摘要
在氮、磷固定的条件下,采用农业部推广的硅钾镁"3414"肥料设计进行多点试验,完善平衡配套施肥方案,建立不同品种的硅、钾、镁施用纯量与产量的效应函数模型,以期为寒地增产保优合理施肥提供科学依据。结果表明:不同品种的硅、钾、镁施用纯量与产量的效应函数模型不同;缺硅、缺钾、缺镁对水稻产量及产量构成因素的影响不同,同一地点不同品种对缺素表现出了相同的规律,钾对产量影响最大,其次是缺硅,影响最小的是镁‘;空育131’、‘垦粳1号’的处理6(Si2K2Mg2)、处理9(Si2K2Mg1)、处理10(Si2K2Mg3)、处理13(Si1K2Mg1)产量都较高。‘空育131’处理13(Si1K2Mg1)产量最高为9173.10kg/hm2;‘垦粳1号’处理9(Si2K2Mg1)产量最高为9162.45kg/hm2。因此,要做到良种良法配套必须测土并针对品种进行施肥,才能达到高产优质的目的。
＂3414＂ about Silicon Potassium and Magnesium design which the ministry of agriculture of China popularized was used to complete balanced supporting fertilization program under the condition of the same nitrogen and phosphorus.Through the establishment of silicon,potassium,magnesium application and yield effects function model of different,the aim was that provide a scientific basis for applying fertilizer which in order to increase yield and improve quality of rice in cold region.There came to conclusion that different varieties had different effect function model.The effects of lack Silicon Potassium and Magnesium on the yield and constitute factor were different.The rule of different species of lack element performance on the same location,the effect of Potassium on yield was the greatest,followed by lack of Silicon fertilizer and influence of Magnesium was the smallest.The yield of ＇Kongyu131＇ and ＇Kenjing 1＇ of the treatment six （Si2K2Mg2）,nine （Si2K2Mg1）,ten （Si2K2Mg3）,thirteen （Si1K2Mg1） were higher than others.The yield of ＇Kenjing 1＇ of the treatment nine （Si2K2Mg1） was the highest （9162.45 kg/hm2）,and ＇Kongyu131＇ was the treatment nine （9162.45 kg/hm2）.Therefore,in order to achieve the purposes of high yield and quality,soil testing and matching for fertilizers of different varieties should to be done to achieve supporting excellent seed with excellent method.
