Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0022] First of all, it is stated that in this application, the range of coal-to-soil ratio (abbreviation for mass ratio of weathered coal to loess or sand) includes the endpoint value.

[0023] Since humic acid, an abundant active substance contained in weathered coal, can promote plant growth, this example studies the effect of weathered coal on corn growth by applying weathered coal to loess.

[0024] In this example, indoor pot experiments are used to study the effects of soil with different ratios of weathered coal and loess on the growth of corn, the water use efficiency of corn, and the content of mineral elements absorbed by the aboveground part of corn, and the best mixture of weathered coal and loess is obtained. Ratio, rational use of weathered coal to promote corn growth, w...

Abstract

The invention discloses a water-retaining and fertility-enhancing soil improving method and improved soil. The soil improving method comprises the step of applying weathered coal in loess or sandy soil. The formed improved soil comprises loess or sandy soil and weathered coal applied into the loess or sandy soil. Preferably the ratio of applied weathered coal is that the mass ratio of the weathered coal to loess or sandy soil is between 1 to 2 and 1 to 1. According to the improving method disclosed by the invention, the weathered coal is applied into the soil to be mixed with the loess or sandy soil in different proportions so as to play a promoting role on crop growth and moisture utilization, so that a resource of the weathered coal and the improved soil are effectively utilized, and thereby, the water and enhancing the fertility is retained.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improvement method for retaining water and increasing fertilizer and improving soil. Background technique [0002] The western part of my country is located in an arid and semi-arid water-deficient area, and its water resource share is only 3.9% of the national total. Most of the soil fertility is relatively poor, the ecology is fragile, and the output of crops is low. For my country, a large agricultural country, improving the fertility of farmland soil and increasing water use efficiency will be the main problems that need to be solved urgently in the west. [0003] Weathered coal refers to coal exposed to the surface or located in the shallow layer of the surface, commonly known as outcrop coal. Due to the influence of long-term weathering, weathered coal has high oxygen content and low calorific value. However, it contains rich active substance humic acid, an...
