目前不少厂家出售的棉籽壳中,一般含棉籽在10～30%,为弄清棉籽对发菌及产量的影响,我们做了以下试验。(一)试验设计A.棉壳中含棉籽15%;B.棉壳中含棉籽30%;C.纯棉籽;D.纯棉壳(对照)。(二)试验方法采用瓶栽法,装瓶后于1.2～1.5kg/cm~2下灭菌1小时。2月28日接种,品种为平07,接种后在20±1℃恒温箱中培养,1个月后移至室温下发菌,按常规管理。(三)试验结果发菌速度,4个处理均较一致。现原基期,以处理D(对照)最早(3月28～28日),其次是处理A(3月26日～4月1日)和处理B(3月31日～4 At present, many manufacturers sell cotton seed hulls, cottonseed generally contains 10 to 30%, in order to clarify the effect of cottonseed on the hair bacteria and yield, we have done the following test. (A) Experimental Design A. Cottonseed contains 15% cottonseed; B. Cottonseed contains 30% cottonseed; C. Pure cottonseed; D. Pure cottonseed (control). (B) test method Bottle cultivation method, after bottling at 1.2 ~ 1.5kg / cm ~ 2 sterilization 1 hour. February 28 vaccination, breed flat 07, after inoculation in 20 ± 1 ℃ incubator, one month later moved to room temperature germs, according to conventional management. (C) the test results Germination speed, four treatments are more consistent. The original base period to deal with D (control) earliest (March 28 ~ 28), followed by the treatment of A (March 26 ~ April 1) and treatment B (March 31 ~ 4
