Biological organic fertilizer for planting lotus roots

Abstract

The invention provides a biological organic fertilizer for planting lotus roots. The lotus roots are crops with a high economic and nutrient value, but the rot disease of the lotus roots is often caused due to continuous cropping. The rot disease of the lotus roots is mainly generated at the subterranean stems and the roots of the lotus roots, so that leaves of the overground parts of the lotus roots become yellow, brown and decomposed, and even the overground parts are sapless. The initial symptom of the underground stems is not obvious, when the underground stems are split, the vascular bundles near the center of the underground stems become brown, newborn underground stems gradually become brown, and even the underground stems are decomposed and become black. Then, the the leaves of the overground parts have symptoms of the disease, the color of the leaves become light, the leaves are withered and curly, and even the leaves of the lotus roots in the whole field are withered and yellow and same like being burnt by fire. Mycelium and pink glutinous substances appear on the underground stems of diseased plants, and partial underground stems of the diseased plants present water-soaking scabs. Finally, the diseased parts of lotus whips, diseased stems and roots all present purple brown disease scabs, the inner parts of the lotus whips become brown, the diseased stems are longitudinally creased, and the lotus roots are necrotized. The first part, infected by rot disease, of the lotus roots is in aquatic environment, so that the disease is not easy to find and is difficult to prevent and treat.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a compound fertilizer made from molasses alcohol waste mash. Background technique [0002] The lotus root rot disease mainly occurs in the underground stems and roots of the lotus root, causing the aboveground leaves to turn yellow, brown and rot, and even cause the aboveground parts to wither. The initial symptoms of the rhizomes are not obvious, but the vascular bundle near the center can be seen to turn brown when cut open, and gradually expand and extend to the new rhizomes, even causing the rhizomes to rot and turn black. The leaves above the ground will also appear sick, and the leaf color will become pale, dry, and curled, and even the whole field will be yellow and burnt. Hyphae and pink viscous substances appeared on the underground stems of the diseased plants, and some of them showed water-soaked lesions. Finally, the lotus whip, the diseased stem and th...

Problems solved by technology

However, in the case of not changing the variety of lotus root and continuous cropping, there is no technical plan to ensure that the lotus root rot does not occur. After the fungicide has been used to kill the spoilage bacteria in the farmland, after the toxicity of the fungicide subsides, the chance of the spoilage bacteria reappearing is very high.

Moreover, the use of fungicides for years will cause pathogenic bacteria to develop drug resistance and drug resistance, resulting in a decline in the bactericidal effect year by year.
