菠萝是多年生草本果树,种植2～3年后,自然结果率达到60～80％。在闽南金三角地带,主要集中在4～5月开花,称正造花,成熟于7～9月称夏果,小量陆续开花于6～9月,称二、三造花,成熟于11月至翌年3月,称秋、冬果。4月份以后,自然开花成熟果实较少,主要是靠人工控制诱导开花结果,成熟于4～6月称春果,以后为夏果代替。 人工控制菠萝开花结果新技术的应用,促使了菠萝提早结果,提高结果率达到95％以上。果实品质优良,增加单位面积产量,延长菠萝采收期。解决了菠萝果实的周年供应,为市场和罐头加工调整季节和提供原料,增加春季菠萝生产,果农收入增多。 Pineapple is a perennial herb tree, planting 2 to 3 years, the natural result rate of 60 to 80%. In the Golden Triangle area in southern Fujian, the main flowering occurs from April to May, which means that flowers are being made and ripening is called summer fruit from July to September. A small amount of flowers flowered from June to September in succession, saying that flowers of two or three were planted and matured from November to the following year March, said autumn and winter fruit. After April, less natural flowering mature fruit, mainly by artificial control induced flowering, mature in April to June called spring fruit, after the summer fruit instead. Artificial control pineapple flowering results of the application of new technologies, prompting the pineapple early results, improve the results of more than 95%. The fruit quality is good, the output per unit area is increased, and the harvest time of pineapple is prolonged. Solve the annual supply of pineapple fruit, for the market and canned season to adjust and provide raw materials to increase spring pineapple production, fruit farmers income increased.
