果树氨基酸液肥涂干技术

2017-08-10 08:25:42   

氨基酸液肥选择果树涂干最好选用动物性氨基酸原汁产品。用动物角蛋白为原料生产的螯合液,在常规可测的18种氨基酸之外,所含的其他氨基酸、多肽类有机活性物质比植物蛋白作原料的要高得多。

科学掌握喷涂时间杏园树干涂用氨基酸液肥补营养,从盛花期起每10~15天1次,共喷涂3次。而结果期较长的苹果、梨、枣等主要补充储藏营养,春季树液活动后至萌芽期、开花至幼果期和秋季枝梢停长(叶片木栓老化)后的3个时期,都是氨基酸液肥涂干的黄金期。果实生长中后期,可结合防治病虫害叶面喷用液肥,无需涂干,因涂后可使果实着色成熟推迟,有损无益。

改进喷涂技术喷涂时稀释倍数要因各类果树和液肥的不同,依实践结果相应调整,正常情况下3倍比较合适,提高浓度最好先做试验。春、秋季两次涂干自配稀释液时,可酌加少量氮素化肥及蜂蜜,充分搅匀溶解。原始刷涂功效慢,可改进为喷涂(用背负式喷雾器卸掉喷头旋片),不仅省力,而且喷液可进树皮缝内,效果好。中肥
