【摘要】 经过2000~2001年两年试验,育苗面积66.7m2,每定植667m2大葱生产田,用种100g育出的葱苗数量少,满足不了定植需求;用种150~250g育出的葱苗质量高,数量充足,生产出的鲜葱质量和产量较高,是适宜用种量范围;用种300~450g育出的葱苗质量不高,达到壮苗标准的葱苗较少,种子浪费较多,生产出的鲜葱质量和产量较低,不宜提倡。更多还原

【Abstract】 Teach the seedling area 667m~2 and than transplant the spring onion seedling to the farmland of 667m~2 in the two years trial(2001～2002),the spring onion seedling that taught with 100 grams of seed was scarce and could not satisfy to plant;the spring onion seedling that taught with 150 grams of seed was ample,the spring onions seedling quality standards and yields is higher, so it is a well scope for seed quantity;the quality of the spring onions seedling that taught with 300～450 grams of seed was low-grade,the seed waste more,the fresh spring onion quantities and yields is lower,should not promote.更多还原
