摘要:
在不同肥力水平大棚土壤上设置不同氮肥供应水平的田间试验,结果表明,增施氮肥能够提高黄瓜产量16. 0% ～ 45. 8% ,但每kg 氮的增产量随着施氮量的增加而下降, ; 黄瓜氮肥利用率随着施氮量的增加和土壤供氮水平的提高而降低。盆栽试验结果表明,适宜的氮肥用量有利于改善黄瓜品质,而过量施氮使黄瓜果实中Vc含量降低和硝酸盐含量增加。利用修正的Stanfo rt施肥公式计算保护地黄瓜优质高产施氮量切实可行。
Abstract:
The pot and plot ex periment s in g reenhouses show ed that certain amount of N application increased the yield and improved the quality of cucumber. High N application brought the ratio of N fertili zer abso rbed by cucumber dow n. The Vc content s in f riut of cucumber reduced and the ni trate increased when the Nwas applied at high lev els. The Stanfo rt ’s formula, F = N c - Ns R f , is useful for calculating the amount of N fertilizer in cucumber field in the g reenhouse. In the experiumental conditions, the fo rmula isN = Ym C - N aRs 22 Rf in which N is the amount of N fertilizer for cucumber g row th; Ym is the yidle of cucumber f rom 75 to 106t per ha according to the fertili ty of the soil; C is 3. 0 that is the Kilog rams of N absorbed by cucumber when harv esting one to n f resh f ruit; Na is alkakine hydoly tic N of soil and Rs is the ratio of N absorbed by cucumber f rom soil that is 0. 36; Rf is the ratio of N assimilated by cucumber f rom N fertilizer with the rang e f rom 0. 40 to 0. 29.
