Internship journalist, chinese agricultural news network, agricultural science and technology
Wang su quan, yuyang city, henan province, asked me about three acres of chinese medicine last year
Question: on this question, the journalist interviewed yonghai, a researcher at the northwestern university of agroforestry
1. Selection of plots. The white arts are cold-resistant, and it is desirable to choose the cool areas of the climate, the soil is permeable and the sandy and fertile plots of land. Soils that are too sticky, water-prone or less fertile should not be planted. It is not appropriate to use white art as a pre-selection field for tobacco, peanuts, oilseeds and other ground root crops, for example, if the disease is serious。
2. Fertilizing the whole area. General base fats can be selected for organic, urea, phosphorus, potassium, etc., and can be applied as required by the product. The soil needs to be finely flattened to more than 1 m wide in order to facilitate drainage. Cultivation. During the winter to spring of the following year, the transplantation will take place from late december to early january, but not later than the clarity. The planting is better for those who didn't smoke leaves, who grew strong, whose roots were small, and whose almonds were small. (c) cultivation, cutting off the stubble during planting, and planting seedlings into the gutter and lumbering up at a distance of 25 cm. Cultivation should not be too deep. It should be covered with mashed ash and ground and flatted, with a slight crackdown on both sides。
4. Scientific fertilization. After seedlings are produced, they take about three months to pick up the bud, which is a booming period for the upper and lower parts of the plant, which requires early application and appropriate application, with particular attention to phosphorus and potassium fertilizer. The white root enters a period of expansion, which lasts about two months and requires a new application of nitrogen fertilizer. Nitrogen fertilisation is then applied to a small amount of seedlings, with a small amount of phosphorus fertilisation and potassium fertilisation, to avoid a shortage of fertilizers, in order to promote robust growth and root expansion. 5. Water management. The white arts prevent the wetting of water and must be careful to open trenches in a timely manner, so that the rain does not accumulate water in the fields and so that the fields are not wet enough to survive the disease. In the latter stages of white art growth, especially in the period of expansion, proper moisture is required, which should be irrigated in time for drought。
6. Remove buds in due course. Apart from the plant, the remaining plants need to be removed from the bud in due course. The white arts plant began in late june, and by mid-july it entered its prime stage, requiring several pick-ups. The pick-up takes place in the sun, squeezing the head, picking the head, stabbing the leaf, shaking the roots and picking the head in the rain。
