为了提高芹菜生产的经济效益,满足市场的需要,我们于1984—1987年进行了一次栽植、三次平茬收获的塑料大棚生产技术研究,取得了亩收芹菜25000公斤、经济效益提高四倍的结果。现将栽培技术综合如下: 一、及早育苗,培育壮苗早育苗有利于早栽植,延长芹菜的营养生长期。适播期为五月下旬。苗床宜择壤土,并施足基肥,精细整地;播前对种子进行浸种催芽(将种子用清水浸泡12—24小时,用湿布裹着吊在水井内,离井水面30—40厘米,或置在阴凉处3—4天);播种采取条播或撒播的办法,为保证播种均匀,以条播为好;
In order to improve the economic benefits of celery production and meet the needs of the market, we conducted a study on the production technology of plastic greenhouse harvested three times in 1984-1987 and obtained 25000 kg of harvested celery per mu, resulting in a quadrupling of economic benefits . The cultivation techniques are integrated as follows: First, early nursery, nurturing seedlings Early nursery is conducive to early planting, extending the vegetative growth of celery. Suitable sowing period for late May. Seedbed should choose loam, and apply enough base fertilizer, fine preparation of land; before sowing the seed germination (the seeds soaked with water for 12-24 hours, wrapped with a damp cloth hanging in the well, 30-40 cm away from the well water, or 3-4 days in the shade); sowing to sow or sow the way, in order to ensure sowing uniform, sowing is better;
