摘要
绿色智能肥料(GIF)是为响应工业绿色制造与农业绿色可持续生产提出的肥料新理念,以GIF的理念为指导生产了水稻GIF,并评价了该肥料在水稻上的农学应用效果。在氮磷养分等量投入的前提下,在大田设置常规氮磷钾肥料(T1)、复合肥1(T2)、复合肥2(T3)、GIF1(T4)和GIF2(T5)5种肥料施用处理,研究不同肥料品种对水稻产量、产量构成因素、干物质积累、根系生长发育、叶片光合特性、籽粒品质、土壤pH、氮磷养分积累量及肥料经济效益的影响。与常规肥料(T1、T2、T3)相比,T4主要通过增加水稻有效穗数实现了增产作用,较T1、T2和T3分别增产26.2%、28.4%和38.1%。T5主要通过增加有效穗数、稻穗二次支梗穗粒数和粒重实现增产,较T1、T2和T3分别增产38.3%,39.0%和51.4%。相比常规肥料(T1、T2、T3),T4和T5处理显著提高水稻地上部干物质积累量、功能叶SPAD值、土壤pH、氮磷养分含量及积累量,同时促进了水稻根系生长发育且获得较高的产投比。与T1相比,两款常规复合肥(T2、T3)并未对水稻产量及其他农艺性状表现出增效作用。水稻GIF肥对水稻生长、产量和品质提高有显著增效作用,相比常规肥料具有更高的经济效益。
Green intelligent fertilizer(GIF)was a new fertilizer concept proposed in response to industrial green manufacturing and agricultural green sustainable production.The rice GIF was produced under the guidance of the concept of GIF.In order to evaluate the agronomic performance of this fertilizer on rice,under the premise of equal input of nitrogen and phosphorus nutrients,five kinds of fertilizers were set up:conventional NPK fertilizer(T1),compound fertilizer 1(T2),compound fertilizer 2(T3),GIF1(T4)and GIF2(T5).The effects of different fertilizer varieties on rice yield,yield components,dry matter accumulation,root growth and development,leaf photosynthetic characteristics,grain quality,soil pH,nitrogen,phosphorus nutrient uptake and fertilizer economic benefit were studied.Compared with conventional fertilizer(T1,T2 and T3),T4 increased rice yield by 26.2%,28.4%and 38.1%,respectively,by increasing the effective panicle number of rice.T5 increased the yield by increasing the number of effective panicle,the number of grains per spike of secondary branches and grain weight,which was 38.3%,39.0%and 51.4%higher than that of T1,T2 and T3,respectively.Compared with conventional fertilizer(T1,T2 and T3),T4 and T5 treatments significantly increased above-ground dry matter accumulation,functional leaf SPAD value,soil pH,nitrogen and phosphorus nutrient content and accumulation,and promoted root growth and development of rice with a higher yield to investment ratio.Compared with T1,the two conventional compound fertilizers(T2 and T3)showed no synergistic effect on rice yield and other agronomic traits.Rice GIF had significant synergistic effect on the growth,yield and quality of rice,and had higher economic benefits than conventional fertilizer.
