机穴播密度对申优17大田生长和产量的影响
|
摘要
[目的]探索申优17最适宜的机穴播密度。[方法]研究机穴播密度对申优17叶龄、绿叶数、株高、茎蘖动态、产量及其构成因素的影响。[结果]不同机穴播密度对申优17叶龄、绿叶数和株高均无明显影响;较高的穴播密度易形成足够的穗数,最终获得较高的产量。[结论]在崇明区当前的环境下,申优17的适宜机穴播密度为穴距18 cm。
[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.
