摘要
为了在次适宜种植区的砂土地上栽培强筋小麦提高产量并改善品质,采用常规田间试验及统计分析方法并结合品质测试进行研究.结果表明,在砂粒含量632g/kg、粉砂粒含量293g/kg、黏粒含量75g/kg的豫东平原砂土地上种植强筋小麦,在施氮(N)总量均为300kg/hm2的试验条件下,采取"底追均衡供应"(底、追肥量各占50%)、"追肥两次分配"(拔节期追施30%、孕穗期追施20%),即"532"施肥模式,强筋小麦产量和品质因素更为协调,可作为豫东砂土区现行生产、生态及技术条件下,种植强筋小麦实现高产优质目标,氮肥合理分配和运筹的主要技术措施来运用.
In order to increase production and improve the quality of strong gluten wheat cultivation times the sand on the ground suitable for planting area, the use of conventional field trials and statistical analysis methods and research combined with quality test. The results show that, the sand content of 632 g / kg, silt content of 293 g / kg, the clay content of 75 g / kg of Eastern Henan Plain sand ground planting wheat, Nitrogen fertilizer （N） total of 300 kg/hm2 test conditions, to take the end of chase balanced supply （bottom, accounting for 50 %） of the amount of fertilizer the dressing twice allocation （30 % of the jointing stage hooting stage 20 %）, the ＂532＂ fertilization mode wheat Yield and quality factors more coordinated, as the the Yudong sand area current production, ecological and technical conditions, cultivation of strong gluten wheat yield and quality the goal, nitrogen reasonable allocation and logistics major technical measures to use.
