摘要: 针对生产中存在的问题,结合多年的试验、示范结果,优化栽培技术研究及高产创建应用,探讨了玉米高产栽培中的关键因子——氮、磷、钾肥、密度与产量的回归关系。研究结果表明:‘邯玉66’大面积高产群体产量结构指标为:收获株数63000~67500株/hm 2 ;每穗450~600粒,千粒重325~345g,穗行数14~18行,行粒数33~35粒,单穗粒重160~210 g,穗长17~22 cm。‘邯玉’种植密度及N、P、K优化栽培技术方案:产量9750~10500 kg/hm 2 ,优质有机肥60-75m3/hm2,SN 115-150kg/hm2,SP2O5 300-375kg/hm2,SK2O 225-300kg/hm2。在玉米品种邯玉66特征特性、生产的气候和土壤条件、播种技术、施肥技术、田间管理、病虫害防治、收获等方面进行了规定,制定了‘邯玉66’高产高效栽培技术规程,为玉米“高投入、低产出”向“高产、高效”的转变提供理论依据和技术支撑。

Abstract: In view of the problems existing in production, combined with many years of experiment and demonstration results, the cultivation technology and high yield creation application are optimized. The regression relationship between N,P,K, density and yield of Maize in high yield cultivation was discussed.The results showed that the high-yield group yield structure index of "Han Yu 66" was 63000~67500 plant /hm 2, 450~600 grains per panicle, grain weight of 325~345g, 14~18 row number per spike, 33~35 grain number of row grain, 160~210 g of single spike grain weight, 17~22 cm of ear length. "HanYu 66 2, high quality organic fertilizer 60-75m3/hm2, N 115-150kg/hm2, P2O5 300-375kg/hm2, K2O 225-300kg/hm2. We stipulated the characteristics of Han Yu 66, the climate and soil conditions of production, the planting techniques, the fertilization technology, the field management, the pest control and the harvest time. We have made the high and efficient cultivation technical regulations of the "Hanyu 66", which provided the theoretical basis and technical support of transformation of "high input and low yield" to "high yield and high efficiency".
