铁岭地区鲜食糯玉米不同播种期与栽培方式试验
|
摘要
对铁岭地区鲜食糯玉米的播种期及栽培方式进行研究,结果表明:随着播种期由4月7日推迟至4月21日,玉米生育期有逐渐变短的趋势,从124 d缩短至103 d;且播种越早,田间玉米的病虫害发生越轻。铁岭地区播种期以4月7—14日为佳,并采用小拱棚营养钵保温育苗加地膜覆盖栽培技术,可较对照正常露地栽培产量增加17.2%,且差异显著(P<0.05)。在播种期相同的情况下,各种栽培方式对小区玉米产量的影响不存在显著差异。本结果可促进铁岭地区鲜食糯玉米提早上市、增产增收。
The current research investigated the effects of different sowing dates and cultivation methods on the growth and yield of waxy maize for fresh consumption planted in Tieling area in 2016. The results showed that with the sowing date postponed from April7 to April 21, there was a tendency for the waxy maize to have a shorter growth period, which was reduced from 124 days to 103 days.On the other hand, when the maize was sown earlier, there was a lower incidence of diseases and pests in the maize field. April 7-14 was found to be the optimal period for sowing waxy maize for fresh consumption in Tieling area. Moreover, the cultivation method was shown to influence its yield; compared with the conventional method of growing the maize in the open-air field, an innovative method(growing seedlings in pots placed in a small arch shed coupled with mulching the maize field with plastic film) significantly(P< 0.05) increased the yield of waxy maize by 17.2%. However, with the same sowing date, various cultivation methods did not affect maize yield to a significant extent. These findings are conducive to increasing the yield of waxy maize for fresh consumption and putting it on the market ahead of time.
