葡萄为喜光果树,而棚室内的光照强度常常不足室外的70%,这样的光照强度对葡萄的生长和结果都有显著的不良影响,常常造成严重的落花落果,果实着色不良,含糖量低,花芽分化不良等现象,大大降低了温室葡萄的产量和质量,使设施栽培葡萄难以达到优质、高产、高效的目的。因此,增强温 The grapes are like a light fruit tree, and the light intensity inside the shed is often less than 70% of the outdoors, which has a significant adverse effect on the growth and outcome of the grapes, often resulting in severe drop shading, poor fruit coloration, low sugar content , Poorly differentiated flower buds and other phenomena, greatly reducing the yield and quality of the greenhouse grape, grape cultivation facilities to achieve high quality, high yield, high efficiency purposes. Therefore, to enhance the temperature
