Problems solved by technology

However, due to the repeated use of the nutrient matrix vermiculite and some other reasons, soil-borne diseases such as damping-off, standing blight, withering, root rot, bacterial wilt, etc. occur from time to time in the production process of original potato seeds. To a certain extent, it affects the production quality, cost and economic benefits of the original seed potato
At present, in potato production, carbendazim wettable powder ...

Abstract

The invention relates to a seedbed disinfectant and especially relates to a seedbed disinfectant for controlling soil-borne diseases of seed potato. The seedbed disinfectant solution is characterized by comprising components of, in per kilogram, 1.05-2.1g of metalaxyl. Hymexazol, 0.5-0.75g of chitin, 0.35-0.5g of S-ABA, 0.1-0.2g of farm-oriented streptomycin and the balance of water. The preparation method includes steps of: mixing the above amount of raw materials; stirring; blending well; and diluting until a liquid medicine content in per square meter of seedbed (vermiculite) reaches 6.0 kg. The usage method comprises steps of: spraying the disinfectant on old vermiculite used for seed potato production to reach a liquid medicine amount of 6.0kg/m<2>; covering with a plastic film to sterilize for 3 days; revealing the film and airing for 10 days; then carrying out cuttage on the potato virus free propagation seedlings. The disinfectant of the invention not only can kill pathogenic fungi and bacteria, mitigate harms of soil borne diseases, such as damping off, seedling blight, droop, root rot and green wilting in seed potato production, but also can enhance crop biological activity and immunity, promote crop growth, and has disease resistance, mithridatism, root-knot nematode resistance, cold resistance and saline-alkali resistance.

Description

technical field [0001] The invention relates to a seedbed disinfectant, in particular to a preparation method and a use method of a seedbed disinfectant for preventing and treating soil-borne diseases of original potato seeds. Background technique [0002] Potato is a food and vegetable crop with high yield and economic benefits, but potato is not suitable for double cropping, otherwise it will cause more fungal and bacterial diseases in the soil, nutrient imbalance, and acid-base imbalance. Especially in the process of producing seed potatoes in greenhouses or net rooms, that is, the original seed and the original seed, problems such as soil-borne diseases and soil physical and chemical properties in potato seed production tend to be aggravated due to heavy cropping, resulting in a decline in yield and quality. Affecting export sales, the loss is relatively large. For this reason, the net room has been used to replace the soil in production, but this method has a large amo...
