摘　　要：对 7a生锥栗果用林土壤穴施复合肥生长效应进行研究 ,结果表明 :土壤穴施复合肥 ,确保锥栗生长旺盛期有机物合成和碳水化合物合成所需营养元素的供应 ,从而在一定程度上促进锥栗的营养生长、生殖生长和果实的生长发育。其中以施复合肥 1 .5 kg/株较为经济而有效 ,与不施肥对照的相比 ,叶片中的蛋白质含量提高 32 .81 % ,叶绿素含量提高 2 2 .0 9% ,果枝数增多 2 3.0 8% ,球果数增多 33.84% ,坚果质量提高 2 8.81 % ,坚果增大 6.5 8% ,单株坚果产量提高 72 .44%。Investigation on the growth effect of applying complex fertilizer in 7 years old chestnut plantation,at Liandi village,Fangdao town,Jian'ou city,Fujian province showed that applying the fertilizer in holes could accelerate the alimentation growth,the procreation growth and the fruit up growth of the chestnut to a certain extent,the fruit was big and saturation.Because it insured the purveying of the requisite nutrient synthesizing of the organic matter and the carbohydrate.It is the economic and effective disposal that applying complex fertilizer 1.5 kg per tree in the soil hole.The protein content was as high as 32.81%,the chlorophyll content 22.09%,the fructifying stick quantity increased by 23.08%,the fruit quantity 33.84%,the nut weight accretion 28.81%,the nut accretion 6.58%,the nut yield of the individual plant increased 72.44%,comparing to the control.
