There are many problems in raising seedlings at high temperature, and vegetable farmers should be cautious in selecting seedlings

During the seedling period of summer vegetables, high temperature, diseases and insect pests bring many difficulties to the seedling work, and it is easy to cause vegetable seedlings to be infected, such as stem base rot, virus disease, etc. If such seedlings are purchased, pathogenic bacteria and eggs will be brought to vegetable farmers. It is very unfavorable for the growth of vegetables in the later stage, which requires us to be more careful when purchasing seedlings.

But what kind of seedlings are good seedlings, and whether there is a standard, it is difficult for everyone to grasp. Just seeing the leaves are dark green and there are no disease spots, they think such seedlings are good seedlings. But often the seedlings look fine, but the grown trees are uneven in height and disease-prone. So how should we judge whether the seedlings are good or bad?

Finally, look at the leaves.

Some vegetable farmers think that the dark green leaves are good seedlings, but if the leaves are dark green, it means that the early stage is over-controlled, and such seedlings are slow after planting, which has a great impact on the yield, while the normal leaves should be light green. stretch. Look at the leaves without disease spots, eggs, yellow-green spot disease, etc., and avoid buying diseased seedlings. In addition, if the leaves are deformed, it is mostly pest damage, and should be carefully observed to prevent pests from being brought into the shed.
