赤霉素和肥料并用后,对春菠菜都引起了一定的反应,但反应的大小有差异。噴布了赤霉素的一般施肥小区,第三天叶色开始出現黄綠色,延續时間較长,株势直立向上,株高迅速增加,花蕾出現較早;而在高肥和赤霉素结合区,則看到上述黄化現象恢复时間較短,噴后第五天即恢复濃綠,株势增强,叶面积增大。以百万分之二十赤霉素在春菠菜生长盛期(6—7叶)噴布一次,对春菠菜已見增产效果;而当结合 Gibberellin and fertilizers, after the spring spinach have caused a certain response, but the size of the response differences. Sprayed GA3 general fertilization plot, the third leaf color began to appear yellow-green, longer duration, plant potential upright, plant height increased rapidly, buds appear earlier; and in the high-fat and gibberellin Combined with the area, we can see the above phenomenon of yellowing recovery time is short, the fifth day after spraying to restore dark green, plant potential increased leaf area increased. Spraying once in 20% of gibberellic acid in the spring spinach growing season (6-7 leaves), the yield has been increased on spring spinach; when combined
