促进闽楠幼苗健壮培育的施肥研究

闽楠幼苗;健壮培育;施肥
摘  要：
研究了 N-P-K肥料对闽楠苗木生长和形态属性的影响.结果发现:适度的N、P和K比例的联合施用可以显著提高闽楠的苗高、地径直径和高度-直径比(HD)等形态属性,同时增加了根、茎、叶和整株植物的干物质积累.在容器闽楠的生产中,应根据研究结果,采用适度的N、P和K肥料比例,以获得最佳的形态属性和生物量积累.为此建议:将N、P和K的最佳比例控制在1∶0.20∶0.43~1∶0.65∶0.75.为了最大化闽楠苗木的生长和生物量积累,可将N的施用量控制在0.439g/株,P2O5的施用量控制在0.123g/株,K2O的施用量控制在0.295g/株.在实际生产中,应密切监测植物的生长情况,并根据土壤和植物的养分需求进行施肥管理,以确保植物获得适度的养分供应,避免过度施肥和养分浓度达到毒性范围.

摘  要：
This paper investigates the effect of N-P-K fertilizer on the growth and morphological proper-ties of Phoebe bournei(Hemsl.)seedlings.Research has found that a moderate combination of N,P,and K ratios can significantly improve the morphological properties of Phioebe bournei(Hemsl.),such as seedling height,ground diameter,and height diameter ratio(HD),while also increase the dry matter ac-cumulation of roots,stems,leaves,and the entire plant.The analysis of Phoebe bournei(Hemsl.)Qual-ity Index(QI)shows that the combination of moderate N,P,and K fertilizers is the most favorable nu-trient ratio for Phoebe bournei(Hemsl.)seedling cultivation.In the production of container Phoebe bour-nei(Hemsl.),an appropriate proportion of N,P,and K fertilizers should be used based on research re-sults to obtain the best morphological properties and biomass accumulation.It is recommended to control the optimal ratio of N,P,and K between 1∶0.20∶0.43 and 1∶0.65∶0.75.In order to maximize the growth and biomass accumulation of Phoebe bournei(Hemsl.)seedlings,the application rate of N can be controlled at 0.439g/plant;the application rate of P2O5 can be controlled at 0.123g/plant,and the appli-cation rate of K2 O can be controlled at 0.295g/plant.In actual production,the growth of plants should be closely monitored and fertilization management should be carried out based on the nutrient needs of the soil and plants to ensure that plants receive moderate nutrient supply and avoid excessive fertilization and nutrient concentration reaching the toxic range.
