摘要
测定不同施磷水平处理条件下燕麦幼苗形态指标及相关生理指标,探讨施磷量对燕麦苗期生长状况的影响。结果表明:燕麦苗期株高、叶面积随施磷量的增加呈先增加后降低趋势,均在施磷量为306 kg·hm^(-2)条件下达到最大值,分别为16.93 cm、451.27 mm^(2);燕麦苗期植株体内可溶性糖、可溶性淀粉、可溶性蛋白随施磷量的增加呈先增加后降低趋势,均在施磷量为306 kg·hm^(-2)条件下达到最大值,分别为4.35 mg·g^(-1)、6.68 mg·g^(-1)、4.10 mg·g^(-1)。综合来看,燕麦最佳磷肥施用量为306 kg·hm^(-2)。
By measuring the morphological and physiological indexes of oat seedlings under different phosphorus application conditions,the effects of phosphorus application on the growth status of oat seedlings were discussed.The results showed that the plant height and leaf area of the oat seedling stage showed a trend of increasing first and then decreasing with the increase of phosphorus application,and the maximum value was reached under the condition of phosphorus application of 306 kg·hm^(-2),which were 16.93 cm and 451.27 mm^(2),respectively.Soluble sugars,soluble starches and soluble proteins in the plant of oats at seedling stage showed a trend of increasing first and then decreasing with the increase of phosphorus application,and they all reached the maximum value under the condition of phosphorus application of 306 kg·hm^(-2),which were 4.35 mg·g^(-1),6.68 mg·g^(-1),and 4.10 mg·g^(-1),respectively,and the best phosphate fertilizer application amount of oats was 306 kg·hm^(-2).
