| 摘 要： | 通过温室盆栽和大田试验研究了土壤含水量和施磷量对旱作水稻全磷吸收量的影响。结果表明:土壤水分和施磷量对大田旱作水稻全磷吸收量的影响不显著;对盆栽而言,施磷量的影响显著,但二者的交互作用明显,因而其差异主要体现为水和磷的复合效应;当施磷量(P)为0·030gkg-1、土壤含水量为饱和持水量的80%时旱作水稻吸磷量最高,但相同土壤水分条件下,施磷与不施磷间旱作水稻吸磷量差异最大,而不同施磷量间差异较小;旱作水稻各部分全磷平均吸收量为:籽粒>茎>根。实验结果可以为中国南方丘岗地区水稻旱作的水分和磷素管理提供理论依据。

| Abstract: | Pot experiments in a glasshouse and field experiments were conducted to investigate effects of soil moisture content and phosphorus (P) supply on total P uptake by rice cultivated in aerobic soil. Results showed that soil moisture and P application did not affect significantly total P uptake by rice cultivated in aerobic soil in the field experiment. But in the pot experiments,P application increased significantly P uptake by the rice plants,though the effect of soil moisture was not significant. A big interaction between soil moisture and P application was founded. And,thus,the highest P uptake by the rice plants was found in the treatment with 0. 0300 g kg~ -1 of P application rate and 80 % in saturated water content. The biggest difference of total P uptake by the rice plants was observed between the application and no application of P under 80 % of soil saturated water content and the difference of P uptake by the rice plants between different P application rates was less. Distribution of the P taken up by the rice plants,was in the following order: grain>shoot>root. The results obtained in this experiment could serve as a theoretic basis for water and P management of rice cultivated in aerobic soil in the hilly areas of Southern China. |
