Cultivation method for preventing plant diseases and insect pests from biting and eating rhizoma polygonati seedlings

Abstract

The invention discloses a cultivation method for preventing plant diseases and insect pests from biting and eating rhizoma polygonati seedlings, and particularly relates to a Chinese herbal medicine cultivation method, which comprises the following steps: S01, after the cultivated land is plowed, the grass is laid on the surface of the soil, and after the grass fully is burnt out, the cultivated land is levelled; S02, the leveled cultivated land is covered with composite soil evenly; S03, the cultivated land which is coved with composite soil is ditched and divided into blocks, and channels are formed into the periphery of the said blocks; S04, planting pits with a depth of 6-8cm, a row spacing of 35-50cm and a plant spacing of 20-30cm are dug on the blocks, and then the sterilized rhizomapolygonati tuberous root is buried into the planting pits; S05, the dried pine needles with a thickness of 3-5 cm is spreaded on the surface of the cultivated land on which the rhizoma polygonati isplanted. The method has the advantages that the rhizoma polygonati seedlings can be prevented from being bitten and eaten by injurious insects without applying pesticide during the cultivation process, so that the planted rhizoma polygonati is more environment-friendly and non-toxic without any side effects on eaters.
