摘要
目的:探究叶面施肥给杉木苗期生长带来的影响。方法:选取同品种杉木苗,随机分为两组,特多收组喷施1.000g/l^(-1);叶面肥组喷施0.167g/l^(-1)叶面肥,分析比较两组喷施效果。结果:3个月后,叶面肥处理组和特多收处理组同清水处理组相比较,杉木苗的高度、干重、Ⅰ级苗比例比较存在极显著差异,具备统计学意义(P<0.01);比较两组地径差异明显(P<0.05)。结论:特多收叶面肥处理后,杉木苗的苗高、地径、干重、Ⅰ级苗比例分别增长6.15%、5.41%、39.51%、7.34%,效果较喷施宝叶面肥明显较优。
To explore the effect of foliar fertilization on the growth of Cunninghamia lanceolata seedlings. Methods: Selecting the same varieties of Chinese fir seedlings which were randomly divided into two groups, group 1000g/1 - 1 received Trinidad and Tobago spraying foliar fertilizer group; 0. 167g/1 -1 spraying foliar fertilizer, spraying effect analysis and comparison of two groups. Results: After 3 months, the foliar fertilizer treatment group and treatment group with Trinidad and Tobago received water treatment group compared to Sugiki Nae' s height, dry weight, seedling grade proportion was significantly different, with statistical significance ( P 〈 O. O1 ) ; the diame- ter difference between the two groups ( P 〈 0.05 ). Conclusion : Trinidad and Tobago received foliar treatment, Sugiki Nae seedling height, ground diameter and dry weight, the proportion of first class seedling growth of 6. 15%, 5.41%, 39.51%, 7.34%, than the effect of jet grouting fertilizer Penshibao is better than others
