摘要: 为了评价栽培制度对连作障碍土壤的修复效果,采用盆栽方式,设置休闲、轮作、间作等处理,以生产中常用的栽培制度即夏季休闲的连作制度为对照,研究各处理对连作8年黄瓜的温室土壤生物修复效果及对后茬黄瓜产量的影响。结果表明,夏季温室休闲期种植青蒜和菠菜及白菜的处理可以显著降低土壤盐分积累,增加土壤微生物数量,抑制镰刀菌的增殖;叶菜-黄瓜-番茄栽培制度较对照收益提高了26.3%,青蒜-黄瓜-黄瓜栽培制度较对照提高了11.6%,黄瓜间作青蒜年收益和对照相近。从本试验的结果来看,填闲和轮作栽培制度可显著改善土壤微生物组成,利于修复连作障碍的土壤。

Abstract: In order to evaluate the restoration effect of cropping systems on continuous cropping soil, treatments of nitrogen-catching crop, rotation, and intercrop were adapted to study soil fertility and microbial indexes of the soil from an 8-year continuous cropping field using pot experiments. Fallow was used as a control (CK). Cucumber yield were recorded. By planting garlic and leafy vegetable, soil salt were significantly reduced, number of soil microbe increased, and the reproduction of Fusarium was inhibited. Income from leafy vegetable-cucumber-tomato treatment increased by 26.3% and that from garlic-cucumber-cucumber increased by 11.6%, while income from treatment of cucumber intercropping garlic was almost the same as that from CK. Therefore, the treatment of leafy vegetable-cucumber-tomato or the treatment of garlic-cucumber-cucumber could improve composition of soil microbe, restore continuous cropping soil, and increase income.

Key words: cucumber, crop rotation, soil microbe, soil fertility
