甘薯耐瘠薄,耐干旱,有“先锋”作物之称。近几年由于受自然灾害的影响以及农艺农技措施的不协调,严重影响了甘薯安全生产,甘薯种植效益难以得到保证,重茬障碍以及病虫危害,甘薯产量一直徘徊不前。针对甘薯生产实际,以往年生产中遇到的自然以及人为的因素,对甘薯安全生产造成的不利因素为依据,科学预测2015年影响甘薯安全生产的相关因子,是确保甘薯高产优质的重要举措之一。
Sweet potato is resistant to infertility, drought-resistant, with “pioneer ” said. In recent years due to the impact of natural disasters and agronomic agronomic measures are not coordinated, seriously affecting the safety of sweet potato production, sweet potato planting is difficult to be guaranteed, stubble obstacles and pests and diseases, sweet potato production has been stagnant. In view of the actual production of sweet potato, the natural and man-made factors encountered in previous years’ production, it is based on the unfavorable factors caused by sweet potato’s production safety. It is an important measure to ensure the high yield and quality of sweet potato by scientifically predicting the related factors that affect the safe production of sweet potato in 2015 one.
