摘要
采用相关分析法分别确立了早春设施厚皮甜瓜果实横径、纵径,果实鲜重、干重,果肉厚度,果实含水量与果实发育有效积温的相关关系,建立最优回归方程。结果表明:模型能较好地对甜瓜果实横径、纵径,果实鲜重、干重,果肉厚度和果实含水量进行模拟;模拟值与观测值回归估计标准误差(RMSE)分别为:0.6166 cm、0.5088 cm、5.874 g、8.7748 g、0.1423 cm和0.9529%;模型对早春设施厚皮甜瓜果实横径、纵径,果实鲜重、干重,果肉厚度和果实含水量的模拟值与实测值符合度较好,实用性较强。
Using correlation analysis methods respectively definite the correlativity between the process of melon＇s fruit development on diameter, longitudinal diameter, fruit weight： fruit dry weight, pulp thickness, fruit water content and the effected accumulated temperature and establish the optimal regression equation in early spring. The models were validated by different areas and different varieties. The results showed predicted results were agreed well with the actual ones. RMSE for fruit diameter, fruit longitudinal diameter, fruit weight, fruit dry weight, pulp thickness, fruit water content were 0. 6166, 0. 5088, 5. 874,8. 7748, 0. 1423 cm and 0. 9529% respectively. The established models were applicable and could provide theoretical basis and decision support for the melon＇s quality formation in early spring.
