摘要: 为了明确不同有机肥对荸荠的施用效果,以“台荠1号”为供试品种,常规施肥为对照,研究了5种常用有机肥配施化肥对荸荠生长发育及产量、品质、口感的影响。试验结果表明:施用有机肥比单一施用化肥增产显著,但不同种类的有机肥,对荸荠的品质和口感影响差别较大。施用饼肥、鹌鹑粪、羊粪等能使荸荠高产质优;施用牛粪肥产量较高,但对荸荠的品质改善效果不明显;施用猪粪肥能使荸荠增产,但食味淡且略带咸味、多渣少水、口感硬、顶芽长、种皮发黒、品质差,据市场调查,价格比同级球茎下降三分之一,农户应避免施用。

Abstract: In order to learn the effect of farmyard manure on Chinese water chestnut (Eleocharis dulcis), we assessed the yield, quality and taste of the elite cultivar“Taiqi 1”on different sources of farmyard manure and the chemical fertilizer. Sources of farmyard manure included rapeseed meal, quail dung compost, sheep dung compost,cow dung compost and swine dung compost. The chemical fertilizer was used as control. Results showed that all the farmyard manures significantly improved yield of water chestnut. However, the effects of different farmyard manure were significantly different on the quality and tastes of water chestnut. Rapeseed meal, quail dung compost and sheep dung compost were effective to improve the quality of water chestnut but cow dung compost were not effective. Negative effects on quality of water chestnut were from swine dung compost, which bring water chestnut light salty taste. Moreover, water chestnuts from the swine dung compost tasted hard and waterless. Terminal buds were longer as well. Seed coat was darker. These negative effects caused bad quality of water chestnut and resulted in 33% of price decrease in market. Farmers should avoid swine dung compost in water chestnut growing.
