科学研究表明,红薯翻秧费工减产。一般667平方米减收鲜薯150—250公斤,多次翻秧者.减产达600—1000公斤。 翻秧减产的主要原因:一是翻秧后,茎叶互相缠压,打乱了茎叶自然合理分布,不利光合作用。二是造成茎叶损伤脱落,翻秧时,部分薯秧被折断,特别是叶片损伤最严重,一般叶片损伤30％以上。三是翻秧后,地表裸露,加速土壤水分蒸发,降低抗旱能力。 Scientific research shows that the sweet potato transplanting costs reduction. General 667 square meters to reduce the amount of fresh 150-250 kilograms of potatoes, many transplanter who cut 600-1000 kilograms. Transplanting the main reasons for reducing production: First, after transplanting seedlings, stems and leaves intertwined with each other, disrupted the natural and rational distribution of stems and leaves, adverse photosynthesis. The second is caused by stems and leaves injury fall off, transplanting seedlings, some potato seedlings are broken, especially the most serious leaf damage, leaf damage in general more than 30%. Third, after transplanting, the surface bare, speed up soil moisture evaporation, reduce drought capacity.
