Fertilizer special for persimmon trees and preparation method thereof

Abstract

The invention discloses a fertilizer special for persimmon trees and a preparation method thereof. The fertilizer comprises the following raw materials by weight part: 40-50 of a nitrogen phosphorus potassium compound fertilizer, 23-25 of loess, 20-25 of magnetite powder, 13-15 of distiller's grains, 12-15 of rice husk straw, 8-9 of bamboo charcoal powder, 12-15 of wheat straw, 2-4 of citric acid, 2-3 of calcium superphosphate, 1-2 of potassium sulfate, 0.6-0.8 of sodium naphthalene acetate, 0.5-0.7 of polyethylene glycol, 0.1-0.3 of ammonium polyacrylate, 0.8-1.2 of boric acid, 7-9 of groundnut leaf, 3-5 of Paederia foetida, 2-4 of Clerodendrum bungei root, 1-3 of Scirpus triangulates root, 5-7 of Alternanthera philoxeroides, and 1-3 of an EM original solution. The fertilizer provided by the invention has the advantages of simple technological ratio, low cost and small side effect. Through the polymerization principle of methyl methacrylate, the wheat straw and corn flour are fully combined with potassium sulfate powder so as to reach certain slow release effect. The organic fertilizer can reach high yield at small dosage, and improves the quality of persimmon trees.

Description

technical field [0001] The invention relates to the field of manufacturing organic fertilizers, in particular to a special fertilizer for persimmon trees and a preparation method thereof. Background technique [0002] my country is a large agricultural production country. With the high utilization of fertilizers, the requirements for fertilizers are constantly increasing. At present, a large amount of inorganic fertilizers are used, which seriously leads to the increase of harmful substances in crops, poor quality, and incomplete nutrition. Secondly, the soil is prone to Hardening, poor drought resistance, and poor water retention performance, which seriously affects the normal growth of crops and poor economic benefits; for perennial perennial single nitrogen fertilizer regardless of land fertilizer supply capacity and persimmon tree fertilizer requirements in persimmon production The phenomenon of unscientific fertilization, according to the data of soil testing, researched ...
