摘要
以15年生枸杞为试材,采用单因素随机区组设计,设3个水平施地佳施用量,即10mL/棵追施1次,20mL/棵分2次施,20mL/棵追施1次,以不施为对照,研究施地佳对盐碱地枸杞生长状况及产量的影响。在枸杞初展叶初期至夏果末期定期取土壤样、植株样,对土壤pH值、全盐、全氮、速效氮、全磷、速效磷、植株生长期生长状况进行测定,并对采摘果的主要营养成分及产量进行测定。结果表明:施地佳有明显降低土壤pH值和含盐量的作用,对枸杞甜菜碱、总糖量、多糖含量影响不大,但施用施地佳后黄酮含量有所增加,枸杞产量明显提高。建议施用量为20mL/棵,结合灌水分2次施入。
Taking 15-year-old wolfberry as materials,Shidijia were divided into three levels（10mL/plant with topdressing once,20mL/plant with twice,20mL/plant with topdressing once,which compared with no applying anything）.The influence of Shidijia on the growth conditions and yield of wolfberry in saline-alkali soil was studied.Other factors such as water and fertilizer controlled as normal management.Main indicators such as soil pH value,organic matter,total amount of salt,total nitrogen,available nitrogen,total phosphorus,available phosphorus,as well as yield and quality were determined during wolfberry growing period.The results showed that Shidijia had good effect on reducing soil pH value and salinity,and had no obvious effect on regulating nitrogen in terms of the regulation of nitrogen and phosphorus and had little impact on wolfberry betaine and total polysaccharide,flavonoid content,however increased,yields increased too.In a word,the level of applying rate with 20mL/plant,combined with irrigation applied in two times were commended.
