Orchard has many advantages over spring straw

Orchard straw mulching is a soil management technology that is applied to orchards with thin soil layer, low fertility, poor water conditions, and large soil exposed area in hilly and mountainous regions. After years of in-depth research on soil and fertilizer stations in Shandong Province, a relatively mature technology model has been established. Widely promote the application of production. The technology is to cover the bare soil around the fruit trees with a suitable amount of crop straw. It has many effects such as fertilization, water conservation, heat preservation, grass weed control, no-tillage, labor saving and prevention of soil erosion, etc. It can improve soil ecological environment, grow roots and trees, promote tree growth and development, and then increase yield and improve quality. This technique is suitable for use in semi-humid semi-arid and arid regions and is not suitable for clay orchards with poor ventilation and low-lying orchards with poor drainage. The precautions are: Coverage should be around the beginning of May in the spring after soil temperature rises, or in autumn after the wheat harvest. Do not cover during the spring soil temperature rise. Do not cover the grass within 40 to 50 cm around the roots. Orchard cover should be carried out on the basis of deep plowing and soil improvement, and a certain amount of available nitrogen fertilizer should be applied. Covering the orchards must have a good drainage system to prevent excessive humidity in the rainy years, affecting root development and fruit tree growth. After the straw is covered, due to changes in the ecological environment, the pest population and its occurrence patterns will also change accordingly. Therefore, the orchards should be systematically forecasted and forecasted, and comprehensive control measures should be formulated.
