采用篱式棚膜可生产出优质香椿芽,成倍增加产量,大幅度提高经济效益。具体栽培技术如下:一、树苗繁育一般应采用本地种子繁殖,也可挖取本地香椿的支根,剪成15—30厘米长的小段,进行扦插繁殖,只要苗圃肥沃,肥水管理得当,不论是扦插还是播种繁殖,均可在年内成苗。二、篱式定植即在1米宽的畦床上,以30厘米的株距纵向密植两行,行距亦为30厘米,畦间距70—80厘米。一般于冬闲整地作畦时在畦中挖一道深沟,施足优质有机肥,尔后覆土过冬。翌春当香椿 Hedge-type shed films can produce high-quality Toon buds, doubling the output, significantly improve economic efficiency. Specific cultivation techniques are as follows: First, the sapling breeding should generally be the use of local seed breeding, but also to dig out 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, Cutting or planting and breeding, can be planted in the year seedlings. Second, the fence-type planting that is 1-meter-wide broom bed to 30 cm plant density two rows of vertical density, spacing is also 30 cm, 畦 spacing 70-80 cm. Generally in the winter when the land preparation for the 畦 digging a deep trench, Shi enough quality organic fertilizer, and then cover the winter soil. The next spring when toon
