Biohedge technology refers to the planting of perennials that are drought-tolerant, tolerant, dwarf, and well-developed root systems along a slope (middle-upper) of contour lines or orchard terraces along the slope of a slope. Shaped retaining belt, using its solid foundation to retain water. Through the application of related technologies such as planting biological hedges and biological coverage, it can effectively reduce soil erosion and evaporation of soil moisture. It is a new agronomic and water-saving technology to improve the efficiency of natural precipitation in slope orchards. 1. Create a hedge. In the dry slopes or slopes of orchard terraces, biological hedgerows are planted according to different slopes, slope lengths, slopes and rainfall, and a hedgerow of 1 meter wide is created for every two steps of the slopes. band. Biological hedgerow varieties are best to use a certain economic income of plant species, such as Guimu 1st, mulberry, day lily, pigeonpea, tea tree, alfalfa and so on. The planting specifications can be based on the characteristics of the species of the hedgerow, with 1 to 3 rows of intervening species and a plant spacing of 20 to 25 cm. The selection principle of economic hedgerow varieties is as follows: 1 perennial plants, preferably herbs, vines, and shrubs; 2 strong sprouting power, good recovery; 3 well-developed root systems with high leaf-stem ratio; 4 strong anti-stress, especially Requires strong drought resistance and waterlogging resistance; 5 Good biodiversity and ecological diversity; 6 High ecological benefits and certain economic benefits. 2. Build narrow terraces and implement contour planting. The new slope orchard should be built with a narrow terraced land, so that the ladder surface is slightly inclined inwards, and the slope surface of the terrace must form a certain slope in order to plant a hedge on the slope surface. Planting fruit trees on the ladders to form contour lines and planting biological hedges on slopes will allow rainwater to seep on the ground and reduce soil erosion. 3. Undergrowth biological coverage. Planting cash crops among fruit trees, including red flowers, scorpions, mung beans, soybeans, peanuts, etc., can also keep some useful wild herbs and vines to cover the ground and keep the soil moist. 4. Benefit Analysis. After many years of experiments and demonstrations, the biological fence technology model has the following significant benefits: 1 The ecological benefits are good. The first is to reduce soil erosion. Water and soil monitoring data show that the application of biological hedges and contour planting technology integration reduces surface runoff by 21% to 22% and can significantly reduce soil erosion. The second is to improve the ability of soil water storage and soil conservation, and the soil moisture content can increase by 4%-6% under drought conditions. The third is to improve the efficiency of water and fertilizer utilization. The test results in the Youjiang River Valley and the demonstration areas in Suining and Pingguo show that the water retention rate of soil moisture increased by 9.8%, and the fertilizer utilization rate increased by 6.1%. , 2 significant economic benefits. The first is less investment. Planting hedgerows and contour planting, the investment of 50 yuan per 667 square meters of seedlings and labor costs is less than the investment in wall-building soil conservation projects. The second is high efficiency. The integration of high planting techniques, such as sloping land hedges and gentle slopes, can increase fruit production by 100 kg per 067 square meters and increase production value by more than 200 yuan. The third is to expand the space for farmers to increase income. The use of economical hedgerows planted on orchard walls and legume green manures planted between rows of fruit trees will increase income by around $50 per 667 square meters, in addition to maintaining soil and water conservation. frozen monkfish skin on Monkfish Skin On,Frozen Monkfish Skin On,Fresh Monkfish Skin On,Fresh Frozen Monkfish Skin On Zhoushan Junwei Aquatic Products Co., Ltd. , https://www.junweiaquatic-intl.com
