蚯蚓粪酒糟基质对水稻机插秧育秧的效果

Effect of Earthworm Dung and Cassava Distiller’s Grains Matrix on Rice Seedling by Machine Transplantation

[目的]解决木薯酒糟基质水稻育秧在实际生产过程中带来的一系列问题。[方法]将蚯蚓粪与木薯酒糟基质按照不同的体积比进行复配,设置4个处理,分别为A(蚯蚓粪:木薯酒糟基质1∶1)、B(蚯蚓粪∶木薯酒糟基质1∶2)、C(蚯蚓粪∶木薯酒糟基质1∶4)以及CK(木薯酒糟基质),通过好氧发酵后,进行水稻育秧试验。[结果]木薯酒糟基质中添加蚯蚓粪对水稻秧苗生长的各项指标都有明显的促进作用,但并非是蚯蚓粪添加比例越高,秧苗质量越好。当添加比例为蚯蚓粪∶木薯酒糟基质=1∶1时,其秧苗密度、成秧率、根数、根系盘结力和干物质积累都会有所下降;以蚯蚓粪∶木薯酒糟基质=1∶2时效果最理想。[结论]该研究可为蚯蚓粪在水稻育秧生产中的使用提供科学依据。

[Objective]To solve a series of problems brought by rice seedling with cassava lees matrix in the actual production process.[Method]Earthworm dung and cassava distiller’s grains matrix were compounded according to different volume ratios.Four treatments were set up,namely A (Earthworm dung ∶cassava distiller’s grains matrix 1 ∶1),B (Earthworm dung ∶cassava distiller’s grains matrix 1 ∶2),C (Earthworm dung:cassava distiller’s grains matrix 1 ∶4) and CK (cassava distiller’s grains matrix).After aerobic fermentation,rice seedling experiment was carried out.[Result]The addition of earthworm manure in cassava distiller’s grains matrix could obviously promote the growth of rice seedlings,but it was not that the higher the proportion of earthworm manure added,the better the quality of rice seedlings.When the proportion of earthworm dung ∶cassava distiller’s grains matrix was 1 ∶1,the seedling density,seedling rate,root number,root binding capacity and dry matter accumulation would decrease;when the proportion of earthworm dung ∶cassava distiller’s grains matrix was 1 ∶2,the effect was best.[Conclusion]This study can provide scientific basis for the application of earthworm manure in rice seedling production.
