白术(Atractylodes macrocephala)在培育术苗期,常常出现程度不同的缺苗。产生这种情况的主要原因有: 1.播种不匀白术播种方法现多采用条播和撒播,种子未撒匀,影响出苗。2.种子出芽率低种子颗粒饱满,出芽率高;瘪种则出芽率低。浸种时,瘪种多浮于水上面。瘪种不剔除,可影响出苗。3.未注意土壤保湿播种后,一定的土壤湿度有利于出苗。如土壤干燥,则种子回芽,影响出苗。4.其它浸种的时间过长或过短,苗期的病虫害等。为了提高土地的利用率,笔者将白术苗进行移栽或合并田块,方法简单,对白术的生长无影响。移栽的时间以五月下旬～六月上旬、
Atractylodes macrocephala seedlings at the nursery stage, often with varying degrees of lack of seedlings. The main reasons for this situation are: 1. Sowing uneven Atractylodes sowing methods are now more use of broadcast and sowing, the seeds are not spread, affecting emergence. 2. Seed germination rate is low seed particles full, budding rate is high; defoliate seedling rate is low. Seed soaking, defoliated species floating in the water above. Deflated species are not removed, can affect the emergence. 3. Did not pay attention to soil moisture sowing, a certain degree of soil moisture is conducive to emergence. If the soil is dry, the seeds will germinate and affect emergence. 4. Other soaking time too long or too short, seedling pests and diseases. In order to improve the utilization of the land, the author transplants or combines the transplanted Atractylodes field, the method is simple, has no effect on the growth of Atractylodes. Transplanting time in late May to early June,
