Sweet orange winter tube and tree increase income
"At present, the fruit has not yet been picked. It is necessary to timely bury the rotting fruit on the tree or on the ground and avoid the infection of germs..." December 6th, 10,000 mu of sweet oranges in Daqiangkou Town, Naxi District, Chenzhou City At the base, Liang Mingcai, a technical staff of the Minfeng Orange Cooperative, is directing fruit growers to carry sweet orange winter tubes.
Fertilization tips
"Sweet orange orchards can be used to supplement the basic fertilizer in winter." Liang Mingcai said that composting compost, ring fertilizer, green manure, crop straw, and manure, chicken manure and other organic fertilizers are all good choices. The application amount may be 2-3 kg of fertilizer per 1 kg of fruit produced, or 15-20 kg of organic fertilizer per adult fruit tree. The organic fertilizer must be fully cooked. If the organic fertilizer is not directly applied to the soil, it will produce a lot of heat and cause burn-out.
We should fertilize the trunk as the center, and dig 4-6 pieces of radial pipe trenches that are narrow and wide and shallow inside and outside, and are generally 20-40 centimeters deep and 40 centimeters wide. , about 80 cm long. Trenches with a diameter of 1.5 cm or more are encountered during trenching. Try not to cut them. Keep in mind that the applied fertilizer must be well-mixed with the soil and watered with appropriate amount of water before covering.
Fruit trees have little demand for trace fertilizers, but they are indispensable. When the supply of certain trace fertilizers is insufficient, the fruit trees are susceptible to physiological diseases such as deficiency of hormones. For example, iron deficiency can cause yellowing disease, and zinc deficiency can cause lobular disease. For fruit trees that have iron deficiency performance all year round, ferrous sulfate is added to the base fertilizer, but the direct application of ferrous sulfate into the soil will quickly turn into insoluble compounds, so it is better to apply the organic fertilizer at the same time. For perennial orchards lacking boron and zinc deficiency, each year the base fertilizer is applied with boron and zinc fertilizers by means of ditching and hole application. Generally, each adult tree is put into 50 grams of boron fertilizer and zinc fertilizer.
Trimming with exquisite
Liang Mingcai said that when entering the rich oranges, the five or six root shoots on fruit tree twigs should be erased and the long shoots should be removed. At the same time, a part of the old branch is too old, which will increase the light and avoid the growth of the tree. It is more difficult to pick.
Pruning should respect the “tree rightsâ€. As a result, the tree will only cut dry and dry branches, serious pests and branches (especially those with heavy leaf blight damage), crossbred branches with no use value, old thorns, and short cuts that cannot be changed. The late autumn shoots of yellowing should be cut or cut off. The resulting tree was trimmed appropriately after the fruit was harvested. Note that you must not cut off the results of the second year of the twigs, try to retain the middle and lower branches of the canopy, so that less cut, light cut, more pull branches, make it a reasonable distribution, uniform branching, forming a natural happy shape to Increase the photosynthesis of fruit trees.
According to Liang Mingcai, the number of main branches retains about 20 fruit trees, which can be trimmed into slender spindles; the number of main branches remains at about 10 fruit trees, and they can be cut into free spindles. Any tree shape is a good tree shape. The trees are airy and light-transmitting, tree vigor is strong and healthy, and annual yields are on the line.
Special remind to teach you a few tricks to prevent freezing
Liang Mingcai said that sweet oranges are semi-dormant in winter, and their ability to resist cold is weak. Therefore, we must pay attention to the winterization and antifreeze of sweet oranges in winter. Pay attention to the following links:
Coverage: The arrival of cold winter use different coverings (such as straw, straw or shade net, thin waste film, etc.) to cover the roots of fruit trees to prevent nighttime ground temperature radiation, in order to increase the surface temperature of the roots of fruit trees. Hang fruit trees and cover the trees with a thin film to prevent jelly cracking, affecting yield and fruit shape.
Earth-cultivation: Earthing can thicken the soil layer, inhibit the evaporation of soil moisture, increase soil temperature, and raise the soil height to not exceed the grafting interface. After the frost period in the next spring, the soil should be split and the roots should be protected from decay.
Winter irrigation: In the orchard with irrigation conditions, water should be promptly irrigated 3-5 days before the onset of the cold wave. It is advisable that the amount of water in the orchard be as long as 10-15 cm. Irrigation should be carried out at a high temperature at noon. The water should be thoroughly irrigated, then drained after irrigation, and cultivating in a timely manner to prevent freezing after irrigation.
Smoke fumes: Thick frost tends to freeze sweet oranges, especially if the frost falls after freezing. Therefore, according to the weather forecast, smoke can be used to radiate heat, reduce frost, smoke, smoke, smoke, can use chaff, sawdust, defoliation, straw, etc., 4-6 heap per acre, lit before the onset of low temperatures.
At the same time, the main trunk can be painted with 30% - 40% lime solution, and the ground plant and the rootstock can be grafted to the soil and the soil pile should be 30cm or more high.虬 嗤 嗤 嗤 嗤 跚 跚 跚 跚 跚 跚 跚 ┙ ┙ ┙ ┙ ┙ Τ Τ Τ Τ Τ Τ Τ Τ Τ Τ Τ 跚:
