Red grape high quality and high yield technology

Red grape is an ideal grape variety, which is favored by consumers and the price is relatively high. When red is planted in northern China, it is often difficult to suffer from frost damage, which affects the yield and quality, and becomes a problem in the production of fruit farmers. Here, we recommend a biotech product from Germany, “Bibao”, which is the general agent of Beijing Chenghe Jiaxin Agricultural Materials Trading Co., Ltd..

In 2010, we carried out experimental applications on red grape, and achieved remarkable results. On March 10, 2010, we tested in the four-year-old red-raised vineyard of Li Manshun, a villager in Shangchao Village, Ronghe Town, Wanrong County, Shanxi Province (acreage of 3 mu, plant spacing of 1 m × 2 m): before transplanting “Bi-protection” was immersed for 2,000 times in 8000 times, and was damaged by the 3°C night frost on April 12-13. After planting, it was sprayed on April 14th with “Bi-protection” 10000 times. The first investigation was conducted on April 20th. After the frost, the new shoots with less than 2cm germination in the control area were severely frozen and failed to recover. The shoots died dry. The second time on July 30, the plant growth was investigated. Leaf size, shoots and winter bud development. The test results show that in the area where the northern grape producing area is frequent in the late frost, the roots of the “Baihu” 8000 times liquid can be used to effectively prevent the late frost and improve the survival rate of planting by 67.8%. After being frozen, it can be quickly sprayed with 10,000 times on the ground, and the plant growth potential can be quickly restored. The tree is stable and strong, the summer shoots are long and not long, the winter buds are full, the branches are mature, and the leaves are dark green.

Therefore, it is recommended that the grape producing areas in the north be tested and applied to apply this product. While effectively solving the natural disasters, it will ensure the success of the construction of a garden and lay the foundation for the second year of high-quality and high-yield production.

For the red-raised mature trees, on the April 5th sprouting stage, the tree was sprayed with “Baihu” 20,000 times liquid to prevent night frost. After suffering from a rare frost (minus 3°C) on April 12-13, on April 15th, “Baihu” 8000 times liquid was used to resist freezing to restore the tree; before the flowering on June 1st, spray “Bijian” 20000 times the liquid to increase the fruit setting rate; on July 1st, the vinegar fruit is inflated with "Bai" 20,000 times spray. The test results show that before the germination, the frost will be sprayed with “200,000 times of liquid” and 74.3% of the frozen after germination, which can effectively prevent night frost damage. Spraying “Baihu” 8000 times solution after frost can quickly restore the tree potential, restore the growth of new shoots, maintain the normal production of the vineyard, and be protected from natural disasters.

The test proves that spraying the “Bi-protection” 20,000 times liquid before the flowering of the red grape can lengthen the inflorescence, increase the fruit setting rate by 35%, and promote the beauty of the ear. Spraying “Bi-protection” 20,000 times solution after flowering can promote fruit expansion and enhance the resistance of the tree, especially to resist high temperature of 38 °C, resist drought, strong tree, new shoot growth and not long, maturity Well, winter buds are full and the effect of increasing yield is obvious.

Therefore, it is recommended that the northern grape producing areas in China should effectively prevent the natural disasters such as night frost and ensure the high quality and high yield of the vineyards in successive years. It is advisable to test and apply the composite natural plant source product “Bibao”. It can help fruit farmers produce more and better organic green grapes, and can achieve low input and high output.
