菠萝是我县的主要水果之一,七十年代以来栽培面积和产量都增长很快。1982年全县种植面积为66000多亩,总产达43万多担,创建国以来的最高记录。面积比1970年增长70.04％,总产增加近3倍。种植面积以前山、曲界两个公社最大,产量分别为14和13万担。菠萝占经济作物总收入的17.10％,徐闻县的果农对菠萝生产有极丰富的经验;现择其主要者介绍于下。 (一)采用大苗种植,小苗培育过去,我县的果农普遍忽视对菠萝种苗的选择和分级,大小苗混合种植,从定植到第一造果收获往往要24—36个月。由于种苗未经分级种植,结果不一致,造成田间管理困难,并有大苗压小苗,引起部分株苗死亡而减产。种苗经分级后,选择大苗定植,植株间生长较平衡,管理方便,结果齐一,产量高且稳定。小苗经苗圃培育后定植,只要12个月就可以开花结果(表1)。
Pineapple is one of the main fruits in our county. Since the 1970s, cultivation area and output have all increased rapidly. In 1982 the county planted an area of 66000 mu, with a total output of more than 430,000, the highest since the founding of the country. The area increased by 70.04% over 1970 and the total output increased by nearly 3 times. Before planting acreage, Qu commune the largest two communes, the output was 14 and 13 million Tam. Pineapple accounted for 17.10% of the total cash crops, Xuwen County, the farmers of pineapple production has a very rich experience; now choose its main introduction. (A) the use of large seedlings planted in the past, nursery farmers in our county generally ignore the selection and grading of pineapple seedlings, seedling size mixed planting, harvesting from planting to the first often have to 24-36 months. As the seedlings are not graded, the results are inconsistent, resulting in field management difficulties, and a large seedling pressure seedlings, causing some seedlings die and cut. Seed grading, the choice of seedlings colonization, plant growth more balanced, easy management, the results of a homogeneous, high yield and stability. Seedlings nursery nursery colonization, as long as 12 months to flowering (Table 1).
