摘要
香蕉叶片每月生长数与月均温呈极显著正相关,花期长短与初花期的旬均温呈极显著负相关,果穗重、果指重与花芽分化初期的旬均温呈极显著负相关,而与旬雨量呈极显著正相关。果穗重、果指重及可食率与≥15℃的积温呈极显著正相关。果穗重还与初花期的旬均温呈极显著正相关。在水湿条件较好的果园,香蕉生长发育与降雨量的关系不显著。建立了上述各相关的数学模型,可用于预测香蕉生长发育状况和果实品质。
The result of experiment showed that there was a highly significant,positive cor- relation between the number of leaves growing from a banana plant per month and mean monthly temperature,yet there was a highly signficant,negative correlation between the length of flowering phase and average temperature in ten days(ATTD)in the early flowering stage.Significance test revealed that the bunch weight and finger weight were negatively cor- related with ATTD in early flower-bud differentiation stage with highly significance,but positively correlated with accumulated temperature higher than 15℃ with highly significance.There was also a highly significant,positive correlation between bunch weight and ATTD in the early flowering stage.It showed that the growth and development of bana- na were correlated with rainfall wirh no significance.Some mathematical models were set up in this paper,which could be used for estimating the growth and development of banana and the fruit quality.
