试验于1983—1984年在新西兰 Pukekohe 进行。以加利福尼亚晚蒜为试材,分两个播期(6月15日和8月11日),探讨 N 肥水平(设0、30、60、120、240kgNh~(-1)),对植株生长发育机制的影响,以及土壤有效积温(GDD)与植株生育的关系。1N 肥水平对产量的影响在30—240kgNha~(-1)范围内,植株总干物质量与N 肥用量的自然对数值呈显著的线性关系,其相关方程为 Y(产量)=10.56+0.17In(N 肥水平),最
The experiment was conducted in Pukekohe, New Zealand, from 1983 to 1984. The experiment was conducted with California evening garlic as test material and two sowing dates (June 15 and August 11) to investigate the effects of nitrogen fertilizer (0, 30, 60, 120 and 240 kgNh ~ (-1) Developmental mechanisms and the relationship between soil effective accumulated temperature (GDD) and plant growth. The effect of 1N fertilizer on yield was in the range of 30-240kgNha ~ (-1). The total dry matter of plant was significantly linear with the natural logarithm of N fertilizer, and the correlation equation was Y (yield) = 10.56 + 0.17In (N fertilizer level), the most
