Fertilization of Chinese cabbage high-yield planting technology

Chinese cabbage is one of the most common leafy vegetables in people's daily life. If the good yield of management is considerable, but because of the large amount of fertilizer needed for Chinese cabbage, if the lack of phosphate fertilizer and potassium fertilizer in Chinese cabbage will lead to problems such as unclearness, etc. Although cabbage is a leafy crop, it has the characteristics of high yield and high fertilizer. However, Chinese cabbage is not a vegetable that only needs nitrogen and does not require phosphorus and potassium. In the cultivation, only nitrogen is applied, and the lack of phosphorus and potassium may cause a problem of unsatisfactory inclusion. Partial application of nitrogen fertilizer not only has low yield and quality, but also leads to poor core.

The unclearness of Chinese cabbage is caused by improper management of fertilizer and water. Partial application of nitrogen fertilizer, phosphorus and potassium nutrients will cause unsatisfactory concoct; the cabbage in the rosette period should control water and control nitrogen, lay a good foundation for the heart, premature watering and nitrogen application will cause unintentional. From the perspective of the whole growth period of Chinese cabbage, it is necessary to pass the three periods of seedling stage, rosette stage and core period. The nutrient absorption of Chinese cabbage seedlings is less, only 10%, and the rosette period accounts for 30%. Water control fertilizers, especially nitrogen fertilizers, allow the leaves of cabbage to grow slowly, which is also called the seedling stage.

Do not let the water too much to cause the leaves to grow and erect, but should make the leaves grow like the rosettes, the leaves are tight and flat, and the ball can be tight, the yield is high, the quality is good, and the leaves are prematurely irrigated during the rosette period. And the application of nitrogen will cause the leaves to be long, the leaves are big and the problem is not true. When the Chinese cabbage is watered, the quantitative fertilizer is dissolved in the ditch, and the water is infiltrated into the soil around the root system. This is also a relatively simple, labor-saving, time-saving, and labor-intensive fertilization method. It can be used as the preferred method of topdressing when there is a serious deficiency of fat in a large area.

In addition to urea, potassium dihydrogen phosphate, potassium sulfate, potassium nitrate, compound fertilizer and other commonly used fertilizers, fertilizers used in foliar spray fertilizers have a certain effect on the market for fertilizers containing a large amount of elements and various Amino Acid components. However, the nutrients needed for the growth and development of vegetables mainly come from the base fertilizer and other top dressings. Foliar spray fertilizer can only be used as an auxiliary fertilization measure.

How to apply fertilization for Chinese cabbage cultivation? In the middle and late growth period of Chinese cabbage, fertilization measures for embedding can be adopted. It is necessary to pay attention to safety when applying. It is easy to damage the root system when it is too close to the root. To prevent negative effects, it is necessary to timely water the fertilizer after burying. The concentration is lowered to improve the fertilizer efficiency. In addition to paying attention to timely topdressing, Chinese cabbage management can be combined with pest control for multiple foliar spray fertilizers. The fertilization method has a small dosage, a quick fertilizer effect, and can avoid nutrients being fixed by the soil, and is a labor-saving and effective fertilization method.

Plant extract

Plant extracts are based on plants as raw materials. According to the needs of the use of the final product extracted, through a physical and chemical extraction and separation process, one or more effective ingredients in the plant are obtained and concentrated, without changing the effective ingredients. The product formed by the structure.
1. According to the content of active ingredients, it can be divided into three types: effective monomer extract, standard extract and ratio extract;
2. Divided into glycosides, acids, polyphenols, polysaccharides, terpenes, flavonoids, alkaloids, etc. according to ingredients;
3. According to the product form, it can be divided into vegetable oil, extract, powder, lens, etc.
4. According to the purpose, plant extracts can be divided into natural pigment products, traditional Chinese medicine extract products, extract products and concentrated products.
There are several classifications of some of the best-selling plant extracts in the world. For example, Rhodiola, Ginkgo biloba, Ginseng extracts are used in the field of brain strengthening, nourishment, and prevention and treatment of Alzheimer's; polypeptide extracts of green tea, Citrus aurantium, apple, and bitter gourd Used in weight loss, lowering blood sugar and preventing diabetes; Paclitaxel, tea polyphenols, theanine, bioflavonoids, such as lycopene, anthocyanins, etc. are used in natural anti-cancer fields; licorice, garlic, astragalus, soybean extract Used in the field of human immune system.
