稀土微肥,商品名称叫“农乐”益植素。近年来,已在农业生产上广泛应用,均取得较好的增产效果。我市从1985年开始在西瓜上进行试验、示范、推广,到1988年止,全市西瓜施用稀土微肥面积已达1.5万余亩。实践证明,施用稀土的西瓜,不但增产显著,而且能增加西瓜甜度,改善西瓜品质。四年来的对比试验结果表明,施用稀土的西瓜,比对照增产16.4—22.8％,可溶性固形物提高0.73—1.05％,每亩净收入增加50元以上。一,增产增甜的原因。西瓜喷施稀土微肥后,能明显提高植株的叶绿素含量,干物质积累多,有利于植物对钾素的吸收,使养分集中向果实运转,
Rare earth fertilizer, product name is “agricultural music” beneficial plant. In recent years, it has been widely used in agricultural production and achieved better yield-increasing effect. The city started experimenting with watermelon from 1985, demonstrating and popularizing that until 1988, the area of watermelon applying rare earth fertilizer has reached 15,000 mu. Practice has proved that the application of rare earth watermelon, not only increase yield significantly, but also increase the sweetness of watermelon, improve watermelon quality. Four years of comparative test results show that the application of rare earth watermelon yield 16.4-22.8% more than the control, soluble solids increased 0.73-1.05%, net income per acre increased more than 50 yuan. First, the increase of sweet reasons. Watermelon spraying rare earth fertilizer, can significantly improve the chlorophyll content of plants, dry matter accumulation, is conducive to plant potassium absorption, the nutrients concentrated to the fruit operation,
