小麦专用腐殖酸控释掺混肥一次施肥效应

Single Fertilization Effect ofWheat Specific Controlled-release Humic Acid Mixed Fertilizer

以河南省粮食主产区冬小麦为试验对象,开展小麦专用腐殖酸控释掺混肥一次施肥效应研究。结果表明:与普通小麦肥一次性底施或普通小麦肥底施+追施相比,专用腐殖酸控释掺混肥一次性施肥处理小麦有效穗数增加3.0万~19.5万穗/hm^(2)、穗粒数增加0.4~2.6粒、千粒重增加0.8~2.5 g,产量增加6.10%~14.87%,增收1396.88~3018.32元/hm^(2);不同区域、不同土壤类型、不同品种有一定差异,但表现趋势高度一致,说明专用腐殖酸控释掺混肥养分释放规律与小麦生长需求吻合度较高,有利于农作物高产稳产。

Taking winter wheat as the experimental object in the main grain producing area of Henan Province,this paper studied the single fertilization effect of wheat specific controlled-release humic acid mixed fertilizer.The results showed that compared with the basal application of ordinary wheat fertilizer or the basal application+topdressing application of ordinary wheat fertilizer,the treatment with the basal application of wheat specific controlled-release humic acid mixed fertilizer increased the effective number of wheat ears by 30000 to 195000/hm^(2),the number of grains per ear increased by 0.4 to 2.6,the 1000-grain weight increased by 0.8 g to 2.5 g,the yield increased by 6.10%to 14.87%,and the income increased by 1396.88 yuan/hm^(2) to 3018.32 yuan/hm^(2).There were certain differences in different regions,soil types and varieties,but the trend was highly consistent,indicating that the nutrient release law of wheat specific controlled-release humic acid mixed fertilizer was highly consistent with the growth needs of wheat,which was conducive to high yield and stable yield.
