一、串叶松香草的特性 串叶松香草原产于拉丁美洲潘帕斯草原,1979年我国从朝鲜引进该草,先后在不同地区进行栽培试验,经观察,串叶松香草在北纬34°的中纬度地区的中性及略偏碱性土壤生长良好,且喜大水大肥。在中等水肥条件下.每亩年产鲜草可达10吨,高水肥条件下达15吨。 该牧草为多年生草本植物,在冬季温度-14℃条件下,覆盖3—5厘米树叶或粪土即可顺利越冬。3年龄后牧草不覆盖可顺利越冬。 该牧草耐干旱性能较差。轻沙质土壤栽培的串叶松香,在夏季日平均气温25～27℃时,每5天需浇水一次;27～30℃时,每3天需浇水一次;高于30℃时,每2天需浇水一

First, the characteristics of Slash leaf vanilla Slash leaves native to the Latin American Pampas grassland, 1979, the introduction of the grass from the DPRK in North Korea, successively in different regions for cultivation experiments, the observed Slash leaf herb at latitude 34 degrees north The mid-latitudes of the neutral and slightly alkaline soil growth is good, and hi big water and fat. Under moderate water and fertilizer conditions, the annual output of fresh grass per acre up to 10 tons, 15 tons of high water and fertilizer conditions. The forage is a perennial herb that can successfully winter when covered with 3-5 cm leaves or soil at a winter temperature of -14 ° C. 3 years after the grass does not cover the winter can be smooth. The herbage has poor drought tolerance. Sesbania rosin cultivated in light sandy soil should be watered once every 5 days when the daily mean temperature in summer is 25-27 ℃; watering is carried out once every 3 days at 27-30 ℃; when it is above 30 ℃, 2 days to water one
