1、麦种浸泡在0.25的氯化钙或0.025的氯化钾水溶液中24小时后凉干播种,可增产20.2％,在小麦的灌水中加入十万分之五的钙,也可使小麦增产。 2、澳大利亚科学家发现,一种红真菌能使小麦等作物增产四成,主要是该菌的一种分泌物在起作用。 3、在盐碱土壤里,施用一定量的石灰粉,可使小麦大幅度增产。但只能水田在播秧前、旱田在作物定植后 1, Wheat seeds soaked in 0.25 of calcium chloride or 0.025 of potassium chloride solution 24 hours after dry sowing, yield 20.2% increase in wheat irrigation by adding five hundred thousandths of a million, can also increase the yield of wheat . 2, Australian scientists found that a red fungus can yield crops such as wheat 40%, mainly a secretion of the bacteria at work. 3, in saline soil, the application of a certain amount of lime powder, wheat yield can be substantially increased. However, paddy fields can only be sowed before they are planted
