生活垃圾堆肥对花生和猕猴桃生产品质的影响及其改土效果

EFFECTS OF GARBAGE COMPOST ON THE OUTPUT AND QUALITY OF PEANUT AND ACTINIDIA CHINENSIS AND ON SOIL IMPROVEMENT

研究了在红壤地区垃圾堆肥的肥效及改土效果。田间试验结果表明，施用垃圾堆肥４５～９０ｔ／ｈｍ２，猕猴桃鲜果增产５９．２％～３３２．３５％；花生增产１６．２％～２１．６％。猕猴桃鲜果维生素Ｃ含量提高２９．８７％～３５．１２％；总糖由４３．４ｇ／ｋｇ增加到８０．４８／ｋｇ；重金属元素Ｃｕ、Ｃｒ、Ｐｂ、Ｃｄ的含量基本上近似对照，与此同时，垃圾堆肥使土壤中对植物根系具毒害作用的交换性Ａｌ由１２．６６ｍｏｌ／ｋｇ降为０．３２ｍｏｌ／ｋｇ．土壤容重由原来的１．３～１．２７ｇ／ｃｍ３降为１．１１～１．１０ｇ／ｍ３；田间持水量由１５．８９％提高到１９．０４％；总孔隙度由５２．６％增加到５６．５％；土壤（ｍ／ｇ）微生物的总菌数由０．９７×１０６／ｇ增加到２２．５×１０６／ｇ。─增产极显著。Ｎｏｔｅ：ｎ＝１１，Ｌ．Ｓ．Ｄ．ｔｅｓｔ，＊─Ｓｉｇｎｉｆｉｃａｎｃｅｏｆｐｒｏｄｕｃｔｉｏｎｉｎｃｒｅｍｅｎｔ─Ｇｒｅａｔｓｉｇｎｉｆｉｃａｎｃｅｏｆｐｒｏｄｕｃｔｉｏｎｉｎｃｒｅｍｅｎｔ表３垃圾肥施用对花生产量的影响（％）Ｔａｂｌｅ３Ｅｆｆｅｃｔｏｆｃｏｍｐｏｓｔｄｏｓａｇｅｏｎｐｒｏｄｕｃｔｉｏｎｏｆｐｅａｎｕｔ（％）施用垃圾堆肥的猕猴?

Garbage compost was studied for its fertilizer effeciency and soil improvement in red soil region. The results obtained from field tests indicated; Production of fresh fruit of Actinulia chinensis was increased by 59.2%～332. 35% and peanut by 1 6. 2% ～ 1. 6%. when 45～ 90 ton of garbage compost was applied per hectare; vitamin C in fresh fruit of A. chinensis was increased by 29. 87 %～35. 42 %; total sugar from 43.4g/kg to 80. 4g/kg; the contents of heavy metal elements. including Cu. Cd, Pb and Cr. were similar to CK.Garbage compost could be used not only as a fertilizer for crops. but also to raise pH value of soil and remove toxic action of Al ion on plant root. Exchangeable Al was dropped from 12. 66 mol/kg to 6.32 mol/kg ; bulk density of soil from 1.3～ 1. 27t/m3 to 1. 1 1 ～ 1. 10t/m3; field capacity was increased from 1 5. 89% to 19.04 % and total porosity from 52. 6% to 56. 5%.
