Watermelon sweetening technology

1. Apply sweetened fertilizer. With 0.75kg of saccharin, add appropriate amount of water to dissolve and boil, soy beans continue to cook for 3 hours, so that sugar infiltrated into the expansion of soybeans made of saccharine beans, and then mixed with 10kg wheat bran, 10kg rice bran, 0.5kg diammonium phosphate, 18kg ash mix It becomes a sweet fat. When female watermelon is open, 0.2-0.25kg per hole is applied. This method can increase the sugar content of watermelon by more than 40%. 2, topdressing vegetable oil. When the watermelon grows to the size of a fist, use a wooden stick with a diameter of 1.5cm to dig a 12cm deep hole 2cm away from the main root, then add 3-4 drops of vegetable oil, then seal it tightly with soil and pour for 3-5 days. 1 water can increase the sugar content of watermelon by more than 10%. 3, the application of watermelon. This method can make the seedling period 1 day earlier, the emergence rate increased by 10%, the guaranza rate increased by 7-10%, increase production by 7-15%, increase the sweetness by 0.7 degrees. The method is: using 200-300 times of watermelon melon, three times of spraying in watermelon seedling period, sitting period and expansion period. 4, the application of organic fertilizer. Watermelon sits about a week, digging a hole 10cm away from the main stem, each chicken, rabbit manure or cow manure and cake fertilizer each 50 grams, water after sealing the soil. 5, spray superphosphate. Use super-calcium phosphate 1.5-2kg, flush 10kg, mix well, stand for 24 hours, take clear liquid, spray 1-2 times after watermelon is in fruit setting and bowl size, generally can increase 8%, sugar content can be increased. 0.6-0.8%. 6, spraying potassium dihydrogen phosphate. When the watermelon grows to the size of the egg, it can be sprayed once every 7 days with a 0.3% potassium dihydrogen phosphate solution, which can increase production by 10-20% and increase the sugar content by 0.5-1.5 degrees. 7, spraying plant ash. With fresh grass ash 2.5-3kg flush 50kg, stir and soak for 8-12 hours, take clear liquid spraying on the leaf surface, can increase production by more than 10%, sugar content can be increased by 0.5 degrees. 8, see pulse melon. Folding melons should be carried out during the expansion period. Turn the watermelon along the melon and turn it 180 degrees in the direction of the melon vein. Turn it once every 7-8 days and turn it twice. When operating, hold the top of the melon in one hand and hold the melon tail in one hand. Lightly tap melon. Fold melon should pay attention to the following two points: First, it should be carried out at noon on sunny days or in the evening to prevent the guaranty leaves from breaking off. The second is to flip the melons in the same direction each time, and must not be strongly twisted. It is advisable to turn the melons over one-third each time.

Pharmaceutical intermediates

Drug Intermediates -Pharmaceutical intermediates: A material that is produced during a process step of the drug substance and must undergo further molecular changes or refining before it becomes a drug substance. The intermediates can be separated or not separated.

Active Pharmaceutical Ingredient (APIS)(or Drug Substance) : Active Pharmaceutical Ingredient (API)(or Drug Substance) : Any substance or mixture of substances intended to be used in the manufacture of pharmaceutical products and, when used in pharmaceutical products, to be an active ingredient in pharmaceutical products. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, management or prevention of disease, or can affect the function and structure of the body. As can be seen from the definition, the Intermediates APIS is a key product of the previous process of manufacturing the API and has a different structure from the API

Finally, for example, amoxicillin capsules are called preparations, amoxicillin is called APIS, and 6-APA is called Veterinary Intermediates APIS.

Penicillin potassium for injection is called preparation, penicillin potassium is called Veterinary raw materials, and green potassium industrial salt is called intermediate
