Ligusticum wallichii cultivation method capable of reducing plant pest and disease damage and increasing survival rate and yield

Abstract

The invention discloses a ligusticum wallichii cultivation method capable of reducing plant pest and disease damage and increasing survival rate and yield. The method comprises the following steps: sequentially performing rice seedling planting and rice harvesting, regular soil preparation, poria seed planting, field management and ligusticum wallichii harvesting within a planting period; specifically, in the regular soil preparation, performing immersed soaking treatment on farmland with rice harvested, soaking and draining accumulated water out of the field, ploughing, then finely raking, flattening surface soil, ditching and excavating shallow trenches; in the poria seed planting step, performing cuttage on poria seeds at the bottom of the shallow trenches, and immediately covering with straws along the shallow trenches after cuttage; and in the field management step, supplementing seedlings, weeding, draining water, applying fertilizer and performing pest and disease prevention. According to the ligusticum wallichii cultivation method, the block stem rotten sickness and grub damage of the ligusticum wallichii can be effectively reduced, the physiological seedling death and withering are effectively prevented, the purpose of returning straws to the field can be achieved, the root development of the ligusticum wallichii can be promoted, the field weeds can be reduced, and the yield of the ligusticum wallichi can be effectively increased.

Description

technical field [0001] The invention belongs to the technical field of planting medicinal materials, and more specifically relates to a cultivation method of Rhizoma Chuanxiong that can reduce the damage of diseases and insect pests and improve the survival rate and yield. Background technique [0002] Ligusticum chuanxiong is the dry rhizome of Rhizoma Chuanxiong of Umbelliferae, with compound umbels and pinnate compound leaves, and is a perennial herb. Chuanxiong was first recorded in "Shen Nong's Materia Medica", and it is one of the authentic medicinal materials in Sichuan. Harvest in summer when the nodules on the stems are protruding and slightly purple, remove the sediment, dry them in the sun, and then remove the fibrous roots; it tastes pungent, slightly bitter, and warm in nature, and is mainly returned to the liver, gallbladder, and pericardium Jing, has the effects of promoting blood circulation, dispelling wind and relieving pain, and is the first choice for tr...

Problems solved by technology

[0003] However, the traditional cultivation method of Chuanxiong can easily lead to problems such as tuber rot disease and grub hazards; and, after the cuttings of Rhizoma chuanxiong, physiological dead seedlings and withered seedlings are often caused by water loss, direct sunlight, and rain, which not only leads to Ligusticum chuanxiong cultivars have a high rate of lack of nests and large fluctuations in yield, and the income of growers and the relationship between supply and demand of medicinal materials are not guaranteed
