文山州有八角成林十万余亩,常年产量二百至三百万斤,平均亩产仅二三十斤。单产低的原因主要是老林比例大,不施肥。为了迅速提高八角老林的产量,文山州八角科研所从1983年开始进行施肥试验,结果表明,秋后施肥的老龄八角树有延寿、增产等收效。 1.投资小,收效大,见效快。根据多点试验结果,每株树一般施肥一斤左右,秋后能增收二至五斤干八角,即一株树春天收入二角五分钱,秋后即可增收七元左右,群众说这是“一本万利”的事。
Wenshan Prefecture has more than 100,000 acres of aniseed forest, perennial output of 200 to 3000000 pounds, the average yield of only twenty or thirty pounds. The main reason for the low yield is mainly the large proportion of old forests, no fertilization. In order to rapidly increase the yield of the plantation of the aniseed, the research institute at Wenshan Prefecture, including the Bajiao Science Research Institute, started the fertilizer experiment in 1983 and the results showed that the aged plantation Octagonal tree fertilized in the autumn had the effects of prolonging their life and yield increasing. 1. Small investment, big effect, quick. According to the results of the multi-point test, each tree generally fertilizes about a pound. After the autumn, it can raise two to five pounds of dried star anise. That is, one tree can earn about five cents per square meter of income in the spring and about seven yuan in autumn. Is “a profit” thing.
