Grape post management points

Make sure the grapes are safe for winter and lay a good foundation for grape production next year. At the same time, reduce the number of pathogens in the field to ensure a bumper harvest in the coming year. Grape irrigation, fertilization, winter shearing, clearing and burying should be done in time, especially for wintering and cold-proof work. The experience and lessons of wintering over the years should be summarized, and the wintering water should be filled and filled, and the soil should be buried according to technical regulations. Arrange, act early, and do a good job. The specific work is now arranged as follows:

1. Irrigation: promote the restoration of tree potential and promote root growth;

Second, fertilization: Qiu Shi base fertilizer should be applied before October 15th, the fertilizer is mainly based on grape organic fertilizer 200 kg / mu and farmyard manure (the ratio of farmyard manure to three kilograms of fertilizer and one kilogram of fruit, not less than 3 per mu) Party), adding 10 kg/mu of three-element compound fertilizer and 150 kg/mu of oil residue.

Third, pruning: (1) table grapes will end from mid-October to October 25. All the branches below 90cm of the main vines are required to be cut off to ensure the smoothness of the ventilation belt and reduce the occurrence of diseases; a result branch is left every 30cm above 90cm, 4-5 results are left in the three-year tree, and 2-3 parts of the fence There are 1-2 scaffolding parts arranged in a fishbone shape, focusing on the extension of the branch. Early-maturing varieties (nuclear purple, purple incense, non-nuclear, white chicken heart, Frey, red extract) leave 1-2 buds for each result, and 2-3 buds for each late-maturing variety Cresson Bud, strictly controlled in 8-10 ears, the yield per mu is controlled at about 1 ton, can not be overloaded, and increase the commodity rate. (Be sure to learn from the lessons of too many mature nights in 2014.) The six-year-old grape adopts the method of “three to one” to cut thinning from the ground surface to solve the problem of poor closure and poor grape coloration. (2) Wine Grapes 1. The new garden is pruned, and the new one is selected as the main vine. The length of the main vine is determined according to the maturity. Each plant is selected to retain 1-2 mature vines with a good maturity. The height of the cut is controlled within 1 meter to prevent the result from moving outward. The base is removed 40-50 cm, leaving no result. 2. 2-3 years of tree age pruning is trimmed by dragon dry shape, leaving 1-2 main vines per plant, leaving 2.5 main vines per meter. The main vine trim height can be controlled to about 1.3 meters according to the height of the frame. Each main vine leaves 5-7 fruit branches between 60-130 cm high, and each branch is separated by 15-20 cm. The main vines are evenly distributed. The mother branches are cut 2-3 buds, the uppermost part. The extended branch cuts 5-6 buds. 3. Four years old and above, mainly to solve the problem of tree closure. The number of main vines should be controlled. The main vine of the hedgerow should be controlled within 3/m, and trimmed with short tips of 1-3 buds.

Fourth, the shelf and spray: the trimmed grape vines, along the line and down in a direction, put the vines on the ground, straight, bundled, lined up, sprayed on the branches and the ground 3-5 Baume's stone sulphur mixture or equivalent Bordeaux mixture reduces the source base.

5. Qingyuan: This year's grape disease is serious, and we must pay special attention to the work of Qingyuan. After the grapes are pruned, the garden should be cleared in time to remove all the diseased ears, diseased fruits, diseased branches, diseased leaves and weeds in the garden, and transport them to the garden for incineration or deep burial to reduce the number of pathogens. Sixth, buried soil time: from the end of October to the end of November 2, the small tree should be early.
