龙宝区果品结构调整调以脐橙为主的良种高换工作,近年来高潮叠起,每年高换20万株以上.然而高换后一般要影响果园2—3年产量,为解决这一矛盾,我们从九四年起着手引进无籽西瓜试验示范推广,在高换树下以及新建果园种植无籽西瓜取得显著成效.虽然高换后柑桔产量减少,但由于无籽西瓜丰收,经济效益反而对未高换果园明显提高.无籽西瓜从育苗至采收仅100～120天,亩平产量2500—3000kg,亩纯收入达3000余元,比未改换果园的柑桔纯收入增长1.72倍.为我区柑桔高换良种后如何解决短期内经济效益下降的问题提供典型经验.种植无籽西瓜的优势首先是见效快,当年种植,当年见效.二是经济效益高.无籽西瓜具有多倍体和杂交一代的双重优势,种植得法,平均亩产3000公斤以上,亩产值在3000多元.三是市场潜力大,无籽西瓜属高挡西瓜,味甜无籽,食用既卫生又方便,深受消费者喜爱,市场供不应求.四是通过嫁接技术的应用,无籽西瓜完全能够连年种植,形成无籽西瓜产业化生产,促进农村经济的发展.
Longbao District, adjust the structure of fruits transferred to the orange-based seed for the work of high turnover, in recent years climax stacked, high for more than 200,000 per year, however, after the general change to affect the orchard 2-3 annual output, in order to resolve this contradiction , We started to introduce the demonstration and promotion of seedless watermelon experiment from 1994, and achieved notable successes in growing seedless watermelons under high-change trees and new orchards. Although the yield of citrus decreased after the high-turnover, due to the good harvest of seedless watermelon, the economic benefits But not significantly higher for the orchard improved seedless watermelon from seedling to harvest only 100 to 120 days, mu flat output 2500-3000kg, net income of 3000 yuan more than the unchanged orchard citrus net income increased 1.72 times For my area of citrus high seed for improved seed how to solve the problem of short-term decline in economic benefits to provide the typical experience of the advantages of planting seedless watermelon is the first quick, then planting, when the effect of the second is the economic benefits of seedless watermelon has Polyploid and hybrid generation of double superiority, planting law, the average yield of 3000 kg per mu, more than 3000 yuan in output value. Third, the market potential is high, seedless watermelon is a high block watermelon, sweet seeds, food is both hygienic and convenient , By consumers Love, the market demand. Fourth, through the application of grafting techniques, seedless watermelon fully able to grow year after year, the formation of seedless watermelon industrial production, promote rural economic development.
