How long is the grape fruiting period
A small knowledge of life, introducing the duration of the grape fruiting period in the green plant flower aspect, if there are any mistakes, please correct!
How long is the grape fruiting period
The grape fruiting period is about two months, there are many varieties, and the maturation time is also inconsistent. When planting grapes, it is necessary to apply fast-acting fertilizers before and after flowering, pay attention to the management of new shoots, improve ventilation and lighting conditions, timely pinch the tips, tie the vines, control the growth of lateral shoots, to ensure the yield and quality of the later stage of grape fruiting.
How long is the grape fruiting period
The grape fruiting period is about two months, as the variety and planting methods differ, the fruiting period also varies. How long does it take for grapes to bear fruit? Generally, after planting seedlings for 2-3 years, they can grow, and after 6-7 months, they can bear fruit. When is the grape expansion period? The grape expansion period is between June and July every year, usually three weeks after July. Basically, in June to July, the expansion period varies with different geographical locations.Grape ripening time
Grape varieties are diverse, and the ripening time is also inconsistent. The earliest ones are available in late May and early June, and those grown outdoors last from July to the end of October. In greenhouse cultivation, they can ripen two months earlier, and in greenhouses, they can ripen one month earlier.Grape fruiting period care and management
The grape flowering period coincides with the differentiation period of the second-year flower buds and the rapid growth period of new shoots. Flowering, flower bud differentiation, and new shoot growth all require a large amount of nutrients, so this period is a key management period for grapes. In the flowering period, the following management tasks should be emphasized: 1. Apply fast-acting fertilizers before and after flowering; 2. Pay attention to the management of new shoots, improve ventilation and lighting conditions; 3. For female sterile varieties and varieties with poor pollination, artificial pollination should be carried out; 4. For varieties with severe flower and fruit drop, pinch the tips when flowers are seen and spray boron fertilizer.How to fertilize grapes during the fruiting period When the grape berries are the size of soybeans, both the vegetative growth and fruit growth are rapid, and a large amount of nutrients are consumed. It is necessary to apply a fast-acting fertilizer in time to promote berry expansion. Generally, diammonium phosphate is chosen, and 5kg of flat-line冲施肥 with a content of 15-10-30 can be applied per mu. When the berries start to color, apply a top dressing with potassium fertilizer as the main ingredient, which can increase the sugar content of the fruit, promote coloring, and mature the branches. Apply about 15 kg of potassium sulfate and 15 kg of calcium superphosphate per mu. From fruit setting to maturity, spray 3-4 times of 0.2%-0.4% potassium dihydrogen phosphate, which can increase yield and improve quality. Spraying a 0.05%-0.1% magnesium sulfate solution during the fruit setting period and fruit growth period can increase berry yield and sugar content. For grapes deficient in iron and chlorotic, repeated application of ferrous sulfate has a good effect. Spraying should be done in the clear morning at 8-9 am or in the afternoon at 3-5 pm. What to spray on grapes during the fruiting period Grapes can be treated with chlorpyridine, gibberellin, pyridine, thiazine, etc. After physiological fruit drop 15-20 days after flowering, when the fruit is about the size of soybeans, dip the fruit cluster in 30ml/bottle of thiazine for 2-3 seconds, which can increase the fruit size, avoid fruit stalk hardening, improve marketability, and enhance storability.The above is the detailed content of how long the grape fruiting period is, hoping it can be helpful to you!
