叶面氮肥对色素型万寿菊营养生长的影响OA
Effects of Foliar Nitrogen Fertilizer on Nutritional Growth of Pigmented Marigold
为优化色素型万寿菊叶面氮肥施肥方法,提高施用效率,采用叶面氮肥种类、喷施浓度和喷施频率3因素3水平L9(33)正交试验设计,比较色素型万寿菊营养生长状况,筛选适宜的叶面氮肥施用方案.结果表明,与清水喷施处理相比,叶面菌肥、氮肥喷施各处理均显著促进了色素型万寿菊营养生长期株高的生长.叶面氮肥种类、喷施浓度和喷施频率3因素对色素型万寿菊营养生长影响效应由大到小依次为氮肥种类＞喷施频率＞喷施浓度.筛选出的促进色素型万寿菊营养生长效果较好的叶面氮肥施用方案为每7 d叶面喷施1次0.50‰碳酸氢铵溶液.
In order to optimize the foliar nitrogen fertilizer application method of pigment type marigold and improve the application efficiency,the L9(33)orthogonal test design with three factors and three levels of foliar nitrogen fertilizer type,spraying concentration and spraying frequency were used to compare the nutritional growth of pigmented marigold and screen the suitable foliar nitrogen fertilizer application scheme.The results showed that compared with water spraying treatment,foliar bacterial fertilizer and nitrogen fertilizer spraying significantly promoted the growth of plant height of pigmented marigold in vegetative growth period.The effect of 3 factors on the nutritional growth of pigmented marigold was as follows:nitrogen fertilizer type＞spraying frequency＞spraying concentration.The foliar nitrogen fertilizer application scheme with better effect on promoting the nutritional growth of pigment type marigold was spraying 0.50‰ ammonium bicarbonate solution on the leaves every 7 days.
