关于腰果最适株行距问题的报道不多,为此在南部的纳饮瓜(Nachingwea)布置了一个株行距试验。1962年诺思伍德曾在坦桑尼亚南部腰果植区进行了调查。植区11月至次年4月降雨量大部分不到40英寸(1,016毫米),而5—10月则为一漫长的旱季。腰果树在7至11月旱季开花、结果,那时所需水分就必须靠土壤中贮藏的水供应。因此选择株行距时,要特别考虑土壤的可用水分。
There have been few reports on the optimal row spacing of cashews, and for this purpose a row spacing test was arranged in Nachingwea, in the south. In 1962 Northwood conducted a survey in the cashew region of southern Tanzania. Most of the rainfall from November to April is less than 40 inches (1,016 mm), while May-October is a long dry season. Cashew trees flowering in the dry season between July and November, and as a result, the water needed then has to be supplied by the water stored in the soil. Therefore, the choice of row spacing, we must give special consideration to soil available water.
