在山西临汾等地针对气候变暖开展了系列试验,研究提出了旱地小麦“一晚两增一缩一控”高产抗逆关键技术,其关键技术是“一晚”即推迟播种期,较传统播种期(9月24日～9月26日)推迟7～8天,即10月1日～10月3日;“两增”即增加播种密度和增加施肥量,播种密度由23万/亩提高到27万/亩,纯氮由8.5kg/亩提高到13kg/亩,P2O5用肥量由4.8kg/亩提高到7.5kg/亩;“一缩”即缩小播种行距,播种行距由现行的18～20cm缩小为15cm;“一控”即遇多雨年型,在拔节期喷施多效唑,控制倒伏。
In Linfen, Shanxi and other places to carry out a series of experiments on climate warming, the study proposed dryland wheat “one night and two by one by one control ” high yield stress key technology, the key technology is One night Period, than the traditional sowing period (September 24 ~ September 26) postponed 7 to 8 days, that is, October 1 to October 3; “two increases ” that is, increase the planting density and increase the amount of fertilizer, sowing The density increased from 230000 / mu to 270000 / mu, the pure nitrogen increased from 8.5kg / mu to 13kg / mu, the P2O5 fertilizer increased from 4.8kg / mu to 7.5kg / mu; Sowing row spacing, sowing row spacing from the current 18 ~ 20cm reduced to 15cm; “a control ” that is rainy years type, spraying paclobutrazol at jointing stage, control lodging.
