Yang Meidong's neglect of control
Winter management directly affects the production and quality of bayberry in the following year. Like other fruit trees, Yangmei’s winter management is mainly in clear gardens, especially under the atmosphere of warm winter this year. The specific contents of Yangmei's winter management are now described as follows:
1. Trim the normal result tree that has not been reshaped, first open the small skylight, that is, delete the top upright branch 1-2, and then “small adjustment inside and outsideâ€, that is, delete the diseased leaves, insect branches, leaves , dead branches, stumps, and weak branches, remove the dense branches, erect branches, and overlapping branches in the crown, cut off the squidless branches of the crown, the late autumn shoots, and the branches of the two trees, and the lower drag branches. In principle, the branches on the upper part of the canopy are “strengthened and weakened†and the lower part is “trimmed and weakenedâ€.
For a normal result tree that has been reshaped, as long as the branches and branches, dead branches, stumps, weak branches, cross branches, dense branches, overlapped branches, and mowed branches are cut off, the rest of the leaves are left as much as possible to ensure the tree. Produce enough photosynthetic product.
For juvenile bayberry, pruning should begin from the 3rd year. About 40 centimeters from the ground, the appropriate main branches in three directions are left to promote the deputy main branch, expanding outwards year by year. Crowded and dragging the branches in the lower part of the ground should be promptly cut off; the branches that are oblique on the periphery should be left well or pulled branches and branches to promote oblique life, in order to increase the effective photosynthetic area and make the tree body The light is good.
The annual pruning time of Yangmeishu is appropriate in December of each year. After the pruning, the branches and leaves should be removed to the outside of the park in a timely manner, especially for diseases, insects, and stubs.
Second, fertilization For each of the normal results of Yangmei adult tree, every winter should be applied into the cake cake fertilizer 2-3 kg, 25-25 kg of plant ash, borax 50-100 grams. Yangmeishu should promote winter application of spring fertilizer so that the nutrients can be slowly absorbed by the tree body, enhance the safety of the wintering of the tree, and can promote the early spring sprouting of the following year.
Third, plus custom soil in the winter season under the canopy of the red earth, can increase surface temperature and humidity, enhance root absorption capacity. The best soil for the earth is the yellow mud soil under the wolverine. Before adding the soil, the landing branches and leaves under the canopy should be cleaned, or sprayed with lime sulfur.
4. After the pruning of the Qingyuan Garden, the Yangmei Garden should be cleared up in time to prevent the occurrence of a large number of diseases and insect pests in the following year. In particular, serious gardens such as brown spot, cancer, celebrity disease, and scale insects occur. Qingyuan agents can use Baume 3-5 degrees lime sulfur agent. When spraying, both sides of the trunk and the leaves must be sprayed. The number of sprays depends on the degree of occurrence of the pests and diseases, and it is usually sprayed 1-3 times.
Lime sulfur can be prepared with 2 parts of sulfur powder, 1 part of lime and 10 parts of water. First boil the water with an iron pan, then add the sulfur paste made with warm water, stir and continue to heat, then gradually add the massive lime to continue stirring, about 40-50 minutes cooking, when the liquid changes from yellow to soy sauce (deep When the brown-red color ceases, the residue is filtered off and the stock solution is filtered. During the tanning process, the water should be continuously heated to replenish the evaporated water so that the water can maintain its original volume. In order to ensure the quality of the liquid, lime should be used in the form of massive, white, and unabsorbed quicklime; sulfur powder should be fine; when tanned, sulfur should be put first and then lime. Do not use iron, copper, aluminum and other metal containers to store the liquid, it is best to use pottery, and add a layer of oil on the liquid surface (oil, diesel, kerosene can be) to isolate the air. Diluent should be used with it.
