Dead trees, nematode occurrence, preferably chitin + biological inoculants
After the vegetable is planted, diseases at the seedling stage are high, and dead trees are serious, which are the primary factors affecting vegetable production. Therefore, vegetable farmers should pay attention to top dressing at the seedling stage on the basis of making good base fertilizer fermentation and high temperature stuffy sheds to improve stress resistance, inhibit the proliferation of pathogenic bacteria, and reduce the occurrence of disease infection.
In terms of bacteriostasis and disease prevention and reduction of nematodes, vegetable farmers can give priority to the combination of chitin + biological inoculants, which has a significant effect.
Deteriorating soil compaction, heavy humic acid + biological agent is the first choice
Improving the soil, reducing pathogenic bacteria, salt and other harmful substances in the soil, improving the soil structure, and creating an environment suitable for root growth are the most effective means to promote the robustness of the root system and increase the resistance of vegetables.
In recent years, problems such as soil salinization and compaction have become increasingly serious, which have become an important factor restricting the growth of vegetables. If the soil problems are more serious after vegetable planting, the best mitigation measure is to flush high-quality humic acid + biological inoculants.
Weak roots and small stems
Preferred alginic acid + amino acid
Once the vegetables have been planted and they encounter poor plant growth, vegetable farmers can start with planting and increase the use of alginic acid and amino acid fertilizers.
The use of alginic acid fertilizer can help vegetables build a strong root system and improve their absorption and utilization of soil nutrients, water and gas. In addition, the active substances such as sodium alginate in alginic acid also have the effects of improving soil structure, breaking soil compaction, and delaying salinization.
Amino acid fertilizers can directly supplement various amino acids and other advanced nutrients needed for root growth and development, and help promote rapid root regeneration.
After the vegetable is planted, once phytotoxic or fertilizer-damaged plants appear, the effect of using alginic acid + amino acids is the most obvious.
