Slow-release fertilizer for plantation of paddy rice

Abstract

The invention discloses a slow-release fertilizer for plantation of paddy rice. The slow-release fertilizer comprises the following raw materials by weight: 20 to 40 parts of urea, 8 to 16 parts of diammonium hydrogen phosphate, 8 to 16 parts of potassium sulfate, 8 to 16 parts of ammonium chloride, 5 to 15 parts of calcium magnesium phosphate fertilizer, 8 to 16 parts of potassium chloride, 2 to 10 parts of zinc sulfate, 2 to 10 parts of copper sulfate, 2 to 10 parts of sodium humate, 40 to 50 parts of poultry manure, 20 to 30 parts of corn straw, 20 to 30 parts of bagasse, 5 to 10 parts of an EM strain, 1 to 5 parts of triadimefon, 1 to 5 parts of a sustained-release agent, 0.2 to 1 part of manganese amino acid chelate, 0.2 to 1 part of iron amino acid chelate, 0.2 to 1 part of molybdenum amino acid chelate, 0.4 to 1.2 parts of a urease inhibitor and 0.4 to 1.2 parts of a nitration inhibitor. The slow-release fertilizer for plantation of paddy rice can guarantee absorption of a variety of trace elements in the growth of paddy rice and normal growth of paddy rice, enables nutrition to be balanced, promote growth of paddy rice, ensures output of paddy rice and prevents malnutrition of paddy rice.

Description

technical field [0001] The invention relates to the field of agricultural planting technical equipment, in particular to a slow-release fertilizer for rice planting. Background technique [0002] Rice is native to China, and rice was planted in the Yangtze River Basin of China 7,000 years ago. According to different methods, 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 ...

Problems solved by technology

[0004] Fertilizer is an important auxiliary in the process of planting crops. Whether rice can produce high-yield fertilizer plays an important role. Existing fertilizers often cannot ensure the absorption of various trace elements in rice, resulting in unbalanced nutrition and low rice yield.
