摘要
SPR_1—8301植物生长刺激素的实验室试验结果表明:SPR_1—8301浓度为100、150PPm比对照区鲜重分别提高4％和21.3％。并有一定的防病效果。田间试验结果表明:应用10％SPR_1,以种子重量0.8％拌种和SPR_1粉原PPm200PPm、浸种后,甜菜块根产量平均比对照增加23.08％,含糖率平均提高0.3％,产糖量平均增加23.33％.
The laboratory test showe that a plant-growth substance named SPR1-8301 can promote the growth of sigarbeet seedlings. Comparing with the contrast, the fresh wight is increased by 4% with 100ppm and the fresh wieght is increased by 21.3 %with 150ppm. The concentration of SPR1-8301 powder is 100-150ppm.The field experimental result shows that using 10% SRR1-8301 seed dressing and SPR1-830l powder 150ppm, 200ppm seed soaking, the sugarbeet root yield is increased by 23.08% comparing with the contrast,■he sugar content is increased by 0.3% and the sugar yield is increased by 23,33%.
