Embodiment Construction

[0018] The present invention proposes a method for improving sticky and heavy soil in Sichuan. Firstly, a pot test is adopted, and 3 kinds of soils with good effects are screened out on the basis of previous tests for precise tests; asparagus is used as a test crop to verify its actual effect on crops; The following will be described in conjunction with the embodiments.

[0019] Pot load test soil treatment:

[0020] The present invention aims at improving the soil of 0-30 cm. The pot experiment was carried out with a diameter of 30 centimeters and a plastic nutrient bowl of 50 centimeters deep, with 40 centimeters of soil in the pot. Take back the 0-30 cm soil in the field, dry it, crush it, mix it evenly and sieve it (with a distance of 0.5 cm) to remove debris such as stones, add 14.1 g of quicklime (powder) to each pot, and put the test The soil and quicklime (powder) 380.7g of 27 large nutrient bowls used were mixed evenly, piled up and placed for 7 days. After 7 days,...

Abstract

The invention discloses a method for improving clay-heavy soil in Sichuan, which belongs to the technical field of soil improvement, in particular to a method for improving clay-heavy soil in mountainous areas around the Sichuan Basin. At first adopt pot experiment, screen out 3 kinds of soils with good effect on the basis of previous test and carry out accurate test; With asparagus as test crop, to verify its actual effect to crop; After the present invention implements soil improvement measure, the pH value of soil There are changes in current residence, from the original PH value of 5.0 to 6.8, fully meeting the requirements for planting asparagus; the soil texture has changed from the original heavy clay to the level close to medium loam; the effect of soil improvement is very obvious; the second three The growth of asparagus plants in the improved soil was also significantly better than that of the control group, and the asparagus harvested per mu had reached a significant difference level of more than four times the original one.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, in particular to a method for improving clay-heavy soil in Sichuan, specifically a method for improving clay-heavy soil in mountainous areas around the Sichuan Basin. Background technique [0002] In the mountains around the Sichuan Basin, there is a large area of ​​clay-heavy soil, which belongs to yellow loam, and is called "yellow mud soil" by local people. This soil is very sticky and heavy and only suitable for growing rice. In recent years, with the deepening of poverty alleviation work, in order to increase the income of local farmers, the adjustment of planting structure has been carried out. Asparagus, which is more than 5 times more profitable than rice planting, was selected as a breakthrough in industrial poverty alleviation. After trial planting, good results have been obtained. The local government decided to develop asparagus as an industrial poverty alleviation project...
