ZS型新育秧药对水稻育秧效果的初步研究
Preliminary study of ZS new seedling-agent on growth of rice seedling
【摘要】 应用植物生长调节剂GA、NAA、6 -BA、PG1和PG2 对水稻浸种育苗进行初步试验 ,在此基础上 ,新研制育秧药 (由不同植物调节剂和杀菌剂及营养物组成 )ZS1 # 、ZS2 # 、ZS3# ,并对水稻进行了浸种、塑盘育秧试验研究 .试验结果表明 :( 1 )用药水稻秧苗假茎粗比对照增加 2 8.9%以上 ;( 2 )用药秧苗根数比对照增加近 1倍 ,白根数比对照增加 94 .9%~ 1 39.7% ;( 3)应用ZS2 # 、ZS3# 增加了水稻秧苗植株分蘖 ;( 4 )用药秧苗干重比对照增加2 0 %以上 ,矮壮指数增加 7.8%~ 35.2 % .ZS育秧药促使壮秧健苗 ,促进秧苗前期生长发育 ,也益于秧苗后期生长 .
【Abstract】 The new seedling agent- ZS1 #、ZS2 #、ZS3 #, which are the mixture consisted of different plant growth regulators and fungicide, are applied to growth of rice seedling with using plastics seedling on the basis of the preliminary test study of plant growth regulators GA、NAA、6-BA、PG 1and PG 2 on the growth of rice seedling by soaking seed. The results of the test study shows: (1) the average stalk wide of rice seedling by using ZS # is raised by 28.4%~65.1% compared with CK (soaking seed with water); (2) the average root number of rice seedling is raised by nearly 100%, the ratio of the white root is raised by 94.9% ~139.7% compared with CK; (3) the tillering of rice seedling is promoted by using ZS2 #、ZS3 #;(4) the weight of the dry rice seedling is raised by above 20% and the ratio of the weight of dry rice seedling to the height of rice seedling is raised by 7.8%~35.2% compared with CK. Rice seedling is stronger and it is advantage to the rice seedling growth later by using the new seedling-agent.
