本文报道了地膜覆盖对梨果实品质的影响及果实的生长模型。6年的研究表明,覆膜可以改善梨果实的外观性状。在覆膜对挂果量不超出对照树10％的水平时,均可有效地增大果形,提高果实的级别。同时,覆膜可使果实可溶性固形物含量有一定程度的增加,并减少裂果,提高果实的商品性。 本文同时报道覆膜与对照梨树果实横径与纵径的生长模型,并用数学方法对生长模型进行了分析。证明覆膜果实生长速率高于对照,果实生长发育加快,极限生长量预测值大于对照。
The paper reports the effects of plastic film mulching on the quality of pear fruit and the fruit growth model. Six years of research have shown that the film can improve the appearance of pear fruit. In the coating on the fruiting amount does not exceed the control tree level of 10%, can effectively increase the fruit shape, improve the fruit level. At the same time, the film can make the fruit soluble solids content increased to a certain extent, and reduce the cracked fruit, improve the commercial fruit. In the meantime, the growth model of the diameter and the longitudinal diameter of the pear and the control pear were covered. The growth model was also analyzed by mathematical method. The results showed that the fruit growth rate was higher than that of the control, the growth and development of the fruit was accelerated, and the predicted value of the limit growth was greater than that of the control.
