黄粉虫粪沙不同用量对油菜生长及品质的影响

Effects of Different Application Amount of Yellow Mealworm Excrement on Growth and Quality of Rape

利用盆栽试验研究了黄粉虫粪不同施用量对油菜生长及品质的影响。黄粉虫粪分别按土壤重量的01、.5%、2.5%3、.5%与土壤混合均匀。结果表明1,.5%黄粉虫粪处理油菜产量最高。黄粉虫粪不同用量对油菜光合速率、叶片养分含量及品质无显著影响,表明黄粉虫粪对油菜的增产作用除了其中的营养元素,还有其它因素起重要作用。

The pot experiment was Yellow Mealworm excrement on the growth conducted to study the effects of different application amount of and quality of rap. The yellow mealworm excrement was mixed with soil according to the ratio of 0, 1.5%, 2. 5% and 3.5%. The results showed that the rape plants had the highest yield after treated by the yellow mealworm excrement mixed with soil according to the ratio of 1.5%. The effects of different application amount of yellow mealworm excrement on photosynthetic rate, nutrient concentrations and quality of rape were not significant, indicating that the improving effect of yellow mealworm excrement on the productivity of rape plants caused not only by the nutrient elements in yellow mealworm excrement but also by other factors.
