Vegetable planting techniques in open air
Varieties with resistance to diseases and insect pests, high quality, high yield and good stress resistance should be selected for open-air planting, and soil preparation and fertilization should be applied before sowing. Then it is necessary to optimize the planting structure, apply soil fertilization technology, and do a good job in the comprehensive control of diseases and insect pests. In addition, due to the wide variety of vegetables that can be grown in the open air, special attention should be paid to some management details. For example:
1. Ginger
When planting ginger in the open air, we should pay attention to avoid excessive application of nitrogen fertilizer, resulting in imbalance in nutrient absorption, and avoid soil roots, leading to the spread and spread of disease.
two。 Potato
Potatoes should soak the seeds and germinate before planting, either by natural germination or gibberellin germination; in addition, topdressing and soil cultivation are also particularly important, generally in the germination stage (before and after 12 leaves). Topdressing can be used in combination.
3. Chili pepper
The pepper should be soaked in clean water for 3-4 hours before sowing, then soak the seeds with root rot or agricultural streptomycin in proportion, and then sow the seeds after washing. Generally speaking, the renewal is not large in the seedling stage, and it is mainly concentrated in the fruit stage.
4. Other attention
The planting time of different vegetables is different, such as cauliflower sowing from September to November, stem sowing with mustard in autumn, celery planted from early July to December, gourd sowing in February, and so on. When planting open-air vegetables, we should sow seeds timely according to the growth characteristics of the crops.
Although most open-air vegetable planting techniques are similar, there are still some differences in sowing time, fertilization time and so on. We should determine it according to the actual situation, and do not apply it blindly.
