照最近关年来全世界各地闹着粮荒的情形看来,粮食增产实在是国家最重要的一种政策。当然,要粮食增产,像吾国这样仅用靠天吃饭的祖传老方法是决不能做到的,必须要配上各种最科学的方法。试看农业发达的外国情形怎样呢?他们应用科学的设备,还能孜孜不倦的努力于增产的发明。其最为重要的,当推病害虫及杂草的消除方法,但到最近又有所谓植物荷尔蒙制剂的发明,因而粮食增产运动得以更加推进。 In the light of the recent food shortage in all parts of the world in the past year, it is indeed the most important policy for the country to increase grain output. Of course, to increase grain output, the old method of amending the ancestry, such as ours, that can only eat by the sky can never be done. The most scientific method must be accompanied by it. Trying to see what happens to the developed agriculture in foreign countries, they apply scientific equipment and can make unremitting efforts in increasing inventions. The most important thing is that when pests and weeds are eliminated, the so-called phytohormones have recently been invented and the grain production campaign has been further promoted.
