| 摘 要： | 目的]为智利牧豆和牛蹄豆的引种栽培提供理论依据。方法]以智利牧豆和牛蹄豆为材料,通过引种栽培试验研究2个物种的苗木生长状况和育苗、移苗技术。结果]温水浸泡处理可提高牛蹄豆的种子发芽率;智利牧豆较牛蹄豆出苗快,从播种到真叶出现仅需6~10 d,而牛蹄豆需9~12 d;播种3个月后,智利牧豆和牛蹄豆平均苗高生长量分别为2.56、5.91 cm,平均基径生长量分别为0.030、0.060 cm。智利牧豆和牛蹄豆的生长旺盛期分别在7~8月和8~9月;切根并喷洒生根剂处理的智利牧豆成活率最高,为96.7%。结论]该试验为智利牧豆和牛蹄豆的引种栽培及大田推广提供了参考。

| Abstract: | Objective] The study was to provide the theoretical basis for introduction and cultivation of Prosopis chilensis L.and Pithecellobium dulce.Method] With P.chilensis and Pithecellobium dulce as materials,the growth status of the seedling and the techniques of seedling-raising and seedling-transplanting of the 2 species were studied through test of introduction and cultivation.Result] The treatment of soaking with warm water could increase the seed germination rate of Pithecellobium dulce.The seedlings of P.chilensis emerged faster than that of Pithecellobium dulce,from sowing to true leaf emergence,the P.chilensis only needed 6～10 d,but Pithecellobium dulce needed 9-12 d.After sowing for 3 months,the average increment of seedling height of P.chilensis and Pithecellobium dulce were 2.56,5.91 cm resp.,and their average increment of basal diameter were 0.030,0.060 cm resp.The vigorous growth stages of P.chilensis and Pithecellobium dulce were from June to July and from August to September resp.The treatment of cutting roots and spraying rooting reagent could increase the survival rate of P.chilensis,being 96.7%.Conclusion] The test provided the reference for the introduction and cultivation and field extension of P.chilensis and Pithecellobium dulce. |
