【摘要】 不同DA-6施用量对菜心养分吸收和产量的影响试验结果表明:DA-6能促进养分吸收、叶绿素合成和植株生长,其中60 mg/kg处理茎围最大为10.8 cm,比空白对照增加18.16%,叶绿素含量最高,比对照增加24.38%,产量最高为4315.49 kg/hm2,比对照增产710.45 kg/hm2,相对增产26.74%。更多还原

【Abstract】 The field experiments of different DA-6 applied on flowering Chinese cabbage were conducted to study the nutrient absorption and yield.The results showed that the application of DA-6 could promote the nutrient absorption and chlorophyll synthesis.Compared with the control,the 60 mg/kg DA-6 sprayin increased not only the stem girth and chlorophyll content by 18.16% and 24.38% respectively,but also the nutrients absorption and accumulation,and the yield by 26.74%.更多还原
