吉木乃县2011年大面积推广小麦滴灌栽培,不仅产量提高明显,而且取得良好经济效益。一、播前准备1.品种选择可选择新春10号、新春11号、新春29号等品种。2.产量结构667米2基本苗35万～40万株,667米2收获穗数38万～40万穗,单穗重1.2克,千粒重45克以上,667米2产量450千克以上。3.地块选择选择中等以上土壤肥力、含盐碱量小的条田。4.供肥标准根据当前土壤养分状况,中等以上土壤肥力(碱解氮46.8毫克/千克﹑速效磷21.7毫克/千克、速效钾282.6毫克/千克)条件下,667米2产量450～500千克,全生育期最佳施肥总量为:纯氮17.0～18.0千克、纯磷6.5千克、纯钾3.0千克,折总标肥135～140个,氮、磷、钾纯肥比例1∶0.38∶0.18。
Jimu County in 2011 to promote large-scale wheat drip cultivation, not only significantly increased production, but also achieved good economic returns. A preparation before sowing 1. Selection of varieties Choose New Year 10, New Year 11, New Year 29 and other varieties. 2. The yield structure of 667 m 2 basic seedlings 350,000 ~ 400,000, 667 m 2 harvest spike 380,000 to 400,000 spike, single panicle weight 1.2 grams, more than 45 grams of grain weight, 667 m 2 yield of 450 kg or more. 3. The choice of land plots to choose more than medium-sized soil fertility, low salinity fields. 4. Fertilizer standards According to the current soil nutrient status, moderate soil fertility (46.8 mg / kg of available nitrogen, 21.7 mg / kg of available phosphorus and 282.6 mg / kg of available potassium), the yield of 667 m 2 was 450-500 kg, The best total fertilization during the whole growth period was: 17.0-18.0 kg of pure nitrogen, 6.5 kg of pure phosphorus, 3.0 kg of pure potassium and 135-140 of total standard fertilizer, and the proportion of pure nitrogen, phosphorus and potassium was 1: 0.38: 0.18.
