What methods are used for grape seedling cultivation
Grape summer seedling cultivation is a new technology that has developed in recent years. This technology enables fruit farmers who cannot plant in spring due to financial, seedling, and land reasons to achieve their dream of establishing an orchard in the same year, with simple methods, high survival rates, and easy management.
Seedling Selection
① Seedlings in a plastic greenhouse in spring; ② Hardwood cuttings stored from the previous year; ③ Current year's young seedlings planted in the field.
Variety Selection
Choose the currently better varieties. Among fresh food varieties, early-maturing varieties include Hongshuangwei, Heizhiyu, Guifei Rose, Zizhenxiang, and Jinxiu; mid-season varieties can choose Jingyou, Dali Meigui Xiang, etc.; Thomson, Beauty, and弗雷 can be used for seedless variety breeding; wine-making varieties include Shelongzhu, Chixiazhuzhu, Xila, and Baiyu Nihong.
Land Preparation
In the selected garden, it is best to dig a ditch 60 cm wide and 60 cm deep from north to south, and place an appropriate amount of wheat, corn, and other straws at the bottom; then apply 5000 kg of mixed manure per mu and mix it with a certain amount of soil; fill the rest of the land, make a ridge, and water it; when the soil is loose, it can be planted.
Planting Time
Planting can be done from late May to early July. It is best to choose cloudy days, after the rain, and in the afternoon.
Planting Method
Taking the nutrient pot seedlings as an example, first cut the plastic bag top and bottom with a blade, then plant it into the prepared planting row. The appropriate depth is 3 cm above the ground for the new shoots; immediately press the surface tightly and water after planting. When the soil is loose, use a plowshare hoe to maintain soil moisture.
Management after Planting
① Under water and fertilizer management, when the young seedlings' new shoots grow to 7-8 leaves, apply 30-50g of urea per plant; 20 days later, apply 50g of diammonium phosphate; after another 20 days, apply compound fertilizer of potassium sulfate 100～200g; water immediately after fertilization. ② After pruning and shaping, when the new shoots grow to 7-8 leaves or more, pinch the tips to force the production of secondary buds, leaving 3-4 secondary buds.
Disease and Pest Control
When the new shoots grow to 5-6 leaves, spray 80% spray liquid 600-800 times per gram, and add an appropriate amount of insecticide; after half a month, spray 50% carbendazim 500-600 times; in autumn, when the temperature is low and humidity is high, pay attention to the control of downy mildew, spray 78% cobalt 600-800 times solution once.
The above is a specific introduction to the methods of grape seedling cultivation, hoping to bring some flower knowledge to flower enthusiasts.
