辣椒漂盘苗机械化移栽适应性研究OA

n order to explore the adaptability of capsicum floating seedlings to mechanized transplanting,the capsicum floating seedlings at the appropriate planting period in a capsicum base in Guizhou and 2ZB-2 dry land hanging cup duckbill clip transplanter were tested.The experimental studies on the measurement of capsicum seedling morphological characteristic parameters,seedling media loss and field mechanized planting were completed.The results show that the media of the floating seedlings was full,and it is suitable for the common duckbill clip planter.When the moisture con-tent of media of floating seedlings is 56.4～63.5%,it is beneficial to maintain the media of mechanical transplanting.The qualified rate of planting depth,the rate of missed planting and the rate of injured seedlings were 76.7%,2.4%and 3.2%respectively,which meet the index requirements;The acceptable rate of straightness is 88.7%,which is lower than the lower limit of 93%.In general,the adaptability of capsicum floating plate seedling and transplanter is good,which can basically meet the requirements of mechanized capsicum planting in Guizhou.
