本文着重研究了营养诊断与平衡施肥对春小麦子粒（种子）几个主要性状指标的影响。结果表明：①在有限的调节次数内，穗粒数、结实率、千粒重与平衡施肥次数呈显著正相关；②调节１～３次，其种子生活力分别比ＣＫ提高３．０、４．２和７．２个百分点，发芽率分别提高４．１、４．９和９．７个百分点；③平衡施肥株高增加的意义表现出对穗粒数、结实率和千粒重的增加；其穗粒数和千粒重的增加分别占总增产的５７．１％～６３．７％和１２．９％～１８．６％。
This article focuses on nutrition diagnosis and balanced fertilization on the spring wheat grain (seed) several major traits indicators. The results showed that: (1) There was a significant positive correlation between spike grain number, seed setting rate and 1000-grain weight with the number of balanced fertilization within a limited number of adjustment times; (2) After adjusting for 1 to 3 times, the seed vigor was increased by 3.0,4.2 And 7.2 percentage points respectively, and the germination rate increased by 4.1, 4.9 and 9.7 percentage points respectively. (3) The significance of increasing fertilization plant height showed an increase in the number of grains per spike, seed setting rate and 1000-grain weight. The increase in number and 1000-grain weight accounted for 57.1% ~ 63.7% and 12.9% ~ 18.6% of the total increase respectively.
