1997- 1998年, 在四川三个主要生态麦区就综合性农艺措施对小麦品种“川麦28”产量的影响进行多因素综合试验,结果表明: (1) 栽培因素对产量的影响程度, 因不同生态环境而异。盆西平原麦区播期〉N肥〉密度〉P肥〉K肥; 盆中浅丘麦区N肥〉播期〉P肥〉K肥〉密度; 盆东南麦区P肥〉N肥〉播期〉密度〉K肥。(2) 某一栽培因素对小麦产量的影响, 因生态区域和其他栽培因素所处水平不同, 其作用规律与作用大小也就不同。因此因地制宜, 制定科学的栽培措施, 对发挥品种潜力, 节省投资, 实现高产具有重要意义。
In 1997-1998, a comprehensive multivariate test was conducted on the effects of comprehensive agronomic practices on the yield of wheat cultivar “Chuanmai 28” in three major ecologic areas in Sichuan province. The results showed that: (1) Different ecological environment varies. The sowing date of wheat in the basin of western Guangxi> N fertilizer> density> P fertilizer> K fertilizer; N fertilizer in shallow middle mound area> sowing date> P fertilizer> K fertilizer> > Density> K fertilizer. (2) The effect of a cultivation factor on the yield of wheat is different because of the different levels of ecological factors and other cultivation factors. Therefore, according to local conditions, the development of scientific cultivation measures to play a variety of potential, save investment and achieve high yield is of great significance.
