橡胶树生长和产胶除需要大量营养元素外,还需要各种微量元素。螯合稀土钼微肥具有营养和刺激作用。为了探索稀土微肥在云南垦区橡胶生产上的施用技术及其效果,我们于1986—1987年进行了试验研究,同时在生产上推广应用。现将试验结果初报如下:一、试验材料与方法试验布置于本所三、四实验队,土壤为老冲积物发育的砖红壤性土,自然肥力较好的缓坡谷地上。1986年试验采用割面 Rubber tree growth and production of plastic in addition to a large number of nutrients, but also need a variety of trace elements. Chelated rare earth molybdenum fertilizer with nutrition and stimulation. In order to explore the application of rare earth fertilizer in Yunnan reclamation rubber production technology and its effect, we conducted in 1986-1987 years of experimental research, while promoting the production. First, the test results are reported as follows: First, the test materials and methods The experiment was arranged in the three or four experimental team, the soil is the old red alluvial brick soil, natural fertility is better on the gentle slope valley. 1986 test using cutting surface
