盐化潮土甜菜新品种HI0099提糖增效栽培技术研究

Study on the Cultivation Technology of a New Variety of Salinized Sugar Bbeet HI0099 With Sugar Extraction and Efficiency

为了促进河西走廊甜菜产业可持续发展.在甘肃省张掖市甘州区盐化潮土上,进行了盐化潮土甜菜新品种HI0099提糖增效栽培技术研究.结果表明:随着甜菜种植密度的递减,根体长度、根直径和单株根重在递增,块根产量、产值、纯利润和投资效率先增后降,最佳种植密度为8.33万株/hm2.随着播种期的推迟,甜菜块根产量、产值、纯利润和投资效率先增后降,最佳播种期为4月13日.在盐化潮土上秸秆畜禽粪便生态肥替代传统化肥改土增产效果明显,在纯氮磷钾投入量相等的条件下,施用秸秆畜禽粪便生态肥与传统化肥比较,土壤容重和pH值降低14.49和7.69%,总孔隙、团聚体、饱和蓄水量、CEC和有机质增加17.52%、11.72%、17.52%、27.49%和10.60%;甜菜根体长度、根直径、单株根重、含糖率和产糖量增加7.52%、6.66%、9.32%、7.07%和18.40%;块根产量、产值、纯利润和投资效率增加5.36%、8.58%、15.63%和22.30%.

In order to promote the sustainable development of beet industry in hexi corridor.A new variety of sugar beet,HI0099,was studied on salinized tidal-soil in ganzhou district,zhangye city,gansu province.The results showed that with the decrease of planting density of sugar beet,the height,weight,root length,root diameter and root weight per plant increased,the yield,output value,net profit and investment efficiency of root tuber increased first and then decreased,and the optimal planting density was 83300 plants/hm2.With the delay of sowing date,the yield,output value,net profit and investment efficiency of beet root increased first and then decreased.The best sowing date was April 13.In the ecology of animal manure in fluvo-agvic soil salinization straw alternatives to traditional fertilizer content increased yield effect is obvious,under the condition of pure mass equal NPK,poultry and animal feces ecological fertilizer applying straw compared with traditional chemical fertilizers,reduce soil bulk density and pH 14.49 and 7.69%,total porosity,aggregate,saturated storage capacity,CEC and organic matter increased by 17.52%,11.72%,17.52%,27.49%and 10.60%;The length of beetroot body,root diameter,root weight per plant,sugar content and sugar yield increased by 7.52%,6.66%,9.32%,7.07%and 18.40%.Root yield,output value,net profit and investment efficiency increased by 5.36%,8.58%,15.63%and 22.30%.
