地膜穴播冬小麦生物学特性及其增产机理

Yield Increasing Mechanism and Biological Character of Dibbling Wheat in Film Mulched Field

试验表明，地膜穴播冬小麦具有显著的增产和节水作用，比对照增产２４．７６％；水分生产效率达１２．１５ｋｇ／（ｈｍ２·ｍｍ），比对照高４．９５ｋｇ／（ｈｍ２·ｍｍ），耗水量比对照减少８１．８４ｍｍ；各种生理活性指标均比对照显著提高；生育期提前７ｄ。

The experiment shows that dibbling wheat in film mulched fields can remarkably increase yield and save water. Wheat yield can be raised by 24.76% compared with that of the control group. The moisture productivity amounts to 12.15 kg/(hm 2·mm) ,which is 4.95 kg/(hm 2·mm) higher, and the water consumption reduces by 81.84 mm compared with that of the control; Its active physiological indices are all remarkably improved and its growing period becomes 7 days short.
