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/hm2;每穗450~600粒,千粒重325~345 g,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/hm2,优质有机肥60~75 m3/hm2,N 115~150 kg/hm2,P2O5300~375 kg/hm2,K2O 225~300 kg/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。
In view of the problems existing in production,combined with years of experiment and demonstration results,the cultivation technology and high yield creation application were optimized,and the regression relationship between N,P,K,density and yield of maize in high yield cultivation was studied.The results showed that the high-yield group yield structure index of‘Hanyu 66’was 63000 to 67500 plant per hectare,450-600 grains per ear,the 1000-grain weight was 325-345 g,the average number of rows number per ear was 14-18,the grains number per row was 33-35,the single spike grain weight was 160-210 g,the spike length was 17-22 cm.‘Hanyu 66’planting density and N,K optimized cultivation techniques was as follows:yield 9750-10500 kg/hm2,high quality organic fertilizer 60-75 m3/hm2,N 115-150 kg/hm2,P2O5 300-375 kg/hm2,K2O 225-300 kg/hm2.We stipulated the characteristics of‘Hanyu 66’,the climate and soil condition of production,the planting techniques,the fertilization technology,the field management,the pest control and the harvest time.We made the high and efficient cultivation technical regulations of‘Hanyu 66’,which could provide technical support for the transformation from'high input and low yield'to'high yield and high efficiency'.
