A kind of desert greening planting structure and method

Abstract

The invention relates to the technical field of desert greening planting, in particular to a desert greening planting structure and method. In recent years, the local people have tried to grow red dates and other crops to increase their income, but none of them could withstand the hot and dry sandstorm in summer. The crop seedlings with 5-8 leaves were scalded to death by the high temperature wind and sandstorm. The desert greening planting structure of the present invention includes setting up protective forests around newly reclaimed desert plots, and setting windproof and sand-fixing crops, secondary windproof and sand-fixing crops and economic forests in the desert plots, and secondary windproof and sand-fixing crops are arranged between the windbreak and sand-fixing crops. crops, economic forests are set between the secondary windbreak and sand-fixing crops. The present invention adopts the intercropping mode of wheat melon intercropping and planting melons against the wind. Wheat is planted before the wind season, and the height of the wheat has grown to more than 50 cm when the wind season comes. The seedling rate is 87% to 93%, which maximizes the effect of windbreak and sand fixation, and at the same time achieves the goal of improving the desert ecological environment.

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
