specific Embodiment approach 1

[0019] Specific embodiment 1: The soda saline-alkaline paddy field improver of this embodiment is composed of 4 to 6 parts of polyferric sulfate, 1 to 3 parts of aluminum sulfate, 1 to 3 parts of calcium nitrate and 0.5 to 1.5 parts of microorganisms according to the ratio of parts by weight. Composition of bacterial agent or bacterial fertilizer.

[0020] The polymeric ferric sulfate in this embodiment is liquid polyferric sulfate, purchased from Yingkou Xingye Chemical Co., Ltd., with a total iron content of ≥20.0%, and a pH of 2.0-3.0; aluminum sulfate is aluminum sulfate powder purchased from Jinzhou Jingong Chemical Co., Ltd.; nitric acid Calcium was calcium nitrate particles purchased from Langfang Pengcai Fine Chemical Co., Ltd., fertilizer grade.

specific Embodiment approach 2

[0021] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the microbial agent is a phosphorus-dissolving and growth-promoting agent. Others are the same as the first embodiment.

[0022] The microbial agent of this embodiment is a phosphorus-dissolving and growth-promoting agent from Shandong Maikezhen Biotechnology Co., Ltd., with Bacillus subtilis ≥ 200 million / mL and exopolysaccharide ≥ 1.0 mg / mL.

specific Embodiment approach 3

[0023] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the microbial fertilizer is potassium fulvic acid and high potassium type. Others are the same as the first embodiment.

[0024] The microbial bacterial fertilizer in this embodiment is potassium fulvic acid high-potassium type, produced by Jinan Zhongjie Biotechnology Co., Ltd., with fulvic acid ≥ 50%, organic matter ≥ 70%, organic potassium ≥ 10%, and 100% fully soluble.

[0025] Embodiment 4: The soda saline-alkali paddy field improver described in Embodiment 1 carries out an integrated homogeneous improvement method according to the following steps:

[0026] 1. Preparation of improver: Weigh 4 to 6 parts of polyferric sulfate, 1 to 3 parts of aluminum sulfate, 1 to 3 parts of calcium nitrate and 0.5 to 1.5 parts of microbial agent or fertilizer according to the weight ratio Mixing, the mixture is mixed with water at a ratio of 1:0.8 to 1.2 by weight to obtain a liquid modifier;

Abstract

A paddy field improver and an integrated homogeneous improvement method for soda saline-alkali land. The invention relates to an improver and an improvement method. The invention solves the problems of large transport and application amount of the improver and poor homogenization effect when improving the soda saline-alkali paddy field at present. The improver of the present invention is composed of polyferric sulfate, aluminum sulfate, calcium nitrate, microbial agent or bacterial fertilizer; method: 1. Preparation of improver; Fertilize. The paddy field improver of the present invention is completely soluble in water and can move freely with irrigation water, which not only realizes the integration of irrigation improvement, but also facilitates the automatic accumulation of the improver in areas with heavy soil salinity and achieves the effect of homogeneous improvement; The invention has strong operability, simple and easy raw materials, safety and non-toxicity, convenient transportation, easy solubility in water, convenient application, low cost and significant synergistic effect, and has great application value for soil improvement of soda saline-alkali paddy fields.

Description

technical field [0001] The invention relates to an improving agent and an improving method. Background technique [0002] The western part of the Songnen Plain in Northeast China is the concentrated distribution area of ​​soda saline-alkali soil in my country. The soil salinity is mainly sodium carbonate and sodium bicarbonate, the soil pH and alkalization are high, and sodium is serious. In the struggle against salinity, it was found that planting rice is an effective way to improve saline-alkali land. Since the beginning of the 21st century, under the guidance of the national plan to increase grain production by 100 billion catties, the region has launched a large-scale project to develop rice in soda saline-alkali land, which has played an important role in increasing grain production and improving the ecological environment. Due to the high degree of soil salinization, soil improvement has become a prerequisite for planting rice, so a large number of soil improvement con...
