Desertification steppe family ranch Nitraria inter-sand pile lowland after-culture method

Abstract

The invention relates to a desertification steppe family ranch Nitraria inter-sand pile lowland after-culture method comprising the following steps: 1, selecting seeds, placing the seeds in a seedbedfor germination; 2, seedling, seedling on the germinated north china Ceratoides latens seed sand soil; 3, soil preparation: digging planting pits in to-be-cultured Nitraria inter-sand pile lowland, curing a cast pipe nearby each line of planting pits, setting cast holes connected with each planting pit in the line on the cast pipe, setting a water injection pipe with one end connected with the cast pipe, wherein the other end of the water injection pipe extends outside the sand ground surface and is connected with a water storage box on the ground on top of the Nitraria sand pile; 4, transplanting; 5, field management. The method cultures the seedlings before transplanting, thus ensuring the seedling survival rate after the cultivation; the cast pipe connected with the planting pits is arranged so as to realize underground cast, thus preventing water resource wastes in a surface spraying mode.

Description

technical field [0001] The invention relates to the technical field of desertification prevention and control, in particular to a method for replanting lowlands between Nitraria sand piles in family pastures in desertification grasslands. Background technique [0002] Soil desertification is a major threat to the world's agricultural development. It degrades the reproductive capacity of the land, reduces the production capacity of agriculture and animal husbandry and biological yield, and reduces the area of ​​available arable land and pasture. Soil erosion and land barrenness caused by desertification have resulted in years of famine in many countries. The land affected by desertification in the world has reached 38 million square kilometers. The land lost due to desertification is as high as 5 to 7 square kilometers every year, and almost 11 hectares of land are desertified every minute. If desertification continues without effective restraint, by the end of this century...

AI Technical Summary

Problems solved by technology

[0003] Since the implementation of the family pasture rotation grazing system in the desertified grassland area, the restoration of degraded grassland vegetation and the construction of artificial forage land have achieved remarkable results, but the utilization of the lowland between the hills in the family pasture Nitraria sand piles in the desertified grassland area is very low, and the people in the pastoral area cannot effectively graze Utilization, the problem is that the lowland between the sand piles of Nitraria is seriously degraded, the site conditions are poor, and it is difficult to establish

[0004] In the prior art, the planting of North China camel's hair is directly planted on the planting site, and the surface is watered by sprinkling water. After sowing, the survival rate of North China's camel's hair is low, and because the external temperature of the sandy land is high during the day, As a result, most of the poured water is evaporated, and a large amount of water is lost, resulting in a waste of water resources
