摘要
近年来随着樱桃种植业的发展,采用滴灌施肥的方式十分普遍,但肥料的选择与应用是关键。针对京郊樱桃养分吸收规律、果园土壤养分状况和有机肥施用习惯提出京郊樱桃适宜NPK水溶肥配方及施肥方案,即一年生的樱桃,定植肥施有机肥7 500kg.hm-2,NPK(28-17-0)复合肥45kg.hm-2,4月中旬追施NPK(19-31-0+TE)水溶肥75kg.hm-2;二～六年生樱桃秋季基肥施有机肥30 000kg.hm-2左右,NPK(26-4-15)复合肥225～300kg.hm-2,3月中旬分次追施NPK(18-4-28+TE)水溶肥50～150kg.hm-2;6月初分次追施NPK(24-5-21+TE)水溶肥50～75kg.hm-2;七年生以上的樱桃秋季施有机肥45 000～60 000kg.hm-2,NPK(24-4-19)复合肥225～375kg.hm-2,3月中旬分次追施NPK(14-6-30+TE)水溶肥225～375kg.hm-2,采果后追施NPK(20-6-25+TE)水溶肥300～335kg.hm-2,为优质高产的樱桃生长提供保障。
Along with the development of cultivated cherry industry,the fertigation has been widely used in recent years. Therefore,fertilizer selection and application are the key factors that affect fertigation. The appropriate NPK formula of water-soluble fertilizer and fertilizing plan were proposed, according to the law of absorption of cherries, nutrient status of orchard soil and manure application： For one-year-old cherry, 7 500 kg. hm2 manure and 45 kg. hm2 NPK （28-17-0 ） compound fertilizer were applied when planted ; 75 kg. hm-2 NPK （ 19-31-0 ＋ TE）water-soluble fertilizer was applied in the middle of April. For 2-6-year-old cherry,about 30 000 kg-hm2 manure and 225 - 300 kg. hm-z NPK （26-4-15） compound fertilizer were applied as base fertilizer; 50 - 150 kg. hm 2 NPK（ 18-4-28 ＋ TE） water-soluble fertilizer was applied in several times in the middle of March; 50 - 75 kg. hm-1 NPK （24-5-21＋TE） water-soluble fertilizer was applied in several times at the beginning of June. For seven-year-old or more,45 000-60 000 kg.hm-2 manure and 225-375 kg.hm-2 NPK（24-4-19）compound fertilizer were applied as base fertilizer;225-375 kg.hrn-2 NPK（14-6-30＋TE）water-soluble fertilizer was applied in several times in the middle of March; 300 - 335 kg. hrn-2 NPK（20-6-25 ＋ TE） water-soluble fertilizer was applied after harvest. Those provided guar- antee for high quality and high yield of cherry.
