Abstract

The invention relates to preparation and application methods of a special fertilizer for continuous-cropping isatis indigotica, belonging to preparation and application of fertilizers. The preparation method comprises the following steps of: mixing dairy manure, chicken manure, corn stalk powder, corn flour and organic material decomposing inoculants, adding water and stirring, preserving moisture and fermenting; drying and smashing a fermented mixture material, adding humic acid powder and bentonite powder, and continuously drying to obtain a main material; uniformly mixing corn stalk segments, the corn stalk powder, sorghum stalk powder, calcium superphosphate and potassium sulphate to prepare an auxiliary material; and uniformly mixing the main material with the auxiliary material by the weight ratio of 1:(1-4) to prepare the special fertilizer for the continuous-cropping isatis indigotica. The application method is characterized in that 1500-2600kg of the special fertilizer for the continuous-cropping isatis indigotica is applied per 667m<2> and ploughed under the deep soil of 15 centimeters to 30 centimeters. In the invention, the nutrients required for the growth of the isatis indigotica are ensured, and meanwhile, organic matters, beneficial bacteria and the like are added for improving the rhizosphere environment according to the growth characteristics of the isatis indigotica, therefore, an auto-toxic substance is degraded, the occurrence of diseases is reduced, and the effect of continuous high and stable yield of the isatis indigotica is achieved.

Description

technical field [0001] The invention belongs to fertilizers, in particular to a method for making and using a special fertilizer for repeated cropping of Isatis indica. Background technique [0002] Woad ( Isatis indigotica ) is a biennial herb with important medicinal value. The root is used as Radix Isatidis, and the leaves are used as Folium Folium. It has the effects of clearing away heat, detoxifying, and cooling blood, and is good for preventing and treating infectious diseases. However, continuous cropping (heavy cropping) of Isatis indica for many years will cause problems such as reduced yield, aggravated pests and diseases, and decreased quality of medicinal materials. And GAP certification requires a stable production base, in order to solve such a contradiction, the invention provides a special fertilizer for repeated cropping of woad. Contents of the invention [0003] The invention aims to overcome the deficiencies of the prior art, and provides a method fo...
