为了更好地评价新型肥料在黑龙江省水稻生产中的施用效果,利用大田区域联合试验的方法,通过将新型复合肥与常规肥料进行对比,研究新型复合肥的施用对不同积温带水稻生长发育及产量的影响。结果表明:施用复合肥处理较常规对照在佳木斯增产4.08%,在哈尔滨减产7.49%,且差异显著,在二九一农场减产5.18%。由于有效穗数和每穗粒数下降引起减产,每穗粒数和千粒重增加导致增产。在成熟期,施用新型复合肥使佳木斯的干物质增加5.15%,而哈尔滨和二九一农场的干物质分别下降4.95%和3.89%。与常规对照相比,复合肥处理使佳木斯的氮肥偏生产力增加4.08%,而哈尔滨和二九一农场的氮肥偏生产力分别降低7.49%和5.18%。表明,该新型复合肥在黑龙江省不同水稻种植区域的应用效果存在一定差异。
In order to evaluate the application effect of new fertilizers in paddy rice production in Heilongjiang Province, the new compound fertilizers were compared with those of conventional fertilizers by the method of field experiments in different fields to study the effects of new compound fertilizers on the growth and development, The impact of production. The results showed that compared with the conventional control, the compound fertilizer application increased the yield by 4.08% in Jiamusi and 7.49% in Harbin, with a significant difference and the yield reduction by 5.18% in 291 farm. As a result of the decrease of effective panicles and grains per panicle, the yield per panicle and 1000-grain weight increase. At maturity, the application of new compound fertilizers increased the dry matter content of Jiamusi by 5.15% while the dry matter content of Harbin and 291streets decreased by 4.95% and 3.89% respectively. Compared with the conventional control, compound fertilizer treatment increased the partial productivity of nitrogenous fertilizer in Jiamusi by 4.08%, while the partial productivity of nitrogenous fertilizer in Harbin and 291streased 7.49% and 5.18% respectively. The results showed that there was a certain difference in the application effect of the new compound fertilizer in different paddy planting areas in Heilongjiang Province.
