我国菠萝主要栽植于丘陵地,栽培面积约6万hm~2(公顷),总产量48万t(吨),平均每公顷产量7 545kg左右,不计国营农场,乡镇菠萝平均每公顷产量还不到6 750kg。为此,国家科委下达“菠萝栽培技术开发利用”星火项目给广西。我们根据项目要求在广西防城县组织实施,经过4a(年)圆满完成了项目开发任务,现总结报道如下。1 开发规模在防城县实际开发规模为1 608.86hm~2,占全县菠萝栽培总面积的89.56％,占广西乡镇菠萝栽培面积的20.42％。其中高产示范面积有24.33hm~2,技术开发面积为1032 .53hm~2,技术推广面积552hm~2。
Our pineapple is mainly planted in the hilly land, the cultivation area is about 60,000 hm ~ 2 (hectare), the total output is 480,000 t (tons), the average output per hectare is about 7,545kg. Excluding the state-owned farms, the average output of the township pineapple is less than 6 750kg. To this end, the State Science and Technology Commission issued “pineapple cultivation technology development and utilization of” Spark project to Guangxi. According to the requirements of the project, we organized and implemented the project in Fangcheng County, Guangxi Province. After 4a (years), we successfully completed the project development task and are summarized as follows. 1 The actual scale of development in Fangcheng County is 1 608.86hm ~ 2, accounting for 89.56% of the total area of pineapple cultivation in the county and 20.42% of the cultivation area of pineapple in Guangxi. Among them, the demonstration area of high yield is 24.33hm ~ 2, the area of technological development is 1032.53hm ~ 2, and the area of technology promotion is 552hm ~ 2.
