大棚绿色豆芽颜色鲜绿,质地脆嫩,营养价值较高,在生产过程中不施肥、不打药,无污染,具有投资少、生产周期短、效益高的特点。一般5～15天一茬,全年可连续种植35天左右。主要栽培技术如下: 一、品种选择大豆种类很多,按种皮颜色可分为黄豆、青豆、红豆、黑豆等。各种大豆都能生产豆芽菜,按其产量质量和经济效益讲,首先是红豆,它的种皮薄,发芽快,产出比在1:10左右。病害少,芽瓣色泽鲜亮,芽梗脆嫩,纤维含量少,适口性强,营养丰富,对环境适应性强,一年四季都可种植。其次是黑豆,它的种皮厚、发芽略慢,产出比在1:12左右,芽瓣色泽略暗,适口性差,有药用价值,种子价格比红豆低。二、种子处理为提高芽菜的整齐度和质量,首先
The green bean sprouts in the greenhouse are of bright green color, crisp texture and high nutritional value. They do not fertilize, fight drugs or pollution in the production process, and have the advantages of less investment, short production cycle and high efficiency. Generally 5 to 15 days a crop, throughout the year can be planted for 35 days or so. The main cultivation techniques are as follows: First, the variety of varieties Many varieties of soybeans, according to the seed coat color can be divided into soybeans, green beans, red beans, black beans and so on. All kinds of soybeans can produce bean sprouts, according to its production quality and economic efficiency, the first is red beans, its seed coat is thin, germination, output ratio of 1:10 or so. Less disease, bright bud color, bud crisp tender, less fiber content, palatability, nutrient-rich, adaptable to the environment, can be planted throughout the year. Followed by black beans, its seed coat thick, germination slightly slower, the output ratio of about 1:12, slightly darker bud color, palatability is poor, with medicinal value, the seed price is lower than red beans. Second, the seed treatment To improve the uniformity and quality of sprouts, first of all
