摘 要：
为研究种植模式、插秧密度对辽西盐碱土壤水稻产量性状的影响,本文采用覆膜机插秧和常规机插秧两种种植模式、3种插秧密度进行试验。结果表明:覆膜能促进水稻早生快发,促进茎蘖增长,覆膜机插秧水稻的穗粒数、结实率、千粒重、有效穗数等产量性状均有较大幅度提高,从而促进水稻产量水平显著提升;不同插秧密度间,水稻产量及相关性状差异较大,产量和有效穗数随插秧密度增大而提高,表明在盐碱土壤适当提高插秧密度有利于产量性状优化及水稻产量提高。在辽西盐碱土壤,覆膜机插秧种植水稻密度行距30 cm时,株距以10～16 cm较为适宜。

摘 要：
To study effects of the planting pattern and the planting density on the yield and its characters of rice planted in saline soil in Western Liaoning, in this paper,3 transplanting densities with film-covering & transplanting by machine and transplanting by machine were tested. The results were as follows. The rice could grow earlier and faster in film-covering field than in bare field. With grain number per panicle, setting rate, 1,000-grain weight and the number of effective panicle being higher, film-covering rice had higher yield. Rice yield and its characters were significantly different between 3 transplanting densities, further, the yield and effective panicle number would increase with the transplanting density getting larger. As a conclusion, the proper larger transplanting density can promote the rice yield in saline soil,& the better density of rice planted in film-covering saline soil in Western Liaoning is the planting-space 10-16 cm with row space 30 cm.
