磷酸二氢钾为工业原料之一,近几年来被作为根外追肥或复合肥料的成分之一,在农业上试用,初见成效。矮壮素又名“三西”,是一种植物激素,在我市曾多次试验,但仍未应用于大面积生产。根据当前农业大上、快上的形势,为使这两种农用化学品尽快地在发展农业生产上起到应有作用,我们于1974、1975两年在农村基点与贫下中农一起,将这两种样品试用于几种大田作物上,取得了较好的效果,尤其是在甘薯和花生上积累了一些资料。试验证明,这两种化学品的合理施用,不仅能使作物生长健壮,增加抗病能力,而且有增产效果,为今后大力开展综合防治提供一项有效措施。
Potassium dihydrogen phosphate is one of the industrial raw materials. In recent years, it has been used as one of the components of top-dressing or compound fertilizers in the field and has achieved initial success in agriculture. Chlormequat also known as “three West” is a plant hormone, has repeatedly tested in our city, but has not yet been applied to large-scale production. In light of the current situation in agriculture and economy, in order to make both kinds of agricultural chemicals play their due role in the development of agricultural production as soon as possible, in the two rural areas of China in 1974 and 1975 together with the poor and poor peasants, Species of samples used in several field crops, and achieved good results, especially in sweet potatoes and peanuts have accumulated some information. Experiments show that the rational application of these two chemicals can not only make crop growth robust and increase disease resistance but also increase yield and provide an effective measure for vigorously carrying out integrated prevention and control.
