中文摘要	多点试验结果表明：（1）水稻覆膜旱栽，与不覆膜旱栽（CK1）比较，增产明显，增产幅度在7.3%，增产效果表现为干旱半干旱区>半干旱半湿润区>湿润区；与普通水田栽培（CK2）比较，北方的陕西，黑龙江试点增产7.6%，南方浙江试点的产量基本持平。（2）覆膜旱栽水稻，分蘖发生早，生长快，分蘖量大，群体茎蘖数增长迅速，达到最高茎蘖数的时期明显提前，株高增加，成熟期提早，每hm^2有效穗数比CK1增加48.8-247.5万，比CK2增加种植密度可以提高覆膜稻的成穗率，（3）覆膜旱栽水稻孕穗期的单丛叶面积与干物重比CK1和CK2明显增加；并且与CK2比较，根干重的增幅明显大于地上部干重的增幅，但成熟期草干重的增量也明显大于谷干重的增量。
英文摘要	Multi-location experiments were conducted to study the effects of planting rice in plastic film mulched dryland (PFMD) on growth and yield formation in rice. The results showed that .compared with the unmulched control(CKl) ,PFMD increased rice yields by 7. 3%-467- 8% , depending on the lo-cations. Regions differing in dryness.if ranked in descending order according to the efficiency of PFMD in improving rice yield,were as follows: the arid and semi-arid region,the semi-arid and semi-humid re-gion and the humid region. In comparison with the conventional paddy management (CK2), PFMD in-creased yield of rice by 7. 6%-25. 6% at selected locations in the northern part of China, such as Hei-longjiang and Shanxi provinces, but gave about the same yield as the control in the south,such as Zhe-jiang Province. Rice plants grown in PFMD had, in average, (48. 8-247. 5) X lOVhm2 more effective panicles than CK1 and (12. 3-S1. 5)X104/hmz more than CK2> which might be due to earlier tillering and more tillers per plant in PFMD. Furthermore .total leaf area and dry matter per hill in PFMD was larger than in both CK1 and CK2. It should be pointed out that there were some disadvantages for PFMD such as slower heading, lower effective panicle rate,larger variation in spikelets per panicle and unsteady filled grain rate.
