摘要:
为促进黑龙江省水稻生产，设置4种播种量、3种育苗基质和2种育苗方式的对比试验，研究了不同播种量、不同育苗基质以及不同育苗方式对秧苗素质及产量的影响。结果表明：每盘干籽播种量100 g、普通育苗土以及钵体育苗处理的秧苗素质较好，表现为叶龄较大、株高较矮、带蘖数量较多、茎基较宽、根数较多和根长较长，地上干重和根干重较大；同时实测产量最高。在机械插秧育壮苗关键技术环节中，干籽播种量应在100~125 g；育苗基质应以普通育苗土为主；育苗方式应以钵育为主，普通毯盘育苗为辅，尤其优质稻米栽培要用钵育苗，秧苗素质好，苗壮早生快发，能多争取1个叶片的积温，为后期灌浆成熟提供足够温度。
Abstract:
In order to promote rice production in Heilongjiang Province,four types of seeding rates,three types of seedling substrates,and two methods of seedling comparison tests were set up to study the seedling quality and yield with different seeding rate,different seeding substrates,and different seedling methods.The results showed that the seedlings quality of 100 g dry seed of per plate,ordinary seedling soil,and bowl seedlings were better,which were characterized by older leaf age,shorter plant height,more tillers,wider stem base,more root number and the longer root length,the ground dry weight and root dry weight were larger; meanwhile,the measured yield was the highest.In the key technical link of mechanical seedling breeding,the seeding amount of dry seeds should be between 100-125 g; the seedling substrate should be mainly based on ordinary seedling soil; the seedling method should be based on bowl cultivation,supplemented by ordinary blanket tray seedlings,especially high-quality rice cultivation required bowl seedling cultivation,the seedlings quality was better,and the seedlings growed early and quickly,could strive for an accumulated temperature of one leaf,and provided sufficient temperature for the later stage of filling.
