Scientific planting method of rhizoma corydalis

Abstract

The invention discloses a scientific planting method of rhizoma corydalis, and belongs to the field of rhizoma corydalis planting. The method comprises the following steps: S1, land selection and preparation, wherein a paddy field, an autumn corn field, a melon field and the like which are flat in terrain, convenient to drain and irrigate and loose in soil are selected for planting; S2, timely planting, wherein the sowing period is before or after the first ten-day period of October, the yield and quality of the rhizoma corydalis can be influenced if sowing is too late, and due to the fact that the growth period of the upper portion of the rhizoma corydalis is only 80 days or above, sowing can be early but cannot be late; S3, management enhancement, wherein at the early growth stage of tubers in the middle ten-day period and the last ten-day period of October, surface soil shallow loosening and weeding are conducted once; S4, disease control, wherein paddy-upland rotation is needed, ditching and drainage are conducted, the field humidity is reduced, at the disease stage, 1000-fold liquid of 50% thiophanate wettable powder is sprayed once every 10 days, and an overwinter fertilizeris heavily applied for topdressing; and S5, timely harvesting, wherein harvesting is conducted from May 10 to May 15. The planting method is scientific, the survival rate of the rhizoma corydalis is high, the yield is high, and the quality is good.

Description

technical field [0001] The present invention relates to the field of planting Rhizoma chinensis, more specifically, to a scientific planting method of Rhizoma radix. Background technique [0002] Yuanhu is a plant of the poppy family, alias: Xuanhu and Yanhusuo. It has the functions of promoting blood circulation and dissipating blood stasis, regulating qi and relieving pain. , likes warm climate and sunny and humid environment, avoids drought, requires uniform rainfall, especially in the period of tuber expansion in early and mid-April, needs "three sunny and three rainy" weather conditions, favorable for tuber growth and development, Corydalis shallow roots Crops require loose and fertile soil, and plots with heavy soil and low-lying water are not suitable for planting. [0003] In the past few years, the planting of Yuanhu has not been able to achieve high yield, and even ended in failure. This is because the original planting method is still used, there are still shortc...
