Orchard-covered grass can create a good environmental condition for the growth of fruit tree roots and even the entire tree body. It is an important technical measure to achieve high quality and high yield in dryland orchards.
First, the advantages of orchard grass
Grass cover improves the physical and chemical properties of the soil. Grass-covered orchards have changed groundwater, gas, and thermal environments. The change of soil temperature is relatively stable. In summer, when the soil temperature reaches 5 to 10 centimeters and the temperature reaches 34.5°C, the soil temperature at the grass cover is 24°C. Increased soil moisture, high fertility, and rapid microbiological reproduction. After testing, the soil moisture content in the 20 cm soil layer of the Leucao Garden was increased by 4.3% to 8% compared with the non-mulching grassland, and the soil organic matter content was lower than that of the non-mulching grass orchard. Increase 20% to 30%. Good soil pellet structure makes the fertilizer effect sustainable for 2 to 3 years.
Grass cover promotes the growth and development of the tree. The increase of soil moisture and a large number of activities will loosen the soil and increase the absorption of roots in the shallow soil layer. The roots of the fruit trees will be more developed. The differentiation of flower buds will be promoted. The spring flowering period will be neat and the petals will be thick and thick. The diameter of the crown is 5% to 10% higher than that of the Qinggengyuan, and the yield is about 20% higher than that of the Qinggengyuan.
Reduced grass and insect pests and improved fruit quality. Orchard grass can reduce the water transpiration, inhibit the growth of weeds, control soil erosion, reduce orchard pests and diseases, increase the coloring of bagged fruit and reduce cracks, ensure fruit quality and high yield.
Grass cover improves the economic benefits of fruit trees. The cost of the grassland covering the grass is 100 yuan per mu, and that of the fruit tree in the full fruit period is calculated as 200 kg per mu. The income per mu is increased by about 400 yuan, and the input-output ratio is 1:4. Grass-covered orchards are low-input, high-output, simple, and cost-effective measures for dryland orchards.
Second, orchard grass cover method
An orchard that is confined and not intercropped should be covered with grass, and young orchards should be partially covered with grass (tree or tree line). The crop stalks or orchard weeds are crushed and evenly spread between rows of orchards and under tree trays, with a thickness of 15-20 cm. In the grass, stars are pressed slightly to prevent wind blows and fire. The thin layer of orchard can be a combination of trenching and grass cover. After 3 to 4 years of continuous ploughing, the basal fertiliser is applied once again, and it will be repeated the next year.
Third, several issues that should be paid attention to when covering grass
Grass cover time. All year round, it is advisable to carry out the spring season, wheat harvest, or harvest season with rich grassland. The dry and thin lands are mostly covered when the temperature of 20 cm soil layer reaches 20°C; Weeds, leaves, crop stalks, and chopped firewood are all acceptable. Spring covered hay and summer pressed grass. Partial grass cover with 1000-1500 kg of hay per acre, fresh grass is generally 2000-3000 kg; the whole garden cover grass is 2500-4000 kg. The grass should be short so that it can be covered and rotted; The tree tray covers the grass to cover the root distribution (outer canopy); Before mulching grass, combined with deep turning or deep watering, apply 0.2-0.5 kg of nitrogen fertilizer to meet the requirement of microbial decomposition of organic matter on nitrogen fertilizer; After the fall, the grass-covered garden should be shaved after the autumn. When applying the basal fertilizer in the autumn, do not put the grass cover into the ground. The grass should be stamped every year or every other year. 4 to 5 years deeper, turn over and cover the grass. When topdressing, you can open the cover grass, apply more points, apply proper amount of water after the application, and strengthen the fire protection. During the winter and spring dry season, pay attention to the fire protection of the orchard.
