Effects of residue coverage on the characteristics of soil carbon pools in orchards     

Deying Zhao  Cungang Cheng  Man Jiang  Guodong Du 《Archives of Agronomy and Soil Science》2017,63(6):771-783

The effects of organic waste coverage on the quality of soil carbon (C) pools in orchards remain unclear. In this study, we performed a 3-year experiment in an 8-year-old Fuji apple orchard to investigate the effects of inter-row weed growing/inner-row pruning residue coverage (PRC), weed coverage (WC), and inter-row weed growing/inner-row non-coverage (used as a control) on the contents of soil water, available nitrogen, phosphorus, and potassium, organic C components, glomalin-related soil protein (GRSP), soil microbial biomass C, and the number of microorganisms at different soil depths. PRC increased the percentage of readily oxidizable C (ROC), whereas WC improved the percentage of soil humin (HM). Thus, PRC enhanced SOC activity, whereas WC promoted SOC stability. Moreover, soil water, available nitrogen, phosphorus, and potassium contents increased in WC in 0–20-cm soil depths as compared to that in PRC, and the correlation between total GRSP (T-GRSP) and HM (r = 0.92) was higher than that between T-GRSP and ROC (r = 0.79). Therefore, T-GRSP is important in HM formation and maintaining stability of C pools. Overall, these results improve our understanding of the positive effect of organic waste coverage on soil internal C cycling and energy flow within an orchard ecosystem.  相似文献   

Effect of pruning intensity on peach yield and fruit quality   总被引：1，自引：0，他引：1  

Manoj Kumar  Vidyawati RawatJ.M.S. Rawat  Y.K. Tomar 《Scientia Horticulturae》2010

Light, medium and heavy pruning treatments were used with one unpruned as check (control) in Flordasun, Flordaking and Saharanpur Prabhat peaches. Fruit yield decreased with the increase in severity of pruning in Flordaking and Saharanpur Prabhat peaches, whereas, medium pruning treatment gave highest yield in Flordasun peach. Pulp weight, stone weight, pulp-stone ratio, ascorbic acid, sugar acid ratio and moisture content were not affected by pruning levels. However, fruit weight, size, TSS, sugar and acid content were significantly increased by pruning in Flordasun peach. Almost all the physico-chemical characters were significantly affected by pruning in Flordaking and Saharanpur Prabhat peaches, in which medium and heavy pruning treatments performed better, respectively.  相似文献

为了探求不同栽培整枝方式对日光温室冬春茬厚皮甜瓜熟性、产量、品质和商品性状的影响,进行了4种栽培整枝方式比较试验。结果表明:甜瓜采收期以爬地栽培单蔓整枝方式最早,比吊蔓栽培单蔓整枝方式和爬地栽培双蔓整枝方式早3d,比对照爬地栽培3蔓整枝方式早8d。单果质量、总产量、可溶性固形物含量均以吊蔓栽培单蔓整枝方式最高。吊蔓单蔓方式单果质量(755g)高出对照335g;667m2总产量达2926kg,比对照增产56.6%;中心可溶性固形物17.5%,高出对照2个百分点;且甜瓜果面光洁,果色均匀,果形周正,口感风味好,商品性状优良。据此,建议冬春茬厚皮甜瓜保护地栽培宜推广吊蔓单蔓整枝栽培方式,以取得优质高产高效。  相似文献

冬芽管理是猕猴桃树体管理的重要技术环节。适宜的高质量冬芽保留,可较准确预测果实数量,提高果实大小一致性。本研究在江西省猕猴桃主栽区奉新县的赤岸镇山口果园,以10年生“金魁”猕猴桃为研究对象,研究冬芽保留数量对果实生产的影响。试验设置4个处理,每个处理以贝为单位（bay, 四根水泥柱围成的面积,18 m2）,每处理冬芽保留量处理1约为400个、处理2约为450个、处理3约为500个、处理4约为550个,每处理3次重复。结果表明：1）4个处理的冬芽保留量不影响新梢萌发量;2）处理1成花量显著大于其他处理;处理1和2,花芽/冬芽显著大于处理3和4;3）单位新梢上成花量,处理2显著大于其他3个处理;4）4个处理中,挂果量和产量没有显著差异,冬芽保留处理1的果实更大,更均匀,小果和超大果比例更小,即单位面积能生产出更多符合市场需求的优质商品果。综合分析,在试验区立地条件和现有管理水平下,冬芽保留量在约450个,有利于提高猕猴桃种植者的经济效益。  相似文献   

Mineralization of nitrogen from decomposing leaves of multipurpose trees as affected by their chemical composition     

P. L. Mafongoya  P. K. R. Nair  B. H. Dzowela 《Biology and Fertility of Soils》1998,27(2):143-148

 Nitrogen release patterns from seven leguminous trees were determined from 8-week laboratory incubations. The quantities of extractable NH₄ ⁺-N and NO₃ ^– released to the soil to which the leaves had been applied was determined at weekly intervals and was related to the initial N, polyphenol, and lignin concentration of the leaves. Cumulative N mineralized was not correlated to initial N, soluble polyphenol and insoluble tannin concentrations, but was correlated to lignin and neutral detergent fibre N (NDF-N) concentrations. The ratios of NDF-N : N (r=0.68 at P<0.05), soluble polyphenol : N (r=0.70 at P<0.05) and (lignin+polyphenol) : N (r=0.75 at P<0.05) were negatively correlated with N release. Total polyphenol content was not a useful predictor of N release, but the reactivity of the polyphenols as measured by their protein-binding capacity can be a useful predictor. In addition to measuring the concentration of polyphenols, their reactivity with proteins must be measured, in order to assess their role in regulating N release. The (lignin+polyphenol) : N ratio could be used to screen leguminous tree leaves for their potential to release N in short-term experiments. This would allow for rapid screening of a large number of trees without detailed and expensive field experimentation. Received: 30 June 1997  相似文献
