At present, it is a hot weather. At this time, it is the peak period of pests, and it is also the best period for fertilizer and water control. According to Xiaobian, walnut trees need to control fertilizers and prevent pests and diseases at this time. The following are detailed details of the scientific management skills of walnut garden in July. . I hope that you can help the parents who plant walnuts. First, stop the topping Newly planted saplings should not be topped in spring or summer. The saplings of 2 ages and 3 ages can increase the amount of medium and short branches by the topping method, laying a good foundation for high yield and stable production in the future. Early July is the best topping period, don't ignore it. Second, control of nitrogen fertilizer In the second half of the year after the walnut planting, it is necessary to control the amount of nitrogen application, because July is the flower bud differentiation period, and it is also the period of black spot disease and anthrax fulminant occurrence. Controlling nitrogen fertilizer can make the tree stable and not mad, and promote flower bud energy. Steady and normal differentiation, and reduce the incidence of disease. Third, timely phosphorus In June, the walnut garden has not been supplemented with phosphorus, and it can be replenished in July. Phosphorus can promote flower bud differentiation, and the effect of supplementing phosphorus at the right time is significant. The young trees with the first fruit are topped with 10 kg of high-phosphorus phytonin or high-potassium eucalyptus per acre, and the result is more than 5 years old, and 20 kg per mu. Fourth, increase the application of potassium fertilizer From the end of July, the application of potassium fertilizer to walnut trees can significantly improve the yield and quality of walnut fruits. The nuts are full, fat and taste good. In addition, potassium can promote the synthesis of cellulose, which can effectively improve the plant's ability to resist pests and diseases and resist drought and cold, which is conducive to the safe wintering of plants. The high potassium dosage is generally 15~30 kg, which can be controlled according to the size of the fruit in the garden. Fifth, control the amount of irrigation In June, July and August, if there is too much watering in the walnut garden, it will seriously affect the stable differentiation of flower buds, and the production will be greatly reduced in the coming year. Therefore, it is necessary to control the amount of watering. Note: Do not water if it is not dry. Six, beware of black spot anthracnose In recent years, there have been signs of black spot and anthrax infiltration in light or heavy areas. The incidence of saplings is generally light, and the incidence of large trees is heavier. The trees with strong trees and spacious rows are less ill, and the trees are weaker. The closed garden is seriously ill. The serious garden fruit is black and fallen to the ground, and it must be taken seriously, and it should be guarded against caution, especially in high temperature and high humidity days. The star spray on the tree is 6000 times + 1000 times fine; the phenyl ether methylcyclazole 5000 times + the Luoan 3 number 1000 times, alternately used, the whole garden spray, spray fine spray, dripping water is limited. Seven, summer insects In July, the main pests in the walnut garden were red spider, black spot bud, limb moth, and yellow thorn moth. High temperature days are the breeding season of red spiders, locusts, etc., and the larvae of the larvae are biting through the fruit and entering the fruit. Therefore, the spraying must be timely. Dispensing program: 2,500 times of imidacloprid + 3000 times of anti-war + 2000 times of Longli, once every half month, the whole garden is finely sprayed. Adding 8000 times of force-enhancing silicone when dispensing can significantly improve the insecticidal effect. Eight, control the top advantage In July, the upright strips at the top of the crown can be removed in time, and the nutrients can be supplied downwards, which can significantly promote the differentiation of flower buds and increase the yield. The top of the tree is too high, and the big tree with no fruit on the top should now fall in time, so that the lateral growth of the canopy is slightly larger than the longitudinal growth. Control the top, drop the head, the earlier the time, the better the effect. IX. Treatment of fruit table secondary tips If the fruit tops go to the second and second, go to one, and you can't leave it all, and you can't completely get rid of it. Young trees, when used in winter shears, can be used as an extension head for the expansion of the head, which is conducive to rapid expansion of the crown; large trees, fruit table secondary shoots can be used as a supplementary branch of balanced branches to increase production. The unprocessed garden of the fruit side of the table is fast-moving, and the machine does not wait. X. Post-management of grafted trees In addition to Meng is very critical. When grafting, the two leaves left above the buds, the buds in the leaf mites should be removed in time, prompting the buds to get enough nutrients and germination quickly, taking one point, less than the rest. In addition to the germination, the germination near the bottom of the bud can be removed. Before the sprouting of the buds to the deciduous leaves, no matter whether the length of the new shoots is not suitable for topping, the reason is that the secondary branches that are sprouted after the topping are all autumn shoots, and the winter shears can not find a full-fledged bud that can take the lead from the front to the back. It grows slowly and it is difficult to expand the crown quickly. The management of walnut planting in July is very important, because it will start to bear fruit in July. If you do not control the fertilizer or prevent pests and diseases, it will seriously affect the yield of walnuts. You must pay attention to it.
