摘要：

以田园土壤栽培为对照，研究了以农业废弃物腐熟麦秸与腐熟大粪干及洁净土壤等为主要原料配置而成的富有机质土壤限根和非限根栽培对大白菜产量和品质的影响。结果表明，富有机质土壤非限根栽培的大白菜生长势好，根系活力强，叶绿素含量高，增产效果显著，产量较对照提高了20.68%；亚硝酸盐未检出，硝酸盐含量降低了359mg/kg，降幅达38.26%，富有机质土壤非限根栽培还明显增加了大白菜叶球的干物质含量,增幅为17.2 %；与对照相比, 富有机质土壤非限根栽培的大白菜的粗蛋白含量、总糖含量和维生素C含量分别提高了4.9%、0.9 %和2.44 %。表明富有机质土壤非限根栽培方式对提高白菜产量及改善营养品质效果良好。

Abstract:

Abstract: The effects of organic soil(mixture of decomposed corn stalk, manure and soil) to the Chinese cabbage in plant growth, yield and nutrient quality in solar greenhouse were studied compare to ordinary soil cultivation(CK). The results showed that the plant under organic soil cultivation growth better than CK, which has higher plant height and stem diameter. The root activity and photosynthesis rate of organic soil is better than CK. And at final, the yield of Chinese cabbage were increased and nutrient quality of Chinese cabbage were improved, the mature stage will be earlier than CK. Comparing with root non-restriction culture，root restriction by a plastic film will decrease the leakage of the nutrient atoms and water to keep a suitable fertility level, so it will saving water and fertilizer. The root activity of root restriction organic soil will higher than organic soil without film. Organic soil cultivation will increased tomato chlorophyll a, chlorophyll (a + b) content in leaves; and organic soil with film root restriction significantly increase the tomato yield and improve tomato nutrient quality. The root restriction by film will saving water and increase soil fertility, so it is a environmental friendly technique in protected horticulture.. The results showed that soil organic matter-rich non-limited cultivation of Chinese cabbage root growth potential, and root activity, and high chlorophyll content, yield significant output increased 20.68% in control; reducing nitrate content of 359mg/kg.
