【摘要】 为促进植物生长调节剂在谷子生产中的应用,本试验选用公矮5号和红谷09-1两个谷子品种为试验材料,采用大田随机区组设计,在拔节期分别喷施3种浓度的S₃₃₀₇和GA,研究其对谷子抗倒性和产量的影响。结果表明:与对照相比,S₃₃₀₇对公矮5号和红谷09-1的株高有抑制作用;增加了两个品种植株茎粗;公矮5号的75mg·L^-1S₃₃₀₇处理增产15.6%,显著高于CK,红谷09-1的50mg·L^-1 S₃₃₀₇处理增产25.7%,极显著高于CK。与对照相比,GA对两个品种的株高和茎粗都有促进作用;公矮5号的产量最大值是10mg·L^-1 GA处理,增产10.4%,但与CK差异不显著,红谷09-1的产量最大值是30mg·L^-1 GA处理,增产20.2%,显著高于CK。更多还原

【Abstract】 In order to promote the application of plant growth regulators in millet production,Gongai No.5 and Honggu 09-1,were used as test materials.The field randomized block design method was used to spray S₃₃₀₇ and GA at jointing stages to study the resistance to millet and yield impact.The results showed that S₃₃₀₇ had an inhibitory effect on the plant height of Gongai No.5 and Honggu 09-1 compared with CK;the stem diameters of the two plants were increased;the 75 mg·L^-1 S₃₃₀₇ treatment of Gongai No.5 increased the yield by 15.6%,and reached a significant difference to CK.The 50 mg·L^-1 S₃₃₀₇ treatment of Honggu 09-1 increased the yield by25.7%,and reached a significantly different level to CK.GA could promote the plant height and stem diameters of the two varieties compared with CK;the maximum yield of Gongai No.5 was 10 mg·L^-1 GA treatment,increasing the yield by 10.4%,but it did not reach the level of significant difference to CK,the maximum yield of Honggu 09-1 was 30 mg·L^-1 GA treatment,which increased production by 20.2%,and reached significant difference to CK.更多还原
