当前,在大力发展人工种植肉苁蓉沙产业的过程中,人们期望通过对肉苁蓉Cistanche deserticola进行平茬切割来达到多年采收、提高品质和产量的目的。该试验对位于塔克拉玛干沙漠腹地的滴灌人工梭梭林内接种的肉苁蓉进行了不同发育期和不同留茬高度的平茬试验,结果表明:1肉苁蓉无论开花与否,还是肉质茎的粗细,被割断后均具有类似平茬的效果,而且萌发有3种形态类型。2割断后肉苁蓉的生长状况存在多种形式,既有正常萌发的,也有整体腐烂的、未萌发但保持鲜活的以及表面霉变腐烂下部萌发的现象。已经开花的相对未出土的肉苁蓉腐烂死亡率较高,40 cm留茬高度较20 cm和5 cm的死亡率高。3割断后存活的肉苁蓉留茬直径大部分会增加,但也有变化不明显的现象。4肉苁蓉被割断后伤口的霉变腐烂、在挖掘和割断过程中容易造成的挖断接种梭梭根系和接种点的脱落均会导致肉苁蓉的死亡,同时考虑平茬的实际增产效果和经济效益还需要进一步的研究评估,因此,在当前技术条件下,这一技术的运用需要谨慎。
At present, in the process of vigorously developing the cistanche desertification industry, people expect to achieve the goal of multi-year harvesting, quality improvement and yield by stubble cutting Cistanche deserticola. In this experiment, Cotinus cistanche was inoculated in the drip irrigation artificial Haloxylon ammodendron in the hinterland of Taklimakan Desert at different developmental stages and different stubble heights. The results showed that: 1 Cistanche tuberosum was irrigated or not, All have similar stubble effect, and germination has three kinds of morphological types. 2 cut Cistanche after the growth of a variety of forms, both normal germination, but also the overall decay, not germinated but remain fresh and the surface mildew under the germination of the phenomenon of rot. The relatively undeveloped desertification of Cistanche deserticola has a higher death rate, and the mortality of 40 cm stubble height is higher than that of 20 cm and 5 cm. 3 cut off the survival of the Cistanche stubble diameter most will increase, but there are also obvious changes in the phenomenon. 4 Cistanche is cut after the wound mildew decay, digging and cutting in the process of easy digging inoculated Haloxylon amnodendron root and the point of the fall will lead to the death of Cistanche, taking into account the actual production of stubble yield and economic benefits The need for further research evaluation, therefore, under the current technical conditions, the use of this technology needs to be cautious.
