摘　　要：研究了5年生优一杏扁园地面覆盖地布、秸秆和地布+秸秆对土壤温湿度、养分和杏扁新梢生长的影响。结果表明:3种覆盖可以稳定5、20 cm土层的土壤温度;提高了0~20 cm土层的土壤含水量,以地布+秸秆覆盖处理效果最好;除Ca和Mg外,土壤中N、P、K等矿质元素含量均显著高于对照,以地布+秸秆覆盖处理最佳。3种覆盖处理杏扁新梢长度和粗度均显著提高,表现为地布+秸秆覆盖>地布覆盖>秸秆覆盖>对照。We explored the effects of different mulching measures on soil nutrients and shoot growth of 5 years old‘Youyi’Prunus armeniaca L..And the the experimental treatment was included in black plastic mulch,straw mulch,and black plastic+straw mulch,we detected the soil temperature and humidity,soil nutrients,and so on.The results was showed that all the three treatments kept the soil layer of 5 cm and 20 cm temperature,and increased the soil water content at the 0~20 cm layer.Compared with no mulching,the best treatment was black plastic+straw mulch,which enhanced the content of N,P,K and other elements,excluded Ca and Mg.The shoot length and stem diameter of the three mulching treatments were all significantly increased,black plastic+straw mulching>black plastic mulching>straw mulching>control.
