叶面氮肥对色素型万寿菊营养生长的影响
Effects of Foliar Nitrogen Fertilizer on Nutritional Growth of Pigmented Marigold
摘要
Abstract
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.关键词
