摘要
经过１９９０～１９９１年的调查：省内火棘有４种类型，全省鲜果年总产量在２５００万公斤上以，各县均有分布但产量相差很大，高的达１００万公斤，低的仅为１万公斤。对火棘生长发育和分布有明显影响的是温度、光照和海拔。省内从海拔２５０～２５００ｍ都有分布，而在８００～２４００ｍ之间是其生态最适带。果实成熟期在８月中旬至１２月上旬。
The investigation results in 1 990-1991 were summarized as follows.There are 4 kinds of Pyracantha fortuneana in Guizhou province,Annual total yield of its fresh fruit is above 2 5 million kilogram. H is distributed in every county with widely different output.The highest yield in a county can be 1 million kilogram and the lowest yield only 10 thousand kilogram. Its growth and distribution could be influenced obviously by temperature,sunlight ,and altitude,it is distrbuted in the areas from Alt.250 to Alt .2500 m with most suitable area within 800-2400m,The mature period is from middle ten days of August to first ten days of December.
