Embodiment 1

[0062] A comprehensive control method for notoginseng powdery mildew, comprising the following steps:

[0063] 1. Ecological governance

[0064] ((1) Apply Difulai fertilizer for greenhouses. The specific method of using fertilizer for greenhouses is as follows: mix 200ml of fertilizer for greenhouses with 50kg of water, mix the fertilizer for greenhouses with water and spray it on the ground surface ;

[0065] (2) Apply Wo Yiduo, add HYT-A150ml and HYT-B350ml in 15 liters of water and stir evenly, place it at room temperature for 2 days, add HYT-C80g, leave it for another day, add water to 250 kg, stir well and then water the roots , used 2-4 times throughout the growth period;

[0066] (3) apply traditional Chinese medicine micro-fertilizer one month before the autumn flowers bloom, and the traditional Chinese medicine micro-fertilizer is calculated in parts by weight, consisting of 110 parts of medical stone powder, 3 parts of Ginkgo biloba extract, 10 parts of Artemisia ...

Embodiment 2

[0087] Substantially the same as Example 1, the difference is: 400ml of fertilizers are used for per mu of ground,

[0088] The dosage of Woyiduo per mu is 180ml of HYT-A, 250ml of HYT-B and 120g of HYT-C;

[0089] Use 90kg of decomposed organic fertilizer per mu.

[0090] The powdery mildew of notoginseng is effectively prevented by adopting the control method of the invention, and the output of notoginseng is increased by more than 30% compared with the comparative example.

Embodiment 3

[0092] Substantially the same as Example 1, the difference is that 300ml of fertilizer for greenhouses is used per mu of land,

[0093] The dosage of Woyiduo per mu is 200ml of HYT-A, 300ml of HYT-B and 100g of HYT-C.

[0094] Use 100kg of decomposed organic fertilizer per mu.

[0095] The powdery mildew of notoginseng is effectively prevented by adopting the control method of the invention, and compared with the comparative example, the output of notoginseng is increased by more than 31%.

Abstract

The invention relates to a prevention and treatment method for powdery mildew of panax notoginseng, comprising following steps: 1. ecological management: 1) applying greenhouse type fertilizer of Difulai with amount from 200 to 400 milliliters per Mu; 2) during the whole growth period, applying fertilizer of High Yield Technology from 2 to 4 times with amount as follows: HYT-A 200 to 250 milliliters per Mu, HYT-B 250 to 350 milliliters per Mu, and HYT-C 100 to 120 grams per Mu; 3. applying trace fertilizer of Chinese medicine one month before autumn blooming with application amount from 20 to 25 grams per Mu; 2. agricultural prevention and treatment; 3. biological prevention and treatment; 4. biological control; 5. physical prevention and treatment; 6. chemical prevention and treatment. By use of the ecological management, agricultural prevention and treatment, biological control, physical prevention and treatment and chemical prevention and treatment, the morbidity of powdery mildew of panax notoginseng is greatly reduced and quality and quantity of panax notoginseng are increased.

Description

technical field [0001] The invention relates to a comprehensive control method for notoginseng powdery mildew, belonging to the field of notoginseng pest control. Background technique [0002] Symptoms of notoginseng powdery mildew: yellow spots appear on the damaged leaves at the beginning, then irregular yellow spots appear on the front of the leaves, white powdery matter appears on the back of the leaves, and "gray discs" appear when the flower disc is killed. Small gray spots appeared on the stems at the initial stage of damage, which expanded into larger gray spots. [0003] Early stage of onset: Powdery mildew spreads to Panax notoginseng through airflow to cause onset. When the temperature in the garden is between 10-26°C, relative humidity is 65-85%, and accompanied by hot wind blowing in dry season, the onset is more serious. In addition, Panax notoginseng is densely planted, the soil quality is fertile or nitrogen fertilizer is applied more, and the shady seven ga...
