Special fruit tree long-acting compound fertilizer production method of tree long-acting compound fertilizer special for fruit trees

Abstract

The invention discloses a special fruit tree long-acting compound fertilizer production method. The method comprises the following steps: (1) preparing urea formaldehyde pulp; (2) adding a conditioning agent adding; (3) polymerizing urea formaldehyde pulp; and (4) producing a plant growth regulator-containing long-acting compound fertilizer: after drying a urea formaldehyde polymer, calculating the effective contents of three major nitrogen, phosphorus and potassium in the compound fertilizer according to N, P2O5 and K2O, wherein the weight ratio of N to P2O5 to K2O is (14-18): (11-15): (11-15), then adding 15-20% by weight of organic matters, completely mixing and granulating so as to obtain a special plant growth regulator-containing fruit tree long-acting compound fertilizer. After a plant growth regulator is compounded with the long-acting compound fertilizer, plants well absorb nutrient elements, and the fertilizer has a quick effect, and moreover, the fertilizer can relieve antagonistic action, solve a fertilizer laying problem, avoid inorganic fertilizer-resistant disease and regulate nutrient balance, so that the fertilizer efficiency is multiplied.

Description

technical field [0001] The invention relates to a production technology of a special long-acting compound fertilizer for fruit trees, in particular to a production method for adding a plant growth regulator in the production process of a special long-acting compound fertilizer for fruit trees. Background technique [0002] Plant growth regulator is the product of the comprehensive development of various science and technology such as organic synthesis, microanalysis, plant physiology and biochemistry, and modern agriculture, forestry and horticulture. The plant growth regulator can quickly penetrate into the plant body after being in contact with the plant, promote the protoplasm flow of the cell, and improve the cell vitality. It can speed up the growth rate, break dormancy, promote growth and development, prevent flower drop, fruit cracking, and fruit shrinkage, improve product quality, increase yield, and improve crop resistance to disease, insects, drought, waterlogging,...
