Embodiment 1

[0015] This example illustrates the effect of different amounts of nitrogen fertilizer on the content of propanol in cucumber fruit.

[0016] Cucumber variety tested: Dongnong 808, a cucumber variety with high propanol content. The experiment was sown on March 27, 2015, and planted in the plastic greenhouse of the experimental base of the Agricultural College of Heilongjiang Bayi Agricultural University on May 16. The soil type in the greenhouse is meadow chernozem, the basic agrochemical status of the 0-20cm plow layer soil is: soil alkaline nitrogen 184.7mg / kg, available phosphorus 21.4mg / kg, available potassium 237.7mg / kg, organic matter content 3.38% , pH 7.83, total salt 0.10%.

[0017] Basic fertilizer: (KH 2 PO 4 (P2O5: 52%, K 2 O: 35%), potassium sulfate (K 2 SO 4 (K 2 O: 54%)), urea (CO(NH 2 ) 2 , N: 46%).

[0018] per mu (667m 2 ) Apply 2500kg of organic fertilizer, 20kg of potassium dihydrogen phosphate, and 60kg of potassium sulfate. The amount of urea ...

Embodiment 2

[0026] This example illustrates the effect of different nitrogen form ratios on the content of tartronic acid in cucumber.

[0027] In result (1) the optimum nitrogen dosage is 80kg·667m -2 Urea (the amount of pure N is 36.8kg·667m -2 ) on the basis of amide nitrogen-urea as the control (CK), amide nitrogen (urea), NH 4+ -N(ammonium sulfate) and NO 3— N (calcium nitrate tetrahydrate) was used to set up three treatments with the ratio of pure nitrogen as 2:1:1 (T1), 1:2:1 (T2), and 1:1:2 (T3). Other fertilizer application methods and fields The management measures are the same as before. That is, 1 / 4 of the nitrogen fertilizer is used as the base fertilizer, and 3 / 10 of the remaining 3 / 4 of the nitrogen fertilizer is applied at the early fruiting stage of the cucumber, and the same amount is applied in 3 times; / 10, divided into 7 equal doses.

[0028] The urea consumption of the control, CK, is 80kg·667m -2 ; The amount of T1 nitrogen fertilizer is (urea 40kg + ammonium ...

Abstract

The invention relates to a nitrogen fertilizer application method for increasing the content of propanol diacid in cucumbers. The application amount of pure nitrogen in the nitrogen fertilizer is 36.8kg·667m-2, wherein 1 / 4 of the nitrogen fertilizer is used as the base fertilizer, and the remaining 3 / 4 of the nitrogen fertilizer is divided into 10 equal amounts Topdressing, specifically, includes amide nitrogen, ammonium nitrogen and nitrate nitrogen, of which 1 / 4 nitrogen fertilizer is used as base fertilizer, and the proportion of pure nitrogen in amide nitrogen, ammonium nitrogen and nitrate nitrogen is 1 in the initial stage of cucumber fruiting. : Apply 3 / 10 of the remaining 3 / 4 nitrogen fertilizer at a ratio of 2:1, and apply in equal amounts in 3 times; during the peak fruiting period of cucumbers, the ratio of pure nitrogen among amide nitrogen, ammonium nitrogen and nitrate nitrogen is 1 Apply 7 / 10 of the remaining 3 / 4 nitrogen fertilizer at a ratio of 1:2, and apply 7 times in equal amounts. The invention precisely applies nitrogen fertilizer to the cucumber, and provides the best nitrogen form and ratio, can greatly increase the content of propanol in the cucumber, and provides technical support for the rapid development of functional high-propanol cucumbers.

Description

technical field [0001] The invention belongs to the field of vegetable cultivation, and relates to a nitrogen fertilizer application method for increasing the content of propanol in cucumbers. Background technique [0002] Cucumber (Cucumis sativus L.), also known as pickled cucumbers and cucumbers, is native to the southern foot of the Himalayas. It has the characteristics of being warm, humid, and resistant to certain 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 redox function of the skin.
