土壤速效磷含量的丰歉是土壤肥力的一个重要因素。在土壤缺磷或含磷量低的情况下,芝麻生长代谢中碳水化合物、蛋白质和脂肪的转化都会受到阻碍,致使植株矮小、开花结实少,种子产量和含油量都明显降低。根据我们在缺磷土壤上进行磷肥施用技术研究的结果,采用下述三种方法增施磷肥,具有普遍促进芝麻生育和提高单产的作用。
Soil apowerful phosphorus content apricot soil fertility is an important factor. In the case of phosphorus deficiency or phosphorus deficiency in the soil, the conversion of carbohydrate, protein and fat in sesame growth and metabolism will be hindered, resulting in short plants, less flowering and less seed yield and oil content. According to the results of our research on the application of phosphate fertilizer in phosphate-deficient soils, the following three methods were used to increase the application of phosphate fertilizer, which has the general effect of promoting sesame growth and improving yield.
