本文研究了在江苏淮北地区不同钾肥用量对优质面包专用型小麦苏徐1号产量的影响,同时通过长期定位试验研究了增施钾肥对苏徐1号产量及品质的影响。钾肥用量试验结果表明,施用钾肥可增加产量8.3%～13 7%,适宜的钾肥用量为90～135kgK2O/hm2,最佳经济钾肥施用量为135.6kgK2O/hm2,其产量为5056.1kg/hm2,长期定位试验结果表明,施用钾肥可提高苏徐1号的商品品质,在长期不施有机肥(厩肥)的情况下,增施钾肥可改善面粉的加工品质,提高其评价值。
In this paper, the effects of different potash dosages on the yield of high-quality bread wheat Su Xu 1 were studied in Huaibei area of Jiangsu province. At the same time, the effects of increasing potassium fertilizer on the yield and quality of Suxu 1 were studied through long-term experiment. The results of potash fertilizer application show that potassium fertilizer can increase the yield by 8.3% ~ 13.7%, the suitable potash fertilizer is 90 ~ 135kgK2O / hm2, the optimum economic potash fertilizer is 135.6kgK2O / hm2, the yield is 5056.1kg / hm2, Positioning test results show that the application of potassium fertilizer can improve the quality of Su Xu 1 commodity, long-term without organic fertilizer (manure), the increase of potassium fertilizer can improve the processing quality of flour and improve its evaluation value.
