摘要
利用日光温室火龙果花期和果实生长期的历期、温度和光照观测资料,采用钟模型和有效积温模型建立了2个发育期的模拟模型,并对模拟效果进行了检验和对比。结果表明:火龙果在花期和果实生长期均具有较高的感光性和感温性,气温越高、光照条件越好,火龙果花果的生长速度越快;钟模型对火龙果花期和果实生长期的模拟效果优于有效积温模型,其决定系数分别为0.95839和0.95655,NRMSE分别为4.6%和7.7%,RMSE分别为0.78和2.63 d。
Based on the observation data of the flowering and fruit-growing stages of pitaya,two prediction models for the developmental stages of the flowering and fruit-growing stages were established by the clock model and the effective cumulative temperature model,and the simulation effects were tested.The results showed that pitaya had high sensitivity to light and temperature during flowering and fruit growth,the higher the temperature and the better the light conditions,the faster the growth rate of dragon fruit and flowers.The simulation of the clock model was better than the effective cumulative temperature model,with coefficients of determination(R^(2))of 0.95839 and 0.95655,NRMSE of 4.6%and 7.7%,and RMSE of 0.78 d and 2.63 d,respectively.
