浙江萧山萝卜干肉质鲜美、产量高、抗逆性强,易于种植和加工。这些优良品质除了与品种有关外,还与其产地的土壤地质和地球化学背景密切相关。与浙江平原土壤元素平均值对比,产地的MgO、B、P、CaO、Mn含量较高,N、K、Mo、Fe、Zn含量较低;从该区土壤养分和微量元素有效态分析结果来看,碱解氮、Fe、Mn、Cu含量丰富,速效磷、有机质和Zn含量一般。由于产地土壤成熟度不高,加上该区复种指数高等问题,造成土壤N、K流失和B、Mo缺乏,影响和制约了萝卜的产量和质量。建议及时追加微肥和有机肥,做到科学养地。
" Xiaoshan dried radish" is characterized by deliciousness, high yield, high anti-weather change capability and easy growing and processing. These fine qualities are related closely not only to the species but also to the soil geological and geochemical background of its producing area. Compared with soil average element values of Zhejiang plain, the producing area has higher MgO, B, P, CaO and Mn but lower N, K, Mo, Fe and Zn. Viewed from the effective state analytical results of soil nutrients and trace elements, the area contains abundant nitrogen of alkaline hydrolysis, Ge, Mn and Cu and an average amount of rapid available phosphorus, organic matter and Zn. As the soil maturity of the producing area is relatively low and the cropping index there is high, N and K in the soil tend to flow away, and B and Mo are deficient, which affects and restricts the yield and quality of the radish. It is suggested that trace element manure and organic manure should be added in time so as to maintain soil fertility in a scientific way.
