A kind of special fertilizer for peach tree and its preparation method and application

Abstract

The invention discloses a fertilizer special for peach trees. The fertilizer consists of the following components in parts by weight: 60-80 parts of urea, 15-35 parts of starch, 20-30 parts of formaldehyde, 10-20 parts of diammonium phosphate, 15-30 parts of potassium sulfate, 5-15 parts of borax, 10-15 parts of ferrous sulfate, 10-15 parts of zinc sulfate, 5-15 parts of manganese sulfate, 5-15 parts of magnesium sulfate, 40-50 parts of calcium carbonate, 2-5 parts of resin coating agent, 2-10 percent of curing agent and 100-200 parts of water. According to the fertilizer special for peach trees, due to addition of the resin coating agent, the fertilizer can obtain a slow release function, and various elements of the fertilizer are slowly released to growth nutrient elements of the peach trees. The invention also provides a method for preparing the fertilizer. The method is simple and feasible and is suitable for large-scale implementation. By utilizing the fertilizer, fruit setting is induced, and the fruit setting rate of the peach trees is 78.76-88.65 percent.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a special fertilizer for peach trees and its preparation method and application. Background technique [0002] At present, the fertilizers for peach trees generally do not have a slow-release function. In addition, the nutrients in the fertilizers are not comprehensive, which leads to the ineffective absorption and utilization of fertilizers during the growth of peach trees, resulting in malnutrition in the later stage. In addition, it is necessary to reasonably adjust the fertilization during the fertilization process. Timing, resulting in nutrient imbalance and low fertilizer absorption and utilization, resulting in low yield of peach trees. Contents of the invention [0003] Purpose of the invention: the first technical problem to be solved by the present invention provides a special fertilizer for peach trees. [0004] The second technical problem to be sol...
