摘要
为探索适合大连地区的蚕豆生产栽培方式,在冬季温室和早春露地开展试种栽培试验,分别研究了冬季温室中不同育苗方式和不同播种深度,以及早春露地不同穴播粒数和不同播种时期对蚕豆生育期及农艺性状的影响。结果表明,冬季温室栽培,蚕豆直播苗较移栽苗生育期短,长势强,产量高,播种深度以10 cm为宜;早春露地栽培,单粒穴播蚕豆单株农艺性状表现好,但综合产量略低于双粒穴播处理,故生产中应选择双粒穴播以增加产量,其播种时期以4月3日为宜。
A broad bean cultivation experiment was conducted in winter greenhouse and early spring open ground to explore the culti-vation methods suitable for Dalian. The effects on growth periods and agronomic characters of different raising seedling methods, sow-ing depths, seeding numbers per hole and sowing dates were studied. The results showed that in winter greenhouse, seedlings of direct seeding had stronger vigor, higher yield and shorter growth period than transplanting seedlings, and appropriate seeding depth was 10 era; in early spring open ground, agronomic characters of one seed per hole treatments were superior to two seeds per hole treatments, but the total yield were less, indicating that two seeds per hole treatment was optimal method for high yield in production, and the op-timal sowing period was 3^nd April.
