棉粕腐植酸肥对小麦生长及产量的影响

为给棉粕腐植酸肥料在小麦上的应用提供参考依据,采用田间试验,以小麦新春38号为供试材料,研究了无机养分和棉粕腐植酸复合肥对小麦生长和产量的影响。结果表明,与不施肥处理和常规复合肥处理相比,施用棉粕腐植酸复合肥小麦的株高、叶面积、叶绿素、干物质均有所提高,分蘖和成穗率增加,产量显著提高,与不施肥处理和常规复合肥处理相比,产量分别增加了51.36%和13.56%。

Effect of Cottonseed Humic Acid Fertilizer on Growth and Yield of Wheat

As the cottonseed meal is a superior material resource protected in Xinjiang,to explore the effects of water soluble humic acid fertilizer produced with cottonseed meal on wheat growth and yield,field trial was conducted with Xinchun 38 as material,and three treatments were set up: CK,the same level nutrients of inorganic nutrients and the same level nutrients of humic acid compound fertilizer. According to the plot test experiments,the humic acid fertilizer in different growth period on yield and growth of wheat were explored. The results show that compared with CK and normal treatment,humic acid fertilize not only increases plant height,leaf area,chlorophyll,the dry matter,but also promote wheat tillering and spike number,which made the yield of wheat increased by 51.36% and 13.56%,respectively. Therefore,cottonseed meal humic acid fertilizer has played a significant role in promoting growth and increasing yield of wheat.
