The heart of the dish is also known as the vegetable dish. The flowering and tender leaves of the cabbage are edible, the quality is crisp, the flavor is good, and the nutrition is rich. The cultivation techniques are as follows: First, cultivate strong seedlings: 1. Variety selection: The late-ripening variety Qingliuye, which has strong cold resistance and main side moss, is selected. 2. Sowing: In the first ten days of October, use greenhouse seedlings and nutrient soil preparation: mix 1200 kg of fertile soil and 800 kg of decomposed round fertilizer, add 3 kg of diammonium and mix well, and spread on a 20 m2 seedbed for use. After leveling the seedbed, pour the bottom water, cover the film, and bake for 3-5 days to increase the temperature. The seed amount of one mu of land is 50g, the dry seed is broadcast live, and the fine soil is covered by 1cm after sowing. 3, seedlings: After the emergence of the seedlings, remove the small arch shed on the seedbed, reduce the humidity, and appropriate the wind before the seedlings to strengthen the seedlings to exercise at low temperature. Prepare the seedlings for about 15 days before the seedlings (the method is the same as the seedbed), and the seedlings should be selected on a clear day, and the seedlings are squared at 10 cm. 4, seedling management: seedling temperature management should be carried out in stages: germination period to promote the emergence of seedlings quickly, the daily temperature should be maintained at 25-30 ° C, night temperature is not lower than 15 ° C, slow seedling period after emergence, daytime temperature Maintain at 20-25 ° C, night temperature 15 ° C, gradually reduce the temperature after slow seedling watering, maintain 15-20 ° C during the day, night temperature 10 ° C or more. 4 to 5 days before planting, the seedbed is poured once, and the next day, the seedlings and seedlings can be dug. Second, colonization: Before planting, the base fertilizer should be applied, 5000kg of high-quality rotted ring fertilizer, 30kg of phosphorus-potassium compound fertilizer, 20-30 days after sowing, and 5-6 pieces of true leaves can be planted, the planting density is 1822cm, and the shed is fixed before planting. To increase the ground temperature. Third, the field management after planting: 1. Water and fertilizer management: On the basis of planting water, 7~8 days after planting, the seedling water should be poured again, and weeding and weeding should be carried out to promote the growth of roots. After the seedlings are planted, the water should be properly controlled from the leaf cluster growth stage to the current bud. Into the vegetable growing period and harvesting period, it is necessary to increase the number of watering to maintain the soil moisture. In the whole growth period of the cabbage heart, it is necessary to topdress 1-2 times, and apply urea 10~15kg per mu. 2. Temperature management: Protecting the production of cabbage, temperature management is very important. The seedling period after planting is kept at 20-25 °C during the day and 15-20 °C during the night. The temperature is maintained at 18-22 ° C, and the night temperature is 12-18 ° C. From the bud to the harvesting period, the daily temperature is maintained at 15-20 ° C and the night temperature is 10-15 ° C. In production, the time required for the removal of the mat and the length of the vent should be adjusted according to the temperature requirements of the development of the cabbage. 4. Harvesting: The standard for harvesting cabbage is: harvesting "Qikouhua", that is, the height of the flower bud is roughly the same height as the apex of the outer leaf, and the flower bud is about to open.

Kojic acid is an organic compound with molecular formula of c6h6o4 and molecular weight of 142.11. Colorless prismatic crystal. It is used as Antioxidant and anti radiation agent. It is used in the field of cosmetics. In human skin, tyrosine is catalysed by tyrosinase, and then oxidized and polymerized with oxygen free radical to synthesize melanin. Kojic acid can inhibit tyrosinase synthesis, so it can strongly inhibit the formation of skin melanin, and is safe and non-toxic, and does not produce leukoplakia sequela. Kojic acid has been incorporated into make-up water, facial mask, emulsion and skin cream. It can be used to treat freckles, senile plaques, pigmentation, acne and other high-grade whitening cosmetics effectively.
