通过近年来冬小麦每公顷产量超 90 0 0 kg的综合配套技术体系研究得出 :施足基肥、培肥地力是冬小麦每公顷产量超 90 0 0 kg的关键 ;因地制宜选用高产良种和合理的栽培技术是实现每公顷产量超 90 0 0 kg的基本保证。初步认为 ,在目前生产条件下 ,选用成穗率高的多穗型品种创每公顷 90 0 0kg以上产量较种植大穗型品种更为稳妥 ;基本苗多穗型品种以 12 0～ 180万 /hm2 ,大穗型品种以 2 10～2 4 0万 /hm2为宜 ;总施肥量以每公顷施纯氮 2 70 kg、P2 O5187.5kg、K2 O2 10 kg为宜 ,N∶P∶ K的施肥配比为 1∶ 0 .7∶ 0 .8;重施拔节肥 ,补施挑旗肥。全生育期浇四次水 ;生育后期以延长功能叶的有效光合时间、提高光合能力、增加穗重为主攻目标。
According to the comprehensive technical system of wheat yield over 900 kg per hectare in recent years, it is concluded that the application of sufficient base fertilizer and soil fertility is the key to the yield of wheat over 90 0 kg per hectare. The selection of high-yielding varieties and reasonable cultivation techniques This is the basic guarantee for achieving a yield of 900 kg per hectare. It is preliminarily believed that under the current production conditions, the yield of more than 90kg per hectare is more reliable than that of the large panicle type when the panicles with high panicle rate are selected. The basic panicle type with more panicles is 120 ~ 1.8 million / hm2, and large spike varieties were 210 ~ 240,000 / hm2. The total fertilization amount was 2 70 kg pure nitrogen per hectare, P2 0 5187.5 kg, K2 O2 10 kg, N: P: K Fertilization ratio of 1: 0 .7: 0 .8; The whole growth period of watering four times; late growth period to extend the effective leaf photosynthetic time, increase photosynthetic capacity, increase ear weight as the main target.
