中文摘要: 提出了总奶产量等于生理产奶量加营养产奶量和气候产奶量,即:Y总= Y1+ Y2+ Y3,并重点讨论气候产奶量Y3和营养产奶量Y2。结果表明,各月平均水汽压、月平均气温、月平均最低气温和月蒸发量4个因子对气候产奶量影响较大,同时找出1988年的各月平均水汽压,1993年月平均气温,1989年月平均最低气温和1988年月蒸发量4个最佳气象条件的相似年,它们最利于提高气候产奶量。其
Abstract:It is pointed out that the total milk yield is equal to the physiological milk yield plus nutrition milk yield and climate milk yield,that is,Ytotal=Y1+Y2+Y3.It is focused on the climate milk yield and nutrition milk yield. The result shows that the four factors,ie,monthly average vapour pressure,monthly average air temperature,monthly average lowest temperature and monthly average evaporation,have great effect on the climate milk yield.Meanwhile,the best conditions in the monthly average vapour pressure (1988),monthly average air temperature (1993),monthly average lowest temperature (1989) and monthly average evaporation (1988) are the most favourite for the climate milk yield .The cause of the low milk yield was given,that is,the milk production peak is postponed for 30 days.What’s more,if the seed amaranth can be planted to make up for the cow food shortage during July and August,there is a potential milk production increasement of 1 million kilograms.
