2,3-二氯异丁酸钠的合成及其在水稻增产上的应用

Synthesis of 2,3-Dichloroisobutyrate Sodium and Its Application on Rice

2，3－二氯异丁酸钠是一种较新的植物生长调节剂．本文按沈凤嘉等人的改进方法合成了该物质，所得产品的红外光谱图与标准图谱基本吻合．将2，3－二氯异丁酸钠配制成不同浓度的水溶液施用于水稻，发现该物质对水稻的产量有影响：既有增产作用，也有减产作用，与施用浓度有关．

2, 3-dichloroisobutyrate sodium is a new plant growth regulato. The substance is synthsized with the method improved by Shen Fenaiua et al, The IR spectrum of the synthetic substance coincides with the standard one well. While used onto rice in different concentration, 2, 3-dichioroisobutyrate sodium is discovered to affect the yield of rice - increase or decrease, according to the concention.
