Uneven grape size and slow fruit swelling? These management measures need to be in place

The period of grape young fruit enlargement is a very important stage in grape growth. Whether the management at this stage is in place directly affects the grape yield and quality of the year. So where is the focus of management?

1. Branch and vine management

After the new shoots grow, one week before flowering, leave four leaves in front of the inflorescence at the forefront of the fruiting branch to pick the heart.

The secondary shoot that grows from the new shoot, only one secondary shoot at the top of the new shoot is left, and the rest is wiped out. When the secondary shoot grows to 5 leaves, the heart is removed, and secondary secondary shoots grow from the secondary shoot. Only one secondary shoot at the top of the secondary shoot is left, and the rest is wiped out. Wipe off all the tendrils on the new and secondary shoots.

Promptly tie the new shoots to the iron wire and make them grow upright. The spacing between new shoots should be uniform, with 16-20 new shoots per square meter of the shelf surface, and the rest should be wiped off. Timely remove overly dense weak branches, diseased branches, residual branches, and withered old branches, reduce nutrient consumption, and concentrate on supplying fruit enlargement.

2. Ear management

Leave ears according to the growth trend of new shoots. The general retention method is strong, medium, and weak, with no retention. If there are three ears in a new shoot, it is necessary to remove 1-2. If the ear is not pinched before flowering, 1/5-1/4 of the ear tip can be pinched off. Timely remove diseased, residual, and deformed fruits. Promote the growth and weight gain of the remaining fruit ears and grains, and improve yield and quality. At the same time, timely bagging treatment is also necessary.

3. Intertillage and weeding

Timely intercropping and weeding should be carried out to eliminate weeds, loosen soil, increase soil temperature, reduce nutrient consumption, promote root growth downwards, and facilitate drought resistance, flood resistance, and nutrient absorption.

4. Fertilizer and water management

The period of grape fruit enlargement is the period of maximum fertilizer and water requirements throughout the entire growth period. This period should have comprehensive nutrition and pay attention to a reasonable fertilization ratio. Fertilization requires a large amount of elements, mainly nitrogen and potassium fertilizer, and a small amount of phosphorus fertilizer. During this period, the key is to promote cell division, and it is also necessary to use Baiweide Shuoguo 1 seaweed calcium and magnesium to supplement medium amounts of elements such as calcium and magnesium.

The period of fruit enlargement is also the peak period of root growth, and a well-developed root system is conducive to nutrient absorption and promotes fruit enlargement.

To develop the grape root system and absorb nutrients effectively, use the Baiweide Black Yuanjia Microbial Agent. The Baiweide Black Yuanjia Microbial Agent is rich in effective live bacteria, which not only improves the soil but also helps plants absorb more effective nutrients from the soil. At the same time, it promotes rooting, promotes flowering, promotes fruit swelling and color transformation, stimulates plant potential, improves crop immunity, and increases yield and income.

5. Prevention and control of pests and diseases

The period of grape fruit enlargement is the season of high temperature and rainy weather, as well as the season of frequent diseases. Common occurrences are downy mildew and white rot, and timely protection should be taken!
