根据天麻——蜜环菌——寄主植物三者双重寄生现象和它们之间生态关系的研究,欲想发展天麻生产,就必须创造一个既适宜天麻,又适宜蜜环菌生长的良好环境。一、选择适宜的场地种植天麻以半沙半土的土壤为好,粘土和透气性差的强碱性的土壤不适宜。一般应选择含腐殖质丰富的沙壤土,团粒结构良好,透气渗水性强,土壤湿度60 9,6左右为宜,酸碱度(pH)5.5-6的场地为最好。为了保持一定的荫蔽条件,最好在林间栽培,平地则可搭凉棚。山区宜选向阳坡,丘陵区宜选半
According to the double parasitism of Gastrodia elata - Armillaria mellea - host plant and the ecological relationship between them, if we want to develop the production of Gastrodia elata Blume, we must create a good environment that is suitable both for Gastrodia elatior and Alternaria solanacearum. First, select the appropriate site to grow Tianma half-soil half soil as well, clay and poor permeability of alkaline soil is not suitable. In general, sandy loam with abundant humus should be selected. The pellet structure is good, the permeability and water permeability is good, the soil moisture is about 60.9 and about 6, and the pH value is 5.5-6. In order to maintain a certain shade conditions, it is best to cultivate in the forest, the flat can take shelter. Mountain should choose sunny slope, hilly area should choose half
