5.After multi purpose soil disinfectant fumigated the vegetable seedling bed,disease rate,quantity of living soil insects and weeds in seedling bed were reduced significantly,moreover,growth of the seedling was promoted,sound seedling index was raised.
多效土壤消毒剂对蔬菜育苗苗床进行熏蒸消毒 ,可以有效降低苗期病害发生率、地下害虫虫口密度和杂草数量 ,并显著促进苗期生长发育 ,提高其壮苗指数
6.Accurately locating the root collar of seedling is important for the measurement of seedling morphological characteristics in the computer vision system of seedling grading. A RC ASL ( Root Collar Automatic Searching and Locating ) method based on fuzzy neural network (FNN) has been studied to resolve the key problem in the field of conifer seedling feature extraction. In the computer vision system, the features of the object may be extracted based on the hue variation of the image.
