养殖池塘底泥的营养及其对菠菜生产力的影响
Nutrients of Bottom Mud in Culture Pond and Its Effects on the Productivity of Spinacia oleracea L.
摘要
Abstract
The yield of bottom bud in culture pond in Datong and Yuncheng of Shanxi Province was measured. And the contents of nutrient salt in the bottom bud and its surrounding soil were compared. Finally the productivity of Spinacia oleracea L. in bottom bud and its surrounding soil was studied. The results showed that the sediment amounts of bottom bud in the ponds of Datong and Yuncheng were 19.18 and 19.98 kg/m2 respectively. They were both higher, but there was little difference. The results of nutrient salt in the bottom mud and its surrounding soil of pond showed that the content of nutrient salt in the bottom mud of pond was obviously higher than that in the surrounding soil of pond. And the content of nutrient salts in test materials obviously decreased after planting S. oleracea. The productivity of S. oleracea in test group and control group were higher than that in the surrounding soil of pond, but there was little difference. Therefore the surrounding soil of pond could also be used for planting and the bottom mud in test group and control group could be used in the improvement of low-fertility soil.关键词
