皖沿江棉区内质微网控失型复合肥试验研究

Research on the Experiment of Applying Inside Micronet Loss-Control Fertilizer on Cotton Field along the Yangtze River in Anhui Province

对内质微网控失型复合肥和普通复合肥进行多点对比试验,以提高棉田肥料的利用率。结果表明:内质微网控失型复合肥具有节本、增产、增效的作用,且棉株前期不旺长,后期不早衰。

In order to improve the utilization rate of fertilizer cotton, we compared the fertilizer efficiency on cot- ton between inside micronet loss-control fertilizer and common compound fertilizer. The results showed that the inside micronet loss-control fertilizer had a great effect in cost saving, increasing production and efficiency. With inside micronet loss-control fertilizer, the cotton plant would not grow strong in earlier stage and not be prema- ture senility latter.
