Abstract
The invention discloses an erosion-reducing tillage method for slope soil. After the soil is turned over, seeds are sown, and then erosion of surface runoff to farmland soil is reduced by adopting a straw coverage method on a slope tillage land. The method comprises the following steps of: transversely covering the complete straws on the field ridges of the farmland, planting crops on two sides of the field ridges, covering soil on the local straws and pressing the soil. The straws have high storage quantity in rural areas, are easily obtained and can improve the physicochemical property of the soil when returned to the field. The construction project is simple, one-time construction can be reused for many years, the investment is low, and the ecological and economic benefits are remarkable.
Description
Technical field
The present invention designs a kind of methods of cultivation of slope soil corrosion inhibitor, is suitable for loess plateau steep hillslope water and soil loss agricultural measures especially and administers the field.
Background technology
Water and soil loss is a global ecological environment problem.China is one of the most serious country of water and soil loss, according to whole nation water and soil loss for the second time remote sensing investigation, late 1990s, China water and soil loss area 3,560,000 km
2, wherein: the water erosion area: 1,650,000 km
2, particularly be positioned at the Loess Plateau in middle reaches, the Yellow River, corrode very seriously, mean sediment runoff reaches 1,600,000,000 t for many years.
The loess plateau is one of the most serious zone of global water and soil loss, also is the two poor zones of China's ecological economy.At present mainly containing woods grass construction project and basic farmland construction projects such as the Grain for Green Project having implemented to reach 10 years, terrace construction engineering aspect this regional bringing soil erosion under control.But because special landforms class and soil property, the hillside fields area still has very big area in this zone, and water that in addition should zone loess is protected characteristic, and the water and soil loss problem is still very serious; Secondly, this zone rural economy falls behind, and simple forest plantation such as implementation conceding the land to forestry grass construction project can reduce regional arable area undoubtedly, has influence on common people's income and grain security problem.Therefore, by making up the important measures that hillside fields corrosion inhibitor type farming system is this zone water and soil loss of reply, solution urban residents income.
The conservation tillage method administers the farmland water erosion at home and abroad and there is long history the wind erosion aspect; tillage control measure such as adopt to cover, no-tillage, can not only reduce water and soil loss, improve the availability of water resource; and can coordinate water, fertilizer, heat in the soil, improve soil moisture content.Mainly based on wind erosion prevention and control zone, Sha Qu farmland, northwest, the popularization in hillside fields also has, but lacks corresponding techniques system and standard in the popularization of China.Current having of being widely used in China's agricultural production covers and the methods of cultivation such as ridging covering, and cladding material is based on stalk and mulch film.
Summary of the invention
Technical problem to be solved by this invention provides a kind of methods of cultivation of slope soil corrosion inhibitor.
Technical solution of the present invention is as follows:
A kind of methods of cultivation of slope soil corrosion inhibitor, after soil turned over, sowing, adopt the stalk cladding process to reduce the erosion of rainwash on ploughing on the slope then to agricultural land soil, specific practice is: whole of stalk laterally is covered in the field of farmland, described field planted on two sides crops, the local suppression of soil of described stalk.
The described methods of cultivation, described type of seeding are the beans program request, perhaps cereal trench sowing.
The described methods of cultivation, mu consumption 3500-7500kg/hm
2
The described methods of cultivation, the kind of described crops is based on native breed.
The described methods of cultivation, the gradient of ploughing in described slope is 10 °～30 °
Stalk is big at the rural area amount, obtains easily, and stalk covers not only has the steady temperature effect of good water conservation, has realized the recycling of agricultural wastes again, the effect that has more fertilizing soil and prevent erosion.
Description of drawings
The schematic diagram that Fig. 1 covers for embodiment of the invention stalk.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
A slice gradient that test site is chosen in erosion of research soil and water conservation institute of Ministry of Water Resources of Chinese Academy of Sciences Shenmu County and environmental test station is on the arable land, slope of 12.5 ° (10 °～15 °), eight sub-districts are set, stalk covering, plastic mulching, the ridging plastic mulching of soybean and millet are set at random.
1, stalk covers: turn over, and the beans program request, the cereal trench sowing laterally is covered in whole of stalk in the field of farmland then, with the scattered suppression of soil block, described field planted on two sides crops; Distance between the ridges 50cm, stalk cover width 50cm, stalk consumption 3500kg/hm
2～4500kg/hm
2
2, plastic mulching: turn over beans program request, cereal trench sowing, sowing behavior 50cm.Then mulch film is tiled in sowing in the ranks, promptly intermembranous plantation, the wide 50cm of film.
3, ridging plastic mulching: ridging, row spacing 50cm.Spacing 100cm between top, ridge center line and top, the next ridge center line, the high 30cm in ridge.In both sides, ridge sowings, beans program request, the cereal trench sowing, and then with top, the whole ridge of plastic mulching, furrow does not cover.
In the whole observation phase, test region co-falling water 377.2mm, the sediment charge of runoff yield situation and runoff sees Table 1.
Table 1 different disposal water and soil loss total amount relatively
As seen, stalk covering and ridging plastic mulching benefit are obvious, and plastic mulching is also played certain control runoff and reduced the effect of radial flow sediment content.
The invention provides a kind of hillside fields corrosion inhibitor methods of cultivation with low cost, simple to operate.
The field stalk covers, and can effectively prevent the generation of rainwash, and stalk has the effect of water-absorbing-retaining.
Plastic mulching can be protected topsoil, prevents that runoff from washing away, and can promote surface water.
Secondly the ridging plastic mulching can prevent the generation of runoff effectively,, can effectively keep moisture, the 3rd, can effectively prevent top layer evaporation of water behind the ridging, and promote top layer moisture.
Stalk is big at the rural area amount, obtains easily, and stalk covers not only has the steady temperature effect of good water conservation, has realized the recycling of agricultural wastes again, the effect that has more fertilizing soil and prevent erosion.Secondly, that mulch film has is airtight, light transmission good and heat water conservation significantly and precocious production-increasing function, uses extensively in the farmland, and annual consumption is big.And different the covering combines with different tillage control measures, more helps the water and soil loss of ploughing in the anti-slope of harnessing the river.The 3rd, the ridging plastic mulching belongs to a kind of of little catchment growth technology, and is simple to operate, and it is convenient to utilize.
Embodiment 2
In the slope of 15 °～20 ° of the gradients, stalk covers 4500kg/hm
2-5500kg/hm
2, the high 50cm in ridge.All the other steps are identical with embodiment 1, repeat no more.
Embodiment 3
At the slope of 20 °～30 ° of the gradients, stalk overlay capacity 5500kg/hm
2-7500kg/hm
2, the high 50cm in ridge.All the other steps are identical with embodiment 1, repeat no more.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
