What is the reason why the grapes don't bear fruit?

Grapes are our common fruit, and they are very popular with people. Some people tend to plant a few trees in their own yard, but many people report that their vines have not borne fruit. What is the cause at this time? I don't know what to do The editor has summed up some experience for you. Let's have a look.

First, the cause of non-result

1. Variety reasons

When some friends buy seedlings, they may be cheated by businessmen to buy seedlings of very poor quality, and then diligently manage them after planting, and this kind of seedlings will not bear fruit.

2. Time is not up

Grapes, especially their own fruiting time, when some seedlings are bought back, the seedling age is relatively short, only 1-2 years old, so no matter how good the planting management is, it will not bear fruit so quickly, and it will bear fruit naturally in its fruiting time.

3. Insufficient fertilizer

Growing grapes is the key to fertilizer. Applying enough basic fertilizer should be applied continuously in summer and autumn to accumulate nutrients in the second year, so that more branches and leaves can sprout in the next spring.

4. The growth environment is unfavorable.

When growing grapes at home, light and ventilation are more important. if you grow in an environment with insufficient light and poor ventilation, it will bear less fruit year by year until it does not bear fruit.

5. Pruning

It should be pruned before flower bud differentiation in spring, topdressing once when sprouting, and organic fertilizer should be selected to provide sufficient nutrients for plants to germinate more buds and lay the foundation for high yield.

II. Solutions

1. Growth period management

After flower bud differentiation, if there are too many buds, an appropriate amount of buds can be wiped out as soon as possible, which can reduce the nutrient consumption of plants. When the new shoots grow to 15-30. In centimeters, tie up less in time, and remove the tendrils at the same time; at the same time, remove all the secondary shoots below the ear, leaving 2 leaves above the ear. After flowering, it is necessary to make a good inflorescence and the sleeves of fruit trees, leaving a well-growing inflorescence on one fruiting branch and thinning the rest.

2. Fertilizer and water management

Fertilization is essential for high yield of grapes. according to studies, for every 100 kg of grapes, 0.75 kg of pure nitrogen, 0.75 kg of phosphorus and 0.63 kg of potassium are needed. Therefore, when base fertilizer is applied from fruit harvest to shoot ripening, quick-acting fertilizer is generally applied in 10-15 days at flowering stage, and base fertilizer is suitable for fruit development in July, there are obvious weeds. Spraying low concentration borax solution and calcium superphosphate solution during flowering and fruiting stage can increase fruit setting rate and yield. It is necessary to keep the soil moist before flowering and improve the favorable conditions for flowering and fruit setting, but the flowering period should not be watered. The fruit needs a lot of water after fruit setting. At this time, it should be watered every 7-10 days according to climate change, but it should not be watered during the fruit coloring period so as not to reduce sweetness.

The above is the introduction of the reason why the grape is not the result. I hope it can help you. If you want to know more about it, please follow us.
