以往春季扦插橡皮树,一般采用盆插,露地插,温度不易掌握,往往造成扦穗下部腐烂,影响成活率。近几年笔者多次试验露地横埋法,发现它是一种较成功的扦插法。 1.建扦插床:在背风向阳处挖一深20厘米、宽80厘米、长120厘米的浅坑(长、宽可根据条件和需要增减),坑内铺满素土,并浇透水。 2.插穗:将橡皮树老条去掉叶片截成10～15厘米的小段,插穗下部最好用利刀削成马蹄状,这样愈合快。 3.横埋:将插穗按照5厘米
In the past, the cuttings of spring rubber trees generally used pots inserted, exposed and inserted, the temperature is not easy to grasp, often resulting in decay lower ear rot, affecting the survival rate. In recent years, many tests of open-field buried Buried Law, I found it is a more successful cutting method. 1. Built cutting bed: In leeward sunny place to dig a deep 20 cm, 80 cm wide, 120 cm long shallow pit (length and width according to the conditions and needs increase or decrease), pit full of plain soil, and drenched water. 2. Cuttings: Remove the old rubber tree leaves cut into small segments of 10 to 15 cm, cutting the lower part is best cut with a sharp knife into a horseshoe-shaped, so healing fast. 3. Buried: the cuttings in accordance with 5 cm
