| 摘 要： | 为明确夏玉米施用海藻酸复混肥的增产效果,通过田间试验,以‘浚单29’为材料,利用数理统计、对比分析方法,研究了海藻酸包膜BB肥、常规BB肥、海藻酸包膜复合肥、常规复合肥4种肥料对鹤壁和许昌两地夏玉米产量、地上部生物量、养分积累量、SPAD值等的影响。结果表明,鹤壁和许昌夏玉米施肥分别显著增产8.80%~15.41%和21.21%~35.85%,海藻酸包膜BB肥较等养分常规BB肥分别增产5.70%和5.22%;海藻酸包膜复合肥较常规复合肥产量显著增加5.98%和13.37%,施海藻酸复混肥提高了夏玉米叶绿素含量,促使氮磷钾养分积累量分别增加3.76%~17.03%、6.29%~27.14%和3.70%~9.33%,协同提高了千粒重与穗粒数,且减量施肥20%产量差异不显著。综合考虑产量、肥料投入与环境压力,豫北和豫中地区夏玉米推荐施用海藻酸复合肥600 kg/hm2。

| Abstract: | The study aims to confirm the yield-increasing effect of alginic acid compound fertilizer of summer maize. Taking'Xundan 29'as the material, we conducted a field experiment by using mathematical statistics and comparison analysis method, to study the effect of alginic acid coated blend bulk fertilizer, average nutrients common blend bulk fertilizer, alginic acid coated compound fertilizer and average nutrients common compound fertilizer on yield, aboveground biomass, nutrient accumulation, SPAD of summer maize in Hebi and Xuchang. The results showed that the yield of summer maize increased significantly by 8.80%-15.41% and 21.21%-35.85%with the application of fertilizer in Hebi and Xuchang, respectively. Compared with average nutrients common blend bulk fertilizer, the alginic acid coated blend bulk fertilizer increased yield by 5.70%and 5.22%, respectively. Compared with average nutrients common compound fertilizer application, the yield under the application of alginic acid coated compound fertilizer increased significantly by 5.98%and 13.37%, respectively. Applying alginic acid compound fertilizer could improve chlorophyll content, 1000-grain weight, grain number of summer maize and promote nitrogen, phosphorus and potassium nutrient accumulation. The accumulation of nitrogen, phosphorus and potassium increased by 3.76%-17.03%, 6.29%-27.14% and 3.70%-9.33%respectively. When fertilizer application was reduced by 20%, the difference on yield was not significant. Considering the summer maize yield, fertilizer inputs and environmental pressure, the applicationof alginic acid compound fertilization 600 kg/hm2 is recommended in north and central Henan. |
