弱筋小麦新品种绵阳30号优质高产栽培技术研究

Study on the Cultivation Measures of the Weak-gluten and High-Yield Wheat Variety Mianyang 30

绵阳30号是优良的弱筋小麦品种。为了充分发挥其高产、优质潜力,为大面积推广应用提供参考依据,进行了两年的栽培技术研究。结果表明,氮肥是影响绵阳30号产量和品质的主要因素。绵阳30号的优质高产配套栽培技术模式为:播种期为10月20日至11月1日,密度为195.6万～205.8万株/hm2基本苗,纯氮用量81.9～88.2kg/hm2,P2O5用量61.5～67.5kg/hm2,K2O用量151.5～164.25kg/hm2,氮肥追肥时期以拔节期为宜(氮肥基追比为7∶3)。

In order to provide reference for the farm production, the cultivation measures of the (weak-gluten) and high-yield wheat variety Mianyang 30 were studied during the period of 2002～2004. The (results) showed that nitrogen was a main factor that determined the quality and yield. The suitable (sowing) dates were from 20th Oct. to 1st Nov., the proper ranges of N, P_2O_5 and K_2O (applied) and basic seedling should be 81.9～88.2 N kg/hm^2, 61.5～67.5 P_2O_5 kg/hm^2, 151.5～164.25 K_2O kg/hm^2 and 195.6×10~4 ～ 205.8×10~4 plants/hm^2 in Mianyang, and the suitable stage of topdressing nitrogen was jointing stage when the ratio of basic (application) to topdressing of nitrogen was 7∶3.
