采用篱式棚膜生产,可成倍增加香椿芽产量,大幅度提高经济效益。具体栽培技术如下: 1.树苗繁育 一般采取种子繁殖,但要注意选用本地种子。我国南北气候冷暖悬殊,香椿在长期的生长发育过程中,形成了各自的生理特性。华北、华中的香椿落叶期较早,而华南地区的香椿落叶期较迟。华南香椿种子若在华中或华北地区播种育苗,秋冬未达落叶休眠期的苗木便会在寒霜下被冻死。也可采取根段育苗。挖取香椿的支根,剪成15—30厘
Hedge-type shed film production, can be doubled the production of Toon Geru, significantly improve economic efficiency. Specific cultivation techniques are as follows: 1. Sapling generally take seed breeding, but pay attention to the selection of local seeds. China’s north-south climate disparities, toon in the long-term growth and development process, formed their own physiological characteristics. The stems of Toona sinensis in North China and Central China had earlier deciduous, while the Toona sinensis in South China had a later deciduous period. If South China Toona sinensis seed sowing seedlings in central China or in northern China, autumn and winter dormant less than the leaves of nursery stock will be frozen in the cold frostbite. Can also be taken root section nursery. Dig toon roots, cut into 15-30%
