Late grape management points

Ensure that the grapes are safe for winter and lay a good foundation for grape production next year. At the same time reduce the number of pathogenic bases in the field and ensure a bumper harvest in the coming year. Grape irrigation, fertilization, winter cutting, clearing the park, and burying soil should be done in a timely manner. In particular, wintering and cold-proof work should summarize the experience and lessons of over-wintering over the years, filling the overwintering water, and burying the soil according to technical regulations. Arrangements, early actions, and implementation. The specific work is now arranged as follows:

Irrigation: Promote the restoration of tree vigor and promote root growth;

Second, fertilization: autumn basal fertilization should be applied before October 15, fertilizer with grape organic fertilizer 200 kg / acre and farm fertilizer, (farm fertilizer to three kilograms of fertilizer a kilogram of fruit ratio, not less than 3 per acre Fang), adding three-element compound fertilizer 10 kg/mu and oil residue 150 kg/mu at the same time.

Third, pruning: (a) fresh grapes from mid-October to October 25 ends. All branches below 90cm are required to be cut off to ensure the ventilation of the ventilation belt to reduce the occurrence of diseases; a result branch is left for every 30cm above 90cm, a mother branch is left for 4-5 years for the three-year tree, and 2-3 are for the fence. , 1-2 scaffolds, arranged in a fishbone, focusing on the extension of the election of branches. Early and mid-maturing varieties (non-nuclear purple, purple no-nuclear, white chicken heart, Frey, red) leave 1-2 buds per mother tree, and the late-maturing variety Krisen leaves 2-3 per mother tree Buds, strictly controlled in the 8-10 ear, the yield per mu is controlled at about 1 ton, can not be overloaded, increase the commodity rate. (Be sure to learn too many lessons from ripening and late fruiting in 2014.) Six-year-old grapes are thinned by the method of “every three to one” and sawn from the surface to solve the problems of canopy closure and poor coloring of grapes. (2) Wine Grapes 1. Pruning in the new garden, selecting and maintaining the newly cultivated year as the main vine, and determining the length of the main vines to be cut based on the maturity. For each plant, 1-2 mature vines with good maturity were selected and the height of cut was controlled within 1 meter to prevent the resulting parts from moving outwards. All the 40-50 cm bases were removed, leaving no result mother twigs. 2. The 2-3 year old tree pruning is trimmed using the dragon dry shaping method, leaving 1-2 main vines per plant and 2.5 main vines per meter. The main vine trim height can be controlled at about 1.3 meters depending on the height of the frame. For each main vine, leave 5-7 results between the heights of 60-130 cm, and leave a mother branch at 15-20 cm intervals. The main vines are distributed evenly, and the mother branches are 2-3 buds. The extension branches cut 5-6 buds. 3. The age of four years or more is mainly to solve the problem of confined trees. The number of masters should be controlled. The main ranch of the fence should be controlled within 3/meters, using the tips of 1-3 buds.

Fourth, off the shelf and spray medicine: the grapevines will be fine pruned, along the direction of the line to a direction of the shelf, put the vines flat on the ground, straight, tied, lined up in a line, the vines and the ground spraying 3-5 Baume's lime sulfur or equivalent Bordeaux fluid reduces the number of pathogens.

V. Qingyuan: This year's grape disease is serious. Special attention must be paid to the work of the Qingyuan Garden. After the grape is pruned, the garden shall be cleared promptly, and all the sick ears, diseased fruits, diseased branches, diseased leaves, and weeds in the garden shall be removed and transported to the outside of the park for burning or deep-buried so as to reduce the number of pathogenic bacteria. Sixth, buried soil time: from late October until the end of November 2, small trees should be early.
