The latest summer black grape planting management technology tutorial

Summer black grape is a grape variety, it is derived from Kyoho grape, but it ripens earlier than Kyoho grape, tastes better, and has no stone, high sugar content, popular. As its market demand increases, many growers see its benefits. At present, there is a certain planting area in our country. How should summer black grape be planted? Let's take a look.

1. Garden establishment

Summer black grape plantations should choose flat and open terrain, to ensure that there is a good drainage system, to choose rich organic matter, fertile loose, permeable soil. In the planting to eat deep ploughing of the soil, look at the 3-meter row spacing dug planting snow, in the ditch into the decomposed farm manure as base fertilizer, generally applied into 4000 kg per mu, with some appropriate amount of chemical fertilizer. After fertilization, cover soil and irrigate, let soil sink naturally, and fill ditch after water dries. Select high-quality seedlings for cultivation, planting depth and seedling depth in the nursery, too deep or too shallow are unfavorable for its growth.

2. Shaping and pruning

After planting, it is necessary to fight in time to introduce vines, and at the same time do a good job of summer shearing, including bud wiping, shoot fixing, topping, tendril removal and tendril binding. Bud wiping is generally carried out after the present order, generally leaving 2-3 buds per branch, eliminating abnormal buds and weak buds, and selecting strong buds with normal growth; shoot fixing is carried out before flowering, 1. New shoots qualified for moderate growth are reserved every 20 cm, and thin, over-dense and inappropriate new shoots are thinned in time; topping is carried out before flowering, and attention should be paid to the position of topping. Generally, large leaves are selected for topping; Timely removal of tendrils can save nutrients, conducive to fruit growth, when the new shoots grow to 50 cm when the timely tie tendrils, so as not to break. In addition, winter pruning should be carried out, generally after half a month of deciduous leaves, short shoots should be used to prune hair, fruit branches should generally stay 2-3 buds short, the rest should be thinned out, and dead branches, weak branches, over-dense branches, etc. should be pruned at the same time.

3. Flower and fruit management

Summer black grape grows vigorously, flower bud differentiation is good, most new shoots have more than 2 inflorescences, but in order to save nutrients and improve fruit quality, flowers need to be thinned, generally only 1-2 inflorescences are left on new shoots, and the rest should be thinned in time. At the same time, inflorescences that are too small, poorly developed and damaged by diseases and insect pests should be thinned. At the same time, in order to improve the fruit setting rate, timely fruit protection measures should be taken. Generally, gibberellin should be sprayed 4-10 days after flowering. After fruit setting, it should be fixed in time. When the fruit size is clear, fruit thinning should be carried out in time to remove small grains, large grains, abnormal grains, dense grains, pests and malformed fruit grains, so as to save nutrients and promote fruit growth.

4. Fertilizer and water management

Summer black grape is a variety that needs more fertilizer. In order to ensure high yield every year, we should pay attention to the use of organic fertilizer when fertilizing, so as to improve fruit quality and obtain higher economic benefits. Annual fertilization consists of base fertilizer, germination fertilizer, pre-flowering fertilizer, fruit swelling fertilizer, color conversion fertilizer and fruit picking fertilizer. Summer black grape in the whole growth period generally before germination and after freezing irrigation water can be, the rest of the time to pay attention to watering, especially in the flowering period, to control watering, so as not to reduce the quality of fruit.
