中文摘要:

在甘肃省酒泉市东洞乡日光节能温室内，采用田间试验方法，开展了有机碳生态肥配方筛选及对温室土壤理化性质和番茄效益影响的研究。结果表明，有机碳生态肥原料间的效应是：畜禽粪便组合肥（R＝55.12）＞废渣组合肥（R＝51.44）＞聚丙烯酰胺（R＝38.19），有机碳生态肥配方组合比例为m（畜禽粪便组合肥）∶m（废渣组合肥）∶m（聚丙烯酰胺）＝0.3995∶0.5993∶0.0012。有机碳生态肥施用量与温室土壤容重和pH值呈负相关，与孔隙度、团聚体、蓄水量、有机质、速效氮磷钾和番茄产量呈正相关。有机碳生态肥施用量为79.65t/hm2时经济效益最佳，番茄理论产量为62.01t/hm2，统计分析结果与田间施用有机碳生态肥80t/hm2基本吻合。

Abstract: In the solar energy-saving greenhouse in Dongdong town, Jiuquan city, Gansu province, a fi eld experiment was carried out to screen the formula of organic carbon ecological fertilizer and study its effects on the physical and chemical properties of greenhouse soil and tomato benefi ts. The results showed that the effect order of organic carbon ecological fertilizer was poultry excrement group (R=55.12) > residue group (R=51.44) > polyacrylamide (R=38.19), and the mass ratio of organic carbon ecological fertilizer for poultry excrement group, residue group and polyacrylamide was 0.399 5∶0.599 3∶0.001 2. The application amount of organic carbon ecological fertilizer was negatively correlated with soil bulk density and pH value, and positively correlated with porosity, aggregates, water storage, organic matter, available nitrogen, phosphorus, potassium and tomato yield. The optimal application amount of organic carbon ecological fertilizer was 79.65 t/hm2, and the theoretical yield of tomato was 62.01 t/hm2. The results of statistical analysis were basically consistent with the application amount of 80 t/hm2 for organic carbon ecological fertilizer in the fi eld experiment.
