A green prevention and control method of edible rose powdery mildew combined with physical means

Abstract

The invention relates to the technical field of rose planting, in particular to a green prevention and control method for powdery mildew of edible roses combined with physical means, comprising the following steps: S1, soil preparation: removing weeds and disinfecting the soil; S2, early stage of growth: Apply organic fertilizer and compound microbial fertilizer containing Bacillus subtilis; S3, growth period: water once every 3-5 days in spring, once a day in summer, and spray water on the leaves when the temperature is too high; S4, flowering period: adapt to the bud stage Supplement phosphorus and potassium fertilizers, because the flowering stage consumes a lot of nutrients and water; S5, post-flowering stage: plant pruning is required in the late flowering stage; S6, winter dormancy stage: use lime-sulfur mixture with high efficiency, low toxicity and low cost for disease control. According to the occurrence of diseases in the growing period of roses, the method proposed by the invention scientifically and rationally uses microbial agents and physical prevention and control, and uses low-risk pesticides to ensure the ecological cleanliness of the garden and increase the yield of rose flowers.

Description

technical field [0001] The invention relates to the technical field of rose planting, in particular to a green prevention and control method for edible rose powdery mildew combined with physical means.

Problems solved by technology

The 'Mohong' variety has poor disease resistance, and powdery mildew occurs frequently, and the damaged parts are mainly leaves and young flower buds. Black spot disease also occurs frequently during the rainy season. If necessary, broad-spectrum antibacterial agents can be used to control the disease before flowering. Such as Disenmengzinc, chlorothalonil, carbendazim, thiophanate, etc., but after using the medicine, it is easy to cause the increase of the drug resistance of the bacteria and the recurrence of the disease, and improper application can lead to problems such as pesticide residues in the harvested flowers. With the emergence of agricultural products, the prevention and control methods should also be innovated, and the use of pollution-free methods for prevention should be advocated.
