Method for planting bletilla striata

Abstract

The invention belongs to the technical field of bletilla striata planting, and particularly relates to a method for planting bletilla striata. The method comprises the steps of (1) land preparation and ridging, wherein sandy loam which has a deep soil layer, is fertile and loose, has a good drainage capacity, and is rich in organic matter is selected as cultivation soil, deep tillage is carried out, then a soil improvement agent is applied, fine raking, leveling and ridging are carried out, and the sandy loam is used for bletilla striata planting after being placed for 15 days; (2) seedling hardening, wherein bletilla striata acclimated seedlings are bought as seedlings; the seedlings are soaked in magnetized water, and then transplanted into a seedling hardening substrate for culture forone week; (3) planting; (4) field management, wherein intertillage weeding is carried out twice every year, shallow hoeing is carried out during each time of intertillage, and weeds around a cultivated land are removed; after intertillage weeding is carried out each time, an antibacterial fertilizer is used for topdressing once; watering and disease and insect pest prevention and control are carried out, and management is carried out according to a conventional planting mode. The provided method for planting the bletilla striata has the advantages that the occurrence rate of diseases and insect pests is low, the yield of the bletilla striata is high, and the quality is good.

Description

technical field [0001] The invention belongs to the technical field of bletilla striata planting, in particular to a method for planting bletilla striata. Background technique [0002] Bletilla striata, also known as Lianjicao, Gangen, Baigi, Ruolan, Zhulan, Zilan, etc., belongs to Baiji perennial herbaceous bulbous plants.

Problems solved by technology

[0003] In recent years, due to people's plundering harvest of wild Bletilla striata resources, the wild resources tend to decline or are on the verge of extinction. In the wild environment, the production of Bletilla striata is unstable due to the influence of natural conditions. To improve the yield and quality of Bletilla striata medicinal materials must Turn wild into domestic species, but artificial planting faces problems such as quality degradation, excessive chemical fertilizers, pesticide pollution, and seed disease. Moreover, the types and quantities of medicinal ingredients that are artificially planted often vary with regions and climates, which is unreasonable. The phenomenon of fertilization has also seriously affected the yield and effective components of medicinal materials, which has brought many difficulties to quality control.
