Embodiment Construction

[0011] A special anti-stripping liquid for walnut trees. The anti-stripping liquid comprises the following components in weight ratio: 5% polyvinyl alcohol, 4% methylthio-naphthalene acetic acid and 3% nitrogen, phosphorus and potassium, and the balance is water.

[0012] Take 50g of white solid powdered polyvinyl alcohol and add it to 1000g of water, raise the temperature to above 95°C, heat for about 40 minutes until the polyvinyl alcohol is completely dissolved in water, then let the solution stand at room temperature, and then add 40 methylthio naphthaleneacetic acid, 30g mixture of ammonium nitrate, superphosphate and potassium sulfate (ammonium nitrate, superphosphate and potassium sulfate are 12.24g, 8.24g and 9.52g respectively, and the ratio of nitrogen, phosphorus and potassium is 1:0.5:1), stir well, The anti-stripping liquid of the present invention is obtained, and the pH value of the solution is 5-7, which is weakly acidic.

[0013] The anti-stripping liquid is s...

Abstract

The invention discloses sprouting-preventing liquid special for walnut trees. The sprouting-preventing liquid is prepared from, by weight, 3-8% of polyvinyl alcohol, 3-5% of sulfur A.naphthalene acetic acid, 2-4% of nitrogen phosphorus and potassium, and the balance water; white solid powder-like polyvinyl alcohol is taken and added into water, the temperature is raised to 95 DEG C or above until the polyvinyl alcohol is completely dissolved in the water, then, the solution stands to the room temperature, the sulfur A.naphthalene acetic acid, ammonium nitrate, superphosphate and potassium nitrate are added into the solution, the mixture is stirred to be uniform, the sprouting-preventing liquid is obtained, the pH value of the solution is 5-7, and the sprouting-preventing liquid is faintly acid. The sprouting-preventing liquid special for the walnut trees effectively reduces the sprouting rate of the walnut trees.

Description

technical field [0001] The invention belongs to the technical field of fruit tree production, in particular to a special anti-stripping liquid for walnut trees. Background technique [0002] Stripping refers to the phenomenon that the branches of fruit trees dry up or even die due to low soil temperature, low humidity, and dry air in winter and spring, and the aboveground part of the tree loses more water through transpiration than the root system supplies water. In the northern region of my country, due to the large pith of the branches, loose tissue, relatively poor ability to retain water and resist water loss, etc., the walnut phenomenon often occurs, especially young trees, which seriously affects the yield and quality of walnuts. Economic benefits have become one of the key factors restricting the development of the walnut industry. In walnut production, there are a series of measures to prevent stripping, such as burying the soil to prevent cold, regulating tree vigor...
