“农乐益植素”是含有镧、铈、镨、钕四种微量元素的硝酸稀土,这些元素在作物体内能加强酶的活性,促进新陈代谢,提高光合效率,促使植株对氮、磷、钾的吸收和运输。去年,我们在芙芸乡四个村的3000亩棉田上进行喷施“农乐益植素”的试验示范,在棉花盛蕾期每亩喷施30克,试验结果表明:喷施“农乐益植素”能使棉株叶色加 “Nong Lok Yi Su” is a rare earth nitrate containing trace elements of lanthanum, cerium, praseodymium and neodymium. These elements can enhance enzyme activity, promote metabolism, enhance photosynthetic efficiency and promote nitrogen, phosphorus and potassium Absorption and transport. Last year, we experimented with 3000 yuan of cotton fields in four villages in Fuyun Township and sprayed 30 grams per mu in cotton buds. The results showed that spraying “Nongle Agrostat ”can make cotton plant color plus
