Cultivation season
In all parts of Shandong, kale can be cultivated in spring and autumn. Spring hoe is planted in February-March, and the harvest period is from May to June; autumn raft can be sown in July-August, and harvesting period is from October to November.
2. Cultivate seedlings
The strong seedling of Chinese kale is a seedling with appropriate development, thick stems and large and thick leaves. The favorable environmental conditions for creating seedling growth are the basis for cultivating strong seedlings. In summer, nursery should adopt shading and cooling measures; when winter and spring are cold, plastic film can be used to cover seedlings, and fertilizer and water management can be strengthened to promote seedling growth. Seedling age 20 to 30 days, with 5 to 6 leaves, you can colonize.
3. Colonization
The condition of the soil is not strict, and all kinds of soil can be cultivated, but the fertile loam is ideal. The mustard spring planting should use sorghum and cover the mulch, and the autumn planting should be flat. Planting density, early maturity mustard (20 ~ 25) cm (30 ~ 35) cm is appropriate, medium and late maturity type is 30 ~ 33 cm square is appropriate.
4. Field management
After the plant is slowed down, the soil should be ploughed in time to promote the rapid growth of the root system. In the early stage of Chinese kale, it mainly promotes the growth of leaves, and provides sufficient nutrients for the differentiation and development of flower buds. When topdressing, it should supply sufficient nitrogen and appropriate amount of phosphorus and potassium. In the process of flower bud formation, in addition to supply foot In addition to the amount of nitrogen nutrition, phosphorus and potassium fertilizers must be added. Usually after slow seedling, 15-20 kg of urea per mu, and 10 kg of nitrogen, phosphorus and potassium compound fertilizer; after the plant is budded, the second top dressing is applied, and 10 kg of urea is applied to the mu, and the compound of nitrogen, phosphorus and potassium is combined. Fertilizer 15 ~ 20 kg; after the main harvest, and then apply a fertilizer, the amount of application refers to the second amount of fertilizer. The ability of kale to withstand drought and suffocation is poor, and water management is extremely important. In the blade growth period, it is advisable to see dryness. The flower bud formation period should keep the soil moist, and the relative humidity of the soil should be 80%-85%. Pay attention to drainage when it rains to prevent stains.
5. Harvest
The kale is a high-quality product with large stems, long internodes, and few leaves and tender leaves. In addition to harvesting the main scorpion, the side sill is also an important part of the production. In order to promote the occurrence of side squats, prolong the harvest period and increase the yield, the main flower buds should be harvested in time when they reach the same height as the leaves. Keep 4 to 5 green leaves when harvesting. After the main harvest, strengthen the management of fertilizer and water, and also harvest 3 to 5 side squats. The yield per mu can reach 1500-2500 kg.

Plant extracts refer to a class of substances derived from plants that have one or more biological functions. Can be separated by physical and chemical extraction of one or more effective components formed by natural products.
There are many kinds of plant extracts. At present, natural plant extracts mainly include essential oils, saponins, alkaloids, polysaccharides, polyphenols, flavonoids and so on. According to the biological activity, it can be divided into antioxidants: grape seed extract, green tea extract, pine bark extract, etc. Immune modulators: ginseng extract, gynostemma pentaphyllum extract, Ganoderma lucidum extract, etc. Improve cardiovascular function: ginkgo biloba extract, lotus seed heart extract, rhodiola extract, etc. Sedative: valerian extract, hop extract and so on.
According to their own characteristics in the market application of plant extracts can be roughly divided into six categories: coloring, seasoning, medicinal, health, dietary supplements and feed additives. Natural plant pigments refer to pigment components in roots, stems, leaves, flowers, fruits and bark of plants, such as turmeric, sappanwood, indigo, safflower, black bean and green walnut peel. Natural plant pigments are widely used in food, textiles, cosmetics, medicine, leather industry, printing and dyeing and other industries.
Plant extracts are rich in ingredients that can effectively stimulate the senses, such as sweeteners and volatile substances. Natural sweeteners, such as stevia glycoside and grosvenin, are popular new sweeteners. They are not only sweet, but also ideal substitutes for sucrose. Essential oils are concentrated volatile substances that are commonly used in the preparation of fragrances and are widely recognized in plant extracts.
Contained in the plant extracts of saponins, alkaloids, polyphenols, flavonoids and other ingredients are widely study has many biological activities, such as antioxidant, antibacterial, anti-inflammatory, improve animal production performance, antivirus, enhance immunity, etc., for human and animal health has the effect of nots allow to ignore, and the development of its pharmacology and health care function has become the main trend of plant extracts.In addition, as a dietary supplement, it is one of the main applications of various plant extracts. Such as oligosaccharides (oligosaccharides, oligosaccharides, oligosaccharides, galactose, etc.) dietary fiber, soybean protein, dietary fiber, wheat albumin, L-arabinose, sugar alcohol (xylitol, malt heavy sugar alcohol, sorbitol, etc.) and other natural plant food additives have been widely used in the food health care market. Many plant functional ingredients with anti-inflammatory, antioxidant and bacteriostatic properties are also commonly used as substitute anti-bacterial products. The application of green feed additives in livestock and poultry production has been vigorously developed, such as green tea polyphenols extract, pine bark procyanidins extract and polyanthocyanidins extract.
Due to the changes in lifestyle, working mode and consumption mode, more consumers are pursuing the life concept of "big health". The so-called "big health" refers to a concept of whole-process, comprehensive and total factor care for people's life around the basic necessities of life, life, old age, illness and death. It not only pursues individual physical and physical health, but also pursues mental, spiritual, social, environmental and family health. In the era of "great health", natural plant-based health products are the core and the key material basis.
With increasing attention to the food and drug safety, from natural plant in the development and utilization of the active ingredient is becoming more and more attention, a large number of food safety, have certain curative effect function of plant extracts have been used as raw materials in a variety of ways into functional food nutrition and health food has entered people's lives, and will play a more and more important role.
And more and more new research new discovery, predicts that the plant extract industry chain will have more members to join, there will be more business opportunities. The future domestic plant extract market will stride forward gradually to mature period!
