Meirenzhi Grape Cultivation Techniques
This article provides an overview of the knowledge related to Meirenzhi grape care for fruit trees, Meirenzhi grape cultivation techniques. Please refer to the detailed introduction below.
The Meirenzhi grape cultivation techniques mentioned in this article are the summary of fruit farmers' experience. I have been growing Meirenzhi grapes for 8 years. The orchard is located in the riverside areas of the south, which are hot and rainy in summer. Simple rain-shelter cultivation ensures good flowering and stable high yields every year. Let me share my own experiences in growing Meirenzhi grapes.
(1) Meirenzhi grapes have a vigorous growth. It is advisable to use grafting seedlings with less vigorous growth (such as Jufeng, Beida) to moderate the tree's growth and promote flowering.
(2) Use V-shaped horizontal frames, flying bird frames, flat shed frames, etc., to slow down the growth of new shoots. These frames provide good shading for the fruit clusters, promoting flowering and reducing sunscald.
(3) Pinch the tips of new shoots once when they have 7-8 leaves, and once after flowering. When the entire frame is covered, control the growth strongly. Leave 4-5 sub-shoots with 2 leaves above the inflorescence and pinch the tips to prevent sunscald on the berries.
(4) Strictly control nitrogen, apply organic base fertilizer at 50-60% of the amount used for conventional varieties, and appropriately increase the application of phosphorus and potassium fertilizers.
(5) It is not recommended to use gibberellic acid to promote flowering, as it often results in many small and僵 fruit. Natural fruit setting is high, and pinching after flowering combined with watering during the flowering period can reduce the labor required for thinning.
(6) Leave about 3000 shoots per mu, with the proportion of fruiting branches being 60-70% of the total branches. Leave about 2000 fruit clusters per mu, with each cluster weighing between 800-1000g. Avoid clusters that are too large, as they may not color well.
(7) It is best to lay reflective film on the ground to promote coloring. After the hardening period, use more phosphorus and calcium fertilizers in foliar applications.
(8) 60-65 days after flowering, perform a girdle on the trunk to promote coloring, increase sugar content, and accelerate maturity.
(9) Remove the bottom 3 old leaves of the new shoots 20 days before harvest, remove the bags 15 days before harvest, and remove the top 3-4 sub-shoots of the fruit clusters to ensure adequate light penetration and coloring.
(10) Winter pruning should focus on medium-length shoots with 5-7 buds, supplemented by short shoots with 2 buds, leaving 7000-8000 buds per mu.
