Cultivation Techniques of Zui Jin Xiang Grape

Zuijinxiang grape can spray Zhuangsu to control the shoot before flowering, in order to increase the fruit setting rate, appropriate fruits and vegetables should be applied after fruit setting, and expanding agent can be sprayed when the fruit grows to the size of soybean. Heart-picking: cut off all the leaves at about 8 leaves 10 days before flowering, gently pick the heart when flowering and fruit 12 leaves, and remove all the accessory shoots above the inflorescence. Water and fertilizer: the whole growth process needs to be fertilized for about 5 times, including base fertilizer, budding fertilizer, fruit expansion fertilizer, color conversion fertilizer and fruit picking fertilizer, and should be watered in time after each fertilization.

1. Key cultivation techniques

The main results are as follows: 1. Zuijinxiang grape can be sprayed properly before flowering to control the shoot, which is beneficial to improve the fruit setting rate.

Generally from 2 days before flowering to flowering, the foliar spray of 500-675 milliliters per liter is about 15 milliliters of 25% zhuangsu, mixed with 5-7.5 kilograms of water, so that the growth will stop a little bit during the flowering and fruit setting period, thus increasing the fruit setting rate and increasing the ear weight by about 100 to 200 grams.

2. The expanding agent can be used properly for fruit.

After the fruit is set, the fruit can be thinned properly, and when the fruit is as big as soybean, the special expanding agent for grape can be used and sprayed on the ear with water, which is helpful to improve the fruit hardness and increase the grain weight by about 1 gram.

2. Targeted cultivation techniques

1. Pick the heart

SO4 rootstock and Beida rootstock can generally be cut twice, usually at 8 leaves about 10 days before flowering, light coring can be carried out in batches when flowering and fruiting 12 leaves, and red Fuji rootstocks and cuttings are properly coring at about 11-12 leaves before flowering.

2. Deal with the secondary tip

All the secondary shoots above the inflorescence are erased or leave a leaf to remove the heart.

3. Top accessory tip

After the 11-12 leaves of the plant are coring, the top accessory shoot can leave 3-5 leaves for coring, and then carry on the strong control.

4. Setting ears, fruits and vegetables

The 10 vine has 8 ears, about 2000 spikes, and the yield is about 1250-1500 kg. After fruit setting, fruit thinning should be carried out properly, and fruit should be properly retained per panicle to remove relatively small grains and seedless fruits.

5. Reasonable water and fertilizer

(1) Fertilizer amount: water and fertilizer should be carried out in time in the process of plant growth, and the amount of fertilizer can be adjusted according to tree age, rootstock, fruit quantity, soil quality and plant growth, usually about 1 ton of chicken manure, 10-15 kg of urea, 50 kg of potassium fertilizer, 50 kg of phosphate fertilizer and 50-60 kg of nitrogen, phosphorus and potassium compound fertilizer.

(2) fertilization times: generally, plants need to be fertilized for 5 times in the whole growth process, such as base fertilizer, budding fertilizer, fruit expansion fertilizer, color conversion fertilizer and fruit picking fertilizer.

(3) timely watering: after each fertilization, must be watered in time, in case of drought during the fruit expansion period, timely water supply should not be excessive watering, otherwise it is easy to cause leaves to turn yellow and fall leaves.
