在油菜上进行了追施硫衣尿素和尿素的大田对比试验和示范 ,研究结果表明 :施硫衣尿素具有硫氮相互促进的增产作用 ;硫衣对尿素颗粒有明显的控释作用 ,在试验条件下 ,控释时间达 8d以上。硫衣尿素是油菜生长中后期追肥的理想肥料
The rapeseed was carried out in the field of sulfur dioxide urea and urea contrast test and demonstration, the results showed that: the sulfur sulfur urea nitrogen and sulfur each other to promote the yield; sulfur clothing on the urea particles have a significant controlled release in the test Under the conditions, the controlled release time reaches more than 8d. Sulfur clothing urea is the ideal fertilizer for top dressing in late rapeseed
