养殖污水和清水混灌对小麦苗期生长及土壤速效养分含量的影响
Effects of Livestock Farm Wastewater and Clear Water Combined Irrigation on Wheat Seedling Growth and Soil Available Nutrient Content
摘要
Abstract
The effects of livestock farm wastewater and clear water combined irrigation on the growth of wheat seedlings and the content of soil available nutrients were studied by pot irrigation experiment. The results indicated that the wheat germination time increased with the increase in the irrigation quantity of livestock farm wastewater. The irrigation of suitable quantity (200 ml/kg) of livestock farm wastewater could markedly enhance the germination rate of wheat, and increase the weight of overground dry matter of wheat. The contents of salinity, alkali - hydrolyzable nitrogen, available phosphorus and available potassium increased in the whole a-long with the increase of the livestock farm wastewater irrigation quantity, and they mainly run up to the soil layer from 0 to 5 cm. The salinity, alkali -hydrolyzable nitrogen and available potassium in the soil had a obvious downward leaching trend.关键词
