Apple is a kind of high economic value fruit, occupying an important position in China’s fruit industry. However, apples need to consume large amount of water resources in the process of planting, which does not match the current situation of water shortage in China. In order to alleviate the shortage of water resources, the use of advanced water-saving irrigation technology in orchards is on the way.This paper summarizes some commonly used irrigation modes at present, so as to provide reference for better water-saving irrigation promotion in apple orchards.
桃起源于中国,迄今已有四千多年的栽培历史.1993年至今,我国桃的种植面积和产量均居世界第一.FAO统计数据显示,全球桃(含油桃、蟠桃,下同) 2020年种植面积227万hm2,产量3959万t.
为提高'红仁核桃'产量和品质,在正常施肥的前提下,作者在6月下旬和7月上旬进行喷施不同叶面肥试验,调查对树体生长、坚果产量和品质的影响,为叶面肥在'红仁核桃'生产上的科学使用提供依据.试验结果表明,喷施氨基酸+倍溶磷钾肥对促进树体生长、提高坚果产量和品质的作用最明显,可以在生产中推广.
该试验以'嘎拉'苹果为试材,开展几种杀菌剂对苹果斑点落叶病和褐斑病的防效试验.结果表明,67％唑醚·丙森锌SC 1000倍和1500倍液处理对苹果斑点落叶病的防效分别为89.46％和85.22％,对褐斑病的防效为96.50％和92.55％;25％吡唑醚菌酯SC 2000倍+43％戊唑醇SC 4000倍和25％吡唑醚菌酯SC 1500倍+43％戊唑醇SC 3000倍液处理对斑点落叶病的防效为81.07％和91.38％,对褐斑病的防效为84.97％和90.48％.均优于对照药剂百泰.试验说明67％唑醚·丙森锌SC,以及25％吡唑醚菌酯SC和富力库组合对苹果斑点落叶病和褐斑病具有良好的防治效果.
