Preparation method of rice fertilizer

Abstract

The invention discloses a preparation method of rice fertilizer and relates to the technical field of agriculture. The rice fertilizer is prepared by, by weight, 20-35 parts of mixed phosphorus fertilizer, 30-60 parts of urea, 5-10 parts of ammonium sulfate, 20-60 parts of potassium sulfate, 12-16 parts of calcium nitrate, 8-12 parts of magnesium sulfate, 2-5 parts of ethylene diamine tetraacetic acid iron, 2-4 parts of sweet potato leaf, 4-5 parts of bamboo shoot shell, 6-8 parts of carboxymethyl chitosan, 3-4 parts of lignocellulose, 2-4 parts of processed monkshood, 3-4 parts of radix rehmanniae preparata, 4-6 parts of tea polyphenols, 1-3 parts of lignosulfonic acid, 2-4 parts of zinc gluconate, 3-4 parts of organic acid, 1-2 parts of zinc sulfate and 4-6 parts of nitrogen-fixing bacteria. The preparation method has the advantages that the method is low in raw material cost, and the prepared rice fertilizer is high in quality, high in content, high in utilization rate, pure natural, green, good in economic benefit, capable of increasing rice yield, capable of satisfying the needs of massive farmers and promising in development aspect.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for preparing rice fertilizer. Background technique [0002] Rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice. Chinese scientist Yuan Longping has made great contributions to the research of hybrid rice and is known as the "father of hybrid rice". The fruit of rice is paddy, and paddy (grain) is called rice, fragrant rice, and rice after shelling. Nearly half of the world's population feeds on rice. There are various ways to eat rice, such as rice, rice porridge, rice cakes, rice cakes, rice wine and so on. In addition to being edible, rice can also be used as industrial raw materials for wine making and sugar refining, and rice husk and rice straw can be used as feed. The main rice producing areas in my country are mainly the Northeast region, the Yangtze River Basin, and the Pea...

Problems solved by technology

[0003] Some areas are dry and rainless, and the soil is prone to salinization, or the soil itself is saline-alkali land, and the land is hardened seriously. Common fertilizers cannot be completely absorbed by the roots, resulting in failure to meet the needs of the growing agriculture. Moreover, the rice planted in the prior art has The residual components of pesticides are harmful to the health of consumers to a certain extent. In the soil with excessive application of chemical fertilizers, the content of inorganic matter soars, the organic matter is weakened, the trace elements are unbalanced, and crop diseases and insect pests are becoming more and more serious. The secondary pollution caused by the leaching of chemical fertilizers into the groundwater or lakes with the rainwater is intensifying
