First, control the amount of results
a. Grapes are easily fruit varieties. If the result is not controlled during planting, the tree vigor will be weakened, which will affect the output in the coming year. Too much fruition is not conducive to fruit enlargement. The fruit after ripening is small. Poor quality.
b. During the fruitful period of the grape, the amount of real estate fruit per mu is controlled at about 3000kg.
Second, enough fat enough water to ensure nutrient supply
The fruit growth period should ensure adequate supply of fertilizer and water. The specific operations are as follows:
1. Pour germinate water before germination to make buds consistent and neat.
2. Control water and nitrogen after germination to flowering, so that the growth potential of new shoots will remain moderate, so as to benefit the results.
3. After the fruit is set, the fertilizer and water supply will be strengthened to prompt the rapid expansion of fruit and increase the yield.
4. Apply sufficient amount of fertilizer and water in time after fruit harvesting and supplement the nutrient consumed by the tree in order to restore the tree vigor.
5. Apply base fertilizer before falling leaves:
a. Base fertilizer is mainly farmyard manure, applying 3000-5000kg of organic fertilizer, 60-70kg of urea, 100-150kg of superphosphate and 2000-3000kg of plant ash per mu.
b. 95% of the total amount of fertilizer is applied as basal fertilizer, 80% of urea is applied when basal fertilizer is applied, and 20% of urea is applied during fruit enlargement period.
Third, strictly control the results of the site
a. Outward movement of the resulting parts will reduce grape production.
b. The old branches after the results are cut off in time to cultivate new mother trees.
c. Strengthen the update and pruning. Annually adopt single-branch update, double-branch update or multi-branch update and other measures to strictly control the outward movement of the resulting parts.
Fourth, control the amount of branches
a. Grapes have multiple branching habits such as secondary branching and tertiary branching. They will consume a lot of nutrients and affect the light, so they need to control the amount of branches.
b. Auxiliary shoots: All of the following ears are removed, and there are space reservations above the ears to ensure good ventilation of the fruit trees.
V. Enhancing Ear Management
a, before the flowering, according to the growth of the branches of the inflorescence, strong new shoots to stay double ear, left 1 spike in the mean tree branches, weak branches do not leave the ear.
b. For the preserved inflorescences, the spikelets and the long spikelets must be cut off, which is beneficial to the growth and development of the ear and enlargement of the fruit.
Sixth, strengthen pest control
Grape pests and diseases will affect the photosynthesis of grapes and hinder the accumulation of photosynthetic products. Therefore, the prevention and control of pests and diseases must be strengthened during the planting process.
