Embodiment 1

[0042] (1) The implementation time and the soil profile of the implementation site are as follows

[0043] Implementation location: Shandong Provincial Academy of Forestry Sciences (Dongying Branch, E118°41'33", N37°24'35") located in Dongcheng District, Dongying City, under the 6-year-old white wax forest, with a density of >0.7, and the soil under the forest Sampling survey, the measured soil pH in this area is 8.62, the salt content is 5.18‰, the soil is strong salinized soil, and the soil bulk density is 1.63g / m 3 , the porosity is 0.291, and the organic matter content is 6.14g / kg. The implementation site faces the Bohai Sea in the east, with flat terrain and rich sea salt resources. It is a sea soaking saline area with high soil salinization level, pH between 7.5 and 8.7, and salt content between 2‰ and 12‰. In some areas, the salinity is higher, and the soil texture is heavy; the groundwater has high salinity, and the groundwater table is shallow. Therefore, the threat ...

Embodiment 2

[0054] 10 meters away from the land plot of Example 1, another 30m*2m land plot was selected as a blank control land (soil physical and chemical properties are the same as the soil of Embodiment 1).

[0055] After the soil of Example 1 was returned to the field and degraded naturally for 3 months, the soil of Example 1 and the blank control group were respectively sampled to measure the physical and chemical properties and soil enzyme activity of the soil. The results are shown in Table 2 and Table 3.

[0056] Soil physical indicators: ring knife method to measure bulk density, pycnometer method to measure soil particle density, and formula (1) to calculate soil porosity.

[0057] Porosity = bulk density / soil particle density (1)

[0058] Soil chemistry and nutrient indicators: pH5:1 is measured by pHS-2C digital acidity meter, EC5:1 (conductivity) is measured by DDS-11A conductivity meter, organic matter content is hydrated and heated by potassium dichromate oxidation-color...

Abstract

The invention discloses an improvement method of saline-alkali soil by utilizing stropharia rugoso annulata mushroom dregs. The method comprises the steps that fermentation compost is built and heapedand laid on the saline-alkali soil, and layering hole sowing is adopted for stropharia rugoso annulata mushroom cultures; through fruiting management, the temperature and the humidity are controlled;stropharia rugoso annulata mushrooms with the mature degree of 7-8 are harvested; mushroom dregs remaining after fruiting is completed and the saline-alkali soil are turned over, after natural degradation is completed, the pH, salt content and soil bulk density of the saline-alkali soil can be reduced, the porosity, organic matter content, rapidly-available phosphorus content, alkali-hydrolyzalenitrogen content and enzyme activity of the soil are improved, and the soil quality of the coastal saline-alkali soil in the yellow river delta is significantly improved. According to the method, planting is conducted on the saline-alkali soil, on one hand, the stropharia rugoso annulata mushroomes can be harvested to make profit, on the other hand, after the mushroom dregs are returned to the field, the soil quality can be effectively improved, and crops can be normally planted next year.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improvement, in particular to a method for improving saline-alkali soil by using stropharia stropharia spores. Background technique [0002] Saline-alkali soil is a general term for saline soil, alkaline soil, and various degrees of salinized and alkalized soil formed due to the action of saline-alkali components on the soil. Soil salinization refers to the enrichment of water-soluble salts in the soil. Soil alkalinization refers to the process of soil colloidal particles becoming sodium. Soil salinization leads to poor physical and chemical properties of the soil, which in turn causes most plants to The growth is inhibited or poisoned to varying degrees, and even cannot grow and survive. Soil degradation problems caused by soil salinization exist in more than 100 countries around the world. According to the second soil census data in China, the total area of ​​saline soil in China is...
