摘要 为提高氮肥利用率,提高甜菜产质量,推广缓释肥料的使用,采用‘HI003’为试材,研究缓释肥料和普通肥料对甜菜叶绿素含量、干物质重、蔗糖含量、块根产量和含糖率、土壤脲酶活性的影响。结果表明,8月5日样品中,缓释肥料处理比普通肥料处理叶绿素含量提高12.22%;9月5日样品中,单纯缓释肥料处理比普通肥料处理叶绿素含量提高9.72%。在生育期前期,普通肥料处理的干物质重高于使用缓释肥料的处理;在生育后期,使用缓释肥料的处理的干物质重高于普通肥料处理。缓释肥料和普通肥料对甜菜叶片和块根蔗糖含量影响不显著。缓释肥的施用降低了甜菜生育期土壤脲酶活性。缓释肥料处理比普通肥料处理提高了甜菜块根产量和含糖量,3种处理中,普通肥料:缓释肥料=1:1,产糖量最高,效果最好。初步试验表明,缓释肥料对于甜菜的增产效果明显,有必要进一步对缓释肥料类型进行筛选,减少肥料使用量,减少施肥造成的环境污染。 To increase the use efficiency of nitrogen fertilizer,improve yield and quality of sugar beet and popularize the slow-release fertilizer application,we studied the effects of slow-release fertilizer and common fertilizer on the contents of chlorophyll,dry weight,sucrose,the yield and quality of sugar beet,and the soil urease activity by adopting‘HI003’as the experimental material.The results showed that:the chlorophyll content of slow release fertilizer treatment was 12.22%higher than that of common fertilizer on August 5 and9.72%higher than that of common fertilizer on September 5,respectively;in the early growth stage,the dry weight of slow-release fertilizer treatment was lower than that of common fertilizer,however,the dry weight of slow-release fertilizer treatment was higher than that of common fertilizer in the late growth stage;the effects of slow release fertilizer and common fertilizer on the sucrose content in leaves and roots of sugar beet was not significant;the slow release fertilizer decreased soil urease activity in sugar beet growing stage;compared with common fertilizer,the slow-release fertilizer treatment increased the yield of root and sugar content;among the three treatments,slow-release fertilizer to common fertilizer of 1:1 achieved the best performance and its sugar yield was the highest.The experiment shows that the slow-release fertilizer contributes to the yield of sugar beet,so it is necessary to screen suitable slow-release fertilizer to cut down the fertilizer application amount,thus to reduce the environmental pollution caused by fertilization.
