Desert greening plantation structure and method

Abstract

The invention relates to the technical field of desert greening plantation, in particular to a desert greening plantation structure and method. In recent years, in order to increase income, local people try to plant the agricultural products such as red dates, however all the agricultural products cannot stand the dry sandstorm during the summer, the seedlings which already have 5-8 leaves are burned to death by high temperature sandstorm. The desert greening structure comprises protection forest arranged at the periphery of a newly reclaimed desert turf, crops with wind prevention and sand fixation properties arranged in the desert turf, secondary crops with wind prevention and sand fixation properties, and economic forest. The second crop with wind prevention and sand fixation properties is arranged between crops with wind prevention and sand fixation properties, and economic forest is arranged between secondary crops with wind prevention and sand fixation properties. According to the desert greening plantation structure, the intercropping fruit and vegetable model which uses wheat for wind protection for muskmelon plantation is used, the wheat is planted before wind seasons, when the wind seasons come, the height of the wheat already grows to more than 50cm, if the climate with frequent sandstorms are encountered, the date seedlings can be protected, the muskmelon seedlings suffer no loss, the seedling survival rate attains 87%-93%. The effects of wind prevention and sand fixation are enhanced to the most extent, and at the same time, the goal of improving desert ecological environment is achieved.

Description

technical field [0001] The invention relates to the technical field of desert greening planting, in particular to a desert greening planting structure and method. Background technique [0002] The Taklamakan Desert is located in the center of the Tarim Basin in southern Xinjiang. It is the largest desert in China, the tenth largest desert in the world, and the second largest mobile desert in the world. The entire desert is about 1,000 kilometers long from east to west, 400 kilometers wide from north to south, and covers an area of ​​330,000 square kilometers. The average annual precipitation does not exceed 100 millimeters, the lowest is only four or five millimeters; while the average evaporation is as high as 2500-3400 millimeters. Here, pyramid-shaped dunes rise 300 meters above the plain. The wind can blow the sand wall up to three times its height. The sand dunes in the desert stretch continuously, and are affected by the wind, and the sand dunes often move. There a...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, solve the high cost of planting crops in the desert area of ​​Hetian area, the high cost of windbreak and sand-fixing effect, the seedling rate and yield are low, and economic benefits cannot be produced in that year; the planting structure is unreasonable , the traditional technical problems of low survival rate caused by unsuitable planting varieties, water and fertilizer matching and unreasonable post-management
