Five tips for seedling management of autumn planting vegetables

After entering the autumn, it is another peak season suitable for growing vegetables. At this time, the temperature will drop and the humidity will be reduced. It is more suitable for vegetable growth, and no diseases will occur. Although some vegetables are not planted in this season, they still need to be grown. Many vegetables are suitable for fall growth. In autumn, there is still a small spring, which is a period of short-term recovery. Now let's take a look at how to manage vegetables grown in autumn.

1. The organic manure needs to be fully decomposed before planting.

When a large amount of livestock and poultry manure is used as base fertilizer, it should be composted and decomposed in advance. Every year, the phenomenon of burning seedlings and burning roots is not uncommon because the manure is not well decomposed or used directly before it is decomposed. Especially this year, the temperature is high, the soil temperature is high, and the impact of using immature manure is even more obvious. Adding a decomposing agent to the manure in advance, or applying the manure to the soil in advance, combined with the high temperature and stuffy shed work, can complete the decomposing process, saving time and effort, and the effect is better.

2. Moisture fertilizer.

Underground vegetables such as root and stem need continuous watering and cannot be dry. Although the sun is not strong in autumn, there is not much rain, so watering is required. But don't water too much at one time, it is easy to crack the roots, and it is easy to cause root rot. Fertilization should also be combined with watering to adjust the concentration of the soil solution. Fertilizer mainly applies nitrogen fertilizer to leafy vegetables. The effect of using farmyard manure is comprehensive.

3. Pay attention to the depth of colonization.

When planting, the exposed or seedlings should be consistent with the surface, and do not bury them for cultivation. In the continuous high temperature weather this year, if the soil is buried too deep during planting, the base of the stem is buried with soil, the ground temperature is high, and the soil is in a high humidity environment after watering, which is easy to cause diseases such as stem rot and blight.

4. Watering and paddling.

Under the influence of high temperature weather, watering still adheres to the principle of "small water and frequent watering", and determines a reasonable amount of watering and watering interval according to weather changes, plant growth and soil humidity. It is recommended to apply rooting agent fertilizers with water during watering to stimulate root growth at the seedling stage and promote strong root groups. After watering, cultivating and hoeing should be done in time to remove soil compaction, maintain soil moisture, and ensure smooth root breathing.

5. Pest control.

Under high temperature weather, vegetables are slow to seedlings, and their growth is poor, and the resistance of plants to pests and diseases is significantly reduced, which is more likely to lead to the infection and damage of pests and diseases.

6. Choose suitable cultivars.

In the early stage of vegetable seedling, the temperature is high, and the water changes vary greatly, and in the later stage of growth, it is in the stage of low temperature and lack of light. Therefore, cultivars with wide adaptability, disease resistance, cold resistance and high yield should be selected in the selection of varieties.

Prevent damage caused by high temperature and rainstorm in seedling stage: high temperature and rainstorm will inhibit the growth of vegetables in seedling stage, resulting in frequent occurrence of pests and diseases. When raising seedlings, the application of shading nets and insect nets can effectively prevent high temperature, rainstorm erosion and pest damage.
