机穴播密度对申优17大田生长和产量的影响
Effects of Different Mechanical Hill-seeding Density on the Growth and Yield of Hybrid Rice Shenyou 17
摘要
Abstract
[Objective] To find out the most suitable mechanical hill-seeding density of Shenyou 17. [Method] We researched the effects of mechanical hill-seeding density on leaf age, green leaf number, plant height, tiller dynamics, yield and its components. [Result] Mechanical hill-seeding density showed no significant impacts on the leaf age, green leaf number and plant height of Shenyou 17. Relatively high mechanical hill-seeding density could lead to enough ear number, and finally obtain relatively high yield. [Conlcusion] Under the current environment of Chongming District, the suitable hill-seeding density of Shenyou 17 was hill spacing 18 cm.关键词
