Problems solved by technology

[0003] However, on the exposed rock slope, the artificial soil is relatively primitive, attached to it by manpower, and does not exist in the original state. Insect eggs, weed seeds and other harmful organisms have low nutrient content. At the same time, the soil artificially implanted on the karst slope is subject to long-term strong leaching, the soil structure is easily destroyed, and there are differences in water holding capacity. Problems such as high loss rate and poor effect. The nutrient content in the soil is not high. After the loss, it cannot be supplemented, which will cause the lack of nutrient content.
Based on the above reasons, the vegetation cannot get a good growth environment, the growth is seriously restricted, and the rapid recovery of vegetation is affected.
[0004] Although there are many compound fertilizers on the market to supplement the nutrients needed by plants, the nutrients contained in these compound fertilizers are not complete. On the soil with poor water and fertility retention, excessive application of fertilizers not only causes production Increase in cost, decline in economic benefits, and also cause waste of fertilizers and environmental pollution, especially the destruction of soil micro-ecological environment

Abstract

The invention relates to a preparation method for a slow-release fertilizer aiming at difference of water-holding properties of a karst mountain land. The preparation method comprises the following steps: (1) preparing a coating material; (2) preparing a medicinal material; (3) carrying out fermenting so as to obtain a fermented material; (4) uniformly mixing raw materials, grinding mixed raw materials into powder, and carrying out filtering; (5) carrying out moisture adjustment; and (6) uniformly spraying the coating material so as to obtain the slow-release fertilizer. The method provided bythe invention has the following advantages: the process is simple; used raw materials are wide in source; the prepared slow-release fertilizer enables the soil adhesiveness of the karst mountain landto be high, reduces the difference of the water-holding properties; meanwhile, the cost is low, and the plant growth effect is good.

Description

technical field [0001] The invention relates to the technical field of fertilizer formulation and production, in particular to a method for preparing a slow-release fertilizer aiming at the difference in water-holding performance in karst mountains. Background technique [0002] Karst landform refers to various landforms formed by the dissolution of soluble rocks by water and the accompanying mechanical action. Karst landforms are widely distributed in Guangxi, Guizhou, Yunnan and other places in China. In recent years, with large-scale engineering construction, mining and a series of infrastructure construction, a large number of exposed slopes have been formed in karst landforms, resulting in a large number of rock and soil slopes that cannot recover vegetation. Vegetation coverage is difficult to achieve, and the existing karst shrub slope protection technology can effectively alleviate or even solve the vegetation restoration of these exposed rock slopes to a certain ext...
