我省核桃主要品种于白露前后成熟。这时采收正值秋收农忙时期,常因劳力不足,核桃不能及时采收,或采后堆放过久,种皮变黑或发芽霉烂,严重地影响核桃的美观和品质。为了解决核桃采收与秋收争劳力的矛盾,我们于一九七五、七六年在漾濞马厂古迷么生产队使用乙烯利对即将成熟的核核进行催熟,试验结果,乙烯利对核桃有明显的催熟作用。现就使用方法作介绍。一、树上催熟法:当树上出现少数裂果核桃后,用500倍浓度的乙烯利水溶液喷雾到果面潮润,三天后果皮由淡黄绿色逐渐转变为黄绿色,并有小裂缝出现,六至七天裂果可达95％以上,此时便可采收。用这种方法处理能使核桃成熟一致,便于采收,离壳容易,不需后熟处理,可缩短时间,节省劳力,种壳较白,增加表面美
The main varieties of walnut in our province before and after the mature white dew. Harvest time at this time is harvested during the busy autumn, often due to labor shortage, walnut can not be harvested in time, or too long after the piling, seed coat black or sprouting mildew, seriously affecting walnut beauty and quality. In order to solve the contradiction between the harvest of walnuts and the labor force for the autumn harvest, we used ethephon to mature ripe nuclei in 1975 and 1976 in our factory in Yangbi, Walnuts have obvious ripening effect. Now use the method for introduction. A tree ripening law: When the tree appears a few cracked walnuts, with 500 times the concentration of ethephon aqueous solution spray to the surface moist, three days after the peel from yellowish green gradually transformed into yellow-green, and there are small cracks, Six to seven days cracked fruit up to 95% or more, at this time can be harvested. With this method of processing can make the walnut mature and consistent, easy to harvest, the shell is easy, without post-maturing treatment, can shorten the time, save labor, the shell is white, increase the surface of the United States
