胡萝卜春季栽培灌水对肉质根开裂的影响

胡萝卜春季栽培,由于低温、干燥等气候条件不利于肉质根的生长,极易发生肉质根开裂等生理障害,进而影响其产品质量,所以采取合理的灌水措施是春季栽培成功的关键。为此,进行了本试验的研究,试验采用灌水次数和灌水量2个因子6种处理,对胡萝卜生长发育、肉质根开裂进行了研究。结果表明:春季栽培灌水保持土壤湿度在70%～80%之间适宜。播种灌水后,每隔15～20天灌水一次,水量0 03～0 05m3/m2,临近收获时不再灌水,这样才能较好地满足肉质根生长,并防止开裂。

Effect of Different Irrigation on Taproot Split of Carrot Spring Cultivation

In spring cultivationof Carrot, because ofarid climate, taproot splittedeasily and then resultedin bad quality. In order to reduce the occurrenceof taproot split and improve the quality, this experiment was conducted tostudy the influence of different irrigation on the occurrenceof taproot split and then get the feasible irrigation measure. The result showed that soil moisture should maintain in 70%～80% in spring cultivationof Carrot.It was suitable for one period of after time sowing, then irrigated at the level of every 15～20 days (quotas was 003 m3/m2～005 m3/m2). It was inadaptable to irrigate once again when close upon harvest.
