地膜穴播冬小麦品种生态型适应性研究

1996～1997年,在山西临汾就地膜穴播选用不同生态型冬小麦品种进行了研究。结果表明,地膜穴播条件下,不同生态型小麦品种的产量存在显著差异,旱地型＞扩浇型＞水地型;中穗型＞大穗型＞小穗型;冬型冬性＞冬型半冬性＞冬型强冬性

Adaptation of Different Varietal Ecotypes of Film-mulched and Bunch-seeded Wheat

Adaptation of different varietal ecolypes of film - mulched and bunch - seeded winter wheat was studied in Linfen, during 1996 ～ 1997. The results showed that there is significant yield difference among the varietal ecotypes. The yield order of different ecotypes is rainfed ＞ farultative ＞ irrigated for the water status, medium spike ＞ large spike ＞ small spike for the spike types and winter ＞ semi - winter ＞ 　Strong winte for the winter hardness.
