几年来,自治区化肥供应量不断增加,对农业增产起了一定的作用。据各地生产和试验证明,一般每斤硝酸铵能增产籽棉1—2.5斤,玉米4—9斤,冬麦2—9斤,水稻3—7斤,多穗高梁3—14斤,甜菜25—30斤;每斤过磷酸钙能增产籽棉0.3—1.5斤,玉米0.8—3.5斤,冬麦0.5—1.0斤,水稻2斤,甜菜8—13斤,大豆1.6斤,苜蓿干草9—12斤,草木樨干草28—52斤。过磷酸钙施于豆类作物和豆科牧草,可以“以磷换氮”,发挥更大的增产作用。
In the past few years, the supply of fertilizer in the autonomous region has been increasing, which has played a certain role in increasing agricultural output. According to local production and test proved that the general per kilogram of ammonium nitrate can increase seed cotton 1-2.5 kg, 4-9 kg of corn, 2-9 kg of winter wheat, 3-7 kg of rice, more spike sorghum 3-14 kg, beet 25- 30 kg; per kilogram of superphosphate can increase 0.3-1.5 kg of seed cotton, corn 0.8-3.5 kg, winter wheat 0.5-1.0 kg, 2 kg of rice, sugar beet 8-13 pounds, 1.6 kg of soybeans, alfalfa hay 9-12 pounds, Haysticks Hay 28-52 kg. Application of superphosphate in leguminous crops and leguminous forage grass, “phosphorus to nitrogen” to play a greater role in increasing production.
