生长调节剂TDS对锥栗生长调控效果的研究

Study on the Effect of Spraying TDS on the Chestnut Laminae

福建省建瓯市房道镇连地村 7年生锥栗果用林叶面喷施生长调节剂 TDS效应研究结果表明 :叶面喷施生长调节剂 TDS,可在一定程度上抑制锥栗的营养生长 ,极大地促进光合作用和代谢作用 ,多分化雌花 ,增加球果数 ,显著提高坚果产量 .在展叶盛期 ,用 5 .0 g/L的 TDS喷洒叶面 3次 (每星期喷 1次 ) ,效果较为显著 ,使当年生枝条的长度缩短 1 2 %、叶片的蛋白质含量提高 45 %、叶绿素含量提高 2 0 % ,冠幅体积球果产量提高 47% ,冠幅体积坚果产量提高 5 7% ,冠幅投影面积坚果产量提高 5 0 % ,冠幅外表面积坚果产量提高 60 % .

The results,investigated on the growth effect of insufflation growth regulator on the laminae in 7 year old chestnut plantation,at Liandi village,Fangdao town,Jian'ou city,Fujian province,showed that it could control alimentation growth on a certain extent,accelerate remarkably photosynthesis and metabolizing action,differentiate more female flower,add observably cone number,thereby enhance markedly nut yield,spraying growth regulator TDS on the laminae The effect was quite obvious, spraying continuously TDS 5 0 g/L on the chestnut laminae three time (once a week) It could shorten the branch length by 12%,advance the protein and chlorophyll content of the laminae 45% and 20%,increase the cone yield and the nut yield of the units tree crown volume by 47% and 57%,increase the nut yield of the units tree crown projection size and surface size by 50% and 60%
