0.3%氯化血红素可湿性粉剂对马铃薯生长及安全性评价

Evaluation of 0.3%Heme Chloride WP on Potato Growth and Safety

分析了0.3%氯化血红素可湿性粉剂对马铃薯生长的影响及其安全性。结果表明,0.3%氯化血红素可湿性粉剂可以调控马铃薯的生长,随着用量的增加,不仅可以促进植株大薯数和产量增加,其中大薯数增长率为7.2%~15.7%,产量增长率为3.6%~8.8%,还能增强马铃薯的抗病性和叶绿素含量,其中防病率为4.9%~41.0%,叶绿素增长率为19.4%~27.3%。综合分析表明,0.3%氯化血红素可湿性粉剂在马铃薯田间种植中具有较好的应用前景,从用药的经济性和安全性考虑,推荐0.3%氯化血红素可湿性粉剂有效成分用量为0.9~1.35 g/hm^(2)。

The growth and safety evaluation of 0.3%heme chloride wettable powder(WP)on potato were analyzed.The results showed that 0.3%heme chloride WP could regulate the growth of potato,and with the increase of dosage,it could not only promote the increase of plant large potatoes and yield,in which the growth rate of large potato number was 7.2%-15.7%and yield growth rate was 3.6%-8.8%,but also enhance the disease resistance and chlorophyll content of potato,in which the disease prevention rate was 4.9%-41.0%and chlorophyll growth rate was 19.4%-27.3%.In terms of economics and safety,the recommended dosage of 0.3%heme chloride wettable powder is 0.9-1.35 g/hm^(2) of active ingredient.
