摘 要:
2005～2006年在广西隆安县的屏山、古潭、那桐3个乡镇设置标准地，对嫁接3～4年龄板栗林分别施用不同施肥量的含稀土有机无机复混肥（以下简称：稀土有机复混肥）及不含稀土有机复混肥（对照）。结果表明：（1）施用稀土有机复混肥的年均板栗果实产量为1442．2～4918．3kg／hm^2，平均比对照提高42．77％；（2）施用稀土有机复混肥的板栗果实淀粉、总糖及蛋白质平均含量依次为33．99％，6．84％，3．80％，分别比对照提高2．17％，1．67％，2．42％；（3）板栗叶片叶绿素平均总含量为7．91g／cm^2，比对照6．47g／cm^2平均提高22．26％；（4）施用稀土有机复混肥的年均板栗收入为11790．5元／hm^2，比对照7705．6元／hm^2增加经济收入60．73％；（5）除抽枝生长和结果状况外，所试验项目均以1125kg／hm^2稀土有机复混肥施肥量的各项指标为最佳。试验也表明：果园土壤施用稀土有机复混肥能明显提高板栗对病害的抵抗力，增强板栗树势，其中以施用1687．5kg／hm^2稀土有机复混肥施肥量的植株抗病害能力最强。[著者文摘]

Abstract:
To understand the effect of rare-earth on the quantity and quality of chestnut after grafting 3 -4 years, we established experimental site in Pingshan, Gutan, Natong towns in Longan, Guangxi. Results showed as following： （1） The yield of chestnut by using organic-inorganic mix fertilizer including rare-earth varied from 1 442.2 kg/hm^2 to 4 918.3 kg/hm^2, and increased by 42.77% on average, compared to the control treatment; （2）The average contents of aleurone, total sugar, protein in chestnut using organic-inorganic mix fertilizer including rare-earth were 33.99% , 6. 84% and 3. 80% respectively, which were improved respectively 2. 17%, 1.67% and 2.42% on average compared to the control; （3）Compared to that of the control （6.46 g/cm^2）, the average total content of chlorophyll in chestnut leafs of using organic-inorganic mix fertilizer including rare-earth （7.91 g/cm^2） increased by 22.26% ; （4）Annual average income of chestnut by using organic-inorganic mix fertilizer including rare-earth was 11 790.5 RMB/hm^2, which increased by 60.73% compared to the control （7 705.6 RMB/hm^2） ; （5） In addition to the traits of branch and fruitage, the results of tested items showed that 1 125 kg/ hm^2 was the best degree of using organic-inorganic mix fertilizer in chestnut garden. Additionally, it was obvious to improve the resistance to disease and to strengthen the growth by using organic-inorganic mix fertilizer in chestnut garden, and the resistance to disease in the treatment with 1 687.5 kg/hm^2 was the highest.[著者文摘]
