一、在採種前應調查,瞭解产種地區的主要樹種、母樹年齡、結實情形、产量多少、有无病、虫害以及採集時期,貯藏方法、地点等,都须事先作好准备。二、除选择有造林价值,没有病虫害,发芽力强的種籽外,在我省应注意採集防止風砂,保持水分,消滅山荒砂荒的造林樹種。如橡、櫟(俗名柴樹)、胡枝子(條)、紫穗槐、白蜡、松、杆、侧栢、椿、榆、槐、胡桃、山桃、山杏、漆樹等。因為這些樹種生长迅速,在短時 First, should be investigated before planting, understanding the main species of production areas, tree age, strong situation, yield, disease-free, pests and collection time, storage methods, locations, etc., must be prepared in advance. Second, in addition to the choice of afforestation value, no pests and diseases, strong germinating seeds, in our province should pay attention to prevent the collection of sand, water, eliminate wasteland shortage of afforestation tree species. Such as oak, oak (common name Chai Shu), Lespedeza (bar), Amorpha fruticosa, white wax, pine, pole, oriental arborvitae, Chun, Yu, Huai, walnuts, peach, apricot, tree and so on. Because these species grow rapidly in short time
