中文摘要	通过盆栽和大田试验研究了水和磷互作对旱作水稻生物量和产量的影响.研究表明:土壤含水量和施磷量对旱作水稻生物量和产量有极显著的影响,且二者的交互作用十分明显,影响程度以籽粒＞茎＞根.土壤含水量为饱和持水量的60%时对旱作水稻生物量和产量影响较大,而80%和100%时几乎没有影响.旱作水稻生物量和产量均随施磷量的增加而增加.这说明控制土壤水分为饱和持水量的80%时就能完全满足旱作水稻的生长,但要求获得较高的产量时必须注意磷肥的投入,或者采取一些调控措施提高土壤磷的利用率.
英文摘要	Both field and pot experiments were carried out lo study effects of interaction between soil moisture content and P application rates on hiomass and yield of rice cultivated in aerobic soil. The results show that the effects of soil moisture content and P application rale were significant on biomass and yield of rice growing in aerobic soil, and the interactive effect of the two factoi-s was veiy evident, showing a sequence of grain > ahoot > root. Although the biomass arid yield of rice had been hardly af-fecled by soil moisture content, when it was 80% or 100% of saturated water content (SWC) , but markedly by soil moisture content 60% of SWC. Biornass and yield of rice increased with the increasing in P application rate in the aerobic soil, showing that the soil moisture content 80% of SWC was enough lo maintain rice growth in the aerobic soil. In order to gain higher yield of rice, it is essential to pay attention to P application or take some measures lo improve soil P utilization efficiency.
