不同施肥水平对温室栓皮栎幼苗生长的影响

The Effect of Different Fertilization Levels on the Growth of Quercus Variabilis Seedlings in Greenhouse

笔者在山西省中条山国有林管理局林木良种繁育实验基地,开展了不同施肥时间与施肥量对温室栓皮栎幼苗生长影响的研究。结果表明,施肥对温室栓皮栎苗木生长指标、生物量有显著影响。总体来看,各施肥处理栓皮栎苗木的苗高、地径、各器官生物量均大于CK。其中,施肥4 min对苗木生长影响最大,2 min施肥量不足,6 min水肥流失严重。说明利用温室喷灌系统穴盘培育栓皮栎幼苗,时间控制在4 min最好,单株施肥量0.18 g最佳。

In the experimental base for breeding of forest tree varieties in national forest administration bureau of Zhongtiao mountain in Shanxi province,a study on the effects of different fertilization times and amounts on the growth of Quercus variabilis seedlings in greenhouses was conducted.The results showed that fertilization had a significant impact on the growth indicators and biomass of Quercus variabilis seedlings in greenhouses.Overall,the seedling height,ground diameter and organ biomass of Quercus variabilis seedlings treated with various fertilizers were higher than those of the CK.Among them,fertilization for 4 minutes had the greatest impact on seedling growth,insufficient fertilization at 2 minutes and severe water and fertilizer loss at 6 minutes.When using a greenhouse sprinkler irrigation system to cultivate Quercus variabilis seedlings,it was best to control the time at 4 minutes and apply 0.18g of fertilizer per plant.
