- 摘要:
- 以欧李园土壤为研究对象，设计了高垄种植欧李+地布覆盖（H）、沟作种植欧李+地布覆盖（D）、平作种植欧李+地布覆盖（F）处理，以沟作种植欧李（CK）作为对照，研究了生长季节内（5—9月）3种处理对土壤温度、湿度与果实品质的影响。结果表明：白昼20 cm土壤温度随日照时间的延长，H、D处理高于CK，F处理低于CK，但增温幅度H>CK>D>F；生长期间土壤温度先升高后降低，H、D、F处理在09:30前土壤温度均高于CK。生长季节内 20 cm土壤湿度先降低后升高，生长前期（5月15日前）D处理湿度较高，生长中期（7月13日前）H处理高于D、F和CK，但D、F处理低于CK，生长后期（7月31日后）3个处理均低于CK。3种处理下（H、D、F），果实平均可溶性固形物含量分别比CK提高了5.79%、11.09%和7.30%，平均酸含量分别比CK降低了23.65%、25.15%和15.75%，果实平均硬度分别较CK降低了15.86%、5.82%和2.58%，平均单果质量、平均果实含水量也较CK降低。3种地布覆盖方式均能对土壤起到保温、保湿的作用，在雨季具有降低土壤湿度的作用，可明显改善鲜食欧李的品质。
- Abstract:
- Soil of Chinese dwarf cherry was taken as research object.Chinese dwarf cherry plants were grown in covered high ridges (H),ditches (D) and flat grounds (F) respectively to study their effects on soil temperature,soil humidity and fruit quality of Chinese dwarf cherry in the growing season (May to September).Chinese dwarf cherry grown in ditches without ground cover were used as control.The results were as follows:The soil temperature (20 cm-underground) in the daytime gradually increased with the prolongation of sunshine for all 3 treatments (H,D and F) and the control.Treatment H and D were higher soil temperature than the control while treatment F was lower soil temperature than the control.However,the sequential order of temperature increase amplitudes were H>CK>D>F.In the growing season,the soil temperature (09:30 am) of all treatments exhibited a pattern of increasing firstly and then declined.Additionally,treatment H,D and F had higher soil temperature than the control during the whole growing season.The soil humidity (20 cm-underground) of all treatments decreased firstly and then increased in the growing season.Treatment D had the highest soil humidity in the early stage of the growing season (before May 15th) and the sequential order of soil humidity in the middle stage of the growing season (from May 15th to July 13th) was H>CK>F>D.The soil humidity of the control was higher than other three treatments in the late stage of the growing season (after July 31st).The average fruit soluble solid contents of treatment H,D and F increased by 5.79%,11.09% and 7.30%,respectively comparing with that of the control while their average fruit titratable acid contents decreased by 23.65%,25.15% and 15.75% and their average fruit firmness also decreased by 15.86%,5.82% and 2.58% respectively.The average single fruit weight and average fruit water content were also lower than those of the control.In conclusion,ground covering could not only preserve the soil temperature and humidity,but also reduced soil moisture in the rainy season and increased the fruit quality of Chinese dwarf cherry.
