Red grape is currently an ideal grape variety, which is favored by consumers and the price is relatively high. Planting in northern China is often due to the vulnerability to frost, affecting grape yield and quality, and it has become a problem for fruit growers. Here, a farmer friend is recommended a biotechnology product from Germany, which is the general agent of Beijing Chengyu Jiaxin Agri-products Trading Co., Ltd., “Bianhuâ€. It is a new compound plant growth regulator that can induce plants to improve stress resistance. A large number of production trials have proved that “Baihu†can not only eliminate inhibitory phytotoxicity caused by pesticides, fertilizers, herbicides, and artificial hormones, but also promote root growth, increase production and quality, achieve water and fertilizer conservation, and reduce production costs. Increase the effect of income. In 2010, we carried out trial applications on red grape and achieved significant results. On March 10th, 2010, we used the “Bi-Hua†8000 before transplanting in the 4-year-old red vineyard of Li Manshun, a villager of Shangchao Village, Ronghe Township, Wanrong County, Shanxi Province (with an area of ​​3 mu and a row spacing of 1.2m). The roots were soaked for 12 hours. After being frost-damaged at minus 3°C on April 12-13, they were sprayed on the ground on April 14th with the “Baihuo†10,000-fold liquid. The first investigation was conducted on April 20th. After being frosted, the shoots in the control area that had sprouted less than 2 cm were severely frozen and failed to recover. The branches and shoots died of dryness; the second time on July 30, the plants were surveyed. Leaf size, new shoots, winter bud development. The test results show that in areas of late-season grape growing in northern China, “bi-guard†8000 times liquid dip root can effectively prevent late frost and increase the survival rate of plant by 67.8 percentage points. After being chilled, “Bi-Yuan†sprayed 10,000 times on the ground to quickly restore plant growth potential, and the tree vigor is stable and strong, but the summer shooter grows without being too long, the winter buds develop satisfactorily, the branches mature well, and the leaves are dark green. Big and fat. Therefore, it is recommended that the grape production areas in the north should conduct trial demonstrations and application of the product. While effectively solving natural disasters, it is also necessary to ensure the success of a successful garden construction and the strong and neat and tidy seedlings. It also lays a solid foundation for the second year of high quality and high yield. The mature tree of red grape was budded on April 5 and the tree was sprayed with “Bi-Yuan†20,000-fold liquid to prevent late frost, and on April 12-13 after experiencing historically rare frost (-3°C below zero). On April 15th, “Baihu†8000 times liquid was used to freeze and restore the tree vigor; before flowering on June 1st, spraying “Bihuo†20,000 times liquid increased the fruit setting rate; on July 1, the young fruit was enlarged. During the period, "Bi-care" sprayed 20,000 times. The test results show that before the onset of late frost, spraying "Bai-protection" 20,000 times, 74.3% after freezing buds to reduce frost damage can be effectively prevented. Spraying “Bi-Pro†8000 times after frost can quickly restore tree vigor, restore shoot growth, maintain normal vineyard production, and protect against natural disasters. Tests have shown that spraying “bi-guard†20,000 times before the flowering of the red grape can lengthen the inflorescence, increase the fruit setting rate by 35 percentage points, and promote the appearance of the ear. Spraying “Bi-Yuan†20,000 times after flowering can promote fruit enlargement and enhance tree stress resistance, especially against 38°C high temperature, drought resistance, strong tree vigor, new shoot growth but not long, mature The degree is good, winter buds are fully developed, and the yield increase effect is obvious. Therefore, it is suggested that in order to effectively prevent natural disasters such as late frost and ensure natural disasters such as late frost, the northern region of China's grape production region may wish to test and demonstrate the application of the complex pure natural plant source product “Bia-Yue†to produce more and better organic green grapes. Can achieve low input and high output.
