摘    要:通过小麦盆栽研究凹土对灌淤土养分含量及小麦生长和产量性状的影响.结果表明:施用凹土不影响土壤速效养分,但用量大于40 g/kg会降低碱解氮含量,使生物量、地上部生物量、穗长、孕小穗数、穗粒数和穗粒重下降,不孕小穗数增多;小于40 g/kg时不影响上述产量性状;千粒重随凹土用量的增大而增加,在80 g/kg时达到最大,增加13.01%.

关 键 词:凹土  灌淤土  养分含量  小麦

Abstract:Effects of attapulgite clay on nutrient content in irrigation-silted soil,wheat growth and yield components were studied by means of planting the wheat in a pot.Results showed that applying the attapulgite clay into the soil had no influence on its quick-acting nutrient.However,the N-content of the soil would decrease when the dose of attapulgite clay in soil was more than 40 g/kg.The biomass,above-ground biomass,spike length,spikelet number,grain number and grain weigh would be decreased while sterile spik...
Keywords:attapulgite clay  irrigation-silted soil  nutrient content  wheat
