摘要
以泥炭为主的普通基质为对照,研究了以芦苇残渣、畜牧粪便、碳化稻壳等废弃物为主要原料的有机废渣基质对水稻秧苗农艺和生理性状的影响。结果表明:2种育秧基质处理的水稻秧苗的主要农艺性状和生理指标,除根系总吸收面积和不定根数2个指标外,有机废渣基质处理的秧苗均优于对照,且差异达显著水平。利用有机废渣为主要原料配制水稻育秧基质,生产成本减少约10元/667m2,有利于推广应用。
The ordinary peat-based substrate was used as control to study the effect of the organic waste residue substrate, such as reed residue, livestock manure, carbonized rice hull waste, on the agronomic traits and the physiological indexes of rice seedlings in factory. The results showed that in comparison with control, the main agronomic traits and the physiologic indexes of rice seedling treated with the organic waste residue substrate were better and the differences reached significant level, except for total absorption area of the root system and adventitious root number. Utilizing organic waste residues as the main raw material for the preparation of rice seedling substrate can reduce the production cost by 150 yuan/hm2, which is conducive to the promotion and application.
