The greenhouse vine cultivation solves the problems of many diseases, low fruit setting rate, monotonousness and inferior quality of the open viticulture. Early or delayed ripening of grapes makes it difficult to grow European and Asian varieties. The cultivation of European and Asian grape varieties has been successful. Through cultivation of greenhouses, it is also possible to ensure that the grapes are fully ripe and harvested and the characters are improved.
First, build a park
1. The structure of the greenhouse adopts a single building or arched steel pipe or bamboo shed, the shed is 6-8 meters wide, the shoulder width is 1.6-2 meters, the ceiling height is 2.8-3.2 meters, the length is not limited, the north-south direction, the film is covered with polyvinyl chloride Longevity film or ethylene vinyl acetate film.
2. Racks two rows per shelf, spaced 3-4 meters apart, adopting a “Y†or “double cross†hedgerow or planting 1-2 rows of arched small scaffolds 1.8-2 meters high .
Second, planting
1, ready to open straight through the ditch before planting, deep 60-80 cm, 80 cm wide, unlimited length. The cement pillars are laid every 4 to 4.5 meters apart, and 5,000 kg per mu of decomposed organic fertilizer is mixed with 2% superphosphate or calcium magnesium phosphate fertilizer as the base fertilizer, and mixed thoroughly with the soil and poured into the ditch to prepare for planting.
2. Planting seedlings will be planted in December in winter or 2-3 months in spring. Electric nursery seedlings were sowed in late January-early January and planted in the middle and late April. In the greenhouse, two lines were planted with a spacing of 3-4 meters; plant spacing: 1.5-2 meters for strong tree vigor and 1 meter for vulnerable varieties. The seedlings in that year performed cultivation for sheltering from rain.
Third, seedling management
1, thin fertilization after planting water after planting, in the seedling germination or slow seedling stage lag, thinning fertilizer every half month or so (to avoid too thick fertilizer), to mid-August, stagnating nitrogen fertilizer application of phosphorus and potassium fertilizer Times, spray spraying, increase the application of fertilizers.
2. Disease prevention and pest control Generally, the Eurasian grape varieties are more sensitive to Bordeaux fluid with a large amount or lime, and they are changed to fungicides during young leaves, such as carbendazim carbendazim or methatrine or Dupont Fuxing, etc. After aging, it can be used Bordeaux mixture or Dasheng M-45 to prevent downy mildew, etc., and downy mildew has been used to prevent and control the use of phos-phos-methyl forskolin. Strictly prevent the beetle feeding leaves and avoid spraying herbicides.
3. Tree-shaped fence: When the seedlings are 70-80 centimeters high, they will be picked up and dried, and the top two will be selected for the tip. A wire will be pulled at 70-80 centimeters so that the two shoots will be split on both sides. When the main vine grows 82-100 centimeters, it is tossed again to increase the thickening, and then the second draw is used to draw the leaves, leaving 4-6 leaves to pick up the heart; the small scaffolding: the seedlings are uniaxially extended to 1 m after the shed and then picked up. In this way, until the autumn tree has basically had the result conditions.
Fourth, cultivation points
1, to promote the cultivation of grape winter dormancy required low temperature hours below 7.2 °C about 1500-2000 hours, a full low temperature dormancy can improve the germination and flowering of the whole
