Detailed Explanation of Key Cultivation Techniques for Pineapple Grape

To cultivate pineapple grape, one needs to master aspects such as planting time, male-to-female plant ratio, fertilizer and water management, and pruning methods. In southern regions, planting can be done from December to March of the following year, while in northern regions it can be done in March-April. Male and female plants are paired at a ratio of 9:1, and topdressing follows the principle of light and frequent applications. Prune evenly according to growth status to control vigor.

Field Management of Pineapple Grape

1. Erecting Supports

Pineapple grape is a vine plant with growth management similar to that of grapes. After planting, supports must be erected. In the year of planting, simple posts can be set up, or short-cane cultivation can be used to control the growth of lateral shoots.

2. Pruning Shoots and Buds

In the first year of planting, keep three buds per plant. If the main trunk produces one bud, wait until the new shoot grows to 2-5 leaves and then pinch off the growing tip. After pinching, lateral shoots will sprout; keep three strong buds and remove all other buds.

3. Pinching

Commonly known as “three dragons”: leave three main vines, keep 1-2 leaves on other lateral shoots, and repeatedly pinch the growing tips. Repeat this process of retaining shoots and pinching until after autumn. The purpose is to control the upper part and promote the lower part, so that the upper main buds do not sprout under stimulation, and the lower main buds develop plump and fuller, using the lower buds as fruiting mother branches for the next year.

4. Pests and Diseases

Pineapple grape comes from mountain forests, so pests and diseases are few. Generally, for disease control, sprays such as carbendazim, thiophanate, tricyclazole, and chlorothalonil can be applied.
