Soilless three-dimensional planting method of Gastrodia elata

Abstract

The invention provides a soilless three-dimensional planting method for gastrodia elata. Gravels with the particle size of 10-20 meshes substitute for conventional selected loam or sand loam which is moist, breathable, good in water permeability, loose and rich in humus content, and a precedent of planting the gastrodia elata with the gravels is created; by three-dimensional planting, land resources are saved. The method is characterized by including: using plastic baskets for realizing three-dimensional planting, using tree leaves, smashed crop offal and the gravels for substituting for the loam or sand loam moist, breathable, good in water permeability, loose and rich in humus content for planting the gastrodia elata; for post-plantation management, keeping water content in the plastic baskets to be 40-50% and keeping the temperature at 15-28 DEG C without draining and spraying pesticides for pest control. The plastic baskets are stacked in multiple layers to realize three-dimensional planting and can be placed outdoors as well as indoors without occupying land resources, and yield in unit area is increased greatly; by the method, one more path is added for expanding the gastrodia elata in China.

Description

technical field

[0001] The invention relates to the planting field of Gastrodia elata, in particular to a soilless three-dimensional planting method of Gastrodia elata. Background technique

[0002] China is a big producer of Gastrodia elata. According to the production environment of Gastrodia elata, there are home-grown and wild Gastrodia elata; according to the variation of flower color, flower stem color, tuber shape, and tuber water content, Gastrodia elata can also be divided into red gastrodia, red gastrodia, There are 4 types of green gastrodia, black gastrodia and yellow gastrodia.

[0003] Gastrodia elata growth habit: It is suitable for growing in loose and moist sandy loam, the optimum temperature for growth is 15-28 degrees Celsius, and the growth will stop when the local temperature is lower than 8 degrees and higher than 30 degrees. Gastrodia elata must rely on Armillaria armillaria to provide nutrients for growth and development.
