First, the benefits of Qiulidi soil preparation 1. Turn over the soil and turn over the topsoil. Turn over the topsoil that has lost nutrients and turn up the soil that has not yet been destroyed. At the same time, weeds and root crops can also be buried underground, reducing weed damage the following year. 2. Improve soil structure Through the autumn fall soil preparation, the soil structure can be smashed, and organic fertilizers can be buried deep in the soil. After fermentation and rot, the activity of microorganisms can be promoted, and the farmland can become a granule structure more conducive to the growth and development of crops. 3, increase the permeability of the soil Ventilation permeability of the soil is particularly important for the growth and development of crops. Fall-falling soil preparations can effectively increase the aeration and permeability of the soil. 4, reduce the incidence of pests and diseases through the fall over the soil preparation can be buried deep in the ground, suffocation and death, bacteria due to environmental changes and can not continue to survive. At the same time, underground pests can also be exposed to the surface, or they can be frozen to death, dried up, or eaten by birds, thus reducing the damage of the pests in the coming year. 5. Avoid loss of soil moisture Spring drought, temperature rises quickly, evaporation is large, air is dry, wind is windy, soil loss of spring soil is large, and fall soil preparation can effectively avoid soil moisture when the soil is turned over. loss. 6, to avoid competing with the spring planting competition in the spring when the temperature rises quickly, the spring time is urgent, spring turning may be too late. Falling the land can ease labor and avoid the time when the land is turned over and when the seeds are being contested. Second, the technical point of the autumn tipping 1. Turning early and not late, mastering the suitable tillage depth The autumn fall should be carried out as early as possible after the autumn harvest, so that there will be sufficient time for soil ripening, which will help the soil to accumulate late autumn precipitation, and establish soil tillage reservoirs to realize the autumn and winter springs. use. If the ploughing is too late, too late, it will cause the ground surface to be too much, too much, and reduce the quality of ploughing. This will not only adversely affect the soil maturation, but also affect the quality of spring sowing. 2, the fall of the soil to pay attention to soil moisture soil moisture content is appropriate, after the soil is finely crushed, to protect the well, and the small resistance of the ground, high work efficiency. If the soil moisture is too large, it is easy to form sticky strips after turning it over, and it becomes dead and waste when it is dry. Even if it is repeated for many times, it is difficult to break it and it is not safe. The soil is too dry, the resistance to turning over the ground is large, the work efficiency is low, and the quality of cultivation is poor. Autumn turn should give priority to ploughing earthy and sticky land in order to achieve loose soil and accelerate soil ripening. For the sandy soil with light soil texture, it is not necessary to turn over or use the following year for ploughing, which is more conducive to water storage and conservation, and at the same time, it can save the investment in farming operations. 3, to prevent the running water running Qiuqiu the land can be immediately land preparation, ridge and timely repression before freezing, to prevent running water running. While ridging in autumn, the implementation of autumn fertilization is a relatively effective measure to increase production. After the fall, if there is no time to prepare the site for land preparation, when the soil layer reaches 10 to 15 cm, it is possible to carry out the pressure and soil preparation. It is better not to be late as early as possible. 4. Autumn fall should be combined with autumn irrigation combined with water and irrigation conditions. After the fall, timely soil preparation should be done for autumn irrigation. Because only the irrigation before freezing can make the irrigation water infiltrate into the soil plough layer, preserve it, and achieve the spring drought and fall resistance. At the same time, it can also delay the freezing of soil, which is conducive to soil microbial activity, promote the transformation of soil nutrients, and increase soil fertility. To sum up, the autumn turning ground is the basis for planting Miao Miao Zhuang in the following year, and it is an essential prerequisite for high yield. Third, Qiu Tui Soil Preparation must be "seven to do" In autumn, it can activate the soil structure and improve the physical properties of the soil; it can extinguish the weeds and the roots of crops and fertile soil; and change and destroy the wintering environment and places of pests to kill pests. If it can be combined with autumn trespassing, it can also provide sufficient time for spring plowing production. However, it is imperative to ensure the quality of autumn-fallen soil preparations and avoid running rough. Specific attention should be paid to the following points: 1. Appropriate autumn cropping should be carried out before the soil is frozen. 2, the depth of deep autumn generally about 22-25 cm is appropriate. In the shallow black soil layer, the plough layer can be used to deepen the plough layer in order to avoid turning the underlying raw soil and sandstone into soil. 3, flat after the ground to be flat and fine, no obvious large clods. 4, Qi must turn over and turn to the side. The land and the land are neat, and the land is straight and tidy. 5, after the net roll without a stand, there is no sitting squatting, the remaining straw and roots should be rolled clean, no "hen nest" phenomenon. 6, through the autumn fall over the ground, to turn over the combination, with the turn with the flood, through the tillage, to achieve ground breaking, not leaking, not tow. 7, after the actual turning, we must take irrigation, suppression and other measures. To make the soil reach the upper Panasonic, the soil is close to moderate.
