- 摘要:
- 对河北省不同生产基地鸭梨的产量、果实品质因子和外界因素进行了调查,用逐步回归分析法进行统计,以探讨鸭梨产量和果实品质与外界因素之间的关系。结果表明:土壤速效钾含量和灌水量对形成产量有较大的正效应;叶果比对产量有较小的负效应。生长季的降雨量对果实可溶性固形物含量有较大的负效应;叶果比对果实可溶性固形物含量是正效应。土壤有机质含量对果实单果重有较大的正效应。各项因子与鸭梨产量、单果重和可溶性固形物含量的相关系数均未达到差异显著水平。在保证果实可溶性固形物含量11.0%以上,667 m2产量在3 500 kg左右的水平,壤土类型、有机质含量在4.6 g/kg以上的果园,生长季降水量在530.9~554.9 mm的情况下,全年灌水量在150 mm左右,即可满足梨树对水分的需求。
- Abstract:
- The yield,fruit quality factors and external factors of different pear production in Hebei Province were investigated.The results were counted by stepwise regression analysis,in order to explore the relationship between pear yield,fruit quality and the external factors.The results showed that it had a greater positive effect the amount of soil potassium,irrigation on pear yield.Leaf-fruit ratio and soil available phosphorus content had a smaller negative effect on the yield.The rainfall during growing season had a greater negative effect on fruit soluble solids content(SSC).Leaf-fruit ratio on fruit SSC had a positive effect.Soil organic matter content on singale fruit weight had a greater a positive impact.The correlation coefficient of various factors to pear yield,single fruit weight and SSC did not reach the level of significant differences.To ensure the fruit SSC of 11.0% above;the yield of 3 500 kg/667m2,the annual volume of irrigation about 150 mm was essential to meet the water needs of the pear in the case of loam type,organic matter content of more than 4.6 g/kg orchards,growing season precipitation in the 530.9~554.9 mm.
