摘要
为了明确0.3%氯化血红素可湿性粉剂对马铃薯生长的调节效果,确定最佳用量,以克新6号马铃薯为材料,以8%甲哌鎓可湿性粉剂和清水分别作为药剂和空白对照,采取随机区组排列开展田间应用试验,分析不同用量0.3%氯化血红素可湿性粉剂配施专用助剂(SD)对马铃薯生长、产量及品质的影响。结果表明:处理1—处理5(667 m^(2)分别施用0.3%氯化血红素可湿性粉剂10、20、30、40、0 g,并配施SD 20 g)平均株高、全叶鲜质量、茎粗和小区平均产量均较空白对照有所增加,且均以处理4(667 m^(2)施用0.3%氯化血红素可湿性粉剂40 g+SD 20 g)最大,处理3(667 m^(2)施用0.3%氯化血红素可湿性粉剂30 g+SD 20 g)次之,2者小区平均产量较空白对照分别极显著增加13.80%、10.73%,但与药剂对照差异均不显著;处理1—处理5马铃薯块茎干物质量、淀粉含量、还原糖含量和VC含量等也均较空白对照有所增加,其中以处理4最高,处理3次之,2者均显著高于空白对照。安全性评价表明,各处理对马铃薯均是安全的。在马铃薯生产上,推荐每667 m^(2)使用0.3%氯化血红素可湿性粉剂30~40 g+SD 20 g。
In order to determine the regulating effect of 0.3%hemin wettable powder(WP)on potato growth and determine the optimal dosage,potato'Kexin No.6'was used as material,and 8%mepiquat chloride WP and clear water were used as pesticide control and blank control,respectively,and the field application experiment was carried out by random block arrangement to analyze the effects of different dosage of 0.3%hemin WP combined with special additives(SD)on growth,yield and quality of potato.The results showed that the average plant height,fresh leaf weight,stem diameter and average plot yield of treatment 1-treatment 5(applying 0.3%hemin WP 10,20,30,40,0 g and SD 20 g per 667 m^(2),respectively)were higher than those of blank control,and treatment 4(0.3%hemin WP 40 g+SD 20 g per 667 m^(2))was the largest,treatment 3(0.3%hemin WP 30 g+SD 20 g per 667 m^(2))was the second,and the average plot yield of the two treatments extremely and significantly increased by 13.80%and 10.73%than blank control,respectively,but there was no significant difference with pesticide control.The dry matter weight,starch content,reducing sugar content and VC content of tuber under treatment 1-treatment 5 also increased compared with the blank control,among which treatment 4 was the highest,followed by treatment 3,and both were significantly higher than the blank control and pesticide control.Safety evaluation showed that all treatments were safe for potatoes.In potato production,it was recommended to use 0.3%hemin WP 30-40 g+SD 20 g per 667 m^(2).
