- 摘要:
- 选用黑龙江省四个不同生态类型小麦品种,对其在整个生育期间的叶面积及干物质动态变 化过程进行了系统的研究。结果表明:各类型品种间叶面积的动态变化和干物质积累动态存在明 显差异。旱肥类型、抗旱类型在生产中以个体的良好发育达到高产,而喜肥类型、耐湿类型则要求 水肥条件好时以群体的多穗多粒实现高产。
- Abstract:
- Study on the Dynamic Accumulation Character of LA and DM and in Spring Wheat Cultivar with Different Eco-typeAbstract: Four different eco- type genotypes of Heilongjiang were used in the study. The dy-namic of LA and DM accumulation were studied in whole growing period systemically, the resultshowed that there was significant diffe,rence between LA and DM accumulation for the every vari-ety of types. Fertility-drought type and drought-resistance type reached to higher yield in pro-duction due to better development of single plant, fertility type and wetness-tolerance neededbetter water and fertilizer condition for high-yielding by more ears and grains of populations.
