香蕉在我省水果生产中占有重要位置,称南方四大水果之一。近年来由于冻害严重,产量大幅度下降,直接影响香蕉生产。我场1975年冻害前香蕉平均亩产2350斤,1976年冻害后亩产只有181斤,比1975年减产93％,1977年平均亩产767斤,比1975年减产68％。1978年我们加强管理,这年全场平均亩产上升到2365斤,比冻害前1975年亩产量还要多。因此,解决香蕉防寒和冻害后如何增产,是香蕉生产中一个突出的重要环节。一、香蕉的冻害香蕉原产于亚洲热带地区,生长要求比较高的温湿度,在温度26—30℃,雨量充沛,阳光充足时,它的生长速度最快,每月新抽叶达
Banana fruit production in our province occupy an important position, said one of the four southern fruits. In recent years, due to severe frost damage, the output dropped significantly, directly affecting banana production. Before the frost damage in 1975, the average yield of bananas in the field was 2,350 kg. In 1976, the per-mu yield was only 181 kg after frost damage, down 93% from 1975. The average yield per mu in 1977 was 767 kg, down 68% from 1975. In 1978, we stepped up management. The average mu production in this year rose to 2365 kg, more than in 1975 before the frost damage. Therefore, to solve the banana cold and frost damage how to increase production is a prominent banana production an important part. First, banana frost damage Banana originated in the tropical region of Asia, the growth of relatively high temperature and humidity, at a temperature of 26-30 ℃, abundant rainfall, sunny when it grows fastest, the new monthly leaf up Tatsu
