1971年我场在磷肥供应不足的情况下,把从区化工厂买来的300多吨骨粉,经硫酸处理后用于大田,收到了良好的增产效果.现将用硫酸处理的骨粉与其它几个磷肥品种的肥效比较试验结果简报于后,供参考.一、在小麦上的肥效试验我场种子连在13号地,以“劲麦1号”为供试作物,用硫酸处理的骨粉,同未经硫酸处理的骨粉及过磷酸钙作肥效比较试验.小麦前茬为水稻.播前基施马圈粪1万斤,每亩以10斤尿素作种肥,在此基础上,每一处理(除对照外)分别亩施硫酸处理的骨粉、未处理的骨粉、过磷酸钙40斤作种肥施入.苗期(4月12
In 1971 my field in the case of inadequate supply of phosphate fertilizer, from the District Chemical Plant bought more than 300 tons of bone meal, after the sulfuric acid used in the field, received a good yield. Now sulfuric acid treatment of bone meal with several other Fertilizer efficiency of a phosphate fertilizer varieties The results of the comparison report after the trial for reference.First, the fertilizer effect test on wheat I field even in the thirteenth seed, with “Jinmai 1” for the test crop, with sulfuric acid treatment Bone meal, with the non-sulfate-treated bone meal and superphosphate fertilizer for comparison.Pre-crop of wheat is rice.Before the preculture of stoma precinct 1 kg, per acre with 10 kg of urea as seed fertilizer, on this basis, Each treatment (except control), respectively, mulberry sulfuric acid treatment of bone meal, untreated bone meal, 40 kg of superphosphate as seed fertilizer into the seedling stage (April 12
