菠萝(Ananas comosus)为热带多年生草本植物,是我国南方名果之一。其味香肉甜,营养丰富,鲜食和罐藏加工均可,在对外贸易中占有重要地位。 我省菠萝产地主要集中在闽南金三角地区。十几年来,种植面积不断扩大,但由于应用技术不当,粗耕浅种,水土流失严重,产量一直不高。针对生产中存在问题,我们深入生产基地,进行了多年的丰产栽培试验,促使菠萝产量不断提高,创造了亩产5000公斤的高产纪录。 几年来,我们采用了选种、地膜复盖、合理密植、激素处理、深翻改土、低沟种植等措施,进行综合性栽培试验,使370亩菠萝产量由1980年的亩产410公斤提高到1986年的亩产1400公斤,其中的15亩丰产栽培试验地平均亩产3522公斤,有一亩达到5200公斤。 Ananas comosus, a tropical perennial herb, is one of the most famous fruits in southern China. Its sweet and mellow taste, rich nutrition, fresh food and canning processing can occupy an important position in foreign trade. Pineapple origin in our province mainly concentrated in the Golden Triangle area in southern Fujian. Over the past decade or so, the area under cultivation has been constantly expanding. However, due to improper application of technology and heavy crude cultivation, soil erosion has been so severe that output has remained low. In view of the existing problems in production, we went to the production base for many years and conducted high-yielding cultivation experiments to promote the continuous production of pineapple and create a record high yield of 5,000 kg per mu. Over the past few years, we have adopted comprehensive measures such as seed selection, plastic film mulching, close and close planting, hormone treatment, deep soil amendment and low-ditch planting and comprehensive cultivation trials to increase the output of 370 mu of pineapple from 410 kg per mu in 1980 By 1986, 1400 kg of mu per mu was produced, of which 1522 mu of high-yielding cultivation experiments were averagely mu yielding 3522 kilograms and 5200 kilograms of mu.

江苏锡城“白领”刘女士到了35岁才怀孕,日前在做产前检查时让她大惊失色:肚里胎儿先天性脑积水,其脑子比正常胎儿大两倍,不仅生产时非常困难,而且产后若不能及时手术,很有可能夭折。   据市妇幼保健院透露:像刘女士这样的情况绝非少数,去年该院出生的4600多名新生儿中,围产儿死亡率近10%。其中,像患脑积水、消化道闭锁、先天性肢体缺损等新生儿先天性缺陷,占死亡原因的第一位。而且,许多先天性缺陷儿、畸形
