Fruit expansion skills of Hutai No. 8

Hutai No. 8 needs to choose a suitable fertilizer to expand the fruit. Qibao and Bumeiling are all effective products. The expansion treatment should be carried out 15 days before germination, which can deepen the management of fertilizer and water.

Fruit expansion skills of Hutai No. 8

The main results are as follows: 1. The performance of Qibao is better than that of domestic gibberellin, and its concentration varies greatly according to variety, time and effect. The commonly used concentration is generally 5000ml 40000 times, and the concentration of spraying wet whole plant 15 days before flowering is 3000ltel 40000 times. The main function is to accelerate the growth of branches and leaves, elongate inflorescences and remove seeds. After physiological flower drop, the concentration is 5000 times, 10000 times and 20000 times, respectively, so that the flowers are generally not used before falling flowers, because the general flowering of grapes will not be too neat, which will lead to the appearance of large and small grains. In addition, it should be noted that the concentration of seedless grapes is generally less than that of seedless grapes.

2. Both Bao Mei Ling and streptomycin can reduce the thickening and softening of fruit stalks, especially streptomycin can inhibit lateral thickening and reduce the cork and brittleness of fruit stalks, but the content of gibberellin accounts for half of the total active ingredients of Bao Mei Ling. It can protect flowers and fruits, improve quality, promote early ripening and promote flower bud differentiation, so the use of Bao Mei Ling has more advantages than streptomycin. The commonly used concentration of bomeiling is 8000 times, and the effect of mutual superposition of the longitudinal diameter of fruit is better than that of Danqibao after the mixture of bomeiling and Qibao, especially 4 days after the fall of grape, spraying all stems and leaves and flower spikes with Bomelin alone can not only lengthen the ear, remove seeds and promote seedlessness, but also promote flower bud differentiation. For long-seeded grape varieties such as White Chicken Heart, Golden finger, etc., it will be better to mix Qibao and Baomeiling.
