Rates of greening in SHEN DONG Mineare ７０ percent ,but the harsh nature of the environment seriously affects the normal grow th of trees . This paper reports a studyon the effect of increasing grow th of Pinus tabulaeformi under the different fertilizer rates which will provide fertilizerrecommendations for forestation .Materials and methods The experimental area is located on ShenDong Mine in Inner Mongolia in the semiarid region of northChina . We selected ７ kinds of fertilizer treatments : , １( CK) , ２( urea ２００g) , ３ ( phosphate ammonium ５００g ) , ４ ( sheep manure２kg ) , ５( urea １００g , SSP ２００g and potassium chloride ５０g ) , ６( urea ２００g , SSP ２５０g and potassium chloride ５０g ) , and ７( sheepmanure ２kg , urea １００g , SSP ２００g and potassium chloride ５０g ) . The amount of fertilization above was for one tree . Therewere ５ trees per treatment and ９ replicates . Each treatment is radial arranged . Specific fertilization methods are as follows :first , chemical fertilizer , stiletto ６０ cm at each corner of tree well with Luoyang spade ; second , organic fertilizer , embedding itin ringy ditch or radial ditch , the depth of ditch ＞ ４０ cm . Fertilizers were applied in Autumn of ２００３ and Spring of ２００４ .Diameter of pinus was measured by vernier caliper at September of ２００３ ( １ m above of ground ) and signed , af ter that ,measuring the diameter and shoot grow th of Pinus at October of ２００４ and September of ２００５ .Results For shoot grow th , in ２００４ , only the third treatment had a significant effect . In ２００５ , the fif th treatment significantlyimproved the shoot grow th . For the diameter , there was no significant difference in ２００４ . In ２００５ , besides the third treatmentbeing lower than the control , all of the others were significantly higher . In general , the compound fertilizer had a better effectthan the single‐effect fertilizer . The result of ２００５ is better than ２００４ . The difference of diameter increment was higher thanthe difference of shoot grow th . The amount of shoot grow th in ２００５ was １ .４ times of ２００４ and the diameter increment is ２ .３times .Table 1 In f luence and v ariance analysis o f Pinus grow th amount under di f f erent f ertiliz er conditions in di f f erent yearsYear Grow th amountProbability( P)T reatment１st ２nd ３rd ４th ５th ６th ７th Average２００４ 垐Shoot grow th( cm) １９ k.４ １９ ?.９ １３  .８ １７ 邋.９ １８ 构.６ １７ 寣.８ １７ `.３ １７ .８Probability( P) ０ 沣.５９１５ ０ 晻.００５４倡倡 ０ 墘.１７１６ ０ 媼.６１ ０ 0.１３５７ ０  .０７０７Diameter( mm) ６ 倐５ (.８ ４ �.８ ５ 挝.７ ６ ⅱ.９ ５ u.７ ６ I.７ ５ .９Probability( P) ０ 沣.８６１３ ０ 抖.３４０１ ０ 墘.７６９３ ０ ].３６１２ ０ 0.７６９３ ０  .５０４５２００５ 垐Shoot grow th( cm) ２４ k.３ ２５ ?.６ ２２  .４ ２５ 邋.４ ２８ 构.６ ２４ 寣.１ ２５ `.８ ２５ .２Probability( P) ０ 沣.６２７１ ０ 抖.１３５９ ０ 墘.３８６５ ０ I.０１４５倡 ０ 0.８０９５ ０  .１１２４Diameter( mm) １２ k.６ １３ ?.８ １０  .８ １３ 邋.２ １４ 构.５ １４ 寣.４ １６ `.３ １３ .７Probability( P) ０ 骀.０１６倡 ０ ＃.０２５２倡 ０ v.０４０８倡 ０ <.００４３倡倡 ０  .００８２倡倡 ０ 沣.０００２倡倡Conclusions After fertilizer application , Pinus摧s grow th rate increased and the compound fertilizer had a better effect than thesingle one . An acceleration of was shown in the third year indicating a temporal effect , so , fertilizer could be applied earlier .Acknowledgement This work was funded by the １１th Five‐Year Technology Support Project ( ２００６BAD０３A０３０７ ;２００６BAD２６B０１０２)ReferencesChenHongjun ,LiYiquan ,YangChengdong .１９９８ .
