覆盖方式对高海拔冷凉区胡萝卜生长发育的影响

Effects of Mulching Mode on Growth and Development of Carrot in High-altitude Cold Areas

在甘肃河西走廊沿祁连山高海拔冷凉气候区连续2a开展了覆盖方式对胡萝卜生长发育的影响研究。结果表明:采取覆盖方式栽培胡萝卜,对胡萝卜商品性状和产量的影响不显著,但可使产品上市期提前,效益显著增加。利用小拱棚+地膜覆盖方式种植胡萝卜可在7月初上市,较常规不覆膜栽培提早上市65d,667m2产值提高3倍;地膜覆盖栽培胡萝卜上市期较露地常规不覆膜栽培提早25d,在7月下旬成熟,667m2产值是露地常规不覆膜栽培的2倍。

A field experiment was carried out to investigate the effects of mulching mode on growth and development of carrot for two consecutive years in Hexi corridor high-altitude cold areas.The results showed that commodity character and yield of carrot were no significant differences under different mulching cultivation mode.While could make the product listed earlier,a significantly increase in effectiveness under mulching cultivation mode.Small Shed plastic film mulching cultivation of carrots could be listed in early July,compared to the open field cultivation,the listing of 65 days in advance,the output value increased by three times.Plastic film mulching cultivation of carrots listed compared to open conventional no mulching cultivation of early 25 d,mature in late July,the output value was two times.
