| 摘要: |
| 2004年1~5月在广西林业科学研究院试验场,选用L9(34)正交进行大叶栎(Castanopsis fissa)试验,考察营养土配方(林下表土,林下表土+草皮灰+农家肥按100:30:20比例混合),林下表土+农家肥+磷肥按100:20:3比例混合)、追肥次数(不追肥,每月追肥1次,每月追肥2次)和营养杯规格(直径×高度:14cm×12 cm,12 cm×18 cm,10 cm×16 cm),对大叶栎苗木的株高、地径及根系生长的影响,挑选出最佳的大叶栎营养杯育苗组合。结果表明:影响大叶栎苗木生长的主要因素是营养土配方;使用混合比为100:30:20的林下表土+草皮灰+农家肥作营养土,规格为12 cm×18 cm(直径×高度)的营养杯进行育苗,育苗期不追肥,是本次试验的最佳组合。 |

| Abstract: |
| From the January to the May in 2004,we selected the L9(34) orthogonal to carry on Castanopsis fissa experiment inspection,in the field test of the Guangxi forestry research institute,estabilished three processing,each processing three levels,including nutritive soil composition[surface;surface soils +turf ash+farmyard manure(the ratio is 100:30:20);surface soils+farmyard manure +Phosphate fertilizer(the ratio is 100:20:3)],topdressing number of times(not topdressing,each month of topdressing 1,each month of topdressing 2),and nutrition cup specification(diameter×altitude:14cm×12cm,12cm×18cm,10cm×16cm).At the meanwhile,influence growth which regarding nursery stock's high,diameter and the root system,chooses the best nutrition cup to grow seedlings the combination of Castanopsis fissa.The result indicated that the main factor affecting seedling growth is nutritive soil composition,and the best composition is to ues surface soils +turf ash +farmyard manure(the ratio is 100:30:20) as nutritive soil, to plant seedlings with nutritive cup of the diameter of 12 cm and the altitude of 18 cm,and not to dress fertilizers during the seedling cultivation. |
