Abstract

The invention discloses a slow-release fertilizer special for rice. The slow-release fertilizer is prepared from, by weight, 53-58 parts of livestock and poultry excrement, 42-46 parts of corn stalks, 18-22 parts of soya-bean cakes, 15-20 parts of humic acid, 4-7 parts of talcum powder, 4-8 parts of zeolite powder, 6-10 parts of calcium bentonite, 2-5 parts of kieselguhr, 13-16 parts of urea, 11-15 parts of ammonium dihydrogen phosphate, 6-10 parts of potassium sulphate, 1-3 parts of sodium citrate, 0.2-0.6 part of molybdenum sulfate, 0.5-0.9 part of boron sulfate, 0.3-0.8 part of zinc sulfate, 16-20 parts of paraffin and 12-15 parts of coated resin. The invention further discloses a preparation method of the slow-release fertilizer special for rice. The fertilizer can provide complete nutrition for rice, improve the physicochemical property of rice and raise the yield of rice.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special slow-release fertilizer for rice and a preparation method thereof. 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 refi...
