Plant cultivation structure and method in desert area

Abstract

The invention relates to a plant cultivation structure and method, in particular to a cultivation structure and method for increasing a plant survival rate in a desert area. The cultivation structure comprises a base layer, an impermeable layer, an improved substrate layer, an irrigation layer and an evaporation prevention layer sequentially from the bottom up, wherein the base layer is desert raw soil; the impermeable layer is formed by mixing clay and the desert raw soil; the improved substrate layer comprises park waste, agricultural waste, mushroom bran, bacterial manure and the desert raw soil; the irrigation layer comprises an irrigation pipe; and the evaporation prevention layer is made from wheat reeds. The method comprises the step of cultivating a plant with the soil structure. The structure and the method have the advantages of improving the soil, keeping moisture and increasing the plant cultivation survival rate in the desert area.

Description

technical field [0001] The invention relates to a plant planting structure and method, in particular to a planting structure and method for improving plant survival rate in desert areas. Background technique [0002] my country is a country with a wide distribution of deserts and desertification in the world, and it is also one of the countries most affected by desertification in the world. The total area of ​​deserts is 1.28 million square kilometers, accounting for about 1 / 7 of the country's land area. The land area that has been desertified is 176,000 square kilometers, and the land area that is potentially dangerous for desertification is 158,000 square kilometers. The desert, Gobi, and desertified land in the northern region has exceeded 1.49 million square kilometers, accounting for about 15.5% of the country's land area. Desert control has become a long and arduous task. At present, people use a variety of methods to prevent and control desertification. Among them, ...

Problems solved by technology

[0003] However, there are a series of problems in the cultivation of desert plants, such as insufficient water resources and large fluidity of sand bodies, which make the survival rate of plants low and bring great obstacles to the control of desertification.

[0004] For this reason, the publication number is "CN103718883A, a structure and method for planting desert greening" which proposes a structure and method for planting greening in desert areas, but in terms of irrigation, the planting bag is provided with an irrigation device directly facing the root system of the plant. The bag is buried in the ground, and the construction is relatively inconvenient. In addition, the publication number is "CN102308688A, Desert Planting Structure and Method for Improving Soil and Planting Method" also proposed the structure and method of green planting in desert areas. The main improvement point is the air-permeable anti-seepage layer In terms of improvement, the soil body has not been optimized, and there is no certain irrigation and water storage settings, so the use has certain limitations
