Embodiment 1

[0043] The site is located in Dagang District, Binhai New Area, Tianjin City, facing the Bohai Sea in the east, with a flat terrain and a coastline of 34 kilometers. It is rich in sea salt resources. It is a sea-soaked saline area. The soil salinization level is high, and the pH is between 7.8 and 8.5. The salt content is between 0.2% and 1.7%. In some areas, the salinity is higher, and the soil texture is heavy; the groundwater has a high salt content and the groundwater table is shallow, so the threat of secondary salinization of the soil is great.

[0044] 1. The soil profile of the implementation time and implementation site is as follows:

[0045]Implementation time: September 5, 2015. The implementation site is located in an open space south of Xuefu Road, Dagang District, Binhai New Area, Tianjin. The soil was sampled and investigated, and the soil pH in this area was measured to be 7.84, with a salt content of 0.39%. The soil was clay. Soil bulk density is 1.61g / m 3 ,...

Abstract

The invention relates to a method for improving saline-alkaline soil by using Cordyceps fermented liquid, the steps are as follows: (1) Cordyceps fermented liquid is subjected to high-temperature inactivation treatment; (2) Straw or sawdust and organic fertilizer are uniformly mixed according to a mass ratio of 1:1 to 5, and then made into a solid state Adsorption carrier; (3) make a mixture of solid adsorption carrier and Cordyceps fermented liquid according to the mass ratio of 1:5 to 10; : 1 ~ 5: 1 ~ 2 mass ratio mixed evenly to make composite bacteria; (5) adding composite bacteria to the mixture according to the mass ratio of 0.01-0.05%, and performing fermentation treatment to obtain soil improver; (6) the soil improver obtained in step (5) Sprinkle evenly on the saline-alkali soil and mix evenly, and the application amount of the soil improver is 5-20% of the saline-alkali soil quality. After the method of the invention improves the soil, it can not only adjust the soil pH, reduce the soil bulk density, increase the soil porosity and the proportion of soil aggregates, but also increase the soil fertility, promote the growth of plants in saline-alkali land and increase the crop yield.

Description

technical field [0001] The invention belongs to the field of saline-alkali soil improvement, and relates to a fermented liquid of Cordyceps sinensis, in particular to a saline-alkaline soil improver using the fermented liquid of Cordyceps sinensis as a raw material, a preparation method and application thereof. Background technique [0002] Saline-alkali soil includes two kinds of soils with different properties: saline soil and alkaline soil. Saline soil mainly refers to the soil containing excessive water-soluble salt in the soil. Alkaline soil mainly refers to the water-soluble alkaline salt in the soil, which shows a strong alkaline reaction. Due to the high salinity and high alkalinity of the salinized soil, the soil humus is leached and the soil structure is damaged. It is sticky when wet and hard when dry. There are often white salt deposits on the soil surface. Can cause plant wilting poisoning and root rot death. [0003] Land salinization is a worldwide problem ...
