柑桔错峰成熟技术及果实错峰上市效益初探

Primary exploring technology on stagger mature of Citrus fruit and economic benefits of stagger market

8～9月向贡柑植株喷施两次0.2%KH2PO4+0.1%H3BO3,可促进向阳果实于11月初成熟上市;采收后立即喷施DA-6,可显著增加留树果实的可溶性固形物含量,提高冷期的好果率。GA3、DA-6和NPK复合肥联合处理可极显著减轻迟采收沙糖桔果实的冷害,使其在1月底至2月初上市。以上技术措施由于可使果实提早和推迟成熟上市,因此可减轻中段的销售压力,从而使剩下的果品在中段避开峰期、按市场需要上市,获得较好的经济效益。

Citrus cv. gonggan trees were sprayed twice with 0.2%KH2PO4＋0.1%H3BO3 on Augest to September, the mature time of the fruits facing sunlight could be advanced to the early days of November, when the fruits could be harvested and early come onto markets. And then DA-6 were immediately sprayed on the left fruits of trees, which could significantly increase the soluble solids content, and increased the rate of intact fruit under cold period. The combining treatment of GA3, DA-6 and NPK fertilizer significantly reduced cold damage to fruits of Citrus cv. Shatangju at late harvest, and market in the late January to early February. Because of the fruits of early and delayed markets could get higher economic efficiency, thus the sale pressure was reduced for the left fruits during middle period, which could be sold by better economic benefits according to the market need, avoiding peak period.
