Problems solved by technology

In the middle and late stages of the disease, the roots of the plants gradually rot and turn black, and the aboveground parts wither and die, resulting in a decrease in the production of medicinal materials, a significant decrease in the appearance quality of medicinal parts and the content of medicinal active ingredients, and even lose their medicinal or commercial value

Example Embodiment

[0009] Example 1: High altitude areas (3000 meters -3500 meters)

[0010] (1) Site selection and site preparation

[0011] Choose a sandy loam that is sunny, deep and fertile, well-drained, and soil pH is about neutral for planting. Before planting, combine with land preparation, and apply 5000kg of fully decomposed farmyard manure per acre. The land preparation requires a box height of 15cm, a box width of 120cm, and a trench width of 35cm.

[0012] (2) Scientific fertilization

[0013] Diseased plants found during the planting process should be removed in time, planted once every two years, after planting and harvesting, rotation or rotation is required. After the first year of cultivation and the second year of spring seedlings, topdressing should be combined with cultivating and weeding to moderately control the amount of nitrogen fertilizer. , Increase the application amount of phosphate fertilizer and potash fertilizer, apply 8kg nitrogen fertilizer, 15kg phosphate fertilizer a...

Example Embodiment

[0016] Example 2: Mid-altitude area (2000m-3000m)

[0017] (1) Site selection and site preparation

[0018] Choose a sandy loam that is sunny, deep and fertile, well-drained, and soil pH is about neutral for planting. Before planting, combine with land preparation, and apply 5000kg of fully decomposed farmyard manure per acre. The land preparation requires a box height of 20cm, a box width of 100cm, and a trench width of 50cm.

[0019] (2) Scientific fertilization

[0020] Diseased plants found during the planting process should be removed in time, planted once every two years, after planting and harvesting, rotation or rotation is required. After the first year of cultivation and the second year of spring seedlings, topdressing should be combined with cultivating and weeding to moderately control the amount of nitrogen fertilizer. , Increase the application amount of phosphate fertilizer and potash fertilizer, apply 5kg nitrogen fertilizer, 10kg phosphate fertilizer and 10kg potash ...

Abstract

The invention provides an integrated control method of radix saussureae lappae root riot, which comprises the following steps that: (1) variety selection: an excellent radix saussureae lappae seed with quite good disease resistance is selected; (2) land selection and leveling: sandy soil which has 2000 to 3500m elevation, faces to the south, has deep fertile soil layer, good water drainage and neutral pH value is selected to plant the seed, and when cropping the land, an alternated internal term of above 2 years is selected; 2500 to 5000kg of farmyard manure is applied to each mu of land, the box management height is 15 to 20cm, the box width is 100 to 120cm, and the width of trenches between boxes is 35 to 50cm; (3) scientific fertilization: after a seedling emerges in the spring of a first year and the spring of a second year, fertilizer is supplemented for once respectively by integrating with cultivation and weeding; and (4) chemical control: before sowing, carbendazol wettable powder or thiophanate methyl wettable powder are used to soak the seed. In the early period of the disease, the carbendazol wettable powder, the thiophanate methyl, hymexazol wettable liquor or sandofan m8 wettable powder diluent are used to irrigate the root.

Description

technical field [0001] The invention relates to a method for comprehensive prevention and treatment of root rot of A. argentina. Background technique [0002] Yunmuxiang is also known as Muxiang and Guangmuxiang. Included in "The Pharmacopoeia of the People's Republic of China" 2005 edition one 41, 42 pages. It is the root of Asteraceae (Aucklandia lappa Decne.). Yunmuxiang is an authentic medicinal material in Yunnan Province. It was originally produced in India, and was later introduced to my country and successfully cultivated in Lijiang, Yunnan. Root rot is one of the diseases with the most widespread incidence and the greatest impact on yield in the cultivation of basilica, and it mostly occurs in summer with high temperature and high humidity. In the early stage of infection, dark brown lesions appear on the roots or stem bases, the leaves above the ground appear dull, and the plants appear wilting symptoms. In the middle and late stages of the disease, the roots o...
