玉米育苗移栽技术研究

在平罗县进行了玉米育苗移栽技术试验,结果表明：鲜食玉米品种NDW68产值效益高,具有较高的推广价值;籽粒型玉米F10-3通过育苗麦后移栽能安全成熟,但效益较低;青贮玉米品种ND4产量较高,但除去育苗移栽成本,效益差.从移栽期看,7月4日移栽比7月8日移栽产量高、效益好,表明冬小麦育苗移栽时间越早越好.

A Report on Experiment in Technological of Seedling Raising and Transplanting of Maize

An experiment on the technology of the seedling raising and transplanting of maize was carded out in Pingluo county. The result showed that the product value and the benefit of the fresh-eatable maize variety NDW68 were higher and it had a relatively higher value for popularization; the grain-type maize F10-3 could came to maturity safely with seedling raising and transplanting after wheat but the benefit was relatively lower; the silage maize variety ND4 had a relatively high- er yield but after removing the seedling raising and transplanting cost the benefit was low. As for the transplanting period when it was at July 4 the yield and benefit were higher than those at July 8. It shows that the better it is the earlier the seedling raising and the transplanting are.
