农田土壤与腐植土比较,土壤板结容重大,播种深度不适是严重影响农田人参出苗率的重要因素,随着农田栽参的日益发展,探讨农田适宜的人参播种深度尤为必要。试验材料方法试验地选休闲三年的农田地,种子采用处理好的裂口种子(没经挑选)。试验采用裂区设计,主因素为播深,分1厘米、2厘米、3厘米、4厘米、5厘米、7厘米、9厘米七个处理,副因素为扣地膜,分扣膜和不扣膜二个处理。随机排列,三次重复,小区面积0.5平方米。 Compared with the humus soil, the soil bulk density is very big, and the sowing depth is an important factor that seriously affects the seedling emergence rate of ginseng. With the development of farmland ginseng, it is necessary to explore the suitable ginseng sowing depth. TEST MATERIALS Methods Three-year-old farmland was selected and the seeds used were treated with split seeds (unselected). Experimental design using split zone, the main factor for sowing, sub-1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 7 cm, 9 cm seven treatment, the sub-factor deduction film, Two processing. Random arrangement, three repetitions, the plot area of ​​0.5 square meters.
