Long-acting compound nutrient injection for fruit tree and applying method

Abstract

A long-acting composite nutritive liquid in the form of injection for fruit tree is prepared from chelating agent, urea, potassium nitrate, ferrous sulfate, zinc sulfate, magnesium sulfate, manganese sulfate, boric acid and water. Its advantages are long acting (one year), and high yield and quality of fruit.

Description

technical field [0001] The invention relates to a nutrient solution for fruit trees, more specifically, a long-acting compound nutrient injection for fruit trees. Background technique [0002] Traditional fruit tree fertilizers not only have a single nutrient, but also have backward application techniques. For example, the commonly used two fertilization techniques, soil fertilization and foliar spray fertilizer, the former fertilizer utilization rate is only 40%, and the latter utilization rate is less than 60%. This not only wastes resources, pollute the environment, and make the production cost of fruit growers remain high, seriously affecting the improvement of economic benefits. In order to change this situation, someone has developed fruit tree compound fertilizer such as CN1188597A patent application, which is based on β-cyclodextrin as the main raw material, supplemented with boron, zinc, calcium, phosphorus and active ingredients. The types are slightly increased c...

[0002] Traditional fruit tree fertilizers not only have a single nutrient, but also have backward application techniques. For example, the commonly used two fertilization techniques, soil fertilization and foliar spray fertilizer, the former fertilizer utilization rate is only 40%, and the latter utilization rate is less than 60%. This not only wastes resources, pollute the environment, and keep the production cost of fruit farmers high, seriously affecting the improvement of economic benefits

In order to change this situation, someone has developed fruit tree compound fertilizer such as CN1188597A patent application, which is based on β-cyclodextrin as the main raw material, supplemented with boron, zinc, calcium, phosphorus and active ingredients. The types of fertilizers are slightly increased compared with traditional fertilizers, but the application method is still traditional foliar spraying

Also someone develops fruit tree nutrition injection in addition, as CN1272476A patent application is to be the pear tree nutrition injection that gelatin, sucrose, urea, ferrous sulfate, zinc sulfate make as raw material, nutrient only contains N, Zn, Fe, and applicable The surface is limited to pear trees. According to its product manual, the injection method uses a pump for strong injection, which is easy to cause damage to the tree.
