磷肥是一种增产显著、肥效期长的肥料。施用磷肥是提高地温,促进幼苗早生快发,加速根系生长,提高分蘖率,增加籽实重量、提高单产的有效措施。为了使磷肥应用于生产,在过磷酸钙还不能满足需要的情况下,我们根据腐植酸能固氮活磷的道理,搞了磷矿粉拌酸菜水发酵后的肥效试验。一、试验方法我们在示范场二队选择地力比较均匀、未施农肥的地块做试验小区。试验共分四个处理:
Phosphate fertilizer is a significant yield, fertilizer long period of fertilizer. Application of phosphate fertilizer is to improve ground temperature, promote seedling early hair faster, accelerate root growth, increase the tillering rate, increase seed weight, improve the yield of effective measures. In order to make the phosphate fertilizer used in the production, the superphosphate can not meet the needs of the case, we can nitrogen fixation based on the principle of humic acid phosphorus, put the phosphate rock meal with pickled water fermentation efficiency test. First, the test method We selected in the demonstration field two teams more uniform soil fertility, no plots of plots to do test. Test is divided into four treatment:
