稀土在苹果、葡萄、梨、枣、柑桔等十几种果树上已大面积应用,并取得了突破性进展。果树施用稀土投资少,见效快、效益高,是果品生产中一项短、平、快的增产新技术。稀土可有效地提高果树叶片的叶绿素含量,使叶片浓绿,增大,叶质改善,光合作用增强,有利于光合产物的生成和积累,促进了果树的营养生长,提高座果率,增加产量,改瞢品质,增强耐贮性。为了更好的发挥稀土的作用,可结合喷施,采取配套的农业技术措施,达到增产的目的。一、稀土和矿质元素肥料配施在苹果树上用500ppm稀土溶液和500倍的复合液肥混合,于盛花期与幼果膨大期各喷一次。可使叶绿素含量增加22.31％,百花序座果数增加85。57％,产量增加20％以上。该肥用量少,见效快,使
Rare earth in apple, grape, pear, jujube, citrus and more than a dozen kinds of fruit trees have been large-scale application, and made a breakthrough. Fruit trees use less rare earth investment, quick, high efficiency, is a short, flat, fast stimulation of fruit production technology. Rare earth can effectively improve the chlorophyll content of fruit leaves, make the leaves dark green, increase, leaf quality improved, photosynthesis enhanced, is conducive to the formation and accumulation of photosynthetic products, promote fruit tree vegetative growth, increase fruit set rate and increase yield , Change 瞢 quality, enhance storability. In order to better play the role of rare earth, can be combined with spraying, take supporting agricultural technology measures to achieve the purpose of increasing production. First, the rare earth and mineral elements Fertilizer with apple 500ppm rare earth solution and 500 times the compound liquid fertilizer mixed, full bloom and young fruit inflatable spray once. The content of chlorophyll increased by 22.31%, the number of flowers increased by 85.57% and the yield increased by more than 20%. The fertilizer less, quick, so
