Method for preserving moisture in pearl guava planting process

Abstract

The invention belongs to the technical field of planting and moisture preservation and in particular relates to a method for preserving moisture in a pearl guava planting process. The method comprises the following steps: (1) smoothening a sand land; flatly spreading a water-retaining agent and cassava starch on the surface of the sand land, wherein the water-retaining agent is prepared from the following components in parts by weight: 20 to 25 parts of calcium chloride, 10 to 15 parts of magnesium silicate, 5 to 10 parts of talcum powder and 2 to 8 parts of polyvinylpyrrolidone; (2) sufficiently mixing the water-retaining agent, the cassava starch and sand through a mechanical rotary tillage manner to obtain a compound layer with the thickness of 20cm to 30cm, wherein in the compound layer, the volume ratio of the water-retaining agent to the cassava starch to the sand is 1 to (2 to 3) to (5 to 6). The sand land modified by the method provided by invention has relatively good water-preserving and water-retaining performance and the problem that the moisture of the sand land leaks seriously is solved; the method is suitable for planting pearl guavas and the effects of obtaining raw materials locally, utilizing the raw materials locally, taking measures to suit local conditions and changing harmful things to valuable things are realized.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of water conservation in planting, in particular to a water conservation method for planting pearl guavas. [0003] 【Background technique】 [0004] Sand particles have large pores, good permeability, few small pores, weak capillary action, loose texture, poor water retention, and weak water storage capacity. Due to the uniform texture, once the water supply decreases and evaporation increases, it is prone to overall water shortage; at the same time The organic matter in the sand decomposes quickly and accumulates less, resulting in poor fertilizer retention and relatively poor nutrients. The lack of water and the loss of nutrients lead to low productivity in sandy land, and the survival rate of seedlings planted in sandy land is low. Therefore, the problem of water conservation in sandy land has become an urgent problem in the field of sandy land governance. [0005] For the cultivation of pearl gua...
