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 u

Example Embodiment

[0028] Embodiment one

[0029] A green prevention and control method for edible rose powdery mildew combined with physical means, comprising the following steps:

[0030] S1. Soil preparation:

[0031] Remove weeds and disinfect the soil, apply 900kg / mu of undecomposed organic base fertilizer, sprinkle 50kg / mu of lime nitrogen, deeply plow the soil 25cm to make it fully mixed, irrigate and cover with plastic film, in seasons with sufficient light and high temperature Seal it for one month. After peeling off the film, let the soil expose to the strong light and let it dry naturally. If it is planted in a greenhouse container, the cultivation medium should be decomposed culture soil. The depth of fully loosened soil should be 13cm, and medical ultraviolet disinfection lamp UVC irradiation for 30 minutes to thoroughly sterilize the soil;

[0032] S2. Early growth stage:

[0033] Organic fertilizers and compound microbial fertilizers containing Bacillus subtilis can be applied,...

Abstract

The invention relates to the technical field of rose planting, in particular to a green prevention and control method for edible rose powdery mildew by combining with a physical method. The method comprises the following steps of S1, soil preparation, wherein weed removal and disinfection treatment are carried out on soil; S2, the earlier period of growth, wherein an organic fertilizer containingbacillus subtilis and a compound microbial fertilizer can be applied; S3, the growth period, wherein watering is carried out once every 3-5 days in spring, watering is carried out once every day in summer, and water is sprayed onto the leaf surface when the temperature is too high; S4, the flowering period, wherein a phosphate and potash fertilizer is appropriately supplemented in the bud period due to the fact that a large number of nutrients and water are consumed in the flowering period; S5, the later period of flowering, wherein plant type trimming is carried out in the later period of flowering; S6, the dormancy period of winter, wherein efficient low-toxicity low-cost lime sulphur is adopted for disease control. According to the adopted method, on the basis of disease occurrence situation in the rose growth period, a microbial agent and physical prevention and control are used scientifically and reasonably, and low-risk pesticides are used to ensure the ecological cleanliness ofgardens and increase the yield of rosa chinensis.

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. Background technique [0002] Edible roses generally refer to Rosaceae ( Rosaceae ) Rosa ( Rosa L.) Rose ( Rosa rugasa ), Chinese rose ( Rosa chinensis ),rose( Rosa sp. ) is a general term for some of the edible varieties. my country's roses are native to the north, have a long history of cultivation, and are currently planted all over the country.
