以玉米秸秆、土壤和鸡粪为基质,堆肥腐熟后用于日光温室栽培,研究不同氮肥施用量对人工营养基质的理化性质及其对番茄产量的影响。试验结果表明:施氮肥量为60.32kg hm-2的处理最佳,其基质的理化性质最好,番茄产量最高,为60520.49kg hm-2,比对照(土壤栽培)增产25.4%。另外,成本比常量氮肥施用量低。
Corn stalks, soil and chicken manure were used as substrates. Compost was used for cultivation in sunlight greenhouse. The physicochemical properties of artificial nutrient matrix and its effect on tomato yield were studied. The results showed that the treatment with 60.32kg hm-2 nitrogen fertilizer had the best physico-chemical properties. The highest yield of tomato was 60520.49kg hm-2, which was 25.4% higher than the control (soil culture). In addition, the cost is lower than the constant amount of nitrogen fertilizer.
