Just recently we have compiled a method for deep-turning soil reforms in mountainous hills orchards. Next, we will talk about the techniques of deep-turning and changing soil in low-mountain hills orchards, and deep hills and orchards to deepen the soil. First, we should understand the roots of fruit trees. Distribution of the situation in order to scientifically manage the soil. Let's take a look at it together. 1 deep turn period The deep-turning period has a great relationship with the effect of deep-turning the soil. If the deep-turning period is not appropriate and the technology is unreasonable, it will cause poor growth and delay the saplings. Apples, pears and other fruit trees are suitable for deep-turning before and after harvesting of autumn fruits, that is, after harvesting of early and middle-ripe varieties, the mature varieties are combined with the application of base fertilizer before harvesting. Because this is the time of rapid growth of the roots, deep roots help to heal the roots and promote the release of a large number of new roots. At this time, the new shoots in the shoots grow slowly or stop growing, and they are in the stage of accumulation and accumulation of nutrients in the tree. At this time, the deep turn is beneficial to the absorption and accumulation of nutrients by the fruit trees, laying a good foundation for the next year's growth. If it cannot be deeped before the leaves due to time and labor, it can also be combined with green manure or other fertilization for partial shallow deep turning in June-July of the second year (1/3 to 1/2 of the annual tree turning) ). Deep down every year can alleviate the problem of insufficient labor, and at the same time avoid too many injuries at one time. In addition, if you need to deepen the spring in the actual operation, you should pay attention to irrigation and drought prevention, and pay attention to drainage and flood control in the summer and autumn. 2 deep depth The depth of deep-turning soil in low hilly orchards should be determined according to soil properties and root distribution. Generally, the lower layer of soil may be less solid, and the lower layer of soil may be more viscous or have an impervious layer to break through the impervious layer. If the lower layer of the mountain orchard is semi-weathered mother rock, coarse sand or gravel, it should not be too deep, so as to avoid leakage and leakage. The deep turning depth is generally 40 to 50 cm, and the condition is preferably about 1 m. When deep turning, sand can be mixed according to the soil of the orchard (clay ground) or soil (sand land). 3 Protecting the roots Deep roots in the orchard are inevitable, but the number and extent of root damage should be minimized when deep turning. Avoid mechanical damage when handling, pay special attention not to damage the main root. For the rough roots that are inadvertently damaged, it is necessary to cut the wound and promote healing to facilitate the birth of new roots. 4 Add fertilizer At the same time, it is necessary to combine enough organic fertilizers. The addition of organic fertilizer can significantly improve soil structure and physicochemical properties, and promote the formation of aggregate structure. The soil becomes loose and loose, and it can enhance the ability of ventilation, water retention, fertilizer retention and water retention, improve fertility, and promote the growth and development of fruit trees. The fertilizer should be finely divided and applied to the root group distribution layer of 30 to 40 cm below the ground. After fertilization, pay attention to the fertilizer and soil, and avoid burning the roots. 5 deep watering Immediately after deep turning, the water should be filled, and the irrigation should be sufficient to restore the roots and promote the roots and soils to promote root development. This measure is especially important for orchards that are deep in winter and spring. According to the investigation in Huangjiashan Village, Guojiatun Town, Yutian County. In the case of spring drought, the rate of dead roots after turning over without water is much higher than that of not deepening, and the rate of dead roots is significantly reduced when water is poured after deep turning. Practice has proved that as long as these technologies are mastered, they can generally play a good role in deepening the soil. From the second and third years after deep turning, it can show the effect of promoting the growth of new shoots and increase fruit yield.
