猕猴桃园绿肥还田对土壤肥力及猕猴桃产质量的影响

Effects of Returning Green Manure to the Field on Soil Fertility and Kiwifruit Yield and Quality

为加快果园绿肥种植技术推广,建设高产优质、绿色环保的果园,采用小区重复试验,于2015-2017年连续进行不同模式猕猴桃果园间种绿肥还田试验,研究果园一年冬夏两季绿肥连茬免耕撒播种植和冬季绿肥免耕撒播种植还田对果园土壤培肥效果及果实产质量的影响。结果表明:果园间种绿肥还田,均可逐步提高土壤有机质含量和土壤养分,降低土壤容重,改善土壤物理性状,从而提高耕地质量,提升果品品质及产量;一年冬夏两季绿肥连茬免耕撒播种植还田在果实产量、品质和提高土壤养分、改善土壤理化性状等方面均比冬季绿肥免耕撒播种植还田效果明显。

The effects of different returning green manure to the field patterns （double green manure continuous no-tillage spreading planting pattern in a year and green manure no-tillage spreading planting pattern in winter during 2015--2017） on soil fertility and kiwifruit yield and quality were studied by a plot repeated test to speed up popularization of green manure planting technique in orchards and build the orchard with high yield, high quality, green and environment protection. Result： The returning green manure to the field pattern in a kiwlfruit orchard can gradually increase soli organic matter and nutrients content, reduce soil bulk density, improve soil physical properties, which results in improvement of farmland quality and promotion of fruit quality and yield. The fruit yield, fruit quality, soil nutrients and soil physical and chemical properties under the double green manure continuous no-tillage spreading planting pattern in a year are obviously higher than under the green manure no-tillage spreading planting pattern in winter.
