1、树苗繁育。选用本地种子进行繁育。同时也可挖取本地香椿的支根,剪成15-30厘米长的小段,进行扦插繁育。只要苗圃肥沃,肥水管理得当,均可在年内成苗。 2、篱式定植。在1米宽的畦床上,以30厘米的株距纵向密植两行,两行间的行距亦为30厘米。畦与畦间的距离为70—80厘米。一般于冬闲时整地作畦并在畦中挖一道深沟。施足优质有机肥,然后覆土过冬;也可以在春季肥沃的地块上进行。翌春当香椿树苗尚未萌发时,按上述株行距定植于施肥沟的两侧。 3、幼篱肥培。定植1-2年的幼篱管理重在固培根,头年只摘取株位过高的主芽,促发低位侧芽;第2年保存矮苗主芽,使篱内各株的生长趋同一高度,形成整齐丰满的篱垣形式。 4、成篱管理。①成篱的整形修剪。当年椿芽采收后,及时短截长枝,矮化篱垣。使篱垣保持在1米以
1, sapling breeding. Use local seeds for breeding. At the same time can also tap the local roots of Toona sinensis, cut into 15-30 cm long pieces, cutting propagation. As long as nursery fertile, fertilizer and water management properly, can be planted in the year seedlings. 2, Hedge colonization. On a 1-meter-wide broom bed, two rows are planted longitudinally at a spacing of 30 cm. The spacing between the two rows is also 30 cm. The distance between 畦 and 畦 is 70-80 cm. Generally in the winter when the soil preparation for 畦 and dig a deep ditch. Apply enough high-quality organic fertilizer, and then cover the winter; also fertile plots in the spring. The next spring when toon sapling has not yet germinated, according to the plant line spacing planted in fertilizer ditch on both sides. 3, hedge fertilizer. In the first year, only the main bud with high plant height and the low lateral bud were picked out, and the main bud of the seedling was preserved in the second year, which made the growth of each plant in the hedge converge to the same Height, forming a neat and plump hedge form. 4, hedge management. ① heddling plastic trim. After the spring buds harvest, timely cut short branches, dwarf fence fence. Keep the fence at 1 meter
