小冠花(Coronill varia L.)豆科小冠花属多年生植物,据说引自美国多变小冠花,种名不清。它是优良的绿肥和牧草,适于作荒山荒地和果园的覆盖物,或者作轮歇地轮歇期间增加覆盖,恢复地力的绿肥、牧草来种植。水土流失特别严重的徒坡荒山,作为防冲刷、保水土的先锋作物更为理想。为研究小冠花在我区的生长表现,探索其利用途径和方法进行引种试验。1980年夏从山西农业大学土壤农化教研室引进带荚种子8克,9月用少量带荚种子播种一盆出苗22株。1981年5月送到沾益县沾益公社光华十队果园旁荒地定植18株,成活17株。1981年5月13日在光华十队果园荒地上播种一平方米,5月23日出苗,7月7日苗高15厘米
Corolla variabilis (Coronill varia L.) Leguminosae is a perennial plant, reportedly quoted from the United States changing small crown, species name unclear. It is an excellent green manure and pasture that is suitable for covering barren hills and orchards, or for planting green manure and pasture with increased coverage and resilience during a disruptive rotation. Soil erosion is particularly serious hillsides, as anti-scouring, retaining the soil of the pioneer crops is more ideal. In order to study the growth performance of Corolla flower in our district and to explore the ways and methods for its introduction. In the summer of 1980, 8 grams of pod seeds were introduced from the Department of Soil Science and Cultivation of Shanxi Agricultural University. In September, 22 seeds were planted in a pot with a small amount of pod seeds. In 1981 May sent to Zhanyi County Zhanyi Guanghua ten orchards next to the wasteland planting 18, 17 survived. On May 13, 1981, one square meter was planted in the orchard wasteland of the ten brightest groups of Guanghua, and the seedlings were sprouted on May 23 and the seedling height was 15 cm on July 7
