| 中文摘要 | 廄肥係一種維持地力的有機肥料,本試驗的目的乃在探討施用廄肥對於青割玉米產量與品質及土壤地力之影響,及含銅之廄肥施用後重金屬銅在土壤或植體中是否會累積。供試材料為玉米(Zea mays)臺農351號,於76年秋作、77年春作及秋作、及78年春作各種植一次,每次均分別以含氮100、200及300kg/ha之牛糞或豬糞再加化學肥料施用,及只施含氮400kg/ha之牛糞或豬糞,並以化學肥料為對照。施用廄肥後會增加土壤中氮、磷及鉀之含量,但不會增加土壤中銅含量,青割玉米的產量會隨著廄肥施用量之增加而提高,全施豬糞者可達到最高的產量;秋作的產量比春作為高。玉米果穗與稿稈中銅含量沒有顯著差異,全株銅含量不受廄肥種類或施用量之影響,玉米植體中粗蛋白質含量除全施牛糞組較低外,其餘各廄肥處理間無顯著差異,磷酐及氧化鉀含量則隨著牛糞或豬糞施用量之增加而提高,總可消化養分在各廄肥處理間也無顯著差異。因此施用牛糞或豬糞於青割玉米田,除能提高青割玉米之產量及品質外,且能改進土壤地力,重金屬銅也不會在土壤及植體中累積。 |
| 英文摘要 | Animal manure is an organic fertilizer to maintain soil fertility. Objectives of this experiment were to determine effects of anmimal manures on forage yield and quality of forage maize (Zea mays) and to determine if heavy metal, Cu, was accumulated n corn plants or soil applied with Cu –containing animal manures. Corn, CV. Tainung no. 351, was planted in fall 1987 spring and fall 1988 and spring 1989, respectively. Cattle and hog manures containing N 100, 200 and 300 kg/ha added with chemical fertilizer were applied, or cattle and hog manures containing N 400 kg/ha were applied only. Chemical fertilizer treatment was used as control. The amounts of N, available P and K were increased in soil when cattle and hog manures were applied. The Cu level in soil was not enhanced when Cu-rich hog manure was applied. Forage yield was the highest among the treatments as hog manure was applied only. Higher yield was obtained in fall crop season than in spring crop season. No difference in Cu level was observed between cob and straw. The Cu level in whole plant was not affected by kinds and amounts of manures applied. Crude protein in plants was not significantly different among manure treatments except for that applied with cattle manure only. The levels of P₂O and K₂O in plants were increased when more cattle or hog manures were applied. The percentages TDN were also not significantly different among manure treatments. It showed that cattle or hog manure applied in soil could increase forage yield and quality of forage maize and improve soil fertility. Further, no Cu accumulation was observed in both corn plant and soil. It was suggested that animal manure might be applied in soil to maintain forage productivity and soil fertility. |
