不同配比追肥对设施种植草珊瑚生长的影响

Effects of Different Fertilizer Ratio of Topdressing on the Growth of Sarcandra Glabra Fields Facilities

在草珊瑚田间设施种植大棚内,采用氯化钾复合肥、人畜尿液(沤熟)、浓缩有机水溶肥3种肥料设计3个不同配比对草珊瑚进行了灌根追肥:处理A-氯化钾复合肥兑水配制成1%浓度+人畜尿液(沤熟)15%浓度+浓缩有机水溶肥0.5%浓度;处理B-氯化钾复合肥兑水配制成1%浓度+人畜尿液(沤熟)15%浓度;处理C-氯化钾复合肥兑水配制成1%浓度+浓缩有机水溶肥0.5%浓度,并设置不施肥CK(对照),比较了不同处理4年生草珊瑚的生长效果。结果表明:4种处理以处理A草珊瑚的生长效果最好,平均高、平均地径、平均分枝数、平均冠幅、≥10 cm长Ⅰ级侧根平均条数、侧根平均根幅分别达59.2 cm、0.55 cm、12.9条、55.6 cm、28.4条、34.9 cm。

In the greenhouse of Sarcandra Glabra field facilities,three kinds of fertilizers,potassium chloride compound fertilizer,human and animal urine(retting)and concentrated organic water-soluble fertilizer,were used to design three different ratios of root irrigation and topdressing for Sarcandra Glabra:treatment of A-potassium chloride compound fertilizer with water prepared 1%concentration+Human and animal urine(retting ripe)15%concentration+concentrated organic water-soluble fertilizer 0.5%concentration,treatment of B-potassium chloride compound fertilizer with water prepared 1%concentration+human and animal urine(retting ripe)15%concentration and treatment of C-potassium chloride compound fertilizer with water prepared 1%concentration+concentrated organic water-soluble fertilizer 0.5%concentration.No fertilizer CK(control)was set to compare the growth effects of 4 year old Sarcandra Glabra under different treatments.The results showed that among the four treatments,the growth effect of Sarcandra Glabra A was the best;The average height,average ground diameter,average branch number,average crown width,more than 10 cm lengthⅠgrade lateral root average number and the average root width were 59.2cm,0.55cm,12.9,55.6cm,28.4,34.9cm,respectively.
