Method for constructing small and medium diameter class covering moso bamboo shoot-rhizoma corydalis imitation wild crop rotation system

Abstract

The invention belongs to the technical field of forestry, and relates to a method for constructing a small and medium diameter class covering moso bamboo shoot-rhizoma corydalis imitation wild crop rotation system. The method includes the following steps that a moso bamboo forest is selected; the moso bamboo forest is optimized; a rhizoma corydalis planting matrix is prepared; rhizoma corydalis is planted; weeding is conducted; topdressing is conducted; irrigation and drainage treatment is conducted well in time; prevention and treatment on diseases and insect damage is conducted well in time; rhizoma corydalis is harvested in the first year, or not harvested in the first year and continues to be cultivated till May in the second year to be harvested. The moso bamboo forest is managed, it is unnecessary to take young growth tending measures such as weeding, soil loosening, fertilizing and drought resisting in special projects, and labor is saved; rhizoma corydalis planting is achieved, moso bamboo coverage and rehabilitation in the mode of bamboo shoots in spring germinate in winter are promoted, the use ratio of the moso bamboo forest is increased, and incomes of farmers are increased. In addition, during rhizoma corydalis interplanting, soil used for moso bamboo forest covering is used, heavy subsoil application is not needed, and planting cost is reduced.

Description

Technical field [0001] The invention belongs to the technical field of forestry, and in particular relates to a method for establishing a wild bamboo shoot-corydalis imitating rotation system of medium and small diameter. Background technique [0002] Yanhusuo ( Corydalisyanhusuo W.T.WangexZ.Y.SuetC.Y.Wu), also known as: Yanhu, Xuan Husuo, Yuan Husuo, Yuan Hu, etc. It is a perennial herbaceous plant belonging to the family Papaveraceae and Corydalis. The tuber is spherical and the petals are purple-red; the capsule is cylindrical and narrow at both ends. Flower in summer. Tuber is a well-known and commonly used traditional Chinese medicine, containing more than 20 kinds of alkaloids, which are used for promoting qi and relieving pain, promoting blood circulation and removing blood stasis, and traumatic injuries.

Problems solved by technology

[0003] The traditional planting method of Corydalis Corydalis is the field cultivation method. A lot of fertilizers are wasted during the planting process, resulting in soil compaction; most of Corydalis Corydalis is harvested within one year of planting, and the active ingredients are low; after the field is cultivated, the above-ground part needs to be used in large quantities to prevent it from growing. To prevent downy mildew, sclerotinia and rust from March to April, pesticide residues are serious, and manual labor is large; field cultivation cannot be planted continuously, and other crops need to be rotated every year
