Cereal cyst nematode (CCN) (Heterodera avenae) is a major root parasite of wheat throughout the world. A pot experiment was conducted in screen house in CCS Haryana Agricultural University, Hisar during 2016–2017 for studying the nutrient uptake by wheat plants infected with H. avenae. Urea, single super phosphate (SSP), Muriate of potash (MOP), and zinc sulfate (Zn SO4) were applied singly and in combinations, and compared with a control without fertilizers. H. avenae reduced the uptake of nutrients (nitrogen (N), phosphorous (P), potassium (K), and Zn) as compared to uninfested soil. Improved nutrients uptake was found in the treatment where all nutrients were applied in soil. Lesser uptake was recorded in the treatment where no nutrient was applied in soil. In the soil, more nutrients were recorded in infested soil as compared to uninfested soil and, nutrients were also more in soil in the treatments where individual nutrients were applied than their combined application.

燕麦杂种优势对小麦土壤中氮,磷,钾和锌吸收和转运的影响

谷物囊肿线虫(CCN)(Heterodera avenae)是全世界小麦的主要根寄生物。2016-2017年期间,在希萨尔CCS哈里亚纳邦农业大学的筛房进行了盆栽试验,以研究感染了燕麦的小麦植物对养分的吸收。将尿素,单一的过磷酸钙(SSP),钾肥(MOP)和硫酸锌(Zn SO 4)单独或组合施用,并与不施肥的对照进行比较。燕麦与未感染土壤相比,减少了养分(氮(N),磷(P),钾(K)和锌)的吸收。在将所有养分施用到土壤中的处理中,养分吸收得到改善。在土壤中未施用任何营养的处理中,记录的吸收较少。在土壤中,受侵染的土壤中记录的养分比未侵染的土壤更多,并且在施用单独养分的处理中土壤中的养分也比其联合施用的更多。
