How big do grapes have to be to swell?

Summer black grapes have the advantages of early ripening, good taste and strong resistance to stress, which not only consumers like to eat, but also are favored by growers. So, how should summer black grapes be grown? What kind of fertilizer can be used for summer black grapes to enlarge the fruit?

What should I pay attention to when growing summer black grapes? Let's take a look!

1. Summer black grape sowing management: about half a month after the leaves fall in winter, winter pruning work is carried out. The main focus is on the current year's fruit branches, keeping the three buds for stubbing, and removing the excess branches.

When pruning, it is common to prune inwards to prune off some of the weaker branches and dense branches to improve the air permeability of the summer black grapes. Foliar fertilization of Kintara increases the soluble solids of the fruit, increases the sugar content of the fruit, promotes early coloration, and uniform color depth. At the same time, it can increase the firmness of the fruit and prolong the storage period.

Summer black grape ears should be neat, and if the ears are too long, pinch the tips of the ears in front of the flowers. On average, there is only 1 ear left on each result branch. At the top of the shelf, two ears can be left on the luxuriant branches.

Medium-growing sprouts have 1 ear on them, and the branches are weak, and the cultivated branches have no ears. In summer, the black fruit is relatively dense and has strong growth ability, and timely fruit thinning can increase the yield. Bagging of summer black grapes during fruit setting can prevent diseases, pests and diseases, bird damage, yield and quality.

The fruit produced is not only beautiful, but also tastes great. Therefore, regardless of the cultivation method, bagging measures should be taken to improve yield and quality.

2. Fertilizer demand law and fertilization technology of summer black grapes: summer black grapes have a relatively large demand for potassium fertilizer in the whole growing season. Nitrogen fertilizer should be applied appropriately during the growth period, flowering and fruiting stage and flower bud differentiation period.

Avoiding nitrogen deficiency can lead to stunted growth, stunted fruit development, poor flower bud differentiation quality, and severely affect yields. Applying phosphate fertilizer at the right time in the early stages of growth can promote shoot maturation and flower bud differentiation, improve pollination and reduce fruit drop. In order to ensure the fruit quality and yield of summer black grapes, the basal fertilizer should be re-applied, mainly the decomposition of the round key machine fertilizer, the summer black grapes have higher requirements for photosynthesis, should be timely and appropriate amount of surface root topdressing, and spray Jintai two poisons 2000 3000 kg of water bright cavity can promote fruit swelling, supplement a variety of trace elements required for fruit growth, and prevent fruit breakage.

In short, summer black grapes are in greater demand in the market and are more profitable to grow. As long as growers master the cultivation methods to ensure a high yield of high-quality summer black grapes, they can increase their income.

Grape swelling can use grape water-soluble fertilizer, molar water-soluble fertilizer five kilograms to apply to an acre, water consumption of about 1000kg, fully dissolved can be applied to the roots of grape plants. If the temperature is high, the concentration should be reduced, try to choose a windless and cloudy day or cloudy day for spraying, and on a sunny day, the belt cavity should be carried out after the morning dew is dry to before 10 o'clock or after 4 p.m.

Grape swelling with grape water-soluble fertilizer, five kilograms of water-soluble fertilizer for Moshout Saner to rush one acre, the water consumption is about 1000kg, and the grape plant roots can be washed when the dissolution is sufficient. There are two points to pay attention to in the time of water-soluble fertilizer application, one is to apply it once every ten days, which can make each nutrient can be fully absorbed, and another point is that after the grapes flower, they need to be topdressed in time to promote the grapes to fully supplement nutrients.

When the grapes are in the swelling stage, you should use some balanced water-soluble fertilizer so that the grapes will grow particularly well.
