摘要
当前农业生产中存在农民单一肥料施用或单质肥料随意混施问题,导致土壤养分比例失调,农作物产量不高和品质差,经济效益低。为了改善土壤结构,营造良好的植物生长环境,提高作物产量,达到经济合理施肥、降低生产成本的目的,以冬小麦品种160为试材,进行了冬小麦施用配方肥、等量氮磷混合肥、单质氮肥和单质磷肥的肥效比较试验。结果表明:施用配方肥能使冬小麦三叶期、分蘖期、拔节期、抽穗期的植株鲜重、干重、分蘖数和成穗率显著增加;配方肥处理的冬小麦产量最高为7 056 kg/hm2,较对照增产90.14%,增产效果显著。说明养分含量相同情况下,施用由厂家生产的成品配方肥比单一肥料施肥和单质肥料混施能促进冬小麦各生育期生长指标提高,产量增加,经济效益明显提高。
In current agriculture production,the problems of single-element fertilizer appliction and single fertilizer mixed freely caused the disproportion of soil nutrient,low crop yield,poor quality and low economic efficiency.To improve soil structure,build up plant growth environment,raise crop yield,achieve economic and reasonable fertilization,and reduce production costs,the efficiency of formula fertilizer and single fertilizer on winter wheat was comparsed.The results showed that the formula fertilizer could significantly increase the plant fresh weight,dry weight,tiller number and spike rate at three leaves stage,tillering stage,jointing stage and heading stage.The highest yield was 7 056 kg/hm2 with the formula fertilizer,which increased by 90.14%.The formula fertilizer could improve the growth index,and increase the yield and economic benefit.
