2.1 ຄໍາອະທິບາຍສັ້ນຂອງ ເຕັກໂນໂລຢີ

ການກຳໜົດຄວາມໝາຍ ຂອງເຕັກໂນໂລຢີ:

Belts of shrub or grass, planted on the level bund which constructed along contour line in gentle slope farmland in the black soil region of Northeast China.

2.2 ການອະທິບາຍ ລາຍລະອຽດ ຂອງເຕັກໂນໂລຢີ

ການພັນລະນາ:

Shrubbery buffer strip with bund(SBSWB) is a traditional technology, it is introduced by the field staff about 60 years ago who worked in the farm in Heilongjiang province.This technology with low-cost, high effectives and easy to construct, which has been widely applied in all black soil region of Northeast China (Heilongjiang,Jilin,Liaoning,North of Inner Mongolia Autonomous Region).

Purpose of the Technology: The final purpose of these buffer strips is increasing crop production by decreasing soil loss. More specific objectives include: 1)protect the land from surface erosion by cutting slope length, increase infiltration and soil moisture; 2)to prevent soil loss of gentle slope farmland by allowing excess runoff to filter through but trapping sediment; 3) through the effect of tillage and water erosion between the strips, level bund lead to the formation of forward slope terraces over time, then developing into terrace final;4) creation of opportunities for additional income by harvesting fodder(grass) production and fruits(shrub).

Establishment / maintenance activities and inputs: A construction is generally carried out in autumn of the year; plantation is made in spring of the next year. The construction in a man-machine integration mode is generally carried out step by step and from top to bottom along the contour line(s). The ladder-shaped cross section of a ridge is 0.3-0.5m in width (suitable width on the top), 0.5-0.6m in height, 1:1 or 1:0.5 in inner-side gradient and 1:0.5 in outer-side gradient.
In a construction, peel the surface soil with machine, with the peeling depth generally being 0.3m, which should be subject to soil layer depth; then haul the ridge construction plough (a kind of machine or device) with a tractor to build the ridges, consolidate the ridges through artificial slapping; Finally restore the surface soil to accomplish ridge construction. The tops of the constructed ridges should be maintained to be in a horizontal surface. The distance between two ridges in this region is generally stipulated to be 50 meters. The soil for ridge construction should be free from such sundries as gravels, tree roots and turfs.

Natural / human environment: Shrubbery buffer strip is found mainly in Northeast China, at altitudes between 700 and 1600 m. Climate there is cold in winters and cool in summers, with a monsoon moisture regime. In the area, the annual mean temperatures is from 2 to 8 °C, and the annual mean precipitation is from 500 to 1000 mm. Most of the farmland slopes are less than 7°but slope lengths mainly range from 200 to 1000m in this area.
Northeast China, the grain production base of China, or the bread basket of China, includes three provinces (Hei-long-jiang, Ji-lin, and Liao-ning) and the eastern part of the Inner Mongolian autonomous region. In 2009, 17.1% the China’s total grain production came from this region, which included 33.5%, 55.7% and 9.6% of corn, soybean, and rice, respectively. Approximately 118 million people live in this region. Grain produced per capita is over 1000 kg annually.

ຄວາມຄິດເຫັນ:

Major land use problems (compiler’s opinion): Beacuse of long slope, high rainfall intensity, freezing and thawing processes, and intensive cultivation has lead to substantial water runoff, soil erosion, and gully formation. Soil erosion has been the serious problem threatening agriculture sustainability in the region for decades.The flora of the area are very diverse.

Major land use problems (land users’ perception): Soil fertility and crop yeild are decreasing year by year.

Secondary causes of degradation: over-exploitation of vegetation for domestic use (This area is the most important grain production area in China, there is serious excessive exploitation in this area.), change of seasonal rainfall (The rainy seasons mainly focus on July and August.), Heavy / extreme rainfall (intensity/amounts) (The downpours in summer bring about soil loss.), land tenure (As the lands are owned by country or by peasant communities, the peasants are not strongly aware of the importance of land protection.), poverty / wealth (The serious gap between rich and poor)

Machinery/ tools: Spade, Spade

3 people are required to layout contour, daily labor cost for per person is 100 Yuan, so the total labor cost is 300Yuan ($48), tools fee is 50Yuan ($8).
One tractor can built 2.6 ha of ridges per day at a cost of 500 Yuan ($80). The ridges constructed should be artificially tamped, 120 people are needed to tamp the ridges in an area of 2.6ha, about 46 people for each hectare. As the daily labor cost for per person is 60 Yuan, the total expense on each hectare is 2760 Yuan($441.6), and the labor intensity is intermediate.
If shrubs are planted on the ridges, 400 shrubs are required for each 1 hectare management area. In addition, as the price of caragana microphylla in 2012 is 0.1 Yuan per one, the total cost of the caragana microphyllas per hectare should be 40Yuan($6.4).
Therefore, the total construction cost per hectare is 3650Yuan($584).

Although Certain quantity of land will be occupied and grain output will be affected in SBSWS during the early period of a construction, in the long run, SBSWS can prevent the loss of the most fertile surface soil, in addition, with the ever increased quantity of the sediment intercepted by SBSWS and as the heights of the vegetational belts increase year by year, the slope croplands will become bench terraces, and the grain output will be increased.

ຄວາມຄິດເຫັນ:

80% of land user families have adopted the Technology with external material support

Comments on acceptance with external material support: Large-area popularization of SBSWB has been achieved in the locality.

20% of land user families have adopted the Technology without any external material support

Comments on spontaneous adoption: The implementation of this measure was accomplished under the encouragement and support of the government. There are relatively few peasant households who initially take this measure. The main reason for the peasant reluctance to adopt this measure is that the ridges will occupy land and reduce arable area. They are unconscious of and do not care about soil loss, and unable to realize in the long run the harm brought about by soil loss.

There is a little trend towards spontaneous adoption of the Technology

Comments on adoption trend: The trend depands on government support
