南昌北郊温度与草莓花量、花期、果实大小的相关分析

CORRKELATION ANALYSIS BETWEEN TEMPERATURE AND THE AMOUNT OF STRAWBERRY BLOSSOM、BLOSSOM PERIOD AND FRUIT SIZE IN THE NORTH SUBURB OF NANCHANG CITY,JIANGXI

分析了南昌北郊温度对草莓花量、花期和果实大小的相互关系。得出：１．旬平均气温＜８．０℃不开花，１０～１２．０℃开花量最大，＞１５．０℃迅速减少。２．花期的旬平均气温８．０～１２．０℃形成大果，１４．５～１７．０℃形成中果，＞１８，０℃小果增加。３．形成草莓产量关键期的温度指标是：候温１１．７～１７．７℃之间，旬温１０．０～１７．７℃之间，日均温１３．０℃左右，开花授粉可获得较高的产量和较优质的果实。

The correlation between the temperature and the amount of strawberry blossom, blos-som period and fruit size in the north suburb of Nanchang city was studied.The results were:1. The strawberry didn′t blossom when the average,air temperature of ten days(A.T.T.)isbelow 8.0℃. The amount of blossom is the largest when A.T.T. is between 10.0～12.0℃,Then it reduces when A.T.T.is above 15.0℃.2. The fruit size is the largest when A.T.T.is between 8.0～ 12.0℃,The size is medium when A.T.T.is 14.5～ 17.0℃.Andthe size is small when A.T.T. is above 18.0℃.3.The temperature of the key period for theformation of yield of strawberry is:11.7～17.7℃averaging in five days,10.0～17.0℃ av-eraging in ten days. about 13.0℃averaging daily. Higher yield and quality of the fruit canbe obtained by pollination in blossom under the above temperature conditions.
