在生产实践中,有些社员不了解化肥的性质,滥用化肥。错误地认为,只要是有机肥料中掺进任何一种化肥,或者几种肥料混用,就能提高肥效,结果事与愿违。如碳铵是当前农业生产上常用的速效氮肥,它不能与尿素、氨水、人畜粪尿、钙镁磷肥、磷矿粉、骨粉、草木灰、石灰、圈杂肥混施。这是因为碳铵是一种不稳定的化合物,又是碱性肥料、而尿素、氨水、人畜粪尿、钙镁磷肥、磷矿粉、骨粉、草木灰、石灰、因杂肥亦是碱性肥料,如果混施,只能提高碱性,促进氨态氮加快挥发,降低肥效。因此,必须严格掌握肥料的性质,科学地混施肥料,才能充分地 In production practice, some members do not understand the nature of fertilizers and abuse chemical fertilizers. Wrongly believe that as long as the organic fertilizer mixed with any kind of fertilizer, or mixed with several kinds of fertilizers, can improve fertilizer efficiency, the result is contrary to expectations. Such as ammonium bicarbonate is currently used in agricultural production of quick-acting nitrogen fertilizer, it can not with urea, ammonia, manure excrement, calcium magnesium phosphate, phosphate rock meal, bone meal, ash, lime, This is because ammonium bicarbonate is an unstable compound, but also alkaline fertilizers, and urea, ammonia, human and animal excreta, calcium magnesium phosphate, phosphate rock, bone meal, ash, lime, also due to miscellaneous fertilizer is alkaline fertilizer If mixed, can only improve the alkaline, ammonia nitrogen to promote faster volatilization and reduce fertilizer. Therefore, we must strictly grasp the nature of fertilizer, fertilizers scientifically mixed in order to fully
