小分子诱导制剂在露地甘蓝上的应用效果研究

Effect of Small Molecule Inducer on Outdoor Cabbage

为研究小分子诱导制剂在露地甘蓝上的应用效果,探明最佳施用方法,开展了不同施肥方法试验。结果表明,小分子诱导制剂具有促进植株生长、增强抗逆性、提高产量的作用。定植时用小分子诱导制剂300倍液蘸根+定植后喷施小分子诱导制剂300倍液3次(间隔10～15 d喷施1次),肥效持续时间长,增产幅度达到21.21%。

In order to study the effect of small molecule inducer on outdoor cabbage and find out the best application method,a fe^ilization experiment with different methods was carried out.The results indicated that the small molecule inducer could promote plant growth,enhance stress resistance and increase yield.300 times liquid of small molecule inducer was used for dipping the root during planting and spraying 3 times after planting(once every 10-15 days),fertilizer effect lasted long and the yield increased to 21.21%.
