摘要: 在水稻育秧土壤中加入不同比例(0、2%、4%、6%、8%)的黑水虻虫粪,研究黑水虻虫粪对水稻秧苗农艺性状、生理特性的影响。结果表明:黑水虻虫粪可促进水稻秧苗的生长,秧苗株高、最大叶宽、茎宽分别增加了22.7%~45.7%、14.3%~36.9%、13.8%~21.9%;水稻叶片中氮磷钾含量、叶尿素含量、光合速率、可溶性糖含量及可溶性蛋白含量分别提高了14.3%~78.0%、26.2%~49.6%、29.3%~146.3%、9.5%~32.8%、40.7%~56.0%。在不同添加比例中,6%黑水虻虫粪处理的水稻秧苗最大叶宽、叶片氮磷含量、叶绿素、光合速率、可溶性蛋白含量都为最高;8%处理的秧苗叶片叶绿素、可溶性蛋白含量显著低于6%处理,其余指标与6%处理没有显著差异。说明黑水虻虫粪可用于水稻育秧基质,6%添加量为最佳。

Abstract: Different proportions (0,2%, 4%, 6%, 8%) of manure of black soldier fly were added to the rice seedling raising soil to study the effects of insect manure on agronomic and physiological characteristics of rice seedlings. The results showed that insect manure can promote the growth of rice seedlings, and that it increased plant height by 22.7%-45.7%, leaf width by 14.3%-36.9%, stem width by 13.8%-21.9%, and increased content of nitrogen, phosphorus and potassium by14.3%-78.0%, chlorophyll content by 26.2%-49.6%, photosynthetic rate by 29.3%-146.3%, soluble sugar content by 9.5%-32.8%, and soluble sugar content by 40.7%-56.0%. The maximum leaf width, leaf N, P, chlorophyll, photosynthetic rate and soluble protein content of 6% treatment were the highest. The chlorophyll and soluble protein content of 8% treatment were significantly lower than that of 6% treatment, and there was no significant difference among other indexes. The results showed that the black soldier fly manure can be used as rice seedling substrate, and 6% is the best.

Key words: rice seedling, black soldier fly manure, seedling quality, substrate
