复合肥浓度对水稻半固体播种秧苗素质的影响

Effect of Concentrations of Compound Fertilizer on Seedling Quality in Semisolid Seeding of Rice

水稻半固体播种是一种全新的栽培方式。为实现水稻"高产、高效、高质"生产,研究了不同浓度复合肥对水稻秧苗素质的影响,结果表明,与对照相比,1∶100、1∶120、1∶140、1∶160、1∶180、1∶200的肥泥质量比例处理秧苗高度增加、整齐度适中、茎基部变宽、根系发育良好、干物质积累及分蘖增多、根冠比增大、叶片长势均匀,水稻秧苗素质明显提高,其中1∶120处理秧苗素质最优。1∶40、1∶80处理受到肥料毒害,秧苗细小、整齐度差、叶片发育不均匀,但干物质积累较多。而1∶20处理受到肥料的毒害最重,导致水稻无法出苗。

Semisolid seeding of rice is a new entirely way of cultivation pattern.In order to achieve the production goal of rice with “high yield,high efficiency,high quality”,this paper studied the influence of different concentration of compound fertilizer on rice seedling quality.The results show that,compared with the controlled,the treatments with fertilizer and mud quality proportion of 1∶100,1∶120,1 ∶140,1 ∶160,1 ∶180,1 ∶200 had positive effect on the rice shoot,mezzo uniformity, stem base width,root system development,higher biomass accumulation,root -shoot ratio,leaf growth,rice seedlings quali-ty,and the treatment with the proportion of 1∶120 is the best processing for the quality of seedling,and the treatment with the proportion of 1∶40 and 1∶80 processing had poisoned the seedlings,which made small,irregular seedlings and uneven leaf development,but accumulation of dry matter was more,the rice under the treatment with the proportion of 1 ∶20 couldn’t seedling since the rice suffered the heaviest poisoned by fertilizer.
