近年来,为满足市场对野生蔬菜的需求,笔者连续多年试行荠菜的人工栽培,且逐步探索出一整套大蒜与荠菜优化复种新技术。因荠菜植株矮小,分布于蒜株底层空间,可有效地截获剩余光资源(即蒜株间散光),提高群体光能利用率。1994年,我县菜农示范推广的300余亩复种田,亩均产值逾3000元(蒜薹600kg×1.20、蒜头850kg×0.80元、荠菜1800kg×0.90元)。经济、社会效益极为显著。其复种要点:
In recent years, to meet the market demand for wild vegetables, the author for many years of artificial cultivation of shepherd’s purse, and gradually explore a set of garlic and shepherd’s purse to optimize the new technology. Because shepherd’s purse plants are short and distributed in the bottom space of garlic plants, the remaining light resources (ie, astigmatism between garlic plants) can be effectively intercepted to improve the utilization rate of light energy of the group. In 1994, our county farmers demonstration and extension of more than 300 acres of mu farming, mu output value of more than 3000 yuan (garlic sprouts 600kg × 1.20, garlic 850kg × 0.80 yuan, shepherd’s purse 1800kg × 0.90 yuan). Economic and social benefits are extremely significant. The multiplication points:
