摘要
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土壤理化性质及产量的影响,旨在为砂姜黑土区花生的高产栽培提供科学依据。结果表明,垄作和土壤调理剂互作能增加土壤p H值和盐分含量,降低土壤水分含量、硬度和容重,提高花生叶片SPAD值,增加花生株高、侧枝长、分枝数、结果枝数,进而提高产量。垄作方式比平作方式花生增产5.7%-12.0%;在平作、垄作方式下,施用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〉生物碳〉腐殖酸。综上,采用垄作并增施秸秆灰分的处理花生产量最高,对土壤理化性质改善较佳,建议在花生生产上示范应用。
The effects of interaction of tillage method（ ridge tillage and conventional flat-tillage） with soil conditioner on soil physicochemical properties and peanut yield were studied by field experiment with split-plot randomized block design,so as to provide scientific basis for peanut high-yield cultivation in lime concretion black soil area. The results indicated that the interaction of ridge tillage with soil conditioner decreased the soil water content,bulk density and surface hardness,increased the soil p H value and salt concentration,leaf SPAD values,plant height,lateral branch length,branch number,fruit branch number. The ridge tillage increased the peanut yield by 5. 7% —12. 0%,compared with conventional flat-tillage. Soil conditioner application increased the peanut yield by 7. 4% —18. 6% under conventional flat-tillage,and 5. 6% —25. 6% under ridge tillage,compared with the treatment without soil conditioner,and the effect order of soil conditioner was straw ash 〉biochar〉 humic acid. Based on these results,the treatment with straw ash under ridge tillage had the highest yield and better improvement for soil,which could be recommended for demonstration application in peanut production.
