T active immunization could maintain its castration for a period, at the age of 11w, the development of combs and wattles were evidently slower in the immunized groups ( p < 0. 05 ), and the testes atrophied. meanwhile, both its serum t concentration and body weight were evidently lower than the untreated group. 2. the does of 0. 2mg / ml produced the best immunisation performance and promotion growth effecct, we could induce the dosage was the main factor in deciding the final effect, injection at w3 achieved the best result
11周齡時，各免疫組雞體重、血漿睪酮含量顯著（ p 0 . 05 ）低於對照組，睪丸及冠垂發育受到抑制，明顯發生萎縮，其中以0 . 2mg / ml劑量， 3周齡免疫抑制作用最為明顯；此後隨著日齡的增長，免疫抑制作用逐漸下降，到15周齡時，免疫抑制作用明顯逆轉，機體的生長發育恢復正常，免疫各組與對照組相比測定指標無顯著性差異（ p 0 . 05 ） ；至19周齡，各免疫組睪丸和冠垂生長發育、體重、血漿睪酮含量都顯著（ p 0 . 05 ）高於對照組，其中以0 . 2mg / ml劑量組， 9周齡免疫促生長作用最為明顯。 -
The result of experimentation on coupling effect of water and fertilizers on spring corn in the three gorges reservoir area indicate that water stresslead the effect low of highness and lai, and the most effect is made in shooting stage ; it has a significant positive correlation between the yield of corn and biomass, and hasn ' t none significant positive correlation between the yield of corn and the weight of roots ; the coupling effect of water and n is significant, but the coupling effect of water and k is not significant, the maximum yield of corn condition fitting - water and medium n, corn absorbs n has a threshold value during the growth, and using superfluous n is able to prick up soil drought and crop drought ; water is the leading factor which effects the yield of corn, next is n and k
摘要三峽庫區春玉米盆栽水肥耦合試驗研究結果表明，水分脅迫導致玉米株高和葉面積指數降低，以拔節期受到影響最大；玉米產量與生物量呈顯著正相關關系，產量與根重無顯著正相關關系；水氮耦合效應顯著，適宜水分和中氮處理下玉米的產量最高，玉米生長發育對氮肥的吸收存在一定的閾值，過多施用氮肥會加劇土壤乾旱和作物乾旱，水和鉀耦合效應對玉米產量影響不顯著；水分是影響玉米產量的主導因素，其次是氮效應和鉀效應。
