Morinda citrifolia sterilization preparation and preparation method thereof

Abstract

The invention provides a morinda citrifolia sterilization preparation and a preparation method thereof. The sterilization preparation is prepared from, by weight, 12-30 parts of adenophora trachelioides extracting solution, 10-25 parts of stellera chamaejasme extract, 8-15 parts of Eutrema yunnanense extract, 3-5 parts of semen lepidii oil and 0.3-1.5 parts of shikimic acid. All the raw materials are matched to achieve the antibacterial effect in a synergistic mode, and the sterilization preparation has high sterilization activity. The sterilization effects especially on pythium, anthracis, fusarium and Capnodiales fungus which all reach 90% or above, and also has high prevention and treatment effects on morinda citrifolia stem rot and anthracnose caused by the fungi, the prevention and treatment effects respectively reach 86.2% and 84.2% after 14 days, and the prevention and treatment effects on anthracnose reach 85.7% and 84.5% after 14 days.

Description

technical field [0001] The invention relates to the field of agricultural sterilization, in particular to a Morinda officinalis bactericidal preparation and a preparation method thereof. Background technique [0002] Seaside wood Morinda citrifolia (scientific name: Morinda citrifolia L.), also known as Morinda citrifolia L., is a shrub to small tree of Rubiaceae and Morinda citrifolia, up to 5 meters high; the stem is straight, and the branches are nearly quadrangular.

Inflorescence head every other node, opposite to leaves, many flowers, sessile; calyx tubes are more or less glued to each other, calyx eaves nearly truncated; corolla white, funnel-shaped, lobes ovate-lanceolate, bearing corolla Throat, filaments about 3 mm long, anthers introverted, style about as ...

AI Technical Summary

Problems solved by technology

[0003] Morinda officinalis is rich in nutrition and has high medicinal value. At present, my country’s Hainan and Yunnan have already started large-scale planting of Morinda officinalis. However, during the planting and cultivation process, the damage of diseases and insect pests threatens the growth of Morinda officinalis. It is found that anthracnose bacteria damage the leaves of Morinda officinalis, Fruits and tender stems, the lesion on the affected leaves is nearly round and light red at the initial stage, and the outer circle of the lesion is reddish brown; in the later stage, many dark brown cushion-shaped conidia discs grow on the lesion, and the center of the diseased tissue becomes dry and becomes Thin, papery; perforated at the end, and in severe cases, the lesions connect together to form larger lesions. After the fruit and tender stems are damaged, they often form slightly sunken, nearly round, brown lesions, and dark brown lesions grow later Cushion-like conidia discs; there is also stem rot, which is caused by Pythium, anthracnose, and Fusarium infection. The isolation frequency of pathogenic bacteria in different ecological zones is different, and the isolation frequency of pathogenic bacteria in the same ecological zone varies between years and regions. There are significant differences
