VDAL是由工程菌株发酵特殊生产工艺制备的蛋白干粉，具有促控植物发芽与出苗、诱导植物抗性、促进植物生长发育、提高作物产量及改善品质等功效。本试验在江苏泰州姜堰区实施，通过对小麦不同生育时期施用不同浓度VDAL进行大田试验，结果表明，VDAL提高小麦产量效果显著，增强苗体素质，提高纹枯病抗性，白粉病防效比用药好，对赤霉病没有防效，拔节期喷施效果好于拌种，VDAL+用药增产和防病效果更好。
VDAL is a dry protein powder prepared by a special fermentation process of engineered strains. It has the effects of promoting and controlling plant germination and emergence, inducing plant resistance, promoting plant growth and development, increasing crop yield and improving quality. This experiment was carried out in Jiangyan District, Taizhou, Jiangsu. Field experiments were conducted by applying different concentrations of VDAL to different growth periods of wheat. The results showed that VDAL has a significant effect on improving wheat yield, enhancing seedling quality, improving resistance to sheath blight, and preventing powdery mildew. It is better than medication, and it has no effect in preventing head blight. The effect of spraying at jointing stage is better than that of seed dressing. VDAL+ medication increases production and has better disease prevention effect.
