The seedlings produced by the nursery plant grow in the same shape and look more robust. Many farmers have checked the quantity and accepted it, but they have neglected some details of the seedlings. As a result, the seedlings have problems such as wilting, leaf spots and even dead trees after planting.
At this time, many vegetable farmers doubted whether there was a problem with the seedlings sent from the nursery. At this time, the problem has already occurred, and the loss has already been caused. Even if it is determined to be a problem of the nursery factory, partial compensation is only a slap in the face. In fact, as long as you carefully identify, many problems can be avoided. During the nursery process, there are many factors affecting the growth and development of seedlings, such as temperature, water and fertilizer, pests and diseases, etc., if not pay attention, it will easily lead to seedling damage. Moreover, most of the current seedlings have to go through 30 days from sowing to sale, and the fungicides added to the seedling substrate have long been ineffective, which is when the seedlings are susceptible to illness. If the nursery plant does not pay attention to disease prevention, it is likely to carry some germs or have already developed disease, leading to a large area of ​​disease after colonization. Here, once again remind the vegetable farmers that if you want to avoid losses and disputes, you must strictly control when you receive the seedlings.
