耕作方式与土壤调理剂互作对花生产量和品质的影响

采用大田裂区随机区组设计试验，研究了耕作方式(垄作、平作)与土壤调理剂互作对花生产量及品质的影响。结果表明，垄作方式比平作方式花生增产5.7％~12.0％；无论是平作或垄作方式下，与对照相比，施用不同土壤调理剂均能使花生增产，增产幅度分别为7.4％~18.6％、5.6％~25.6％，不同土壤调理剂对花生增产的大小顺序为秸秆灰分>生物炭>腐植酸。垄作和土壤调理剂互作能显著增加花生的饱果数、百果重、出仁率、花生株高、侧枝长、分枝数和结果枝数，提高花生籽粒中的氮、磷和钾含量，增加花生蛋白质和粗脂肪的产量。本试验条件下，采用起垄与增施秸秆灰分互作的处理的花生产量、蛋白质产量和粗脂肪产量均最高。

Effects of tillage method and soil conditioner interaction on peanut yield and quality

The effects of tillage method and soil conditioner interaction on peanut yield and quality were studied by field experi-ment with split-plot randomized block design. The results indicated that the ridge planting method increased the peanut yields by 5. 7% ~12. 0%, compared with flat planting method. Obviously, soil conditioner application increased the peanut yield by 7. 4% ~18. 6% in flat planting method, and 5. 6% ~25. 6% in ridge planting method treatment, compared with control, respectively. According to the effect of improving the peanut yield, soil conditioner treatments was ranked as straw ash>biologi-cal carbon>humic acid. The study showed that the interaction of ridge tillage and soil conditioner application not only increased the peanut full pod number, 100-pod weight, kernel rate, plant height, lateral branch length, branch number, valid branch number, but also increased the peanut kernel nitrogen, phosphorus and potassium contents, protein and crude fat yield as com-pared to control. In particular, the interaction of ridge planting method with straw ash treatment had relatively high peanut pod, peanut kernel protein and crude fat yield in this study.
