Abstract:
Taking Juglans regia ‘Wen185’ as the research object in the Southern Xinjiang Basin,based on ‘3414’ spraying fertilizer effect field experiment,the effects of spraying compound fertilizer by N(urea),B(boric acid),and S(sugar)at the full-blossom period were tested to provide a scientific basis for spraying fertilizers management of J.regia ‘Wen185’.The results showed that the denary logarithm of fruit setting rate(q) of J.regia ‘Wen185’was not significantly correlated(P>0.05)with the spraying concentration of S(sugar),but it had a highly significant(P<0.01)linear correlation with the spraying concentration of N(urea)and B(boric acid)and interaction between them(B×N).There were positive effects on the fruit setting rate of J.regia ‘Wen185’ while the spraying concentration of N(46% of nitrogen)was less than 5.928 6 g?L-1 and the spraying concentration of B(17.49% of boron)was less than 3.857 1 g?L-1 at the full-blossom period of female flowers.In the Southern Xinjiang Basin at the full-blossom period of female flowers,sprayed suitable concentration of B and N could increase the fruit setting rate of J.regia ‘Wen185’.
