本文主要是阐述黄瓜对氮磷钾的养分吸收规律。黄瓜对氮磷钾等养分的吸收是随着生育期不同而变化的,陆地栽培黄瓜和温室栽培黄瓜的养分吸收量也有很大的区别。整个生育期内黄瓜对钾的吸收量最大,氮次之,磷最小,不同器官对营养元素的吸收量顺序不同,根为K>N>P,茎也一样,叶为N>K>P,瓜为K>N>P,黄瓜在生长发育过程中,氮磷钾的含量在不断变化。黄瓜植株鲜重含N0.302%,P0.076%,K0.218%;瓜果鲜重含N0.135%,P0.022%,K0.188%。
This article is mainly about cucumber nutrient uptake of nitrogen, phosphorus and potassium. The absorption of nutrients such as nitrogen, phosphorus and potassium cucumber is with the growth period varies, the amount of nutrient absorption of land-grown cucumber and greenhouse cucumber cultivation are also very different. The amount of potassium absorbed by cucumber was the highest during the whole growth period, followed by nitrogen and phosphorus, and the order of nutrient uptake by different organs was different. The roots were K> N> P, the stems were the same, and the leaves were N> K> P, Melon for K> N> P, cucumber in the process of growth and development, nitrogen, phosphorus and potassium content is constantly changing. Fresh weight of cucumber with N0.302%, P0.076%, K0.218%; fresh fruit weight with N0.135%, P0.022%, K0.188%.
