Effects of Manure Applications on Tomato Yields and Soil Nitrogen and Phosphorus Accumulation in a Greenhouse Production System
摘要
Abstract
Based on international strategies of manure applications, a two-year experiment was conducted in a greenhouse production system to investigate the effects of different strategies of manure application on tomato yield and soil nitrogen(N)and phosphorus(P)accumulation. The treatments included control treatment(SN)(the traditional farmers′ manure application); P-based manure application(P); P-based manure plus wheat straw application(P+S);N-based manure application(N). Compared to the control(SN)treatment, different strategies of manure application increased tomato fruit yields, with no significant differences among the different strategies. The apparent N surplus was 1123, 1048, 1039 kg N·hm-2, and the apparent P surplus 219, 249, 226 kg P·hm-2 for P, P+S and N treatments, respectively. In 0~180 cm soil depth, soil inorganic N increased by 497, 480, 440 kg N·hm-2, and soil Olsen-P content increased by 28.4, 34.7, 31.0 mg P·kg-1 in P, P+S and N treatments, respectively. The preliminary results show that the accumulations of N and P in soils were greater under P-based and P-based+S treatments than under N-based treatment during the two-year experiment period.关键词
