叶面施肥给杉木苗期生长带来的影响探究

Effect Of Foliar Fertilization On The Growth Of Cunninghamia Lanceolata Seedlings

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
