Description
Technical Field
The invention belongs to the technical field of grassland desertification restoration, and particularly relates to a method for restoring grassland local sand.
Background
The grass area of China is huge, and the grass area accounts for about 40% of the territory area, and is widely distributed from east to west. The natural grassland area is continuously reduced, the quality is continuously reduced, the grassland carrying capacity is reduced, and the degraded grassland is continuously increased.
The warm grassland is one of main parts of European continental grassland, is also a main grassland type in China, is a natural ecological barrier in northern areas of China, and has important strategic significance for ecological safety in Beijing Ji areas and northern areas of China. However, the current grassland areas have a relatively low social interest in a plurality of small areas of local sand (plaque sand), the single area of the part of sand is small, generally 0.2-10 mu, the quantity is large, the desertification speed is extremely rapid, and the speed of 20 ten thousand mu per year is rapidly increasing, so that the sand is urgently needed to be treated.
The mobility of sand grains on the surface of a sand dune in a grassland sand field causes that plant root systems are difficult to fix on the ground, and the survival rate is low. The mechanical sand barrier is a necessary measure for ensuring plant survival and preventing sand damage, can improve the surface roughness, reduce the wind speed, effectively slow down wind erosion, fix a movable sand dune in a short period and increase the self-repairing capability of the sand. However, the grassland area is lack of material and the cost of purchasing sand barriers is high. Meanwhile, the grassland fertilization cost is high, and the operation is not easy.
At present, the existing sand treatment measures have long treatment period and high cost, and no repair method specially aiming at local sand of grasslands is adopted. Therefore, a repair method which is specially suitable for local sandy land of grassland and has good treatment effect, short treatment period and low cost is needed in the prior art.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a method for repairing the grassland local sand with good treatment effect, short treatment period, low cost and special pertinence.
The invention is realized by the following technical scheme: 1. a method for repairing grassland local sand comprises the following steps:
(1) For 4 months, adopting cow and sheep manure bricks, arranging a plurality of rows of longitudinal wind-shielding manure ridges which are perpendicular to the local main wind direction on a local sand land of a grassland, wherein the height is 7-10cm, and the distance between every two adjacent rows of longitudinal wind-shielding manure ridges is 300-500cm; the manure ridge can reduce the loss of ground soil, and simultaneously can 'spread' fertilizer for sandy land along with wind blowing and rain, so as to provide nutrients; the shallow plowing plow is used for plowing the local sand of the grassland between every two rows of longitudinal wind-shielding manure ridges and then raking the grassland, wherein the plowing depth is 10cm to 15cm;
(2) 5 months, sowing on the ploughing and raking sand, planting oat and sand between every two rows of longitudinal wind-shielding manure ridges, longitudinally planting oat according to ridges, spacing every two ridges by 60cm, and longitudinally planting sand according to ridges between every two adjacent longitudinal oat ridges; simultaneously, the oat is planted transversely according to ridges, and the distance between every two adjacent rows of transverse oat ridges is 1m; the sowing quantity of oat is 6 kg/mu, and the sowing quantity of sand is 2 kg/mu; the oat planted transversely and longitudinally according to ridges can form a biological yarn net, wind prevention and sand fixation and form a double protection mechanism with the manure bricks;
(3) After sowing, arranging transverse wind-shielding manure ridges between two adjacent rows of longitudinal wind-shielding manure ridges according to rows, wherein the height of each transverse wind-shielding manure ridge is 10cm, each row of transverse wind-shielding manure ridge is composed of more than two sections of transverse manure ridge sections, gaps are reserved between every two adjacent sections of transverse manure ridge sections, the distance between every two adjacent rows of transverse wind-shielding manure ridges is 10-15m, and the transverse manure ridge sections of the two adjacent rows of transverse wind-shielding manure ridges are staggered, so that the rainwater runoff is facilitated, fertilizer is flushed, meanwhile, the fertilizer is also 'spread' into the ground by wind, the soil fertility is improved, the nutrients are provided for plants, and the productivity is improved;
in the bean grass mixed sowing system of the invention, leguminous plants can fix nitrogen through rhizobium symbiotic with roots. These rhizobia bacteria are able to convert nitrogen in the air into nitrogen available to plants, a process known as nitrogen fixation. This helps leguminous plants to obtain nitrogen nutrition in the soil, helps them grow and provides more nitrogen for other plants, can improve soil fertility, and effectively restores the sandy ecological environment.
Planting rhizoma Curculiginis, herba Caprae Seu Ovis and herba Cryptospori Henryi between longitudinal sand making ridge and adjacent longitudinal herba Avenae Fatuae ridge (ridge spacing 15 cm), wherein the seeding rate of each plant is 0.2 kg/mu, and the rhizoma Curculiginis, herba Lespedezae Cuneatae and herba Cryptospori Henryi can grow and mature under the double protection mechanism of manure brick and plant in the late stage to provide seed stock. Only by mixing and sowing the sarcandra and the oat, the community diversity is low, and the plants such as the festuca arundinacea, the leymus chinensis and the cryptotazius hookeri are planted again, so that the community diversity is improved, complex correlations can be formed among species, the community stability can be improved, and the restoration of the sandy land is facilitated.
According to the loss amount of the longitudinal wind-shielding manure ridge and the transverse wind-shielding manure ridge, the cow manure and sheep manure bricks are supplemented each year, so that the soil nutrient supply is ensured, and the wind prevention and sand fixation are also realized.
The beneficial effects of the invention are as follows: according to the invention, local sand on grasslands is repaired by combining the wind-proof manure ridge sand barrier with the leguminous-gramineous plant. According to the invention, the cow and sheep manure bricks in the grassland area are effectively utilized to set manure ridge sand barriers, no additional fertilization is needed, the wind and the rainwater in the nature are utilized, the soil fertility is greatly improved, and a good windproof sand fixing effect is achieved. The method can effectively control the rapid expansion of the sand area and rapidly repair the local sand of the grassland. The method of the invention can prevent the expansion of the sand area in the first year; the coverage of the desertification grassland in the second year reaches 28%; the plant community in the third year tends to be stable and can be moderately grazed for use. The method is simple and convenient to operate and suitable for large-area popularization.
