本试验通过六个不同类型的品种对在新疆条件下玉米产量形成的几个基本问题进行了探讨,得初步结果如下:(一)玉米为形成一定数量的生物产量,从土壤中吸取的氮磷量,品种间差异不大。(二)玉米植株中部叶(包括棒三叶)的功能和上部叶有显著不同。(三)玉米植株许多器官具有贮备营养物质的过程,茎基部第一至八节干重变化是双峰曲线。(四)玉米在大喇八口期前后正是穗位以上叶片扩大面积增加干重的重要时期。(五)对当地玉米为达到千斤产量各时期群体应达到的光合势、叶面积系数及地面透光率提出了初步看法。
In this experiment, several basic problems of maize yield formation under Xinjiang condition were discussed through six different types of cultivars. The preliminary results are as follows: (1) Corn is a certain amount of biological yield, nitrogen and phosphorus Amount, little difference between varieties. (B) corn plant central leaf (including the stick clover) function and the upper leaf significantly different. (C) many organs of corn plants have the process of storage of nutrients, stem base section 1 to 8 changes in dry weight is a bimodal curve. (D) before and after the big mouth in the big mouth eight is spike bit above the leaves to expand an important area to increase dry weight. (E) The preliminary opinions on the photosynthetic potential, leaf area coefficient and light transmittance of the ground that the local maize should reach for each stage of production are reached.
