摘要
在马铃薯生长中期以不同浓度的多效唑溶液进行叶面喷施,研究多效唑对马铃薯农艺性状、产量及淀粉含量的影响。结果表明,马铃薯喷施多效唑能矮化植株,抑制地上茎杆生长,使植株叶色浓绿,增强光合作用,增加营养积累,促进薯块膨大,从而提高马铃薯的产量和淀粉含量,其中以喷施400 mg/L的15%多效唑溶液600 kg/hm2的处理效果最好,产量为16 572.22 kg/hm2,比对照增产3 516.66 kg/hm2,增幅为26.94%,淀粉含量最高达19.48%,比对照增长12.54%。
At medium-term growth stages of potato,different concentrations of paclobutrazol were sprayed on leaves to study its effect on the agronomic traits, yield and starch content of potato. The results showed that paclobutrazol could dwarf the plant,inhibit the growth of stem, make leaf green, strengthen the photosynthesis of leaf and nutrient accumulation, improve root tuber expanding, and increase the yield and starch content of potato. In all treatments,the effects of spraying concentration 400 mg/L of 15% paelobutrazol solution at rate of 600 kg/hm2 were the best, and the yield of potato reached 16 572.22 kg/hm2, and increased 26.94% compared to the control. The starch content was 19.48%, and increased by 12.54% compared with the control.
