增施磷肥,促使甜菜苗全苗壮,加速封垄,百株重比对照田增加14.9%,根叶比适宜,封垄提前一周左右。磷肥促使甜菜有明显地抗御病害,黑脚病罹病率为4%,而对照田为22%,黄化毒病和褐斑病发生轻微,而对照田的发病率分别为15%、10%.磷肥促使甜菜具有一定的抗旱作用,使甜菜生长能挺拔直立,叶片舒展,而对照田叶片下垂,有闭晌现象。磷肥能提高甜菜产量和含糖,比对照田增产19.9%,含糖比对照提高3.86度.增施磷肥能促使甜菜早熟,减少有害非糖成份,降低含水,提高视纯度。
Phosphorus fertilizer was added to promote the seedling growth of sugar beet seedlings and accelerate the closure of the ridge. The weight of one hundred plants increased by 14.9% compared with that of the control field, and the ratio of root and leaf was suitable, and the sealing ridge was about a week earlier. Phosphorus fertilizers promote sugar beet obviously resist disease, blackfoot disease prevalence rate of 4%, while the control field was 22%, yellow and brown spot disease occurred slightly, while the control field incidence rates were 15%, 10%. Phosphate fertilizer to promote sugar beet has a certain role in drought resistance, beet growth can be upright and upright, leaves stretch, while the control leaves sagging, there is no phenomenon. Phosphorus fertilizer can improve sugar beet yield and sugar content, yield 19.9% more than the control field, sugar increased 3.86 degrees compared with the control.Application of phosphate fertilizer can promote sugar beet precocious, reduce harmful non-sugar components, reduce water content, improve visual purity.
