High-yield rice fertilizer and preparation method thereof

Abstract

The invention discloses high-yield rice fertilizer and a preparation method thereof. The high-yield rice fertilizer is prepared from the following raw material components in parts by weight: 45 to 65parts of urea, 3 to 8 parts of calcium magnesium phosphorus fertilizer, 8 to 16 parts of hydrogen carbonate diamine, 15 to 30 parts of potassium sulfate, 10 to 18 parts of calcium nitrate, 6 to 13 parts of magnesium sulfate, 3 to 7 parts of carboxymethyl chitosan, 2 to 6 parts of ferrous sulfate, 3 to 7 parts of sweet potato leaves, 6 to 11 parts of bamboo shoot shells, 4 to 9 parts of sodium metaborate, 6 to 13 parts of calcium superphosphate, 5 to 10 parts of nitrohumic acid, 2 to 5 parts of tea saponin, 6 to 10 parts of radix rehmanniae preparata, 4 to 8 parts of tea polyphenol, 1 to 3 parts of lignosulfonic acid, 2 to 6 parts of sodium silicate, 5 to 10 parts of polyacrylamide, 2 to 6 parts of zinc sulfate and 3 to 7 parts of nitrogen-fixing bacteria. The high-yield rice fertilizer provided by the invention has the advantages of low preparation cost, simple preparation method, high waste utilization rate and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a high-yield rice fertilizer and a preparation method thereof. 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. 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 Pearl River Basin. Belongs to direct economic crops. It is also the staple food of one-third o...

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
