本试验重点研究玉米育苗移栽几个关键技术措施 ,同时进行 0 .5hm2 生产示范试验。结果表明 ,在吉林地区最适播期为 4月 17日左右 ;品种应选生育期为 14 0～ 14 5d ,积温 2 90 0℃晚熟品种。如丹 70 3品种 ;营养土配比可采用 6 0 %豆田土 +2 0 %草炭土 +2 0 %EM堆肥 (用 0 .2 %EM菌处理鸡粪 )或腐熟鸡粪 ;育苗方式采用营养方 (8cm× 8cm)。生产示范比大田增产 17.0 7%。
This experiment focuses on maize seedling transplanting several key technical measures, at the same time 0. 5hm2 production demonstration test. The results showed that the optimum sowing date in Jilin was about April 17; the varieties should have a growth period of 14 0 ~ 14 5 days and accumulated temperature of 2 90 0 ℃. Such as Dan 70 3 varieties; nutrient soil ratio can be 60% soy bean soil +20% peat soil +20% EM compost (with 0.2% EM bacteria treatment of chicken manure) or decomposed chicken manure; nursery mode of nutrition Square (8cm × 8cm). Production demonstration 17.0 7% increase over the field.
