Two-year ripening of grapes
1 building park
Construction requirements: Light, temperature, moisture, soil and other conditions need to meet the grape's need for two-year growth.
1.1 Garden Selection
Convenient transportation, adequate light, convenient irrigation, and groundwater level below 1m.
1.2 Garden Planning
The contents of the plan include: rain-preservation and insulation facilities, operation areas, species selection and collocation, roads, soil improvement measures, drainage and irrigation systems, etc.
1.3 Variety selection
Choose early and mid-maturing varieties such as Xiahe, Victoria, Giant Rose, Goldfinger, and Kyoho.
1.4 rack selection
It is necessary to choose a shelf type with a large lighting area that is convenient for manual operations, such as a double cross V-shaped frame, which is conducive to manual operations such as topping, tying, fruit protection, and fruit thinning.
2 summer fruit management
2.1 Winter Shearing Garden
From the 12th to the middle of the second year, all the leaves fall off and the pruned garden is cleared in time, and the immature branches, thin and weak branches, disease and insect branches, over dense branches and residual fruits, residual branches and tendrils are cut off.
2.2 Broken sleep buds
Before and after the beginning of spring, the temperature of the buckle shed was raised, and the drug was promptly treated for germination;
After germination, the grapes can germinate about 10 days in advance and mature 7-10 days earlier.
2.3 Fruit Manipulation
Buds topping: After the winter buds germinate, the branches with too dense branches, leggy branches, and bad spikes are cut off to ensure that the winter fruit has enough mother trees;
Sparsely fruiting and thinning: 15 days before flowering, sparse spikes are planted, strong branches are left with 2 spikes, mean tree branches are left with 1 spike, weak branches are not eared, and at the 2nd time in the size of fruit peanuts, small fruit particles and deformities are removed. Fruit, inner fruit and dense fruit;
Chemical control tips: The overgrowth of vines is inhibited by foliar sprays of plant growth retardants such as mepiquat and chlormequat, and is coordinated with other cultivation measures and fertilizer and water regulation;
Pulling down the branches: During the middle and late stages, the branches are angulated and angled about the degree to promote winter bud differentiation and supply of fruit.
2.4 control of fertilizer
Before germination: prevent freezing damage in early spring and supplement zinc early;
Sprout to new growth stage: spraying boron fertilizer and chelating iron to promote robust growth of new shoots;
From flower bud stage to flowering stage: Spraying boron fertilizer and zinc fertilizer to promote robust development of buds;
After flowering to the ear formation stage: Spraying zinc fertilizer and calcium fertilizer can reduce physiological fruit drop and increase fruit setting rate;
Berry growth: spraying calcium fertilizer to prevent cracking and increase fruit firmness;
Fifteen days before fruit harvesting, the fruit coloring and tree nutrient accumulation were increased, and the fruit storage period after fruit harvest was prolonged.
2.5 bagging
After the fruit thinning is completed, the bagging is performed, and the fungicide is sprayed before the bagging.
2.6 Harvest
Harvest must be completed by July 15.
3 Tree restoration management
In the seven days after the summer fruit harvest, 45% compound fertilizer 30-50kg and organic fertilizer 1000kg were sprayed per mu.
4Fat water management
4.1 Moisture Management
Correctly control the watering time and watering time of germinating water, promoting shoot water, young fruit expanding water, berry coloring water, tree restoring water, cold-resistant wintering water;
When watering, it is necessary to flexibly determine the amount of watering and the period of watering in conjunction with the amount of fruit, rainfall, and soil moisture content;
Watering is prohibited during flowering, limiting watering 20-30 days before harvesting;
Watering is done by sprinkler irrigation.
4.2 Fertilizer Management
Accurately grasp five important fertilization periods such as germination fertilizer, fruit enlargement fertilizer, ripening fertilizer, tree restoration fertilizer and winter fertilizer;
Fertilizer fertilizer diversification: increase organic fertilizer; basal fertilizer, topdressing combination; root and root fertilizer supplement.
5 Pest control
Cut the garden in winter to reduce the source of bacteria; strengthen management, improve resistance; timely medication, disease prevention and treatment, and alternate use of agents.
