摘要: 河北对苜蓿充分供应氮、钾、磷等其他营养的情况下,就不同硫营养水平对紫花苜蓿产量、生物学性状及再生速度的影响进行研究。结果表明:S2处理在现蕾期、初花期和盛花期的株高、茎粗、产量和增产效益最佳;S3处理的再生速度最大;茎叶比随着硫营养水平的不断增长逐渐下降。通过对各个性状的分析,得出在本试验条件下S2为硫肥最佳用量。

关键词: 紫花苜蓿, 硫营养, 生物学性状, 再生速度

Abstract: The experiment is carried under greenhouse conditions of Resource and Environment Institute of Hebei Academy of Agriculture and Forestry Sciences. Providing required nutrients of N, P, K and other essential nutrients thisstudy aims to determine the effects of different levels of sulfur on the herbage yield output, biological characterist ics andspeed of regeneration of alfalfa. Research results show that S2 has best effects on plant height, leaf diameter, herbage yieldoutput and it is economically efficient in increasing production from first stubble branching to first stubble floweringstages,while S3 has best effects on the regeneration speed.The plant stem leaf ratio decreases as sulfur nutrit ion level increases. Analysis of each biological character shows that S2 is best sulfur treatment for alfalfa in this study.

Key words: Alfalfa, Sulfur nutrition, Biology character, Regeneration speed
