摘要
[目的]研究水肥一体化技术在澳洲坚果生产上的应用效果,总结出一套适合澳洲坚果水肥一体化技术.[方法]试验设置6个处理,分别为环形滴灌高质肥、环形滴灌有机肥、环形滴灌普通化肥、定点滴灌普通化肥、喷灌普通化肥和常规施肥,测定不同处理对果实产量、落果、大小的影响.[结果]6种处理中,效果最好的是环形滴灌有机肥,产量为5969.7 kg/hm2,增产15.96%,落果减少率可达24.11%,经济效益可达9.55万元/hm2,成本1.26万元/hm2,对比常规施肥,利润增加1.78万元/hm2.[结论]把水肥一体化技术——环形滴灌有机肥应用于澳洲坚果上,可以有效地提高产量,改善果实大小,减少落果率,有利于增产增收.
Abstract
[Objective] The objective was to explore the effects of fertigation on Macadamia integrifolia production, sum up a suitable fertiga-tion technology for Macadamia integrifolia..[ Method] Set six different treatments:annular drip irrigation high quality fertilizer,annular drip or-ganic fertilizer, annular drip common fertilizer, fixed-point drip common fertilizer, sprinkling irrigation common fertilizer and conventional fer-tilization .Effect of different treatments on yield ,fruit drop and size was researched.[ Result] Among six treatments, annular drip organic fer-tilizer was the best , which yield was 5969.7 kg/hm2 ,increased by 15.96%, fruit drop was decreased by 24.11%.The economic benefit reached 9.55 ×104 yuan/hm2 and the cost was 1.26 ×104 yuan/hm2 .In contrast to the conventional fertilization, profits increased by 17800 yuan /hm2.[Conclusion] Fertigation technology-ring drip organic fertilizer for Macadamia integrifolia can effectively improve the yield and fruit size, reduce the fruit drop rate and increase production and economic benefit.
