- Abstract:
- In order to further explore the physical and chemical properties of grey brown desert soil under different tillage measures in the main wolfberry production areas in Qinghai, scientifically evaluate the comprehensive soil fertility in arid areas and improve the ecological and economic benefits of the wolfberry production areas, an experiment was conducted to study the soil under the different tillage measures in the main production areas of Qinghai, and the flat land and bare land was used as the control. The soil granule composition and soil nutrient of gray-brown desert soil were studied under ridge planting and mulching treatment. The improved Nemero comprehensive index method was used to analyze soil comprehensive fertility. The results show that:(1)the soil in the study area has a high sand concentration, and the sand content ranges between 61.44% and 85.59%; content of soil sand decreases by 39.31% under the mulch film treatment compared with the control treatment;(2)the soil in the study area shows the high pH value, average potassium, and the insufficiency of organic matter, nitrogen and phosphorus; from the vertical direction, the soil nutrient index decreases with the increase of soil depth; the results of different tillage measures show that the nutrient indicators are higher than other treatments except for available phosphorus and pH value; the improvement effect of the furrow and mulch film is more obvious; the coefficient of variation of soil nutrient index is between 4.27% and 50.81%, among which the coefficient of variation of pH value is the smallest, the amount of available nitrogen is the largest, and the coefficient of variation of available nutrients is greater than the coefficient of variation of the corresponding total nutrient;(3)the comprehensive evaluation values of soil fertility decreased in the order: ridge-furrow and film cover>flat land and film cover>ridge-furrow and bare land>flat land and bare land. In the unique climatic conditions of the test area, the improvement effect of the mulch measures compared to the open field planting is better than that of the ridge ridge measures compared to the flat planting. Among them, the mulch treatment increases the soil comprehensive fertility index by 43.33% compared with the control treatment. Therefore, in the main wolfberry production areas of Qinghai, the furrow and mulch film planting patterns not only have the effect of reducing the erosion, but also are more conducive to the soil conservation and fertilizer conservation, and should be promoted.
