杉木采穗圃的营建及管理技术研究

Construction & Management Techniques of Cunninghamia lanceolata Cutting Orchard

通过试验研究杉木采穗圃母株不同定植株行距、母株距根茎处不同截干促萌高度及圃地施用不同种类的基肥对母株产穗量的影响,结果表明:杉木母株定植株行距20 cm×20 cm+母株距根茎部位15 cm处截干+施用1 050 kg.hm-2硫酸钾复合肥作基肥(A3B3C2)组合产穗量最高,母株嫩枝单株年平均产穗量18.8穗,母株硬枝单株年平均产穗量15.9穗。

Different plant densities of the mother plant of Cunninghamia lanceolata, height of sprout-promoting with different cut stem from mother plant to rhizome, effect of different fertilizers on the yield of mother plant rhizome of Cunninghamia lanceolata were studied. Result shows that the highest cutting yield was obtained with the combination of the planting density of Cunningharnia lanceolata 20 cm ×20 cm ＋ cutting height of 15 cm of mother plant ＋ potassium sulfate compound fertilizer （ A3B3C2 ） 1 050 kg . hm^-2 ;annual mean yield of softwood of individual mother plant is 18.8 ear; annual mean yield of soft wood of individual mother plant is 15.9 ear.
