摘要
本研究经过连续3年川中丘陵区的乐至县孔雀乡马鞍山村蓬溪青花椒幼林地上套种黄豆、白菜、土豆,提高土壤含水量,增加土壤肥力,促进幼树生长研究。结果表明:(1)套种黄豆的土壤0~40 cm含水量旱季增加2. 48g·kg^(-1);套种土豆土壤0~40 cm含水量旱季增加2. 07 g·kg^(-1);套种白菜土壤0~40 cm含水量增加1. 52 g·kg^(-1)。(2)套种的土壤有机质比对照增加21. 39 mg·kg^(-1)~22. 78 mg·kg^(-1),土壤有效氮增100. 02 mg·kg^(-1)~110. 77 mg·kg^(-1),土壤有效磷增11. 29 mg·kg^(-1)~11. 46 mg·kg^(-1),土壤有效钾增加61. 4 mg·kg^(-1)~63. 6 mg·kg^(-1)。(3)套种黄豆、土豆、白菜对蓬溪青花椒树高、地径生长量有显著的促进作用,尤其套种黄豆的蓬溪青花椒幼树生长量最好,高、径生长为对照的1. 31倍和1. 85倍。
For 3 years in a row,a study was carried out by planting soy beans,cabbage,potatoes in young forest land of Zanthoxylum armatum ‘Pengxiqing’ in order to increase soil fertility,water utilization and the growth of young trees.The result showed that （1） the moisture content of 0~40 cm soil was increased by 2.48 g·kg -1 in dry seasons, where Soy beans were planted.The moisture content of 0～40 cm soil were increased by 2.07 g·kg -1 where potatoes were planted,and the moisture content of 0～40 cm soil was increased by 1.52 g·kg -1 where cabbages were planted.（2） The soil organic matter was increased by 21.39 mg·kg -1 ～22.78 mg·kg -1 ,the soil active nitrogen was increased by 100.02 mg·kg -1 ～110.77 mg·kg -1 ,the soil active phosphorus was increased by 11.29 mg·kg -1 ～11.46 mg·kg -1 ,and the soil effective potassium was increased by 61.4 mg·kg -1 ～63.6 mg·kg -1 ,as compared with the control group.（3） Planting soybeans,potatoes,and cabbages had a significant effect on the tree height and ground diameter of Z.armatum ‘Pengxiqing’.In particular,the young trees planted with soybeans grew the best,and the height and diameter growth were 1.31 times and 1.85 times of the control group respectively.
