Introduction to seven Ye Shupu

selection and soil preparation

七叶树(Aesculus chinensis Bunge)又名梭椤树、菩提树、七叶枫树,是七叶树科七叶树属的落叶大乔木,其树形绚丽,挺拔文雅,是世界四大行道树之一,也是漂亮的庭荫树。随着城市园林绿化的疾速开展,对七叶树苗木的需求量越来越大。笔者近几年停止了七叶树播种育苗实验,积聚了较为丰厚的经历,现将七叶树播种育苗技术总结如下。

Buckeye (Aesculus chinensis Bunge) also known as spindle tree fern, banyan tree, seven Ye Feng tree, is a large deciduous trees of the genus hippocastabaceae buckeye, brilliant tree, tall and elegant, is one of the four big trees in the world, is also a beautiful shade trees. Rapid carried out along with the urban landscape greening, the buckeye seedling demand more and more big. I stopped the buckeye semination experiment in recent years, accumulated a relatively rich experience, now the buckeye semination technology summarized below.

选择生长强健、无病虫害、枝繁叶茂、坚固多的中壮年母树。采

集时间以8月下旬至9月上中旬果实成熟时为宜,此时的种子最为丰满,成熟度和质量也较好。采种时间过早,种子生理成熟度不够,发芽率低,长势弱。采种时间过晚,种皮开裂,易腐朽生虫,发芽率会受影响。果实采集后应堆放在墙角阴凉通风处,上面掩盖草席或麻袋,促进外果皮零落、开裂,每天翻动数次,避免腐朽。但堆放时间不能超越3d,也不能在烈日下曝晒,选择丰满、色泽正常、无病虫害的种实。将分级后的纯洁种子用1∶3湿沙混匀,湿度以手握成团,手松触之即开为宜,在背风向阳、土壤潮湿、排水良好的场所,挖土坑储存,并且留好通气孔,在贮藏过程中,要经常检查,以防霉烂或受干。

Choose to grow strong, no plant diseases and insect pests, the flourishing and strengthened more mature trees. Acquisition time in late August and September occurrence peak advisable, when ripe seeds at this time the most plentiful, maturity and good quality too. Not enough seed time too early, the seed physiological maturity, low germination rate, growth weak. Seed production time is too late, skin cracking, easy rotten insect, germination percentage will be affected. Fruit acquisition should be stacked in the corner of the room after a cool and ventilated place, above the cover straw mat or sacks, promote exocarp is shattered, craze, turning every day several times, to avoid rot. But stacking time is not beyond 3 d, also

can't in the hot sun exposure, select plump, colour and lustre is normal, no plant diseases and insect pests of solid. After grading the purity of seeds with 1:3 wet sand blender, humidity in hand together, openhanded touches that is advisable, in the leeward sunningdale, drainage good places, soil moisture, digging holes is stored, and leave a good vent, in the storage process, often should check, in case of mildew or dry.

选择背风向阳、土层深沉、pH值为中性或微酸性、排水良好,距水源较近、交通便利的肥美壤土地域作为播种用地。育苗地应于秋末深翻,并且施入有机肥30~50t/hm2,过磷酸钙750kg/hm2。播种前要停止细致整地,肃清杂草和石块,使空中平整,土粒粗细平均。做成宽1.0~1.2m,长因地形而定的畦,并灌透水。播种前7d用0.5%的硫酸亚铁溶液喷洒床面,停止土壤消毒。也可在播种时,将适量的硫酸亚铁粉沫与细土等量混合平均撒入床面或播种沟内。在杀菌消毒的同时,还要用辛硫磷500~800倍液喷洒床面或播种时施入播种沟内杀虫。

Choose leeward sunningdale, soil deep, pH value is neutral or slightly acidic, good drainage, is apart from water, convenient transportation of rich loam region as the land for sowing. Seedling should be on the commune deprivation, and into the organic fertilizer rates 30 ~ 50 t/hm2, superphosphate 750
