前言近年来,磷酸二氢钾和三十烷醇被广泛用来进行小麦根外喷施,增产效果十分明显。据申玉清大面积试验表明,小麦孕穗期每亩用3两磷酸二氢钾进行根外喷施可增产6—9％。王忠孝等用0.1ppm三十烷醇于小麦孕穗和开花期进行叶面喷施,增产5—8％。黑龙江海伦农场陈乃康用飞机亩喷三十烷醇1毫升加磷酸二氢钾150克可增产13.6％。本文旨在对磷酸二氢钾和三十烷醇二者混合喷施的效应作进一步探讨,为小麦高产栽培提供理论依据。材料与方法试验于1984年在五三农垦科研所进行。试验地为一级原种田,黄泥土,中壤,肥力
Preface In recent years, potassium dihydrogen phosphate and triacontanol are widely used to spray wheat root, the yield is very obvious. According to Shen Yu-ching large area experiments show that wheat booting per mu with 3 potassium dihydrogen phosphate for root spray can increase 6-9%. Wang Zhongxiao and other 0.1ppm triacontanol in wheat booting and flowering foliar spray, an increase of 5-8%. He Nirongnong Heilongjiang farm Chen Naikang plane spraying acacia alcohol 1 ml plus potassium dihydrogen phosphate 150 grams can increase 13.6%. The aim of this paper is to further investigate the effect of mixed spraying of potassium dihydrogen phosphate and triacontanol, which provides a theoretical basis for high-yielding wheat. Materials and Methods The experiment was carried out in 1984 at 53 State Farms Research Institute. Test for a primary farming, yellow soil, soil, fertility
