杜仲是近年来一直走俏的中药材,也是提炼橡胶的好材料。由于需要量大,生长周期长,今后相当长时间难以满足市场需求。笔者在近几年的栽培中,取得了很好的经济效益,并摸索到一套杜仲速效栽培的方法。 1、培育壮苗:培育壮苗是速生快长的关键措施。栽培上可采用两段育苗,方法是将种籽先集中播于小面积内,待长到3—4片针叶时再按一定的株行距排栽。这样育苗的好处一是节约种籽,且前期集中播于小面积内便于管理,出苗率高。二是小苗栽到大田后稀密一致,苗匀、苗壮,当年能长到3—4厘米,而且根系发达,栽后不会长成小老树。具体做法大致和棉花的方格育苗或玉米的肥团育苗相同。 2、秋栽:秋季雨量充沛,气温适宜成活率高,而
Eucommia has been popular in recent years, Chinese herbal medicines, but also a good material for refining rubber. Due to the large demand and long growth cycle, it is difficult to meet the market demand for a long time. In the cultivation of the author in recent years, I got very good economic benefits, and found a method of quick-effect Eucommia cultivation. 1, nurturing seedlings: nurturing strong seedlings is the key to fast growing fast. Cultivation can be two sections of nursery, the method is to focus on the first sowing in a small area of the seed, to be grown to 3-4 pieces of needle and then row spacing plant spacing row. One of the benefits of this nursery is to save the seed, and pre-concentrated broadcast in a small area within easy management, high emergence rate. Second, the seedlings planted to the field after the dense dense, Miao Miao, Zhuang Zhuang, then grow to 3-4 cm, and well-developed root system, will not grow into small trees after planting. The specific approach is roughly the same with the cotton boxed nursery or corn fattening nursery. 2, autumn planting: abundant rainfall in autumn, the temperature suitable survival rate, and
