在萝卜苗期喷施多效唑,可抑制地上部营养生长过旺,合理调节植株体内光合产物的分配和运转,既能保证萝卜有足够的营养面积进行旺盛的光合作用,中后期还可保持功能叶不过早衰败,延长光合作用时间,有利地下肉质根的膨大,且能预防萝卜空心,增产增效显著。据调查,喷施田萝卜空心株率为0.6%,比不喷田下降17.7个
In the radish seedling spraying paclobutrazol, can inhibit the over shoot vegetative growth, reasonable regulation of plant photosynthate distribution and operation, both to ensure that radish has enough nutrient area for exuberant photosynthesis, but also to maintain functional leaves in the late However, early decay, prolonged photosynthesis time, the fleshy roots beneficial to the expansion, and can prevent radish hollow, increase yield and efficiency significantly. According to the survey, the rate of applying hollow carrot radish is 0.6%, 17.7 less than that of no spraying field
