果利达植物调节剂对红江橙经济性状影响初探

The Preliminary Test Studies of the GuoLiDa Plant Growth Regulator Applied to Hongjiang Orange

应用湛江师范学院研制的果利达植物生长调节剂 ,对红江橙的增产增质效果进行了初步应用试验研究 ,结果表明喷施果利达具有以下功效 :( 1 )可以提高红江橙平均单果重 ,其中以 3# 药剂效果最显著 ,盛花期施用 4 0、2 0、1 0、5mg/L ,平均单果重比对照提高4 3.77% ,4 3.1 1 % ,36 .5 2 % ,32 .91 % ,幼果期比花期喷药对果实单果重的提高更明显 ;( 2 )可以提高果实可溶性固形物的百分含量 ,提高了果实的品质 ;( 3)

The GaoLiDa plant growth regulator (GLD)prepared by Zhanjiang normal college was applied to Hongjiang Orange for yields increasing and quality improving effect. The results showed that the GLD had following functions: (1)Increase the average weight of per fruit and the effect of GLD 3 # is most evident, the average per fruit weight increase 43.77%?43.11%?36.52%?32.91% by using GLD3 # 40?20?10?5mg/L during florescene against of not using GLD, increasing effect of single fruit weight was more evident if the GLD was sprayed during the young fruit period; (2)Increase the percentage content of soluble solid.(3)Improve the nutritional growth of the orange.
