摘要: 通过对留种苜蓿植株生长发育及产量的研究,表明灌水对留种苜蓿的生长发育和种子产量有着密切的关系;灌水还可能造成植株的倒伏,使苜蓿种子的产量和质量受到影响.其原因是倒伏影响了昆虫的授粉,同时新生枝条迅速生长削弱了生殖生长的养分供应。对留种苜蓿在蕾期和花期避免灌水可减轻倒伏程度,在荚期灌一水即可。

Abstract: Study on the growth develop and the quality of seed of alfalfa, the result shows that water can effect the growth and develop of alfalfa, also effect on the produce and quality of the seed. There were obvious relationships between the seed output and growth develop. So we know that plant Alfalfa for seed water once is enough.
