The developed root group is the guarantee for the disease resistance and resistance of vegetables, and the foundation for the stable and high yield of vegetables in summer. However, in actual production, the series of problems such as shallow roots, weak roots, roots and roots are often caused by environmental conditions, soil conditions, watering and fertilization, which limits the growth of summer vegetables. How to make the summer vegetables maintain a developed root system?
1. The cultivation method should be reasonable. Vegetables are divided into two types: ridge planting and mullet cultivation. In the sheds with high groundwater level, soil viscosity, and soil-borne diseases, ridge planting can be used. In the shed room with few of the above conditions, the method of flat cultivation can be adopted.
Summer vegetables are not recommended to colonize the bottom of the ditch or to colonize too deep. Taking the summer tomato as an example, it is best to use flat cultivating, which is conducive to watering, does not cause soil drought, root water shortage, and does not cause excessive ground temperature, affecting root growth.
2. Shorten the slow seedling period and promote the roots to tie down. When planting, the vegetable grower can use the antibacterial 968 蘸 蘸 蘸 蘸 root, prevent disease and promote roots. After the seedlings are planted, the planting water should be poured and thoroughly poured. After the planting water and the seedling water are poured, the water should be properly controlled to promote the root system. When watering, the fertilizers such as bacteria, chitin and alginic acid can be applied and rooted. Roots. In the early stage of vegetable growth, the sputum should be taken as an important management measure. Generally, at least two strokes should be made before the results of the seedlings. If the soil is heavy, the number of strokes is even more.
3. Use nutritious roots. Root maintenance is a systematic project, and it is necessary to pay attention to the maintenance of roots after planting vegetables. In summer, many vegetable farmers no longer use rooting agents. In fact, rooting agents are needed in the summer high temperature season to increase the activity of roots. When selecting rooting agents, non-hormone-type rooting agents such as chitin, amino acids, and alginic acids can be used to not only protect the soil and roots, but also balance plant growth.
