Abstract

The invention relates to a nitrogenous fertilizer application method, in particular to a nitrogenous fertilizer application method capable of increasing the content of tartronic acid in cucumbers, and belongs to the field of agricultural planting. The method aims at solving the problem that the content of tartronic acid in existing cucumber fruits is low. According to the method, the application amount of pure nitrogen in nitrogenous fertilizer is 10804.50 mg / plant; the fertilizer is applied in batches according to the development stages of cucumbers, wherein before planting, the fertilizer is applied in 2 times in an equal-amount topdressing mode at the amount of 220.50 mg / plant, and after planting, the fertilizer is applied in 6 times in an equal-amount topdressing mode at the amount of 10584 mg / plant.

Description

technical field [0001] The invention relates to a method for using nitrogen fertilizer, in particular to a method for using nitrogen fertilizer for increasing the content of propanol in cucumbers, and belongs to the field of agricultural planting. Background technique [0002] Cucumber, also known as pickled cucumbers and green cucumbers, is native to the southern foot of the Himalayas. It has the characteristics of being warm, humid, and resistant to low light. Cucumber is rich in nutrients, including protein, fat, carbohydrates, ash, calcium, phosphorus, iron, carotene, thiamine, riboflavin, vitamins and so on. In addition, it also contains glucose, fructose, caffeic acid, chlorogenic acid, various free amino acids and volatile oil, cucurbitacin, cucumber enzyme, etc. Among them, cucumber enzyme is a biological enzyme with strong biological activity, which can effectively promote the body's metabolism, expand skin capillaries, promote blood circulation, and enhance the ox...
