After planting the vegetables, the yellow leaves of the new plants and the wilting of trees were observed. The main reason was that the roots were injured due to improper management after planting. Should do the following work:

There are two main causes of root damage caused by rooting in wintering vegetables. One is that some vegetable agricultural fertilizers are unreasonable, one-off usage is excessive, or incompletely cooked manure is used to cause burning of vegetables. At this time, water should be poured as soon as possible to dilute the soil. Concentration of fertilizer in the middle; Second, excessive rooting caused by excessive watering at low temperature. At this time, ventilation should be strengthened to reduce the humidity in the greenhouse. In addition, it should be combined with cultivating loose soil to increase the permeability of the soil and promote the emergence of new roots of vegetables. Roots and cytokinins can be applied to plants that are particularly severely injured.

While keeping the roots, raising leaves is also an important measure to accelerate the recovery of the plants. First of all to supplement the nutrition of the leaves. After the vegetable roots are injured, the ability to absorb nutrients weakens, and the plants are bound to suffer from iron deficiency and zinc deficiency symptoms. It is possible to spray 2-3 times of foliar fertilizers containing zinc and iron, and also to spray mitogen-mixed nucleotide foliar fertilizers. . In addition, we must pay attention to the prevention and treatment of leaf diseases.

The vegetable roots of the heads and leaves were injured, and the top tip must have been shrunk for a long time. Therefore, it is recommended that the vegetable growers should take timely measures to resolve them. It can be sprayed with foliar fertilizers and plant growth regulators that have the effect of lifting the leaves and leaves, such as love-over or brassinolide.

Greenhouse Garden Hydroponics

In a hydroponic system, plants are placed in nutrient-enriched water. Mediums such as gravels, sand or vermiculite can also be used. Thus plants which are placed in the water absorb the nutrients very easly. When the nutrients from the water starts finishing , water is recycled or additional nutrients are added.
