1.在所研究的华南某些砖红壤和红壤中,多数土壤的硼钼供应都不充足。2.在花岗岩、片麻岩、浅海沉积物和第四纪红色粘土等母质发育的砖红壤性红壤及红壤上,盆栽花生和黄豆,施用硼肥对增产果荚、种籽都有明显作用,而且降低了果荚的空瘪率。对豆科作物施用钼肥,能使茎叶增重并提高茎叶中的含氮量。因此,在这些土壤上种植豆科绿肥作物,施用钼肥是值得重视的。3.在凝灰岩和玄武岩发育的砖红壤上,种植豆科作物,施用钼肥对提高种籽产量和茎叶含氮量都有明显作用。在凝灰岩发育的砖红壤上,单施硼肥,无论对种籽和茎叶都无明显作用,只有与钼肥配合施用时,才表现出一定的效应。4.在石灰岩发育的棕色石灰土上种植豆科作物,无论施用硼肥或钼肥,都无明显的作用。在第三纪红砂岩发育的红壤上,种植豆科作物,施用硼肥有一定的作用,但未达到统计上的显著水平。
1. In some of the brick red and red soils studied in southern China, the supply of boron and molybdenum in most soils is not sufficient. 2. Peanut and soybean plants were potted in the red loam and red soils derived from the parent materials of granite, gneiss, shallow sea sediments and Quaternary red clay, and the application of boron fertilizer had a significant effect on increasing the yield of pods and seeds, But also reduce the empty pod rate. Applying molybdenum fertilizer to legume crops can increase stem weight and increase nitrogen content in stems and leaves. Therefore, the cultivation of leguminous green manure crops in these soils, the application of molybdenum fertilizer is worth attention. 3. In legumes with tuff and basalt development, leguminous crops were planted and the use of molybdenum fertilizer had a significant effect on improving seed yield and nitrogen content in stems and leaves. On the brick soil with tuff development, applying boron fertilizer alone had no significant effect on the seed and stems and leaves, and only showed some effect when mixed with molybdenum fertilizer. 4. There is no significant effect on the cultivation of leguminous crops on brown limestone with limestone development, irrespective of the application of boron or molybdenum fertilizer. On the red soils developed in the red sandstone of the Tertiary, the leguminous crops were planted and the application of boron fertilizer had a certain effect, but did not reach the statistically significant level.
