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 nitrogenous fertilizer application method for improving content of tartronic acid in cucumbers. According to the method, the application amount of pure nitrogen in nitrogenous fertilizer is 36.8 kg.667 m<-2>, wherein one fourth of nitrogenous fertilizer is used as base fertilizer, and the rest of 3 / 4 of nitrogenous fertilizer is used for equivalent topdressing by 10 times respectively, specifically, the nitrogenous fertilizer comprises amidonitrogen, ammonium nitrogen and nitrate nitrogen, one fourth of nitrogenous fertilizer is used as base fertilizer, at the initial fruiting stage of cucumbers, 3 / 10 of the rest of 3 / 4 of nitrogenous fertilizer is applied equivalently for 3 times respectively as per the fact that the ratio of contents of pure nitrogen in amidonitrogen, ammonium nitrogen and nitrate nitrogen is 1:2:1; at the fast fruiting stage of cucumbers, the rest 7 / 10 of the rest of 3 / 4 of nitrogenous fertilizer is applied equivalently for 7 times respectively as per the fact that the ratio of contents of pure nitrogen in amidonitrogen, ammonium nitrogen and nitrate nitrogen is 1:1:2. According to the invention, nitrogenous fertilizer application is precise, and the optimal nitrogen forms and matching are provided, so that content of tartronic acid in cucumbers is greatly increased, and technical support is provided for rapid development of functional high-tartronic acid 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 (Cucumissativus L.), 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 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. ...
