Many people like to eat grapes. The grape taste is sweet and delicious, and the nutritional value is high. Today we introduce you to the summer black grape planting technology.
Introduction of Xiahe Grape:
Summer black grapes are produced in Japan, the descendants of Jufeng. Early-maturing European and American varieties, you can eat grapes in July. Summer black grapes are characterized by early maturity, no nuclear, high sugar and low acidity, rich flavor, crisp meat and medium hardness, which are relatively hard in European and American grapes.
Fruit taste: sweet and delicious, slightly sour, skin tightly stained with flesh, can not spit skin. It is one of the most delicious grape varieties on the Chinese market.
Planting technology is strong in summer and black, and the flower buds are well differentiated. The solid branches can also produce flower spikes. The leaves stand upright, the leaves are dark green, the photosynthetic efficiency is high, the cultivation and management are easy, and the cultivation effect is better. Can be used for cutting or grafting.
Young tree management rack type: "high, wide, vertical T-frame", in addition, summer black is also suitable for scaffolding cultivation.
Digging and fertilizing: Digging and fertilizing before planting, planting at a planting distance of 1m, planting the root water and covering the mulch.
Wiping buds: After germination, double buds, multi-head buds, and weak buds are removed; after forming new shoots, the wires are bound to the two sides, and the tips are fixed at a distance of 15-20 cm.
Sparse and fixed production: after the bud to the early stage of flowering, the extra large spikes and weak spikelets are removed.
Thinning and thinning: The fruit setting rate of summer black is very high. It should be removed one week before the flower and several spurs under the auxiliary ear, and the tip of the stalk is not even pointed at the tip of the ear to keep the conical ear. After the flower falls and the fruit is stable, the fruit is scattered.
Ring stripping: In the first immersion agent, the stripping is carried out on the trunk branch, the width is 2~3mm, and it is deep to the xylem. Then the tape is tied with the tape to promote the increase of the fruit. When the berries are just beginning to color, they are stripped and can mature early.
After the application of the swelling fertilizer: in general, after the Xiehua, timely application of fully decomposed chicken manure or cake fertilizer, 200kg per acre, combined with ternary compound fertilizer 30kg, potassium sulfate 10kg, divided into two applications.
Apply coloring fertilizer: When the berry turns color, apply 10~15kg of potassium sulfate per acre. In combination with spraying pesticides, add foliar fertilizer 0.3% potassium dihydrogen phosphate or 0.6% Baolifeng 2 .
Controlling the new shoots: After the fruit is bagged, especially during the coloring period, the growth of the new shoots should be strictly controlled, which is the key to the management of Xiahe. Failure to do so will result in slow coloring and delayed maturity. The growth of new shoots can be inhibited by topping or foliar application of chlormequat, but the most important thing is to control the amount of nitrogen fertilizer and increase the proportion of phosphorus and potassium fertilizer. After several years of planting, it can be thinned, expand the canopy, and maintain a balanced growth.
Autumn Shiji Fertilizer: After harvesting the fruit, at the end of August and the beginning of September, it can be combined with deep-turning per mu to apply 4000~5000kg of decomposed organic fertilizer (such as pig manure), 50kg of superphosphate, and make a high ridge.
Well, the above is the Xia Hei grape and planting technique that Xiaobian introduced for you briefly. I don't know if you have already know a little about the cultivation method of Xiahei grape.
