Doing Well Winter Fruit Tubes to Improve Fruit Quality in the Next Year
After the fruit is harvested, the nutrient in the tree body is seriously overdrawn, the resistance is extremely weak, various pathogenic organisms take advantage of the deficiency, and serious damage to freezing occurs. If the winter tube is not carried out in time, it will directly affect the fruit setting rate in the next year, leading to a decline in yield.
I. Strengthen water and fertilizer management
After the fruit is picked, it is timely to supplement the tree nutrition, strengthen the vigor, accumulate nutrients, and promote flowering. Shiji fertilizer is the most important one-year fertilization for the whole year, and it is necessary to apply heavy basic fertilizer in the autumn, and it should be carried out before the soil is frozen after the fruit is harvested. Generally, it starts from mid-September. Basal fertilizer is mainly organic fertilizer, such as manure, heap excrement, green manure, crop straw, etc. If the appropriate amount of available nitrogen fertilizer and phosphate fertilizer is added, the effect is better. When applying, mix fertilizer and soil well and apply adequate water.
Second, thermal insulation
Into the autumn and winter season, the weather turned cold, the fruit tree metabolism is relatively slow, vitality is weak, it is difficult to withstand the harsh environment. In order to enhance the ability of fruit trees to prevent and resist adverse environmental factors such as cold and frost resistance, it is possible to spray “new high-fat film†emulsions to effectively protect the fruit trees from cold, frost, disease, and corrosion, and to suppress the reproduction of pathogens and restore plant vitality.
Third, the end of autumn control
For the southern fruit trees, the critical period of flower bud differentiation is from late October to early November. The main task is to control the tip and promote flowering. Use a blunt blade to cut deep into the xylem at the smooth part of the trunk, smear “promoting Huawang No. 2†to prevent the growth of autumn shoots and increase the quality of dormancy.
Fourth, pruning
Pay attention to pruning, adjust the relationship between growth and results on the basis of plasticity, promote flower bud differentiation, achieve “internal and external resultsâ€, and promote fruit production and stable production. Saplings and Wangshu adopt measures such as light shearing, long deployment, and pull-twisting to ease the growth potential and promote flowering. For trees in the full fruit period, the degree of pruning is aggravated. Attention should be paid to the rotation of the result; the amount of flowers is greater. Weak trees, cut off some flower buds, reduce nutrient consumption, increase the accumulation of nutrients throughout the tree, and promote the growth of the entire tree. The wounds caused by trimming are closed in time with the "anti-corrosion film" to promote the growth of callus.
Fifth, clear garden sterilization
Pruning should be followed by pest control. Most of the pests are overwintering on the branches and branches of damaged fruit trees, on dry piles, and on branches and fruits scattered in orchards. This is the weakest link in their life history, and pests and diseases are easily controlled at this time. And eliminate.
Removal of fallen leaves, disease and fruit: For apple brown spots, gray spot disease, pear scab, grape brown spot, white rot, downy mildew, peach brown rot, and other pathogens, the winter The site is the fallen leaves, diseases, insects, and weeds in the orchard and should be burned.
Park spray disinfection: After the fruit trees fall, use the “General Tree Guardian†+ lime sulfur agent to clean the garden. General Tree Guardian is a compound preparation successfully developed by applying UV disinfection technology. The film-forming substance sprayed on the surface of the tree not only protects the tree, but also protects the body from frost, protects the flowers and preserves the fruit, enabling the flower buds to survive the winter safely.
Branches were painted white and scraped off the skin: The branches were painted white with the “General Tree Guardian†+ lime sulfur to prevent pests and diseases from damaging the trees. Some branches of the disease, first scrape the diseased skin, for the diseased tissue with a diameter of more than 1 cm with the "General tree maintenance" smear, can quickly form a protective film, asphyxiating sterilization, prevention and treatment of various skin lesions; The tissue with a diameter of less than 1 cm can be used to disinfect and sterilize the "crushed anti-corrosion film" so that the tree can be restored as soon as possible.
In short, the winter management of fruit trees cannot be relaxed. If the fruit trees are left to let them grow, it will cause the tree vigor to become weaker and weaker. The growth of fruit trees will be extremely sluggish, which will seriously affect the income of the fruit farmers. We must attach importance to the winter tube, create a good living environment for the dormancy of fruit trees, increase the fruit-setting rate in the coming year, and accumulate energy for the great harvest.
