Disease and pest control method for polygonatum canaliculatum

Abstract

The invention discloses a disease and pest control method for polygonatum canaliculatum. The method comprises the steps of garden cleaning and land preparation, selection of a cultivation way, seed stem selection, disease control and pest control. The method is throughout the whole planting period of the polygonatum canaliculatum, and the effect is good; before planting, quick lime is spread, on the one hand, land can be sterilized, and diseases and pests in the land can be eliminated; on the other hand, the quick lime can serve as a fertilizer to provide nutrients for planting the polygonatumcanaliculatum. A deep ploughing planting way is adopted, land hardening can be changed, and absorption and growth of roots of the polygonatum canaliculatum can be enhanced; death of the pests can bepromoted, the growth and propagation of germs are not facilitated; in the cooperation of the planting way of interplanting crops or a protection band, a barrier function can be achieved, and fly mating and oviposition of the pests are prevented; different diseases and pests of the polygonatum canaliculatum are controlled and processed by using different ways; for control over the pests of the polygonatum canaliculatum, rhizomes and agents are mixed to be planted in the planting process, and by cooperating the way that pits are dug in the land and the agents are spread on the land in necessity,the pests of the polygonatum canaliculatum rhizomes can be completely eradicated and killed.

Description

Problems solved by technology

[0003] In the growth process of sealwort, common diseases and insect pests include black rot, leaf spot, anthracnose, grub and cutworm, which need to be controlled in time; if not timely control will result in low quality and low yield of sealwort, resulting in greater losses Most of the existing control methods adopt pesticide control, which is relatively single, not only easy to damage the ecology, but also too much pesticide will cause the slow growth of sealwort
