How to manage autumn or winter mountain orchards
First, the soil management in autumn, deep-turning the soil, increasing the roots of the lower grassroots, but also to promote the occurrence and growth of autumn roots, enhance the ability of resistance to cold, the depth should be determined based on the depth of the soil and tree roots. Second, rational close planting In the absence of water in mountainous orchards, reasonable and close planting will allow fruit trees to obtain sufficient water and nutrients to achieve high quality and high yields. Generally medium-density plants are planted at a spacing of 2.50 to 3 meters and 4 meters, and the garden is as flat as possible. Tai Hang (1 meter square) planted. Third, increase the input of rational fertilization, increase organic fertilizer, change nitrogen fertilization habits, implement formula fertilization, enhance tree vigor, and improve fruit drought resistance. In the Loess Plateau region, precipitation in autumn is relatively high and soil moisture is high. The timely use of base fertilizer is beneficial to the storage of nutrients in the trees. Even if the spring drought occurs this year, the trees will have more nutrients for storage, which will enable the trees to grow robustly and have large leaves. The fruit setting rate is high, and the drought resistance is enhanced. Fertilizer should be suitable for reasonable deepening to induce downward root growth and enhance drought resistance. 4. Pruning The pruning of fruit trees is divided into dormancy trim (winter shear) and growth trim (summer shear). The main effect of winter pruning in regulating growth and conflicting results is the rational formation of three types of shoots in the canopy, ie growing branches, forming flowering branches, and resulting branches. V. Pest Control 1. Clean the fallen leaves and dried fruits in the ground. In winter, the fallen leaves, weeds, and fallen fruits and dry branches are cleaned and buried as deep-rooted or burned. 2. After the harvested grass rings are harvested, the grass rings are attached to the trunks. The pests on the trees are overwintering; the pests on the trees can be trapped into dormancy in the grass ring, and in December the grass rings are concentrated and burned. 3. Cut off pests and branches Many pests and diseases cause wintering on branches or diseased fruits. Therefore, combining pruning, eradicating the disease source, and lowering the number of insect populations will greatly reduce the damage in the coming year and even eliminate some pests during the overwintering stage. 4. Properly scrape the trunk of the trunk. Many pests and diseases cause wintering on the trunk. Therefore, the rough skin on the branches should be scraped off in winter so that the insects lurking under the skin for winter can be exposed and frozen to death. 5. Insect plug holes are stuffed with 80% dichlorvos emulsion 5 times viscous cotton balls into the hole and sealed with mud to kill worms. 6. The spraying and prevention of lime sulfur has the effect of preventing and controlling the annihilation of all kinds of diseases and pests of fruit trees. Especially after the leaves of fruit trees are defoliated, the control effect is better when the branches are completely exposed. Spraying is done from top to bottom, from inside to outside, the spray is fine spray, the whole plant sprayed. 7. The use of farmyard fertilizer must be decomposed. There is no farmland manure with lots of eggs, and it is easy to cause fruit tree diseases and insect pests. SICHUAN UNIWELL BIOTECHNOLOGY CO.,LTD. , https://www.uniwellbio.com
