但在20日齡窩仔數和窩重性狀上，雜種公豬優于純種公豬。 -
The work on seasonal dynamics of litter input and decomposition and the relationship between them and environmental factors was studied through the method of harvest and weight loss. soil respiration rate was measured by alkali - absorption method and the contribution from soil microorganism respiration and from root respiration was determined through trendline method of linear regression between soil respiration rate and belowground biomass. mathematical models were established between the seasonal dynamics of main components of soil total respiration including soil respiration, root respiration, soil microorganism respiration, litter respiration and environmental factors
應用收獲法和重量損失法對枯枝落葉輸入與分解的季節動態及其與環境因子的關系進行了研究；應用靜態氣室法測定了土壤總呼吸和凋落物呼吸，應用土壤呼吸量與地下生物量線性回歸趨勢線法測定了土壤微生物呼吸及根呼吸的貢獻量，運用相關分析法建立了土壤總呼吸、根呼吸、土壤微生物呼吸及其凋落物呼吸季節動態與環境因子之間的數學模型；應用灰色分析比較了兩群落土壤呼吸季節動態產生差異的原因；應用干重換演算法對土壤微生物能量積累量的季節動態進行了測定，建立了土壤微生物能量積累量與環境因子的數學模型；應用系統分析方法，利用分室模型，對兩群落枯枝落葉與微生物之間的能量流動進行了定量測定和穩定性分析。
