摘要
通过不同施磷肥处理对苜蓿种子产量及种子产量构成因子的研究表明,当施用磷肥为135 kg/hm2,可显著提高苜蓿种子产量,达564.8 kg/hm2,比对照增加75%。磷在苜蓿生殖生长阶段有向生殖器官转移的趋势,各处理植株器官中含量依次为:种子>荚>叶>茎>根。磷还可明显增多单株花序数,提高干物质重量和单株粒重。
Studies on the effects of treatment with diferent phosphorus on alfalfa seed yield and on the component factors of seed yield were investigated. The experiment results indicated that when the amount of phosphorus of 135 kg/hm^2 was applied, alfalfa seed yield could greatly be increased by 75 %, which reached the amount of 564.8 kg/hm^2. Phosphorus had the trend in transfering toward the fructification in reproduction growth stage of alfalfa, the content of phosphorus in plant organ in order of decreasing importance was reproductive seed, pod, leaf, stem, and root with different treatment. Phosphorus eould improve No. inflo/plant , dry matter weight and seed weight/plant.
