In production, many fruit growers tend to loosen the management of grapes after fruit harvesting, resulting in poor maturation of the branches in the year and suppression of rooting in autumn, which affects the yield and quality of grapes in the following year. Therefore, strengthening the post-management of grapes is of utmost importance to high-quality, high-yield and stable production in the coming year.
Protect autumn leaves. In the later stage of growth, the use of special thibetamum and sulfur pesticides should be strictly controlled to prevent premature leaf aging and reduce photosynthetic intensity.
Trim and clear the garden. On the basis of doing the summer cut work, continue to do a good heart beat, remove the tendrils and thin branches, and remove the severe diseased leaves. Clear the weeds in the garden, remove the diseased shoots, diseased leaves, diseased fruits, dead branches and debris from the garden and bring them to the park to be buried deep or burned to reduce the sources of diseases and insects.
Shi Xie after fertilizer. After the fruit is harvested, the quick-acting nitrogen fertilizer can be applied under the condition of multiple results and weak tree vigor. About 12 kilograms of available nitrogen fertilizer can be applied per acre, and 0.3% urea solution can also be sprayed on the leaves and sprayed 2-3 times.
Early base fertilizer. The time for applying basal fertilization is mid-to-late September, and it is most suitable for the deciduous vine before the latest in mid-October. Basal fertilizer is dominated by organic fertilizers and applied with phosphate fertilizers. Mushi organic fertilizer (farmers' manure) is 3000-5000 kg and phosphate fertilizer is 50 kg. Therefore, when the peak of root growth is reached, the roots are easily healed. Combined with fertility, the scotch can cut off the fine roots and play a role in root pruning. Many new roots can be promoted in the year, and the nutrients in the soil can be greatly absorbed in the early spring of the following year. .
Loose soil against drought. The orchards in summer and autumn are easy to be overgrown with weeds and timely cultivating and weeding after fruit harvesting. Deep plowing should be conducted between September and October, when severed roots can heal quickly. This time soil cultivation is often carried out in combination with the base fertilizer. Generally, the depth of cultivation is about 20 cm, and it is shallower near the trunk and deeper outward. In case of drought or winter drought, timely irrigation should be conducted to keep the field holding water no less than 60% in order to facilitate soil moisture.
