摘要 试验采用"3414"完全实施方案,系统地研究了氮磷钾肥单因子、二因子及三因子互作对甜荞麦生育进程及农艺性状的影响。采用处理N_2P_2K_2、N_1P_2K_1、N-1P_2K_2可以使甜荞麦较早成熟,从而降低霜冻的威胁,可提前1~2 d进入生殖生长。N、P、K单施或配施在一定范围内均可以达到增加株高、茎粗、有效分枝数、主茎节数及节间长度的效果,过量施用则会对这些农艺性状产生抑制作用。 Adopting the full implementation plan "3414",research in the impacts that the single, double and three factors of N,P,K and interaction on the development progress and agronomic characters were done.Under these experimental conditions,N_2P_2K_2, N_1P_2K_1 and N_1P_2K_2 made buckwheat ripe earlier so that the threat of frost damage was decreased. And reproductive growth will be 1~2 days in advance. Both single fertilizer and cooperation of N, P, K fertilizer can achieve the effects of increasing plant height, stem diameter, number of effective branches, number of main stem section and internode length within certain amounts. However, excessive fertilizer will inhibit these agronomic characters.
