Water-fertilizer integral fertilization method for improving quality of peaches and gumming disease resistance of peach trees

Abstract

The invention relates to a water-fertilizer integral fertilization method for improving quality of peaches and gumming disease resistance of peach trees. The water-fertilizer integral fertilization method comprises the following steps: at the germination stage of peach trees, applying a germination before-flower fertilizer; at the stone hardening stage of the peach trees, applying a nitrogen-calcium-magnesium fertilizer, microbial agents and a liquid-level calcium fertilizer; at the later fruit setting stage, applying a fruit enlarging fertilizer; at the fruit falling stage, applying a base fertilizer. By adopting the water-fertilizer integral fertilization method, a microorganism bacterial fertilizer, the microbial agents, organic fertilizers, soil conditioning agents and inorganic fertilizers are used in match, in addition to a large number of microorganisms, large / medium elements such as nitrogen, phosphorus, potassium, calcium and magnesium and nutrient substances such as small-molecular instant organic matters, active fulvic acid, compound amino acids and biostimulants are available, and multiple nutrient components play a role of synergism, so that the tree vigor is improved, and the treatment rate of gumming diseases is increased; by adopting the water-fertilizer integral fertilization method, the labor is saved, the working intensity is alleviated, and the working efficiency is improved; the small-molecular instant organic matters and the active fulvic aid have the characteristics of improving fruit quality and improving fruit flavor .

Description

technical field [0001] The invention relates to a water and fertilizer integrated fertilization method for improving the quality of peaches and increasing the resistance of peach trees to gum disease, and belongs to the technical field of peach disease prevention and planting. Background technique [0002] In terms of nutritional requirements for peach trees, saplings mainly use phosphorus fertilizers, combined with appropriate amounts of nitrogen and potassium fertilizers, to induce root growth. After entering the full fruit period, the focus of fertilization is to coordinate the growth of branches and flowering results of peach trees. In terms of fertilization, nitrogen and potassium fertilizers are mainly used, and a certain amount of phosphorus fertilizer and trace elements are applied together. Every 100 kilograms of peach fruit needs to absorb 0.3-0.6 kilograms of nitrogen, 0.1-0.2 kilograms of phosphorus, and 0.3-0.7 kilograms of potassium. Every time 1000kg of fresh...

Problems solved by technology

[0004] The patent with application number 201510610043.6 discloses a method and device for fertilizing peaches. The defect of this fertilizing method is that it is inefficient and labor-saving, and the ratio of fertilizers for the last three topdressings is the same, which cannot satisfy the different growth of peach trees. The demand for different nutrient ratios in the period; the patent application number 201610425778.6 discloses a cultivation method of high-quality peach fruit trees. The defect of this method is that too much inorganic fertilizer is used in the later topdressing, especially the amount of urea is large, and the addition of Potassium sulfate, long-term use will cause soil compaction and acidification, resulting in weak tree vigor, gummosis and other serious diseases

[0005] At present, the fertilization method for peach trees has a huge labor input and low efficiency. There is no patent literature disclosure about the water and fertilizer integrated fertilization method for peach trees, nor is there any patent literature disclosure about the method for curing peach tree gummosis.
