Embodiment 1

[0037] According to the following components by weight percentage ratio: chitosan powder 20%, bamboo charcoal powder 60%, oyster shell powder 20%.

[0038] Location: The Strawberry Base in Xinnong Agricultural Materials in Weihai Economic Zone, Shandong Province

[0039] Area: 1.8 mu of strawberry field

[0040] Greenhouse type: greenhouse

[0041] The basic condition of the soil before implementation: the average pH value is 4.2. The average EC value was 0.73. In order to detect the soil of the greenhouse as a whole, take the average value.

[0042] Implementation method: Sprinkle the prepared above-mentioned formula evenly on the strawberry seedlings and the soil surface. The material used is 15KG.

[0043] On November 18, 2011, the second implementation was carried out. The method this time is to sprinkle the above-mentioned materials evenly on the roots of each strawberry in a circular manner. The material used is 20KG.

[0044] On December 4, 2011, the third imple...

Embodiment 2

[0054] According to the following components by weight percentage ratio: chitosan powder 10%, bamboo charcoal powder 30%, oyster shell powder 60%. After the preparation, the changes of various values ​​after application are as follows: the pH value of the soil increased from the original 4.1 to 5.0, an increase of 0.9. The EC value changed from 0.73 to 0.70, a decrease of 0.03. The sugar content of strawberries rose from 9.2 degrees to 9.6 degrees, an increase of 0.4 degrees. The incidence of strawberry anthracnose has been reduced by 65%, root rot has been reduced by 50%, powdery mildew has been reduced by 55%, and the yield has increased by 9%.

Embodiment 3

[0056] According to the following components by weight percentage ratio: chitosan powder 30%, bamboo charcoal powder 40%, oyster shell powder 30%. After the preparation, the changes of various values ​​after application are as follows: the pH value of the soil increased from the original 4.1 to 4.8, an increase of 0.7. The EC value changed from 0.73 to 0.68, a decrease of 0.05. The sugar content of strawberries rose from 9.2 degrees to 9.8 degrees, an increase of 0.6 degrees. The incidence of strawberry anthracnose has been reduced by 81%, root rot has been reduced by 73%, powdery mildew has been reduced by 65%, and the yield has increased by 15%.

Abstract

The invention relates to a chitosan mixture and an application thereof in preventing and treating strawberry anthracnose and solves the technical problem that pesticides are used for preventing from diseases at present. The chitosan mixture contains following components in percentage by weight: 10%-30% of chitosan powder, 30%-60% of bamboo charcoal powder and the balance of oyster shell powder. The chitosan mixture can be widely applied to preventing and treating the strawberry anthracnose.

Description

technical field [0001] The invention relates to a mixture and its application, in particular to a chitosan mixture and its application in preventing and treating strawberry anthracnose. Background technique [0002] Strawberry anthracnose is one of the main diseases of strawberry seedlings. It is a common fungal disease and is called cancer of strawberry. [0003] The formation etiology and harm of strawberry anthracnose: Grasshopper anthracnose belongs to the fungus of the subphylum Deuteromycota. The fungus overwinters as conidia in the diseased tissue or in the diseased debris on the ground. In the field, conidia are spread by means of rainwater, operating tools with bacteria, diseased leaves, and diseased fruits. The most suitable temperature for pathogen infection is 28-32°C, and the relative humidity is above 90%, which is a typical high-temperature and high-humidity type pathogen. After late May, when the temperature rises above 25°C, strawberry stolons or young ti...
