温州蜜柑无公害丰产栽培技术研究

Study on the Techniques of Pollution-free Satsuma Mandarin Cultivation

橘果品质的好坏和单位面积的产量,不仅影响其市场的占有率,同时还直接影响着产品的单价和果农的经济收入．兢如何提高橘果品质和单位面积产量,从水肥管理、土壤改良、修剪抹梢、保花促果、防治病虫等多方面进行了3年的技术改造和试验研究,结果表明:橘果产量由原来的15 173．25 kg/hm^2增加到试验研究后的65 897．25 kg/hm^2,后者是前者的4．34倍,最高的达103 455 kg/hm^2,是试验研究前平均产量的6．82倍;纯收入由试验研究前的7 095元/hm^2提高到试验研究后的72 790．35元/hm^2,后者是前者的10．26倍．

fruit quality and output per unit area influence not only the market-share, but also the price and fruit farm＇s income directly. In order to increase fruit quality and output per unit area, techniques innovation and researches have been done for 3 years, from many aspects, such as water and manure management, soil improvement, tree-pruning and sprout-picking, flower-retaining and fruit-increasing, and anti-lnsects and dlseases-preventing. The results show that the average output has increased 4. 34 times, namely from 15 173. 25 kg/hm^2 to 65 897. 25 kg/hm^2, and the highest output has reached 103 455 kg/hm^2, which is 6.82 times of the average output before improving; pure income after improving has increase 10.26 times, namely from 7 095 Yuan/hm^2 before improving to 72 790. 35 Yuan/hm^2.
