| 摘 要： | 以水稻品种陵两优916为材料,以当地传统浸种方法 （强氯精消毒浸种）为对照,研究了稼禾宝种子内质营养液浸种对机插秧苗素质、移栽早稻生长发育和产量的影响。结果表明,与对照相比,营养液浸种处理秧苗成苗率增加5.1个百分点,白根数增加0.7条/株,株高和根长分别增加0.5 cm和0.7 cm。移栽后秧苗的缓苗期比对照缩短5 d,全生育期缩短2 d。分蘖数均明显高于对照,茎蘖成穗率比对照增加0.6个百分点,两者间无明显差异。稼禾宝营养液浸种处理水稻有效穗数比对照增加0.7万穗/667m2,穗粒数增加2.7粒/穗,结实率增加0.7个百分比;水稻产量比对照增产2.56%。

| Abstract: | The effects of Jiahebao nutrition liquid soaking seed（ Jiahebao treatment） on the seedling quality, growth and grain yield of machine-transplanted early rice by using rice variety Lingliangyou 916 as a material were studied. The results showed that the seedling ratio of the Jiahebao treatment increased 5.1 percent points compared with the local traditional soaking method（CK）; the number of white root of early rice seedling increased by 0.7, the plant height and length of root increased by 0.5 cm and 0.7 cm, respectively, compared with the CK;the rejuvenation period and whole growth period of the Jiahebao treatment were 5 d and 2 d shorter than that of the CK, respectively; the number tillers of the Jiahebao treatment were higher than that of the CK, and the spike rate increased by 0.6 percent points; and the number effective tillers were increased by 10.5 ×104/hm2, grain number per spike was increased by 2.7, seed setting rate was increased by 0.7percentage, compared with the CK. Therefore, the grain yield of the Jiahebao treatment increased by 2.56 percent points, compared to the CK. |
