The invention discloses an accelerating germination and efficient cultivation method for summer squashes. The method comprises the following steps that of (1) seedbed preparation, (2) lukewarm water seed soaking, (3) accelerating germination, (4) root tip growing point passivation, (5) sowing, (6) seedling stage management, (7) soil preparation, fertilization application and field planting, (8) disease and pest prevention and (9) topdressing and harvesting. According to the accelerating germination and efficient cultivation method for summer squashes, a hole tray is used for seedling cultivation in a simple greenhouse in the seedling cultivation stage, the nutrients, temperature, water and light environment conditions needed by growing of seedlings of the summer squashes can be better provided, bad effect on the seedling cultivation process of severe variation of the environment conditions is avoided, the problems that the ages of the seedlings in the same hole tray are not consistent, the sizes of the seedlings are not consistent, and the index of strong seedlings is low are solved, and the 100% seedling emergence rate of the seedlings in the hole tray is guaranteed. Meanwhile, root tip growing points are passivated, growing of main roots can be effectively restrained, growing of side roots is promoted, the length of a plumular axis is reduced, so that the main roots of sowed summer squashes are short, fibrous roots are many, surviving is quick after transplanting and field planting, the growth vigour is high, and the disease resistance is high.
