不同基肥垫施对黎蒴栲容器苗的影响

摘要

以桐麸、碳化木糠和钙镁磷肥作基肥进行黎蒴栲( Castanopsis fissa)容器育苗试验，研究苗木主要生长指标在垫施不同基肥下的变化，探索适宜培育黎蒴栲容器苗垫施基肥的种类、施用水平，结果表明：不同垫施基肥处理对黎蒴栲容器苗生长指标具有明显影响；垫施基肥的处理苗木生长均比对照好；垫施有机肥苗木生长好于垫施无机肥；基肥垫施比把基肥拌入基质好。黎蒴栲容器苗垫施基肥800 g/m2的效果最佳。%In order to detect the appropriate basal fertilizers and fertilizing level for the growth of Castan-opsis fissa container seedlings, container seeding experiment of C. fissa with different basal fertilizers (i. e. , tung bran, carbonized wood chaff and calcium magnesium phosphate) was conducted, and the change of growth indexes of seedlings treated with different basal fertilizers was studied. The results showed that different basal fertilization had obvious effect on the growth indexes of C. fissa container seed-lings, and the container seedlings with basal fertilizers grew better than those with no basal fertilizer. The seedlings using organic matter as basal fertilizer grew better than those using inorganic matter. The seed-lings treated by putting the basal fertilizers under nutrition bag grew better than those treated by mixing the basal fertilizers with yellow soil. Putting basal fertilizers under nutrition bag for 800 g/m2 was the bet-ter treatment for C. fissa container seedling.
