Embodiment 1

[0032] 1. Test materials

[0033] The experiment was carried out in the grape planting base of Hengcun, Jincheng Street, Lin'an City in 2017, with the main grape variety 'Yongyou No. 1' in Zhejiang Province as the test material. The grape planting area of ​​the base is more than 30 mu, the terrain is flat, the soil fertility is balanced, and the soil quality is sandy loam. The age of the plants is 8 years, the spacing between the plants is 1 m, and the row spacing is 2.6m. Plant a row with 25 plants in each row. The growth vigor of each test plant was relatively consistent, and the cultivation and management level was good.

[0034] 2. Disinfection and clearing the garden at the initial stage of planting

[0035] From late February to early March, when the spring temperature is stable at 8-10°C, cut off the sick and residual branches, and fix the branches on the grape trellis. Then use a mixture of 95% mineral oil (diluted 200 times), 1% azadirachtin (diluted 1500 times) a...

Embodiment 2

[0069] 1. Test method

[0070] The test was carried out at the same test base as in Example 1 in 2018, and the test materials and the previous disinfection treatment of the garden were the same as in Example 1. The components of the plant resistance inducer used in the treatment of inducing resistance adjustment are also the same as in Example 1, but the biological pesticides or chemical pesticides used in combination are different.

[0071] Three treatments were set up in the test, which were two plant resistance inducer treatments (specifically, as shown in treatment groups 3 and 4), and sprayed once every half a month to avoid medication during flowering, and the grapes were sprayed before the grapes matured. Ended in mid-July, sprayed 7 times in total, and used in conjunction with biological pesticides or chemical pesticides; comparison group 2 was conventional chemical pesticide control, sprayed 11 times in total according to the perennial disease control period. See Tab...

Abstract

The invention discloses application of stropharia rugosoannulata polysaccharide, a resistance inducer and a grape cultivation method. Research finds that when the stropharia rugosoannulata polysaccharide is prepared into a resistance inducer for grape cultivation, the disease resistance of grape plants can be improved, pesticide use is reduced, the prevention and treatment effect on grape downy mildew and grape anthracnose diseases is good, the yield and quality of grape fruits can be improved, and the stropharia rugosoannulata polysaccharide is safe to grapes under the treatment concentration. The stropharia rugosoannulata polysaccharide can be independently prepared into a resistance inducer and can also be compounded with other components such as amino-oligosaccharin, calcium amino acidchelate and magnesium amino acid chelate, and after compounding, the prevention and treatment effect of the inducer can be further improved.

Description

technical field [0001] The invention relates to the technical field of viticulture, in particular to the application of stropharia polysaccharide, a resistance inducer and a viticulture method. Background technique [0002] Grape is one of the three major fruits in the world, and it is also an important economic crop in my country. During the whole growth process, it is easy to suffer from a variety of pathogenic bacteria, among which grape downy mildew, grape anthracnose, grape white rot, etc. are the most common, and the current control methods are mainly chemical control. Although the use of chemical pesticides can effectively prevent and control grape diseases, it also increases pesticide residues, food safety risks and ecological environment hazards. [0003] Studies have shown that plant resistance inducers can activate the molecular immune system in plants, so that plants can acquire systemic resistance to avoid diseases or reduce the occurrence of diseases, and at t...
