Poor fruit size and slow fruit swelling? These management measures must be in place.

The swelling period of young grapes is a very important stage in the growth cycle of grapes. Whether the management during this period is in place directly affects the yield and of grapes in the current year, so where is the focus of management?

一. Branch management After the new shoots grow out, one week before flowering, pinch the buds 4 leaves in front of the flower cluster the fruit branch. For the secondary shoots growing on the new shoots, only keep one secondary shoot at the top of the new shoot, and remove all the rest. Pinch secondary shoots when they grow to 5 leaves, and only keep one secondary shoot at the top of the secondary shoots, and remove all the rest. All tendrils on the shoots and secondary shoots should be removed. Bind the new shoots to the wire in time to make them grow upright. The spacing of new shoots should be uniform, with 1-20 new shoots per square meter of trellis, and all the rest should be removed. Thin out the weak branches, diseased branches, damaged branches and dry branches in time to reduce nutrient consumption and concentrate on supplying the fruit with nutrients for expansion.

二、Grape bunch management Retain bunches based on the growth of the new shoot. The general method is to keep one for each strong or medium new shoot and none for weak ones. If a new shoot has three bunches, it is necessary to remove one or two. For those that did not the tips of the bunches before flowering, pinch away 1/5-1/4 of the bunch tips at this time. It is also necessary to remove diseased damaged, and deformed fruits in a timely manner. Promote the enlargement and weight gain of the retained bunches and berries to increase yield and quality. In addition, it is necessary to carry out timely bagging treatment. 1. Shoot management After the new shoot has grown out, one week before flowering, pinch the shoot at the leaf from the front of the bunch on the fruit-bearing branch. For the secondary shoots that grow out of the new shoot, only keep the top one, and remove the others. Pinch the secondary shoots when they have five leaves, and only keep the top one of the secondary shoots that grow out of the secondary shoots, and remove all the. All tendrils on the new shoots and secondary shoots should be removed. Tie the new shoots to the wire in time to make them grow upright. The spacing new shoots should be uniform, with 16-20 new shoots per square meter of trellis, and all the others should be removed. Thin out the dense branches, diseased branches, damaged branches, and dry old branches in time to reduce nutrient consumption and concentrate on supplying the fruit for expansion.

2、 Grape bunch management Retain bunches based on the growth of the new shoot. The general method is to keep one strong, medium, and one weak bunch. If a new shoot has three bunches, it is necessary to remove one or two. For those that have not pinched the tips of theches before flowering, pinch off 1/5-1/4 of the bunch tip at this time. It is also necessary to promptly remove diseased, damaged, and fruits. Promote the growth and weight gain of the retained bunches and berries to increase yield and quality. At the same time, it is also necessary to promptly carry out bag treatment. 三、Intercultivation and weed removal Intercultivation and weed removal should be carried out in a timely manner to eliminate weeds, loosen soil, increase soil temperature, reduce nutrient consumption, promote root growth downward, and help resist drought, waterlogging, and nutrient absorption.

四、Fertilization management The berry swelling period is the period with the highest demand for nutrients and water throughout the growth. During this period, nutrition should be comprehensive, and attention should be paid to a reasonable fertilization ratio. Fertilization should mainly consist of nitrogen and potassium fertilizers, a small amount of phosphorus fertilizer. The key during this period is to promote cell division, and it is also necessary to use Haifa Calcium and Magnesium from Biow to supplement calcium and magnesium and other secondary nutrients. The berry swelling period is also the peak period for root growth. A developed root system is beneficial for nutrient absorption and berry swelling. To promote the development of grape root systems and improve nutrient absorption, use Biowet Hei Yuanjia Microbial Agent. Biowet He Yuanjia Microbial Agent is rich in effective live bacteria, which can not only improve the soil but also help plants absorb more effective nutrients from the soil while promoting root growth, excessive growth, promoting flowering, and promoting berry swelling and color change. It can also stimulate plant potential, improve crop immunity, and increase yield and income. 五、Disease and pest control The berry swelling period is during the high-temperature and rainy season, which is also the season with a high incidence of diseases. The common that occur are downy mildew and white rot. It is necessary to take timely preventive measures!
