据《中国农学通报》2015年第31期《不同抗旱措施对“东试早”柚产量及品质的影响》(作者黄菁等)报道,为解决西双版纳季节性干旱对“东试早”柚开花结果的影响,以10年生东试早柚为试材,采用随机区组试验设计,连续2年开展黑地膜覆盖、白地膜覆盖、杂草覆盖、添加保水剂和常规管理措施的田间比较试验,研究不同抗旱措施对柚园土壤容重、营养和产量及品质的影响。结果表明,覆草处理下不同土层土壤容重最小,孔隙度最大,而覆盖薄膜后土壤容重最大,孔隙度最小。不同处理土壤营养元素含量随时间变化差异较大,
According to the report of “Chinese Agricultural Science Bulletin” 2015 the 31st “Different Drought Resistant Measures to ” East Test early “pomelo yield and quality impact” (the author Huang Jing, etc.) reported that in order to solve the seasonal drought in Xishuangbanna "Pomelo flowering results, with 10-year-old test pomelo as the test material, using a randomized block design, for two consecutive years to carry out black film mulching, white film mulching, weed coverage, adding water retention agent and conventional management measures Field trials were conducted to study the effects of different drought control measures on the bulk density, nutrition, yield and quality of pomelo garden soil. The results showed that the soil bulk density was the smallest and the porosity was the highest in different soil layers under mulch treatment, while the soil bulk density was the largest when the film was covered and the porosity was the smallest. Different treatment of soil nutrient content varies greatly with time,
