中文摘要: |
在辽宁西部阜新旱作农业示范区进行田间试验,探讨了深松中耕对这一地区土壤养分及玉米产量的影响。结果表明:与传统耕作相比,深松中耕能够提高0~30 cm土层土壤有机质含量及0~20 cm土层土壤全N、P、K含量,以提高0~10 cm土层土壤全N含量最为显著(P<5%);能够增加0~20 cm土层土壤碱解氮含量及0~30 cm土层土壤有效钾含量,以增加0~10 cm土层土壤有效钾含量最为显著(P<5%);显著增加10~30 cm土层土壤有效磷含量(P<5%);增加了玉米产量,增加幅度为7.80%。 |

This paper discussed the effect of inter-tillage on soil nutrients and corn yield by field experiment in dry-farming agricultural demonstration area of Fuxin in Liaoning Province. The results showed that, compared with traditional cultivation, deep loosening cultivation increased the content of soil organic in 0~30 cm soil layer and the content of total N, P and K in 0~20 cm soil layer, and it improved significantly the content of soil total N (P<5%). It increased the content of alkaline hydrolytic nitrogen in 0~20
cm soil layer and the content of available potassium in 0~30 cm soil layer, and increased significantly the amount of available potassium in 0~10 cm soil layer P<5%). Deep loosening cultivation also increased significantly the content of available phosphorus in 10~30 cm layer(P<5%). Thus it increased t
he corn yield in this area, and the range of increase was 7.80%. |
