Pollution-free Vegetable Cultivation Technique Tutorial: Detailed Explanation of the Latest Planting Methods
Vegetables are a major planting project in China. As people's requirements for food become increasingly strict, improving vegetable quality has become ever more important. Therefore, pollution-free vegetable cultivation has gradually become the main cultivation method for vegetables. Pollution-free cultivation can effectively improve vegetable quality and enhance the food safety of vegetables. So how should pollution-free vegetables be cultivated? Let's take a look together below!
1. Environment Selection
The first task in pollution-free vegetable cultivation is to choose a good planting environment that meets the production requirements of pollution-free vegetables. The most important thing for the planting environment of pollution-free vegetables is to stay away from pollution sources such as urban areas and factories. Ensure good drainage and irrigation capacity, and that water quality meets planting requirements. The planting soil should be relatively deep and soft, with sufficient fertility and good structure. Control the soil area well according to the planting scale, and ensure that crop rotation can be carried out according to the planted varieties. Then do a good job of soil preparation, improve the natural environment, and create a good growing environment for the vegetables.
2. Planting Management
Then we should choose a suitable planting variety according to the soil type and planting region, then select excellent seeds and disinfect the seeds. Control the sowing time and sow at the right time to improve the growth capacity of the seedlings. Then do a good job of transplanting management according to the growth habits of the vegetables. Strengthen field management by carrying out a series of tasks such as intertillage weeding, trellising and pruning. Control humidity and provide ventilation according to weather changes, but specifically it still depends on the vegetables' requirements for the environment, and adjustments should be made flexibly.
3. Reasonable Irrigation
The intensity and frequency of irrigation should be reasonably adjusted according to the soil type and soil moisture. For example, sandy soil has relatively poor water retention capacity, so it needs frequent watering; on the contrary, clay soil requires good drainage work. Then irrigation should also be carried out according to the weather and the growth of the seedlings. In hot weather, water more; on the contrary, water less or not at all. If the leaves are bright and shiny, water less; if they are wilted, water more. However, no matter what kind of vegetable it is, it is not suitable to water at noon, to prevent a high-temperature and high-humidity environment from causing pests and diseases.
4. Fertilization Methods
No matter what kind of vegetable is planted, sufficient base fertilizer must be applied. Base fertilizer is the key to ensuring the healthy growth of vegetables. The base fertilizer is mainly composed of decomposed farmyard manure, but the type of fertilizer should also be chosen well according to the planted variety. For example, for cilantro and lettuce, it is not suitable to use farmyard manure. Then when topdressing, although nitrogen fertilizer should be appropriately supplemented, attention must be paid to the amount, and it must not be excessive. Avoid excessive nitrogen fertilizer causing vegetables to grow excessively, reducing field aeration, consuming too much nutrition, and also leading to a decline in yield.
The above is a brief introduction to pollution-free vegetable cultivation techniques. Pollution-free cultivation will definitely become mainstream in the future. Its food safety is higher, and its cost is relatively low, so its economic benefits are quite considerable. That is all for today's introduction. This article is for reference only.
