Embodiment 1

[0020] 1 Materials and methods

[0021] 1.1 Test time and place

[0022] The test was carried out in Fanjiatun paddy field, Dujia Town, Wuchang City, Heilongjiang Province from May to October 2017. The soil type is sandy loam, and the soil basic fertility: organic matter 39.87g kg -1 , total nitrogen 1.85g·kg -1 , available nitrogen 15.00mg·kg -1 , available phosphorus 24.0 0mg·kg -1 , available potassium, 97.00mg·kg -1 , the pH value is 6.32.

[0023] 1.2 Test varieties

[0024] "Daohuaxiang No. 2" is a traditional local aromatic rice variety in Wuchang City.

[0025] 1.3 Experimental Design (Table 1)

[0026] The experiment of the interaction between nitrogen and sulfur on the yield of fragrant rice was set up with 3 nitrogen levels, namely 0kg / ha, 90kg / ha and 180kg / ha equivalent to pure nitrogen; 3 sulfur levels, namely 0kg / ha and 45kg / ha equivalent to pure sulfur ha and 90kg / ha, a total of 9 treatments. Nitrogen fertilizer is provided by urea (46.67% nitrogen cont...

Abstract

The invention discloses a nitrogen-reduced ecological fertilizer capable of increasing the yield of Wuchang fragrant rice. The weight ratio of nitrogen to sulfur in the ecological fertilizer is (90-180):45. High yield, the yield increasing benefit of a nitrogen element and the highest utilization ratio of the nitrogen element are realized by the matched application of the nitrogen element and a sulfur element, so that the nitrogen-reduced ecological fertilizer capable of increasing the yield of the Wuchang fragrant rice and a fertilizer application method are matched.

Description

technical field [0001] The invention relates to a nitrogen-reducing ecological fertilizer and a fertilization method for increasing the yield of Wuchang fragrant rice. Background technique [0002] Daohuaxiang No. 2, a traditional local rice variety in Wuchang City, has the characteristics of strong aroma, disease resistance, etc., and has excellent nutritional quality, rich in various amino acids, proteins, trace elements and other nutrients. After cooking, the surface is oily and shiny, the taste is light and slightly sweet, soft and sticky, fragrant and refreshing, and is favored by consumers. Its climatic conditions, geographical conditions and ecological advantages are unique, and the temperature difference between day and night is large, which is conducive to the accumulation of rice aroma. There are 600,000 rice farmers and 120,000ha of planted area growing year by year in the region. The rice industry plays an important role in the economy of Wuchang City. However...
