| 为探寻种植于年均温度偏低地区四季蜜芒反季节成花效果不理想，花期延后，产量低或果实品质差的解决方法和依据。本试验以5年生四季蜜芒为研究对象，开展了果园露地种植和防草布覆盖对四季蜜芒土壤温度和含水率，冠层温湿度，成花物候期和成花率，产量和品质影响的田间试验。结果表明：与露地种植相比，防草布覆盖提高四季蜜芒0-20cm土层土壤含水率和平均温度；冠层最高和平均温度分别提高0.2-5.9℃和0.4-1.5℃，降低平均和最低湿度；提早四季蜜芒开花7-10天，成花率提高26.0%；产量提高30.8%；果实可溶性固形物含量和糖酸比分别提高17.1%和33.9%，果实果皮细腻，无或极少斑点。覆盖防草布提高土壤温度和含水率及冠层温湿度，提早四季蜜芒反季节栽培成花时间和提高成花率，提升产量和品质，适合在年均温度偏低种植区推广应用。 |

| To solve off-season Sijimi-mango poor and delayed flowering, low yield or quality planted in low average temperature area. The study will take 5 year old Sijimi-mango as research subject, and investigate the effects of open field cultivation and mulch anti-weed sheet on soil average temperature and water content, canopy temperature and humidity, flower phenology and flower rate, yield and quality. Compared to open field cultivation, mulch anti-weed sheet increased 0-20cm soil mean temperature and water content, enhanced canopy maximum and average temperature by 0.2-5.9℃ and 0.4-1.5℃, early flowered for 7-10 days, increased flower rate and yield by 26.0% and 30.8%, enhanced Soluble Solids and Sugar /acid by 17.1% and 33.9%, and fine skin and without or few spots. mulch anti-weed sheet increased soil mean temperature and water content, canopy maximum and average temperature, early flowered and increased flower rate ,improved yield and quality, thus it can be promoted on off-season Sijimi-mango planted in low average temperature area. |
