Embodiment 1

[0008] Embodiment 1: the improvement agent selects the plant rubber powder produced by Zhongke Guochang (Beijing) Technology Co., Ltd.; selects two acres of sandy land on the edge of the desert, and sows grass seeds on the sandy land; gets sandy soil with a grinder in the nearby sandy land Grind, add the ground sand and improver in proportion to the mixer and stir evenly, spread evenly on the desert surface where the grass seeds are sown, the thickness of the spreading layer is 10cm, and then evenly water the spreading layer with water. After the surface of the spraying layer is dry, a loose protective shell will be formed on the surface, and the protective shell can play a good role in fixing sand; after the protective shell is wetted with water again, the existence of the protective shell cannot be seen, but it is dry. The protective shell will then be re-formed. Since the protective shell is loose in texture, it will not affect the growth of vegetation. After two weeks, the...

Embodiment 2

[0010] Embodiment 2: The improvement agent is the same as Example 1; select two acres of sandy land on the edge of the desert, and sow grass seeds on the sandy land; get the sandy soil in the nearby sandy land and grind it with a grinder, and evenly spread the ground sandy soil on the ground. On the surface of the desert where the grass seeds are sown, the thickness of the spread layer is 8cm, and then the spread layer is evenly wetted and drenched with the prepared improver solution. After the surface of the spraying layer is dry, a loose protective shell will be formed on the surface, and the protective shell can play a good role in fixing sand; after the protective shell is wetted with water again, the existence of the protective shell cannot be seen, but it is dry. The protective shell will then be re-formed. Since the protective shell is loose in texture, it will not affect the growth of vegetation. After two weeks, the grass seeds generally emerge and grow well.

Abstract

The invention relates to a desert soil amendment and a method for improving desert soil. The amendment is a vegetable gum powder. The improving method is as follows: sandy soil in the desert is grinded by using a grinding machine in order that the sandy soil with a particle size of less than 0.074mm accounts for over 80wt%; then the desert soil is improved by one of the following two steps: step one, the amendment with a ratio of 100+ / -10kg amendment to the sandy soil per ton is mixed into the grinded sandy soil to obtain a mixture, the mixture is spread over the desert surface to be improved, and then the spreading layer is uniformly wet by water; step two, the grinded sandy soil is spread over the desert surface to be improved, an amendment solution is prepared, and the amendment solution is uniformly sprayed onto the spreading layer for penetrating the amendment solution into the spreading layer. The method has the advantages of no pollution to the environment, low good-cost and high efficiency, solves the problems of flows of sand dunes, sandy soil flying upwards with storms and low survival rates of sandy vegetation in the desert, and is suitable for a large area reconstruction of the desert.

Description

technical field [0001] The invention relates to a desert soil improvement agent and a desert soil improvement method thereof, belonging to the field of desert improvement. Background technique [0002] There are a large number of deserts in the world, and the area of ​​deserts and desertified land in my country is also very large, which seriously threatens the living environment of human beings. Since the founding of the People's Republic of China, the government has always been committed to desert transformation and has made great achievements. However, due to climate change and the impact of human activities, new desertified land is also constantly forming. In the past, the practice of transforming the desert was mainly to plant sandy vegetation and shelter forests on the edge of the desert, and gradually advance to the hinterland of the desert. Due to the drought and lack of rain in desert areas, the survival rate of sandy vegetation is not high. Although people have ado...
