分析得出:河西各地由于生态气候的差异,苹果梨具有明显的地域分布和时间特征。分析得出:民乐县园艺场苹果梨果实生长发育动态呈“S”型曲线增长,得出7月上旬至8月中旬是果实膨大关键期;果实膨大的适宜气温为15觸21℃。全生育期需稳定通过≥7℃积温2300觸2800℃。品质形成期(9月上旬至10月上旬)要求凉爽的气候,在适温范围内,日较差大,光照充足,有利于可溶性固性物含量的积累和着色,品质好。在分析的基础上,用影响苹果梨产量和品质的主要气象制约因子将河西划分为五个气候适生区。
The analysis shows that apples pear has obvious geographical distribution and time characteristics due to the difference of ecological climate in all parts of Hexi. The results showed that the fruit growth and development of apple pear showed a “S” curve in the horticultural field of Minle County. The results showed that the early July to mid-August was the key period for fruit enlargement. The suitable temperature for fruit enlargement was 15 to 21 ℃. The whole growth period to be stable by ≥ 7 ℃ 2300 touch 2800 ℃. Quality formation period (early September to early October) requires a cool climate, in the temperature range, the daily difference between the large, adequate light, is conducive to the accumulation of soluble solids content and coloring, good quality. Based on the analysis, Hexi was divided into five climatic suitable habitats with the main meteorological factors that affect the yield and quality of apple pear.
