蘆筍之無機營養研究(一)、營養條件對產品質量之影響

Abstract

一、蘆筍為宿根作物，其根之營養生理對嫩莖之產量及品質必定有很大的影響。 二、在田間試驗中，施用3ton/10a之堆肥情形下，使不同氮肥之處理對蘆筍之產量沒有顯著之影響。但化學肥料對土壤理化性質；尤其pH值，交換性鈣，硝酸態氮則有影響。 一、Asparagus officinalis is a perennial crop, so that its root system must play an unequivocal important role. 二、In a field trial bye applying 3 ton/10a of compost as basal treatment, the different nitrogeneous fertilizer treatments resulted no significant difference. But the fertilizer treatments had considerable influence on the soil reaction(PH). exchangeable calcium and content of nitrate nitrogen.
