摘要
为了给黑龙江省小麦生产提供施肥依据,研究了黑龙江省小麦东部主产区施用钾肥对小麦品质和产量的影响。结果表明:适量的钾肥可增加小麦的株高、稳长、茎粗,延长面团的稳定时间,提高面粉的粉质质量指数,提高小麦的品质,产量较对照增加6．64%。兼顾产量与品质两个方面,在黑龙江省东部白浆土小麦主产区春小麦的适宜钾肥施用量为66．7～88．9kg／hm^2。
In order to provide the basis fertilizer principle for wheat production in Heilongjiang Province, the effect of different potassium fertilize application rates on the quality and yield of wheat in the east main wheat production area of Heilongjiang Province was studied. The results showed that the proper application rates of chemical potassium increased the plant height, the ear＇s length and the stem ＇s thickness, lengthened the development time of the dough, enhanced the quality index of the flour, improved wheat＇s quality, and increased the yield by 6.64%. Considering both quality and yield, the suitable amount of potassium fertilizer for the spring wheat was 66.7- 88.9 kg/hm^2 in eastern Albic soil main production area of Heilongjiang Province.
