Bio-organic fertilizer for planting lotus root

Abstract

The invention provides a bio-organic fertilizer for planting a lotus root. The lotus root is a crop with relatively high economic value and nutritive value, but lotus root rot is frequently caused due to continuous cropping. The lotus root rot mainly occurs in the underground stem and root of the lotus root, causes the problem that leaves of the over-ground part turn yellow, or brown and rotten, or even causes withering of the over-ground part; the initial symptom of the underground part is not significant, and a vascular bundle close to the center turns brown after being opened, and gradually expands and extends to the newborn underground steam, or even the underground stem is rotted and blackened; the symptoms of the leaves of the over-ground part also appear; the leaves become light, and are dried up and curled, or even the leaves in the entire field are withered and yellow, and are in a burned state; hyphae and pink sticky substances appear from the underground stem of the infected plant; a part of underground stem displays water-soaking scabs; finally, a lotus whip, the infected stem and the infected root part display purple-brown scabs; the interior of the lotus whip turns brown; the infected stem shrinks in the longitudinal direction; and the lotus root dies. The firstly infected part of the lotus root rot is in an aquatic environment, and 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 as a raw material. Background technique [0002] Lotus root rot disease mainly occurs in the underground stems and roots of lotus root, causing yellowing, browning and rot of the leaves above the ground, and even the withering of the aboveground parts. The symptoms of the underground stems are not obvious at the initial stage, and the vascular bundles near the center can be seen to be browned by dissection, and gradually expand and extend to the new underground stems, and even cause the rot and blackening of the underground stems. The leaves on the ground also appear sick, the leaves become pale, dry, curled, and even the whole field is yellow and burnt. Mycelium and pink sticky substances appeared on the underground stems of diseased plants, and some of them showed water-soaked lesions. Finally, the lotus...

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.
