一、平贝为百合科植物,以鳞茎入药。有清热润肺,止咳化痰的作用。主产东北,尤以吉林省通化产量最多。河北、陕西有引种栽培。二、生长习性野生平贝多长在山区林下及溪流两岸腐殖质丰富,疏松肥沃,较湿润的地方。喜冷凉、湿润的气候,耐寒,东北能安全越冬。喜疏松肥沃的砂壤土。粘土地、砂地及低洼地不宜种植。平贝是喜冷凉湿润气候,怕炎热干燥的植物。野生平贝多生长在山区河边,沟旁下坡土质疏松,含腐殖质丰富湿润的微酸性或中性土壤中。三、栽培技术 (一)选地整地种平贝必须选择土质肥沃、疏松,土层深厚,渗透力强背风向阳的砂质壤土,和具备排灌条件的山问平地种植,不符合上述条件的土地,不宜种植平贝。选肥活疏松的黑土或细砂土,春季化冻后翻耕,经过晾晒,把土耙细作成高畦,畦的高低,可视地势来定,地势高的地方畦可低些,地势低的地方畦宜上高些。一般畦高13-20厘米,畦宽1.0-1.3米,长随地形而定,畦沟30-50厘米,量地划线后,把畦床内的表土翻到畦沟上,挖深沟10—13
First, the flat shellfish for the Liliaceae to bulbs into medicine. Have heat lungs, cough and phlegm role. The main producing northeast, especially in Jilin Province Tonghua output up. Hebei, Shaanxi has introduced cultivation. Second, the growth habit of wild Betta long in the mountains and streams along the banks of humus rich, loose and fertile, more humid place. Hi cool, humid climate, cold, the Northeast can safely wintering. Loose loose sandy loam soil. Clay, sand and low-lying land should not be planted. Flat shell is like wet and humid climate, afraid of hot and dry plants. Wild Betula grew in the mountain river, ditch next to the soil loose, rich humus rich acidic or neutral soil. Third, the cultivation techniques (A) the selection of land preparation Pingbei must choose fertile soil, loose, deep soil, strong leeward sandy sandy loam, and with irrigation and drainage conditions Hill planting, do not meet the above conditions of land , Should not be planted flat shellfish. Selection of fertile loose black soil or fine sand soil, after the spring tillage after tilling, after drying, the soil rake fine made into high, high, low, depending on the terrain to be set, high terrain can be lower, low-lying areas畦 should go higher. General 畦 high 13-20 cm, 畦 wide 1.0-1.3 meters, with the long terrain, 畦 trench 30-50 cm, the amount of dashing, the 表 bed topsoil into the ditch, dug deep trench 10 -13
