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%。
Taking the rice variety “Lingliangyou 916” as material, the local traditional soaking method (strong chlorine disinfection soaking) was used as control to study the effects of Jiahebao seeds endogenous nutrient solution soaking on the quality of machine-inserted seedlings, the growth and yield of transplanted early rice influences. The results showed that compared with the control, the seedling emergence rate of seedling increased by 5.1% and the number of white roots increased by 0.7 / plant, the plant height and root length increased by 0.5 cm and 0.7 cm, respectively. After transplanting, the seedling rejuvenation period was shortened by 5 days than the control, and the whole growth period was shortened by 2 days. The tiller number was significantly higher than that of the control, and the spikeage rate of stem tiller was 0.6% higher than that of the control. There was no significant difference between the two. Jia Hebao nutrient solution soaking treatment increased the effective panicle number of rice than the control 0.7 million ear / 667m2, grain number per panicle increased 2.7 grains / ear, seed setting rate increased 0.7 percentage; rice yield 2.56% more than the control.
