中文摘要:
      通过田间试验研究了化肥施用量减半条件下,种植绿肥对宁杞5号枸杞果实产量和土壤养分含量的影响,试验包括化肥减半+配施有机肥(T1)、化肥减半+翻压油菜(T2)和全施化肥(CK)三个处理。结果显示:与CK相比,T1和T2处理分别使枸杞干果年产量显著增加24.1%和19.1%; 在秋果采收后,T1和T2处理分别使枸杞地土壤有机质、碱解氮、速效磷、速效钾含量较CK显著增加12.8%、13.2%、36.0%、28.2%和60.2%、23.1%、28.5%、57.9%。说明在化肥施用量减半条件下,配施有机肥或翻压油菜绿肥均可以提高枸杞地土壤养分含量,增加枸杞干果产量;而且在提高土壤养分含量方面,翻压绿肥油菜效果更为显著。枸杞行间套种油菜作为绿肥翻压,可以减少化肥施用量,也是提高枸杞产量和枸杞地土壤养分含量的重要技术措施。
英文摘要:
      A field experiment was conducted to study the effects of green manure on the fruit yields of Ningqi No. 5 wolfberry and soil nutrientstatus, under the condition of halving the amount of fertilizer, which included half chemical fertilizer with organic manure (T1), half chemical fertilizer spreading rapeseed straw manuring (T2), and chemical fertilizer only (CK) treatments. Results showed that, compared with CK, the dry fruit yield of T1 and T2 treatments was significant increased by 24.1% and 19.1%, respectively. Contents of soil organic matter, alkali hydrolysable N, available P, available K of T1 and T2 treatment significant increased by 12.8%, 13.2%, 36.0%, 28.2%, and 60.2%, 23.1%, 28.5%, 57.9%, respectively, at the end of autumn when fruits were harvested. These results indicated that, under the condition of halving the amount of fertilizer, both added organic manure and rapeseed straw manuring could increase the wolfberry fruit yield and the soil nutrient content, and the rapeseed straw manuring was more significant than added organic manure. Therefore, wolfberry interplanting with rapeseed as green manure not only reduced the chemical fertilizer application, but also increased the fruit yield and soil nutrient content of wolfberry.
