晚粳品种采用秧苗带土移栽,密播与壮秧的矛盾十分突出,普遍反映密播后秧苗素质较差,成熟期延迟,影响产量提高。当前生产上以降低播种量的办法来培育壮秧,但带来了专用秧田面积大,插秧工效低等矛盾。为此,省农科院去年在嘉兴县东栅公社建新大队,进行以肥水管理促进和化学药剂抑制相结合,调节株型,增高叶片含氮量的试验,结果培育出了素质较好的秧苗,现将情况简介于下:
Late Japonica varieties with seedlings with soil transplanting, the contradiction between dense sowing and strong seedling is very prominent, generally reflects the poor quality of seedlings after sowing, delayed maturity, affecting the yield increase. Current production to reduce the amount of seeding ways to cultivate strong seedlings, but has brought a large area for special seedling, transplanting efficiency and other contradictions. To this end, the Provincial Academy of Agricultural Sciences last year in Jiaxing County, East Gate commune to build a new brigade, to fertilizer and water management and chemical suppression combined to adjust the plant type, increased leaf nitrogen content of the experiment, the results of cultivating better quality seedlings , The situation is briefly below:
