以“新泰密刺”黄瓜为试材,通过盆栽试验,研究了玉米、小麦秸秆不同用量对日光温室黄瓜连作土壤理化性状的影响。结果表明:施用作物秸秆后的土壤容重随秸秆施用量增加而降低,孔隙度和有机质含量却随秸秆施用量增加而增加;与对照相比,施用1.6%~2.0%的玉米秸秆和2.0%的小麦秸秆显著降低了土壤容重,增加了孔隙度;土壤有机质和土壤速效养分含量以施用鸡粪的处理最高;施用适量作物秸秆在一定程度上能提高连作土壤碱解氮和速效钾含量;但是,施用秸秆的处理土壤速效养分含量均低于施用鸡粪。
A pot experiment was conducted to study the effects of corn and wheat straw dosage on the physical and chemical properties of cucumber continuous cropping in sunlight greenhouse. The results showed that the bulk density of soil decreased with the increase of straw application, and the porosity and organic matter content increased with the increase of straw application rate. Compared with the control, corn straw with 2.0% 2.0% Wheat straw significantly reduced soil bulk density and increased porosity. Soil organic matter and available soil nutrient content were the most suitable for application of chicken manure. Appropriate amount of crop straw could improve soil available alkali-available nitrogen and available potassium content to a certain extent. However, The available soil nutrient content of the treated straw was lower than that of the manure application.
