How to improve the fruit setting rate of the latest Jufeng grape
Jufeng grape is an European-American hybrid variety, which has strong adaptability and disease resistance. it is one of the main grape varieties at present, and it has a wide planting area all over the world. However, many fruit growers say that their fruit setting rate is low, so how to improve the fruit setting rate of Jufeng grape? Let's get to know it.
First, the reasons affecting the fruit setting rate of Jufeng grape.
There are many reasons that affect the fruit setting rate of Jufeng grape. the first is the temperature. The suitable temperature in the flowering period of Jufeng grape is 26-30 degrees. If it is higher than 30 degrees for a long time, it will lead to serious flower drop and lead to the decrease of fruit setting rate. In addition, the tree is too strong will also affect its fruit-setting rate, the more exuberant the tree, the more serious its flower drop, in addition, a little too dense branches will also lead to fruit drop easily. Pruning after anthesis will also lead to fruit drop, gray mold and brown blight in the disease will also affect its fruit setting rate, too moist soil will also lead to serious fruit drop, there are many reasons for its low fruit setting rate.
Second, how to improve the fruit setting rate
1. Control the tree potential
For the overflourishing plant, it is necessary to take measures to control the growth, and control its new shoot below 70 cm, which is beneficial to fruit setting. If the length of the new shoot before flowering reaches more than 80 cm, its fruit setting rate will be relatively low. In addition, it is necessary to control fertilizer and water in the growth of new shoots, so as to avoid the vigorous growth of new shoots, and topdressing compound fertilizer and potassium disulfate after fruit setting, which can promote fruit growth and reduce fruit drop.
2. Pick the heart
Heart-picking can be carried out in about a week of florescence, which can concentrate nutrition and inflorescence, which is beneficial to fruit setting, and attention should be paid to the method of heart-picking. Generally, weak inflorescences leave 5-6 leaves for heart-picking, while prosperous inflorescences leave 3-5 leaves for heart-picking.
3. Spraying zhuangsu
Zhuangzhuangsu can be sprayed in about a week of florescence, which can significantly improve the fruit setting rate. The commonly used bodybuilder is metagonium water agent, generally 15 mg per bottle of water for 15 jin. Growth can increase the concentration to 12 jin per bottle.
4. Control output
Grape flower thinning and fruit thinning can reduce plant nutrient consumption, avoid excessive nutritional burden, premature senescence, and uniform vegetative growth and reproductive growth of grape plants. However, controlling the yield can obviously improve the fruit setting rate and quality of grapes, generally controlling the yield of about 3500 jin per mu, requiring 20-25 effective leaves per cluster of fruits, 3-5 leaves above the ear do not retain the leaves of the auxiliary tip, and leaves above the fifth leaf begin to retain the leaves of the auxiliary shoots. Each ear retains about 40 grains.
The above is the introduction of how to improve the fruit setting rate of Jufeng grape. I hope it can help you. If you want to know more about it, please follow us.
