Abstract: [Objective] The fruits and melons produced in Xinjiang enjoy great prestige all over our country.The fruit tree planting area is about one-third of the total arable land in this region.There is more than six hundred thousand hectare faming land which needs to be efficiently utilized in the fruit-bearing forest.Peanut interplanting with the fruit trees is one of the effective ways to make use of the cultivated land.[Method]Data gotten from the test of the peanut variety Huayu 31 planted under walnut trees were analyzed by using statistical software DPS and regularity and tendency of 8 traits expression were analyzed when peanuts had been planted in different spans from the trunk of the walnut trees.[Result]The results of analysis showed that there was difference among the 8 traits when peanuts were planted in different spans and the variable coefficient was 3.16;-47.60; and the variation of the yield per plant was the largest.The bigger of phenotypic values of 5 traits,the larger span from the trunk was,the more significant correlation would be.[Conclusion]With the farther distance from the trunk,phenotypic values of most of the traits will increase accordingly,among which,the increase of the yield per plant was the most obvious.Peanut should be planted in suitable place from trunks under fruit trees and the type of fruit-bearing forest should be chosen carefully and row spacing of fruit trees should be wide enough when peanuts are interplanted with them.

摘要： [目的]新疆瓜果誉满全国,林果业面积占到全区总耕地面积的三分之一左右,林间有60×104 hm2的耕地有待高效利用.研究套播种植花生将使该部分耕地得到有效利用.[方法]应用花生品种花育31号在26年生核桃树下种植的试验数据,使用dps统计分析软件,对花生8个性状进行比较分析,研究在距树干不同距离种植时,花生性状表现变化的规律和趋势.[结果]花生在距树干不同距离种植时,8个性状的表现存在差异,其变异系数在3.16;～47.60;,单株产量的变异幅度最大.研究的8个性状中,5个性状表现值随着距树干距离的变远而增加,相关性达到极显著,其中单株产量表现最为明显.[结论]随着距树干距离越远,花生多数性状表现数值会相应增加.其中单株产量的增加最为明显.在核桃等果林间套播种植花生时,花生的种植应当距离树干有适当的距离.在花生与相应的核桃间套种植时,核桃林行距类型的选择要适当.
