胡萝卜机耕高垄栽培模式研究

Study on High Ridge Cultivation Mode of Carrot

为探索胡萝卜机械化起垄栽培的最佳模式,设计了一垄双行、宽垄4行、窄垄4行3个处理,以一垄双行为对照,测定不同栽培模式下胡萝卜植株的长势、产量、商品率和整齐度等指标。结果表明,宽垄4行和窄垄4行的产量相当,分别为59457.0和59764.5 kg/hm^(2),但窄垄4行的商品整齐性较差,边际效应明显,不建议采用;宽垄4行胡萝卜商品性较好、整齐一致、单根重0.16 kg左右,可适用于南方地区单根重相对较小的胡萝卜生产;一垄双行的产量虽然略低,但胡萝卜肉质根个大、条直、整齐性好,可以适用于北方地区单根重相对较大的胡萝卜生产。

In order to explore the best mode of mechanized ridging cultivation of carrot,three treatments of one ridge and two rows,wide ridge and four rows and narrow ridge and four rows were designed.The growth vigor,yield and commodity rate of carrot plants under different culti-vation modes were measured by one ridge and two rows behavior control.The results showed that the yield of wide ridge four rows and narrow ridge four rows were 59457.0 and 59764.5 kg/hm^(2),respectively,but the commodity uniformity of narrow ridge four rows was poor and it was not recommended.Wide ridge four rows of carrots had good commodity,uniform,single weight about 0.16 kg,which could be applied to the production and use of carrots with relatively small single weight in southern China.Although it was slightly lower,the fleshy roots of carrot were large,straight and well-organized,which could be applied to the production and use of carrot with relatively large single root weight in northern China.
