不同育秧剂对陕南稻麦油两熟区机插秧秧苗素质与栽插质量的影响

以常规中籼稻黄华占为材料,采用温室大棚旱育秧方式,研究不同育秧剂对陕南稻麦油两熟区机插秧秧苗素质与栽插质量的影响。结果表明,温室大棚旱育秧方式下,秧苗适栽期为播种后31~38 d,大田栽插穴苗数为5苗/穴;秧苗综合品质比较,表现为育秧基质旱育保姆育秧伴侣对照CK;大田栽插比较,育秧基质效果最佳,呈现返青快,单株分蘖高的特点;经济性状比较,表现出育秧基质旱育保姆育秧伴侣的总体效果。合理筛选育秧剂和栽插条件,能提高秧苗素质,改善群体发育动态,实现增穗增粒,提高产量,有效促进机械化稻作技术在本地区的推广。

Effect of Different Seedling Strengthen Agent on Seeding Growth and Growth Quality of Machine-transplanted Seedlings in Wheat-rice or Wheat-rape Double Cropping Area in South Region of Shanxi Province

This paper analysis the effect of different seedling strengthen agent on seeding frowth and frowth quality of machine-transplanted seedlings in wheat-rice or wheat-rape double cropping area in south region of Shanxi province with rice Huanghuazhan as material and dry seedbed as method. The results showed that suitable transplanting period was 31-38 days after sowing in dry seedbed and 5 seedlings a hole. The seeding quality in order to seedling raising materials > drought-foster nurse > seeding raising companion > control CK; Coming to the field planting, seedling raising materials performs better, it turns green quickly. The economic character in order to seedling raising materials > drought-foster nurse >seeding raising companion. Reasonable machine-transplanted condition and better seedling strengthen agent can improve the growth and production of machine -transplanted seedlings. It can also promote the generalization of machine -transplanted seedlings in south region of Shanxi province.
