自制石骨子三合肥是用1,000斤石骨子或肥泥、塘泥加碳铵或氨水30斤、过磷酸钙30斤,混合均匀,密封堆沤半月到一月即成。施用石骨子三合肥的好处:①肥效长,增产效果好。研究表明,石骨子三合肥可防止氯的挥发,延长氮的肥效。把石骨子三合肥与等氨量碳铵施入土中,第1天略高于对照的挥发量,其余的5、10、20、30和40天碳铵的挥发量显著低于对照。施入土中40天,石骨子三合肥氨损失6.7％,单施碳铵,氨损失36.54％。因 Self-made stone bone Three Hefei is the use of 1,000 pounds of stone or fat mud, pond plus ammonium or ammonia 30 kg, 30 kg of superphosphate, mixed evenly, sealed heap half moon to January Serve. The benefits of using stone bones three Hefei: ① fertilizer efficiency, good yield. Research shows that stone bone three Hefei can prevent the volatilization of chlorine, nitrogen fertilizer to extend the efficiency. Shihugu Sanhe fertilizer and ammonium bicarbonate were applied to the soil, the first day slightly higher than the control of the amount of volatilization, and the remaining 5,10,20,30 and 40 days of ammonium bicarbonate volatilization was significantly lower than the control. 40 days into the soil, stone bone triagonal ammonia loss of 6.7%, ammonium bicarbonate alone, ammonia loss of 36.54%. because
