[Objectives]This study was conducted to explore the treatment methods of amino acid selenium fertilizer suitable for increasing the selenium content of mangoes and improving the quality of mangoes,so as to provide a theoretical basis for the production of selenium-enriched mangoes.[Methods]With Tainong mango as a test material,the amino acid selenium foliar fertilizer was applied by eight treatment methods to investigate the changes of selenium,soluble solid,vitamin C,and titratable acid contents in mango flesh and peel.[Results]Spraying amino acid selenium foliar fertilizer increased the selenium content of mango *** selenium contents of the treatment groups T2,T3,T4 and T5 reached the selenium-enriched standard,and the T2 treatment group had the highest selenium content(0.020 mg/kg).The selenium contents in the peel of all treatment groups were greater than the corresponding selenium content in the *** for T1,the vitamin C contents of other treatment groups sprayed with amino acid selenium fertilizer increased compared with the control,and that of the T2 treatment group increased significantly(P<0.05).Compared with the control,the soluble solids of the treatment groups sprayed with amino acid selenium fertilizer once also *** treatment method of spraying amino acid selenium fertilizer with a dosage of 12000 ml/hm2 once(T2)achieved the best effect of increasing the selenium content and improving the quality of mangoes.[Conclusions]This study provides a scientific basis for increasing the selenium content of mangoes and improving the current situation of insufficient selenium intake.

Investigation of Habitats and Causes of Population Decline of Euonymus sanguineus in Tibet

Asian Agricultural Research 2018年第4期10卷 77-83页

Tibet is one of the core distribution areas of the Chinese endemic plant Euonymus sanguineus,but the population decline is obvious. In order to protect and develop the plant resources in Tibet rationally,the ecological environment and growth conditions in Milin County,Nyingchi City,Tibet were investigated by means of sampling method in order to provide the theoretical basis for the protection,introduction,breeding and cultivation of E. sanguineus. The results were as follows:( i) The population quantity of E. sanguineus was too small and the survival area was too small,which seriously affected the interspecific mating,seed development and regeneration,and greatly reduced the genetic diversity within the population;( ii) The dry and hot river valley climate and human and animal activities inhibited the seed germination and seedling growth of E. sanguineus,resulting in very low survival rate of seedlings,and hindering the population expansion of E. sanguineus;( iii) The distribution area is located in the Yarlung Tsangpo river valley,and the natural habitat fragmentation has affected the interspecific gene exchange,resulting in the low seed bearing capacity and germination rate of E. sanguineus,which is the direct cause of the population decline of E. sanguineus;( iv) The litterfall of E. sanguineus had autotoxicity,which inhibited the growth of seedlings under the forest,caused slow natural regeneration of the population,and then caused the population of E. sanguineus to be unable to spread and develop.
