近两年,我县引进重庆市江津县朱杨宇航日用化工厂生产的宇航牌多元素高级复合肥,在花生上进行叶面喷施试验示范,获得显著增产。在花生苗期和盛花期各喷施1次,植株明显增高,茎枝粗壮,叶色变浓,病害减轻,荚果数增加,出仁率提高。据对比试验,比喷清水的单株荚果数多0.87个,壮果数多2.2个,饱果率提高3.8%,百果重增加14.6克,出仁率提高0.7%,百仁重增加9.7克,亩增产73.5公斤,增产32.3%。使用方法:在花生苗期和盛花期,每亩每次用多元素高级复合肥8～10包(每包20克)对水60公斤用喷雾器喷雾,共喷施2次,力求叶子正反两面均匀喷到,施用时间以晴天上午10时以前或下午4时以后,喷后6小时内如遇雨,应及时补施。
In the recent two years, our county introduced Aerospace brand multi-element advanced compound fertilizer produced by Zhu Yang Aerospace Routine Chemical Plant in Jiangjin County of Chongqing Municipality to conduct demonstration experiments on peanut spraying and obtain significant increase in output. Spraying at the peanut seedling stage and the full flowering stage, the plants were significantly increased, stalks thick, leaf color thickening, disease alleviation, pods increased, kernel rate increased. According to the comparative test, the number of pods per plant was 0.87 more than that of spraying water, the number of strong fruits was 2.2, the full fruit rate increased by 3.8%, the fruit weight increased by 14.6 g, the kernel rate increased by 0.7% and the weight per head increased by 9.7 g , Yield 73.5 kilograms of mu, increase yield 32.3%. How to use: In peanut seedling stage and flowering stage, use multi-element advanced compound fertilizer per mu for 8-10 packets (20g each pack) and spray 60kg of water with a sprayer for a total of 2 times to strive for the positive and negative sides of leaves Evenly sprayed, the application time to sunny before 10 o’clock or after 4 o’clock in the afternoon, within 6 hours after the spray in case of rain, should be promptly replenishment.
