砂仁属姜科豆蔻属多年生草本经济植物,高1—2米。夏季开花,秋季果熟。一般3—4年开花结果,6年左右进入盛果期,可连续收获十年以上。经济价值高,是热区群众脱贫致富的好门路。现将栽培管理技术介绍如下: 一、栽培地选择砂仁属热带半阴性植物,忌阳光直射。要求植区海拔约1000米以下,年平均温度22℃左右。全年无霜或偶有轻霜,荫蔽度50—60％,其荫蔽树种以树冠高大、常绿、根深的杂木阔叶林为佳。砂仁为浅根性高杆植物,陡坡地遇风易倒伏,故坡度宜在25°以下的缓坡和斜坡、土壤多以疏松、肥沃、排水良好的砖红壤或赤红壤上种植较好。亦可考虑与芭蕉、木瓜、果树、橡胶等经济林间作。二、繁殖及栽培技术砂仁的繁殖主要有种子繁殖和分株繁殖两种:
Amomum ginger family Myristica perennial herb economy plant, 1-2 meters high. Summer flowering, ripe fruit in autumn. The general 3-4 years flowering results, about 6 years into the flourishing period, can be more than 10 years of continuous harvest. High economic value is a good way for the people in the hot zone to get rid of poverty and prosperity. Cultivation management techniques are introduced as follows: First, the cultivation of sand is a selection of tropical semi-negative plants, avoid direct sunlight. Requires about 1000 meters above sea level planting area, the annual average temperature of about 22 ℃. Annual frost-free or occasional light frost, shade of 50-60%, its shade trees with tall, evergreen, deep root of the hardwood broad-leaved forest is better. Amomum asparagus plants, steep slopes in the wind prone to lodging, so the slope should be 25 degrees below the gentle slopes and slopes, the soil is more loose, fertile, well drained brick red soil or red soil planting better. Can also be considered and banana, papaya, fruit trees, rubber and other forest for intercropping. Second, the breeding and cultivation techniques Amomum seed multiplication and reproduction of two main ramets:
