Li Caiyun, a peasant in Baimiao Township, Qixian County, asked: As people increasingly seek to return to nature, the wild food has become a “sharp scent†on people's dining tables. If large-scale and specialized planting is required to satisfy the demand for wild vegetables, how should domestication be cultivated?
First of all, it is timely picking, which is also the basis for the cultivation of artificial domestication. According to different wild vegetables classified seed collection, make a mark. For wild vegetables growing in spring, because of flowering, fruiting and ripening, and many easily scattered seeds, seed collection should be performed at different times to avoid delays. Summer wild vegetables must be pre-marked and protected for plants that need to be harvested to avoid vandalism.
Secondly, it is to do a good job of fertilization and sowing of soil preparations to prepare for the expansion of wild rice varieties. The seeds of wild vegetables are generally small seeds, so we must do it carefully to make a good seedling. To promote growth and development, a certain amount of fertilizer is applied before soil preparation. Organic fertilizer is the best. In order to master the sowing time, it is required that spring wild vegetables be planted in late autumn and summer raw vegetables should be sown in spring. For perennials, roots can be excavated at any time and planted in fields. The sowing of wild vegetables is generally carried out in the form of sowing, so that the seeds of different single plants of the same species are planted in different areas for observation and selection. Before the planting, we must make good oysters, then we should sow the soil. In the summer, we must pay attention to shade.
Finally, it is to do field management and comparative observation. After the emergence of wild vegetables, they should be seedling and weeding; they should be observed during the feeding period to compare the morphology, color, texture, and food quality of the wild vegetables; determine the seedlings and make good marks; Management to better promote their reproductive growth; storage and marking after harvesting make preparations for future expansion.
