Method for quickly recovering healthy growth of dying fruit tree

Abstract

The invention discloses a method for quickly recovering healthy growth of a dying fruit tree. The method comprises two steps of fertilizing on the ground and spraying fertilizer on leaf surfaces and is carried out by the following steps of: after the fruit tree sprouts and comes into leafs, firstly, fertilizing on the ground for treatment, i.e. by taking a tree trunk as a circle centre, selecting 6-10 points in equal distance along the circumference taking the vertical projection of a crown as a circle area formed, punching holes with the diameter of 10cm and the depth of 50cm at each point, irrigating 0.5-1 kilogram of multi-element plant nutrition foliar fertilizer in each hole, and simultaneously spraying the same fertilizer on the crown with a dosage of 50 kilograms of the fertilizer in a unit of area; spraying the multi-element plant nutrition foliar fertilizer on the leaf surfaces twice after 7-10 days, and applying the fertilizer after 7-10 days with a dosage of 50 kilograms of the fertilizer in a unit of area; spraying high-nitrogen foliar fertilizer in a young fruit stage with a dosage of 100 kilograms of the fertilizer in a unit of area; in a fruit expanding period, continuously spraying high-potassium foliar fertilizer twice and spraying the fertilizer on leaf surfaces every 10 days with a dosage of 100 kilograms of the fertilizer in a unit of area for each time; and spraying the multi-element plant nutrition foliar fertilizer once after picking with a dosage of 50 kilograms of the fertilizer in a unit of area.

Description

technical field [0001] The invention relates to a nutrient fertilization technology capable of quickly saving sick fruit trees, and can also be used to overcome obstacles to replanting of fruit trees. Background technique [0002] Fruit trees are perennial trees. In recent years, the fruit tree industry in my country has developed rapidly. The cultivation of fruit trees tends to be dwarfed and densely planted, and the life cycle is shortened. The problem of reuse of old orchards is becoming more and more prominent. Therefore, the obstacle to replanting of fruit trees tends to be serious. It often shows that the plants are short, the growth is weak, the resistance is reduced, and even death. The main reason is that the long-term use of nitrogen, phosphorus and potassium fertilizers as the mainstay, lack of input of medium and trace essential nutrients and beneficial elements, weakens the internal "physique" of the tree. In addition, fertilization is often applied shallowly ...

Problems solved by technology

In addition, because the roots are shallow and the leaves are declining, in order to maintain a certain yield, fruit farmers are not allowed to increase topdressing after spring. However, the low utilization rate of fertilizers not only increases the cost, but also damages the roots many times at critical moments, further accelerating the decline of the tree.

Due to weak tree vigor, rampant pests and diseases, the frequency of pesticide use is increasing day by day, but the effect is gradually declining, coupled with the serious imbalance of nutrient input, which not only leads to the decline of fruit trees, but also leads to a serious decline in quality and yield, which leads to serious orchard degradation
