Effect On The Sweet Potato Qulaity And Cultivation Of Weather

The effect of climate on sweet potato has been carried out in many fields. The paper focuses on the analysis of qualities of two different special kinds of sweet potato(high starch type which used as industrial raw material and edible type)in different regions of Anhui and under different weather conditions.The study was conducted on the farm of Taihe,Guichi and also on the farm of Anhui agricultural university simultaneously.The experiment studied the growing and developing and quality of different sweet potato in different climate condition. Analysis the relationship between climate factor and sweet potato by statistical method.The results can be shown as fellowing:1.The average daily temperature is most helpful in generating starch and the daily temperature difference has the biggest influence on the content of solubility sugar.The sunshine is most affected on protein and the rain decline has the biggest influence on the accumulation of vitamin.2.Climate factors can also affect the yield of sweet potato,the relationship between average daily temperature,rainful and sweet potato yield is negative; the relationship between accumulated temperature,light and sweet potato yield is positive;3.High temperature can fast the sprout of sweet potato and the temperature is playing very important role in the development of sweet potato seeding.And accumulated temperature170℃is good,and sweet potato seeding has been discussed.4.From the experiment,combining results of principal yield and multifactor regression analysis,cultivation of sweet potato in An hui.the equation of cultivation of sweet potato can be shown:T1 =- 154.3256+ 0.00000146X + 01000058Y +0.0369H.5.Climate factor is important to the sweet potato quality and yield.Climate factor is playing very impotent role in the process of sweet potato quality and yield.Compareing two factors,genetype and environment,environment factor is more important.The high quality and high yield can be united,because the fittest affecting them is accordant.Through the methods,such as varieties,climate zone etc.To get high quality and high yield of sweet potato is possible.
