| 摘 要： | 在北京地区进行了不同肥料种类、施肥量、施肥时间及比例的试验结果显示,秋施80kg/hm^2 P2O5＋春施160kg/hm^2 P2O5处理的潜在种子产量和实际种子产量达到最高,分别为2470.95kg/hm^2和820.65kg/hm^2。与其它处理相比,其单株花穗数、花穗上的小花数、可育小花数和千粒重均有显著提高。

| Abstract: | An experiment was carried out in Beijing from 2005 to 2006 to study the effects of nitrogen(N), phosphorus(P), potassium(K) and different models of application on the Astragalus adsurgens Pall.seed yield components and seed yield . The treatment P3 (80 kg/hm2 P2O5 in autumn 160 kg/hm2 P2O5 in spring )gets the maximum potential seed yield of 2470.95 kg/hm2 and seed yield of 820.65 kg/hm2; Treatment P3 can increase the amount of inflorescence number, florets number/inflorescence and pods number/racemes, thousand-grain weight significantly. |
