Problems solved by technology

[0002] The disadvantages of existing facility soil secondary salinization prevention and control technology are as follows: 1. Reasonable fertilization: mainly from the control of nitrogen application amount, local nitrogen application, nitrogen, nitrogen, phosphorus, combined application, NO 3 - and NH 4 + It is recommended to start with root fertilizer and other aspects, but for these aspects, the vegetable farmers are required to have a high level of technology, and it is difficult to control and master
2. Application of nitrification inhibitors. This method has high co...

Embodiment 1

[0013] 1. Raw materials: Choose weathered coal from Zhanwuchuan, Inner Mongolia (total humic acid content 42.5%, ash content 11.3%), zeolite ore from Jiutai, Jilin, containing 70% clinoptilolite, and cation exchange capacity 150cmol / kg. Mishan vermiculite in Heilongjiang Province contains 88.5% expanded vermiculite. Calculated in parts by weight, weathered coal: zeolite: vermiculite = 1:0.4:0.25.

[0014] 2. Preparation:

[0015] (1) The weathered coal is crushed until it passes through an 80-mesh sieve, and HNO with a coal-acid ratio of 1:0.4 and a concentration ratio of 50% is added 3 solution. The exothermic reaction can maintain the temperature at 85°C for oxidation and nitration reactions until 2 hours after the reaction; add 25% ammonia water at a concentration ratio of 1:0.6 to the weight of coal.

[0016] (2) The zeolite is pulverized to 100-150 mesh, treated at a high temperature of 300°C to 350°C, and cooled for later use.

[0017] (3) Mix the product obtained in...

Embodiment 2

[0019] 1. Raw material: select Luobei lignite in Heilongjiang Province (total humic acid content 62.4%, ash content 10.6%), zeolite ore in Muling, Heilongjiang Province, containing 75% clinoptilolite, and cation exchange capacity 125cmol / kg. Vermiculite from Mishan, Heilongjiang Province contains 88.5% expanded vermiculite. Calculated according to the ratio of parts by weight, lignite: zeolite: vermiculite=1:0.5:0.15.

[0020] 2. Preparation:

[0021] (1) The weathered coal is crushed until it passes through an 80-mesh sieve, and HNO with a coal-acid ratio of 1:0.4 and a concentration ratio of 50% is added 3 solution. The exothermic reaction can maintain the temperature at 95°C for oxidation and nitration reactions until 1 hour after the reaction; add 25% ammonia water at a concentration ratio of 1:0.6 to coal weight.

[0022] (2) The zeolite is pulverized to 100-150 mesh, treated at a high temperature of 300°C to 350°C, and cooled for later use.

[0023] (3) Mix the produ...

Abstract

The invention provides a modifier for secondary salinization of facility horticulture soil and a preparation method thereof. The raw materials comprise weathered coal or brown coal, zeolite and vermiculite of 1: (0.4-0.5): (0.15-0.25) parts by weight. The invention is a technique for preventing the secondary salinization of facility soil, and a modifier prepared according to the origin characteristic of the secondary salinization of facility soil and the fertilizer requirement of vegetables through the scientific experiments for years. The modifier for secondary salinization of facility horticulture soil has the advantages of rational product formula, obvious salt reducing effect, greatly increased yield of vegetables, easy application for farmers and distinct economic benefit. The inventive modifier and applied technology thereof can effectively treat the secondary salinization of facility soil, improve facility soil environment, balance nutrients of crops, and increase the yield and quality of vegetables and are favorable to the sustainable usage of the facility soil. The inventive method and product can effectively reduce the salt of soil by 30%-60% and increase the yield of vegetables by more than 10%.

Description

(1) Technical field [0001] The invention relates to a technology for preventing and controlling secondary salinization of protected gardening soil, in particular to an improving agent and a preparation technology thereof. (2) Background technology [0002] The disadvantages of existing facility soil secondary salinization prevention and control technology are as follows: 1. Reasonable fertilization: mainly from the control of nitrogen application amount, local nitrogen application, nitrogen, nitrogen, phosphorus, combined application, NO 3 - and NH 4 + It is recommended to start with root topdressing, but for these aspects, the vegetable farmers are required to have a high level of technology, which is not easy to control and master. 2. Application of nitrification inhibitors. This method has high cost and is difficult to popularize and apply. In addition, the added nitrification inhibitors may cause secondary pollution. 3. Use reasonable water control measures to wash s...
