采用田间试验,利用秸秆露地挖穴对越橘生长的土壤进行改良,测定高丛越橘品种"蓝丰"和半高丛越橘品种"圣云"改土后土壤pH值、土壤有机质、植株生长和产量的变化。结果表明:玉米秸秆和园田土体积比1∶1的处理,土壤pH值由原来的6.87降为4.18, 土壤有机质含量由园田土的2.16%提高到5.89% 植株的高度、粗度、基生枝长度和延长枝长度等生长指标均比对照有所提高 单果重和单株产量也明显高于对照,"蓝丰"和"圣云"2个品种单株产量分别是对照的158.9%和154.8%。说明该处理对越橘生长效果较好。
Soil of blueberry growth was amended by added to straw with hole-digger in a field experiment. The soil pH, soil organic matter, plant growth and yield of 'bluecrop' and 'St. cloud' cuhivar were determined. The result showed that soil pH decreased from 6.87 to 4. 18 in treatment of corn residues and garden soil(v : v= 1 : 1), which was lower than the comparison and suit for blueberry growth; Soil organic matter content increased from 2. 16% to 6. 89% ; The height, width, length-shoots and the length of extend branches of plato was higher than the comparison. The single fruit weight and single bush production was higher than control too, single bush yield of two cultivar were respectively 158. 9% and 154. 8% than control, which demonstrated that the treatment of corn residues and earth(1 : 1) was good for growth of blueberry.
