or use unfermented and stalked straw and human and animal waste, which also aggravate the phenomenon of root burning, rooting and rotten roots to varying degrees.
In order to better solve the yellow leaf and lobular disease caused by the misunderstanding of fertilization, the author began this research from more than ten years ago. After repeated trials and tests, I finally succeeded in exploring the following quick-acting, non-recurring, economical and practical methods of treatment, such as the bottling method of the liquid bottle, the method of bottling the bottle, and the infusion of the trunk. The effect of the law is obvious, and there is no recurrence after the cure. The specific operation method is as follows:
Method 1: 1000 g of ferrous sulfate, 500 g of zinc sulfate, 500 g of fertilized fertilizer, 100 g of potassium dihydrogen phosphate, borax and calcium nitrate, 100 ml of peracetic acid, and a tree of 15 kg of water is mixed. When pouring, firstly excavate 30 holes in the canopy projection range of each tree, the depth is 5-6 cm, then pour the holes, and cover the soil after water seepage.
Method 2: Beijing Jinbilai brand with high potassium, nitrogen, phosphorus, activator, rooting agent and various trace elements such as iron, zinc, molybdenum, boron, calcium, etc. 40% gold power potassium treasure 1250 ml +21 100 ml of peracetic acid, 15 kg of water, poured a tree, the same method as above.
Method 3: Use 55% Eurasia brand rich in high potassium, nitrogen, phosphorus, fungicide, regulator and iron, zinc, manganese, calcium, copper (chelating state), magnesium, boron, sulfur and other medium and trace elements Multi-functional water-soluble fertilizer 500g + 21% peracetic acid 100ml, 15kg of water, poured a tree, the same method as above.
