Citrus garden is covered with grass in summer
According to our experiments in recent years, the orange grass cover in summer can effectively exert the comprehensive effect of improving soil fertilization, water storage and drought resistance, temperature and heat insulation, and preventing fruit drop, significantly improving citrus quality and yield, and increasing the yield by 10%. %the above. However, the citrus groves have high requirements for technology, and the methods are not effective. To this end, we will discuss the main points of grass-covering technology in combination with practice. 1, suitable cover time. Usually before the arrival of the drought, it is advisable to cover the grass after fully cultivating and cultivating the soil in the garden after the rain. In winter and spring, the grass can be turned into the ground. The time should not be too late. If the drought has already arrived, then the grass will be effective. However, the functions of adjusting water, fertilizer, gas and heat will be relatively weakened and will not reach the best effect of grass cover. 2, suitable way of covering grass. The way of covering the grass in the citrus groves depends on the source of grass. In areas where there are sufficient grass sources, the whole garden will be covered with grass. Conditional orange orchards, wheat straw, corn stalks, weeds, straw, bean stalks, green manure, shanqing, etc. can also be crushed and mixed with soil and fertilizer to cover the whole garden. Where there are insufficient grass sources, the quality of the grass should be guaranteed, and how much it can be covered. It cannot be covered only by the tree. After the grass is covered, the soil blocks shall be sown to prevent the wind from blowing grass. 3, suitable thickness of grass cover. The thickness of the entire garden is about 10 to 20 cm. The young orchard is thicker and thicker. The mature orange orchard is more thin; the garden is thicker and the garden is thinner. The general mu need grass the most 60 ~ 80 Tam. If the amount of grass is not enough to cover the tree plate, the thickness of the grass layer must reach 20 cm. 4, attention. After the orange garden is covered with grass, if the ditch is not smooth, once it meets with continuous rain, the permeation and permeability of the garden soil will be inhibited, and in serious cases, it will not cause rot. Therefore, pay attention to clean up the ditch. If grass cover is not enough, it can be properly watered. Before the pests and stalks are covered, they should be exposed to the sun for 2 to 3 days, or be sterilized with lime water to kill the pests.
