液氨的含氮量高达82.35%,是一种高效液体氮肥.为了探讨液氨直接施肥在水稻生产上的应用价值,我们在化工部的支持下,对早、晚稻进行了三年的试验示范.1979年的示范面积达6,837亩,其中机器施肥面积占97.5%.试验在6个单位用大区对比法进行,以等氮量的碳酸氢铵或其他氮肥作对照.供试品种为各单位的当家品种,多数试验点的土壤为青紫泥.现将初步结果报道如下.
Liquid ammonia nitrogen content is as high as 82.35%, which is a kind of high efficient liquid nitrogen fertilizer.In order to explore the application value of direct liquid ammonia fertilization in rice production, with the support of Ministry of Chemical Industry, we carried out three years experimental demonstration .In 1979, the demonstration area was 6,837 mu, of which 97.5% of the area was fertilized by the machine.The test was carried out in six units by the method of large area comparison with the same amount of ammonium bicarbonate or other nitrogenous fertilizer as the control.The tested varieties were all units Of the original varieties, most of the test sites for the purple soil purple soil now report the following preliminary results.
