Special compound fertilizer for desalted soil and capable of increasing rice yield

Abstract

The invention relates to the technical field of fertilizer production, and discloses a special compound fertilizer used for desalted soil and capable of increasing the rice yield. The compound fertilizer is prepared from the following raw materials in parts by weight: 80 to 130 parts of biogas residue, 20 to 30 parts of biogas slurry, 50 to 70 parts of urea, 100 to 120 parts of fermented livestock manure, 40 to 50 parts of calcium hydrogen phosphate, 1 to 5 parts of brown sugar, 10 to 25 parts of silicon fertilizer, 20 to 30 parts of magnesium chloride, 10 to 20 parts of ferric chloride, 10 to 20 parts of zinc chloride, 15 to 25 parts of boron fertilizer, 5 to 10 parts of manganese molybdate, 30 to 50 parts of nitrogen, 30 to 50 parts of humic acid, 30 to 50 parts of potassium, 1 to 5 parts of chitooligosaccharide, 10 to 20 parts of borax, 6 to 10 parts of betaine, 5 to 8 parts of seaweed meal, 5 to 8 parts of glycerol, 3 to 6 parts of grass ash and 1 to 3 parts of wormcast. The rice produced by using the compound fertilizer disclosed by the invention is neat in ear head, quick in filling, full in grains and good in yellowing during ripening, can effectively promote early-stage and middle-stage growth of the rice, and is beneficial to later-stage filling and dry matter accumulation, so that the highest yield is obtained, and the rice produced by using the compound fertilizer can improve the utilization rate of the fertilizer.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, in particular to a special compound fertilizer used in desalinated soil to increase rice yield. Background technique [0002] The fruit of rice is rice paddy, which is called brown rice after the chaff is removed, and rice can be obtained by grinding the rice bran layer off the brown rice. Nearly half of the world's population relies on rice as a staple food. In addition to being edible, rice can also be used as industrial raw materials for wine making and sugar refining. Rice husk and rice straw can be used as livestock feed. The main rice producing areas in China are mainly the Yangtze River Basin, the Pearl River Basin, and the Northeast region. Rice is a direct economic crop, and rice is the staple food of Chinese residents. [0003] Soil water-soluble salt is an important attribute of saline-alkali soil and an obstacle to crop growth.

[0003] Soil water-soluble salt is an important attribute of saline-alkali soil and an obstacle to crop growth. However, some soils in my country are divided into three types: medium saline soil, desalinated soil and yellow fluvo-aquic soil. The nutrients supplied to plants are also different. The fertilizers currently used in production include simple fertilizers and compound fertilizers. Their components are simple, their performance is single, and their fertilizer efficiency is low. special compound fertilizer
