Heavy rain consequences tree how to control
In the summer of this year, heavy rains hit various parts of the country, and floods occurred in many places. For fruit tree production, locust plague will cause yellow leaves, rotted roots, poor flower bud differentiation, and rapid pathogen infestation. Fruit growers should attach great importance. The possible problems and management measures of the heavy rain consequences tree are summarized below for reference. Clean up the orchard to remove debris, residual leaves, and residual fruit in a timely manner, bring deep burial outside the park, and reduce the occurrence of diseases. After the branches of the newly planted orchard were broken by heavy rain, they should select proper germination and appropriate retraction to promote new shoots. Spraying to protect fruits, leaves, branches and trunks is susceptible to various types of diseases. After the disaster, it is necessary to spray the fungicide thoroughly and thoroughly. The whole garden is sprayed with 30% thiophanate-methyl 1000 times solution + 0.3% potassium dihydrogen phosphate solution, 3% multi-resistant antibiotic 500 times solution + tree ankang 800 times solution + green Fenway No. 1 1500 times, 43% tebuconazole 4000 times + amino acid fertilizer 500 times, 68.75% Yibao water dispersible granules 1000 times, 10% Shigao water dispersible granules 2000 times, 80% Manganese zinc wettable powder 800 times, 90% thiophanate-methyl wettable powder 800 times liquid +4% agricultural anti-120 water agent 800 times liquid, spray once every 15 days, even spray 2 or 3 times, and Note alternate medication. After the fruit trees in the supplementary nutrient suffered a disaster, the tree tends to become weak and the ability to resist disease declines. To restore the tree potential as soon as possible, nutrition must be added in a timely manner. Combine spraying on trees, spraying foliar fertilizers, spraying 50 times urea, 350 times potassium dihydrogen phosphate, and amino acid foliar fertilizers, etc.; The results of tree topdressing quick-acting compound fertilizer 1 to 2 kilograms, saplings per tree topdressing special compound fertilizer 0.5 to 1 kg. Young fruit is often covered with hail during rainstorms, and young fruit with only slight epidermis is retained as much as possible, but bagging management is not recommended. For undamaged young fruit, the whole garden should be sprayed with 1 to 2 times of fungicide. Then fruit bagging. Consequences of loosing soil torrential rain results in soil compaction and poor permeability, affecting the growth of fruit tree roots. Therefore, when the topsoil of the garden is to be dried, the soil is loosened in time to increase the permeability of the soil. Low-lying land should do a good job of drainage work to create a good environment for the growth of the root system. Prevention of yellow leaf rain on fruit trees can provide sufficient moisture for the growth of fruit trees, but it often results in oversupply of major nutrient elements and insufficient supply of some directly related elements in the minimum nutrient law, resulting in different degrees of yellowing of the leaves. Therefore, after rain, pay attention to the combination of underground topdressing and foliar spraying, paying particular attention to the application of iron and boron, magnesium, zinc, and other trace elements. At the same time, paclobutrazol 150 times solution or PBO 250 times solution can be applied to over-prosperous trees to control their growth. Anti-fruit tree rotten root individual plots of low-lying land, resulting in short-term accumulation of water, root anaerobic respiration of fruit trees, resulting in some roots rooting, affecting nutrient supply, resulting in short-term rapid wilting of leaves, and rot and other diseases. Mushi Lime 100 kg can be turned over, combined with fertilizer plus 6000 times love over 300 ~ 500 times liquid sterilization. To promote flower bud differentiation is currently the fruit tree flower bud differentiation period, heavy rain will make most fruit trees prosperous, affect the vegetative growth to reproductive growth transformation, resulting in flower bud differentiation nutrition and fruit trees prosperous nutritional competition, resulting in poor flower bud differentiation, affecting yield. It is necessary to prune through the summer, remove excessive back branches or pull branches, adjust the tree vigor and coordinate the supply of nutrients. At the same time, the combination of spraying foliar fertilizer such as 0.3% potassium dihydrogen phosphate solution and growth inhibitors promote flower bud differentiation.
