The phenomenon of dead seedlings often occurs after the greenhouse vegetable seedlings are transplanted. The reasons for the analysis are roughly as follows.
First, the soil temperature is too low: due to the low soil temperature after transplanting, seedlings do not adapt to the new environment, not rooted in growth, unable to slow seedlings in time, resulting in dead seedlings.
Second, too much water loss: When transplanting too many seedlings, not a short time, so that the seedlings lose too much water and wilt, although pouring enough water, it is difficult to recover.
Third, root damage: Some seedlings before transplanting, less roots, poor development, it is difficult to slow seedlings after transplanting; Some seedlings, although growing well, but the seedlings, transplanting process due to technical inexperience, When the seedlings are squeezed by hand, the force is too great and the kneading is too tight, which damages the young stems, destroys the transporting tissues, and causes death after transplanting without absorbing water.
Fourth, the seedling age is too large: Transplanting too late, seedling age is too large, easy to root when lifting, the survival rate after transplantation is low.
V. Sunburn: Transplanting is carried out on a sunny day. After transplanting, there is no time to shade, and the seedlings that have just been transplanted in direct sunlight will cause burns and dead seedlings.
Sixth, the fertilizer kills the seedling: In the transplanting field applies the unripe farmyard manure, or has added the quantified fertilizer, or uses the excessive home of manure to cause the burning root to die.
