Relationship between Cucumber Fruit Growth and Microclimate in Solar Greenhouse
In order to improve the prediction ability sunken sunlight greenhouse cucumber fruit growth,greenhouse cucumber fruit growth indicators response to the micro-climatic factors,to establish greenhouse cucumber fruit growth day number and small climatic factors of the relationship between model and the analysis,established based on a number of small climate factor cucumber fruit volume increment prediction model,and the independent test data prediction test.The results showed that:the coefficient of variation of the same plant in different periods of cucumber growth of days required is relatively large,the minimum value is 37.3%,the maximum value is 48.1% ;the comprehensive and independent correlation analysis,selects the 11 ~34 ℃ effective accumulated temperature the same day,daily range of air temperature and daily average relative humidity both 1 d ago as predictors of cucumber fruit volume increment,pursuant to which the model of greenhouse cucumber fruit volume increment predicted and measured values of the independent data fit better,relative error of 29.06%,and the coefficient of determination was 0.78,and has good portability.For the sunken greenhouse cucumber in the analysis and prediction of growth and yield model can be used.
