根控肥（CULTAN）对小麦生长发育及品质的影响

根据德国波恩大学Sommer教授提出的CULTAN的原理与山西临汾研究了根控肥和传统施肥处理对小麦生长发育及品质的影响,结果表明:根控肥处理比传统施肥处理不论从小麦的生长发育,还是品质方面都表现出较好的优势,尤其是硫铵、尿素和DCD添加剂混合物的根控肥处理其面团的吸水率、稳定时间和评价值明显提高.同时根控肥处理土壤剖面中碱解氮的含量显著高于传统施肥处理.因此在生产优质强筋小麦的地区,应推广施用根控肥,达到优质小麦产量与品质的协调统一.

Effect of fertilizer controlled by root growth on winter wheat growth development and quality

According to the principle and recipe of CULTAN(Controlled uptake long term ammonium nutrition)presented by Professor Sommer,combined with local fertilizer resource and fertilizer application,the effect of fertilizers controlled by root growth and traditional fertilizers on wheat growth development and quality was studied in Linfen.The results showed that the treatments of fertilizer controlled by root growth with the mixture of ammonium sulfate,DCD and urea as fertilizer increase water absorption rate,stable time and valorimeter value of wheat dough and the content of available N in the soil profile,compared with the traditional fertilizer.Therefore,in high-gluten winter wheat planting regions,extending usage of CULTAN can achieve harmony between yield and quality.
