氨水是一种新型的液体氮素化肥,一般含氮量17%左右。过去有些群众认为肥效不高,施用方法不易掌握,因而很少使用。但据桓台县索镇区侯庄大队1964年小麦返青期试验,追施氨水比不追的增产15-22.2%,而且不论株高、穗长、每穗小穗数、每亩穗数均高于不追氨水的。特别是每亩穗数差异更为显著,两者相差1.45万-2.07万穗,这是增产最可靠的保证。
Ammonia is a new type of liquid nitrogen fertilizer, generally about 17% nitrogen. In the past, some people think that the fertilizer effect is not high, and the application method is not easy to grasp, so it is rarely used. However, according to the Huantai County town of Hou Zhuang Brigade 1964 wheat turning green test, chasing ammonia than not chasing the yield 15-22.2%, and regardless of plant height, spike length, number of spikelets per panicle, per acre spike number Than not recovering ammonia. In particular, the difference between the number of spikes per acre more significant, the difference between the two 14500 -2.07 million spike, which is the most reliable guarantee of yield.
