The latest greenhouse grape harvest management

Grape is a perennial fruit tree, the results will consume a lot of nutrients, so generally after picking fruit will be timely tree restoration management. We also need to clean up the garden and prevent pests and diseases. However, the grapes planted in greenhouses have fewer diseases, fewer litter and limited fertilization, so let's see how to manage them.

1, pruning

After picking fruit, it is mainly pruning task, slowly withdrawing pigs from the ground by 50 cm, promoting latent bud germination, cultivating new main vines to do the fruiting mother branch of the next year, in fact, renewing the fruiting mother branch and restoring new vitality. Complete in time after fruit picking. Long slightly pruned, the main vine after the fruit retracted to the corner of the trellis, promote germination and culture of fruit mother branches.

2. Management of new shoots

After pruning and retraction, a large number of new shoots have been promoted, and it is time to start managing the new shoots. Leave strong, appropriate node position of new shoots, others are removed, redundant shoots are also consumed nutrition, the main vine, evenly leave shoots, cultivate into fruit mother branches, grow to a sufficient length when the core, so that the main growth of new shoots. The young shoots grow to nearly two meters before they are picked.

3. Restore tree vigor

After the regeneration is completed, fertilizer is needed, preferably one tree by one, 50 grams of urea and 150 grams of compound fertilizer are applied to each tree. Because fertilizer is not much, need to plant fertilizer, absorption is good. However, when applying base fertilizer in autumn, it is necessary to use ten thousand catties of farm manure per mu. Can furrow fertilizer, because the amount of fertilizer is too much, furrow fertilizer can be evenly applied.

4. Cleaning and prevention

The front pruning is to renew and rejuvenate, but there is no comprehensive cleaning. We need to clean up some dead branches, over-dense branches, and some sick and withered leaves and branches. Full sterilization should be initiated. All carbendazim sprayed, ground and roots not to be missed. It can be sprayed when the soil is turned over and fertilized. Choose methyl thiophanate, mancozeb, chlorothalonil and other agents can also be.

Greenhouse planting grape harvest after management has some different, base fertilizer use time interval is longer, only a small amount of topdressing. It is updated mainly by pruning.
