摘　　要：对香椿温室栽培技术进行了试验研究。主要包括 1品种对比 ,山东曹县红香椿最佳 ,采芽量超过其它品种 3 4 % ;2栽植密度 ,以 40株 /m2为最好 ,但有待进一步研究 ;3截干高度 ,以 1 .5 cm为最佳 ,每株平均生芽数为 3 .3 7个 ;4矮化激素 ,效果最佳者为多效唑 (PP333) ;5突破顶芽试验 ,喷施 0 .0 0 5 %赤霉素 (92 0 )最好 ,在 1 5天内有 80Study was conducted of Chinese mahogany culture in greenhouse.The content and results of the study are as follows. 1)variety contrast.The red mahogany from Cao county of Shandong is best,whose bud yield is higher than others by 34%. 2)Planting density.The density of 40 trees/m 2 is best,but the further study is needed. 3)Stem cutting height.The optimum cutting heightis 1 5 m,average bud number 3 37. 4)Dwarf hoemone.pp 333 has the best effect. 5)Breaking phyllogen test.Spraying 0 005% gibberellin is the best measure,about 80% of plants breaking phyllogen in 15 days.
