What are the edible effects of kohlrabi? The kohlrabi is also known as mustard and broccoli. It has the shape of ellipse, oval, inverted egg, lanceolate, etc. It is eaten by the underground roots. The meat is firm and the quality is good. It is suitable for frying or pickling. . The kohlrabi has the effects of detoxification, swelling, refreshing, and eyesight. It is suitable for the elderly and habitual constipation. Today, Xiaobian talks about kohlrabi planting technology and water and fertilizer management.
First, the variety selection
The kohlrabi variety is dominated by common species and giant horses.
Second, the sowing period
1. The kohlrabi can be broadcast live or transplanted, and most of the production is live.
2, kohlrabi planting requirements are more stringent, sowing too early, high temperature, prone to viral disease and immature convulsions; sowing too late, when the low temperature, kohlrabi grows slowly, assimilated organs are small, the roots are not easy to expand, low yield.
3. When sowing in the soil dry condition, it is necessary to dig a hole about 2cm deep at a certain row spacing on the kneading surface. After sowing, cover the seed with the decomposed and chopped farmyard manure and fill it with water.
Third, reasonable close planting
Live broadcast mode: 25,000 strains are reserved for common species, transplanting density is 25cm×15cm, and 20,000 plants are planted in acre; Malong species: transplanting density 45cm×50cm, 3000 plants per mu.
Fourth, fertilizer management
1. The sauerkraut is transplanted and planted immediately after transplanting. During the growth and development period, the thin high-quality organic fertilizer and the NPK fertilizer are applied. Generally, it is applied once every 15-20, and it is continuously applied 3-5 times, each time for each acre. 5-10 kg of NPK fertilizer, combined with thin manure and water fertilization.
2. The underground roots are rapidly inflated, and the application of potassium dihydrogen phosphate is 3 to 5 kg per mu. Each 7 to 10 days, 800 times of vegetable-specific high beauty is sprayed, and even sprayed 3 to 5 times.
3. After the seedlings of the kohlrabi seedlings are planted, the nitrogen and phosphorus fertilizers are applied once every 7 to 10 days, and the application is carried out continuously for 2 to 3 times. Each time, 8 to 10 kg of urea per urea and 5 to 6 kg of diammonium phosphate are used, and the water or biogas slurry may be exchanged. The manure water of the decomposed man-made animal is 60-80 times and then drenched.
V. Pest control
1. Control of aphids and virus diseases in the seedling stage of kohlrabi: Foliar spray 1 to 2 times 2500 times pure, 800 times virus A mixture.
2, swelling period of yellow sassafras, root rot prevention: foliar spray 1500 times liquid agricultural music, 2500 times liquid carbendazim mixture.
3, kohlrabi soft rot prevention and control: use 70% methyl thiophanate WP 1500 ~ 1000 times liquid, or Shigao water dispersion granules 1000 ~ 1500 times liquid spray control.
4. Control of larvae and cabbage larvae: use Jinyun biological insecticide 1.5kg/hm2, or 1.8% harmful emulsifiable concentrate 300~450mL/hm2 to spray 750kg of water.

Green and functional cosmetics are more and more favored by people. As plant extracts are more and more widely used in cosmetics, more and more varieties are used. Compared with traditional cosmetics, cosmetics prepared with plant extracts as active ingredients have many advantages, such as overcoming the shortcoming of traditional cosmetics relying on chemical composite products, and making the safety of products higher; Natural components are more easily absorbed by the skin, making the effect of the product more significant; Functional more prominent, etc. Therefore, the application of plant extracts in cosmetics is the inevitable trend of market development. In addition, plant extracts have many obvious advantages, such as wide source and targeted mechanism of action. Especially with the progress of modern extraction technology and analysis technology, its effective ingredients and related mechanisms of action have been gradually discovered and confirmed by people, in the sunscreen, whitening, anti-aging, sterilization and other aspects of significant efficacy, can be widely used in various cosmetics. Therefore, the application prospect of plant extracts in cosmetics is very broad.
