Effect of Sowing Rate,Fertilizer Amount and Light on Yield of Cichorum glandulosum Boiss. Et Huet.

摘要

[Objectives]This study aimed to investigate the effect of sowing rate,fertilizer amount and light on yield of Cichorium glandulosum Boiss.et Huet.[Methods]The Latin square design was adopted to investigate the effect of sowing rate+fertilizer amount,sowing rate+light on root and seed yield of C.glandulosum Boiss.et Huet.The changes in the seed and root yield of C.glandulosum Boiss.et Huet.under the influence of sowing rate,N application rate and light were compared and analyzed.[Results]In Moyu,Hotan and similar areas,the suitable sowing rate of C.glandulosum Boiss.et Huet.was 4.5-15.0 kg/ha.Without applying fertilizer,if the main purpose is to harvest the roots,the sowing rate of C.glandulosum Boiss.et Huet.is recommended to be 7.5-15.0 kg/ha;and if the main purpose is to harvest the seeds,the sowing rate is recommended to be 4.5-7.5 kg/ha.Shading will affect the root and seed yield.At the fertilizer amount of 450 kg/ha,the optimal sowing rate of C.glandulosum Boiss.et Huet.is 4.5 kg/ha.[Conclusions]This study provides a certain reference basis for artificial cultivation of C.glandulosum Boiss.et Huet.
