| 摘 要： | 在潮土上采用田间小区试验,研究了钴元素对小麦产量和品质的影响。结果表明:施用适量的钴可以显著提高冬小麦的产量,改善冬小麦的品质。各施钴处理较对照增产7.4%～20.3%。施钴量在1.05kg.hm2以内,随着施钴量的增加,增产效应提高,当施钴量超过1.05kg.hm2时,随着施钴量的增加,冬小麦的产量增加,但增产效应下降。各施钴处理子粒蛋白质含量与蛋白质产量均有不同程度的提高,以Co2处理最高。此外,低浓度的钴(施钴量0.45～0.75kg.hm2)可以提高冬小麦子粒面粉的沉降值、总评价值和湿、干面筋含量,而高浓度的钴(施钴量大于1.35kg.hm2)则降低冬小麦子粒面粉沉降值、总评价值和湿、干面筋含量。土壤有效钴含量与施钴量呈极显著正相关,小麦籽粒中钴含量与施钴量呈显著正相关,地下部的钴含量显著大于地上部。

| Abstract: | A plot experiment was conducted to study the effect of cobalt on yield and grain quality of winter wheat by the design method of complete random block. The main results were summarized as follows: cobalt application increased wheat yields compared with control, and the greatest enhances were Co 1.05kg/hm2. Lower concentration of cobalt (0.45—0.75kg/hm2)improved grain quality(crude protein content, sedimentation value, wet gluten content, dry gluten content and valorimeter value) and higher addition of Co (over 1.35kg/hm2) resulted decrease in values of grain quality. Co content in wheat grain and DPTA-extractable cobalt in soil showed significantly positive correlation with soil-applied cobalt. Roots were significantly richer in cobalt than aerial parts. |
