Embodiment Construction

[0020] 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.

[0021] Pot load test soil treatment:

[0022] 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 belongs to the technical field of soil improvement and discloses a method for improving heavy soil in Sichuan, in particular a method for improving heavy soil in mountain areas around the Sichuan basin. According to the method, firstly, a potted plant test is adopted, and three kinds of soil with good effects are screened out on the basis of an early-stage test to carry out a precisetest; asparagus is used as a test crop to verify the actual effect of the soil on the crop. After soil improvement measures are implemented, the pH value of the soil is changed from 5.0 to 6.8 and completely meets the requirement for planting the asparagus. The soil texture is changed from the original level of heavy soil to the level of moderate loam soil; the effect of soil improvement is veryobvious; secondly, the growth condition of asparagus plants on the three kinds of improved soil is obviously better than that of a control group, the harvesting amount of the asparagus per mu is at least four times greater than the original amount, and therefore the difference is remarkable.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates 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 allevia...
