原宁夏地区的土壤,根据我所化学分析资料证明,除含氮不足外,并普遍的缺乏磷质,由于磷质能够促进种籽发芽幼苗生长,和子实饱满,提早成熟,增加作品产量,故配合氮肥给土壤中施入磷肥是提高单位面积产量保证丰收的重要关键,我所针对着这种肥源缺乏和利用废物,于1952年开始收集散弃荒野的兽骨。制成富含磷质的骨粉(根据本所分析的结 The original Ningxia soil, according to my chemical analysis of data that, in addition to nitrogen deficiency, and the general lack of phosphorus, because phosphorus can promote seedling seedling growth, and fruit full, early maturity, increase production output, so With the application of nitrogen fertilizer to soil phosphate fertilizer is to improve yield per unit area to ensure a good harvest, I aimed at the lack of such fertilizer and the use of waste, in 1952 began to collect the abandoned animal bones. Made of phosphorus-rich bone meal (according to the analysis of the knot
