摘要
为探索不同床土与水稻育壮秧的关系，本文通过１９８６～１９９１年，进行了不同配比的堆积法培养床土和五种常用的床上水稻育壮秧的试验示范。结果表明：堆积法培养床土能够改善床土的理化性质，创造了适宜水稻幼苗生长的生活条件。与其他床土育苗比较，明显地提高了水稻幼苗的叶龄、茎粗、根数、根长，增加了地上部干重、充实度、带蘖率和产量。同时总结应用堆积法培养床土育壮秧创高产的经验，并提出堆积法培养床土的关键技术措施。
To understand the effect of different bed soil on raising strong seedlings, the author of the article did some experiments about raising strong seedlings on bed soils fostered by piling up with different ratio of ingredients and five kinds of collventional bed soil from 1986 to 1991. The resultd showed that the piling-up method could improve the physical and chemical characters of bed soil and present the proper living conditions for rice seedlings.Compared with other bed soils, the piled-up bed soil increased the leaf number, the stem thickness, the root number, the tillering frequency and the dry weight of rice seedlings and eventually increased the yield of rice. The practical experience about piling-up method was sumed up and the key techniques about fostering bed soil with piling-up method were presented.
