Detailed Explanation of the Key Points for Daily Care and Management of Plum Trees
We all know that plums are the fruit borne by plum trees. During the planting process, it takes a lot of time to manage them, and the main thing is to do a good job of their daily care. The branches of plum trees grow very fast, so pruning is a relatively important step for them. In addition, fertilizer and water management and other care measures should be strengthened. So now let me explain it in detail for everyone!
I. Pruning of Plum Trees
The key point in pruning plum trees lies in their short fruit branches, because their flowering and fruiting are mainly based on short fruit branches, so pruning of short fruit branches should be emphasized. In the first year, the focus is on shaping the tree form and controlling branch density to ensure a perfect overall plant shape. By the time they enter the fruiting stage, attention should be paid to pruning side branches and main trunk branches so that more short fruit branches grow and the fruiting cycle is shortened. In addition, overly dense branches should be pruned, and the branches and trunks should be pinched in time to promote flower bud differentiation.
II. Fertilizer and Water Management
1. After fruit harvest and pruning are completed, the trees should be topdressed. Especially after fruit harvest, re-fruiting and branch regrowth consume a large amount of nutrients, so we should dig trenches in the field, apply decomposed manure and elemental compound fertilizer in the trenches, and then water thoroughly.
2. Fertilization is mainly applied to the leaves, and then spreads through the leaves. Of course, environmental influence also accounts for a large factor. If the temperature is high and light intensity is too weak, the leaves will become very brittle, so applying fertilizer to the leaves can make the leaves thicker, larger, more capable of absorbing fertilizer, and their photosynthetic intensity will also be greater, producing more substances beneficial to the plant. In the early stage of plum trees, mainly apply multi-element compound fertilizer with amino acids as the main element to supplement various nutritional needs. Spray once every week, and results can be seen after spraying for one month. When midsummer arrives, it can be switched to fertilizer mainly based on potassium dihydrogen phosphate.
3. At the end of summer, base fertilizer should begin to be applied to prepare for autumn. For the base fertilizer, choose high-quality organic fertilizer as the main type, apply enough at one time, then water to dilute it. There is nothing special to note about watering. Plum trees also have relatively strong cold resistance, so basically follow normal watering, but prevent waterlogging. Sometimes when there is a rainstorm or too much water is accidentally applied, water accumulation occurs, and these are all things that need attention.
4. Then there are the methods for preventing and controlling pests and diseases that plum trees may have. After pruning and fruit harvest, plum trees should be sprayed once with insecticide and fungicide. Insect control is mainly aimed at mites, and acaricide can be used to kill mites. In addition, carbendazim can be used for sterilization, which everyone knows. Also, bacterial shot hole is a disease that tends to prevail in June, and some pests and diseases such as red spiders, stinging moths, and brown rot should all be noted. Once discovered, carbendazim, acaricide, and thiophanate-methyl powder can be used alternately, which can achieve a very high control effect. Early discovery and early prevention and control should be achieved.
5. To promote flower bud differentiation, paclobutrazol wettable powder can be sprayed on the plants in June, and then spraying can be carried out according to the actual growth situation afterward to control the nutrients needed for growth. In late November, high-quality urea can be sprayed on plum trees to force leaf fall. It takes effect after three to four days of spraying. Doing so can shorten the time for covering the shed.
The above are the key points for daily care and management of plum trees. Have you all learned them? Daily care of plum trees includes the two major points of pruning and fertilizer and water management. There is nothing else. Doing these well can basically allow them to fruit smoothly. At the same time, pay more attention to pests and diseases, because their occurrence has a great impact on growth. If you want to learn more related knowledge, please continue to follow Qinnong Web!
