1. The application of zinc fertilizer can reduce the nitrate and nitrite content in fresh vegetables. In conjunction with the spraying of strong stem, it can make the plant roots robust, green leaves, and natural taste. The production of 1000 kg of celery requires 2.0 kg of pure nitrogen, 0.93 kg of phosphorus pentoxide and 3.9 kg of potassium oxide.
2. Before planting, apply 4000-5000 kg of organic fertilizer per acre, 150 kg of biological organic compound fertilizer, 40 kg of urea, 25-35 kg of superphosphate, 40 kg of potassium sulfate, and 1-1.5 kg of zinc sulfate.
3. The plants enter a vigorous growth period and carry out the first topdressing, applying 3 kg of pure nitrogen per mu, and 5 to 6 kg of potassium oxide. After two months into the second topdressing, pure nitrogen 2 ~ 2.5 kg per acre, potassium oxide 4 ~ 5 kg. Strong growth period can be sprayed 0.2~0.5% borax.
4, can be applied per acre 3000-4000 kg of organic fertilizer or dried chicken manure 1300 kg, plus superphosphate 40-50 kg, 7-10 kg of potassium sulfate, 30-40 kg of ammonium sulfate or compound fertilizer 75 kg as the base fertilizer The base fertilizer and the soil were mixed well, and then the car was used. The car was 1.5 meters wide, 0.3 meters wide, and 0.3 meters deep. Six plants per hole were planted. The plant spacing was 15 centimeters and 1200 bushes were planted per acre.
5, in the 7 days before planting Shizu, 7-10 days after planting, can be applied once about 10% of clearing water or urea 5 kg per acre applied to promote seedlings to form a good root system, restore growth. In the next 40 days, urea 10 kg or 30-40% of manure water can be applied 1-2 times to promote the growth of the heart.
Functional oligosaccharides refer to oligosaccharides that are difficult or impossible to be digested and absorbed by the human body and have special physiological effects on the human body. Its sweetness is generally only 30-50% of that of sucrose, and it has physiological functions such as low-calorie, anti-caries, prevention and treatment of diabetes, and improvement of intestinal colony structure. Due to the special physiological functions of functional oligosaccharides, it becomes a nutrient and health care product. A new generation of food-effect raw materials that integrate diet and therapy. It is a new functional sugar source that replaces sucrose and has a wide range of uses and application prospects. Common functional oligosaccharides include: xylo-oligosaccharides, fructooligosaccharides, galacto-oligosaccharides, isomaltose, raffinose and so on.
