Embodiment 1
[0009] The soil in the wheat experimental field of Henan Normal University is sandy loam, and the soil in the 0-30 cm soil layer contains 10.7 g / kg of organic matter, 0.46 g / kg of total nitrogen, 60.1 mg / kg of alkaline nitrogen, 31.1 mg / kg of available phosphorus, and 31.1 mg / kg of available phosphorus, respectively. Potassium 92.1 mg / kg. Three winter wheat cultivars Yumai 49-198, Xinmai-208 and Aikang-58 were used as test materials, sown on October 18, 2011, and on October 20, 2012 (variety Aikang-58 was tested in Hongqi, Xinxiang City Except for the wheat fields in Guandi Village, Hongmen Town, District), the basic seedlings are 150,000. The area of the plot is 2.9 m×6 m (17.4 m 2 ), arranged in random blocks and repeated 3 times. Apply dry chicken manure 1.7 t / mu, Stanley (San’an) compound fertilizer 50 kg / mu, N-P 2 o 5 -K 2 O=18:18:18, total nutrient ≥54%, N-P 2 o 5 -K 2 The amount of O per mu was 9 kg, and Stanley (San'an) compound fertilizer was topdressed at 2...

[0011] The soil in the wheat field in Guandi Village, Hongmen Town, Hongqi District, Xinxiang City is clay loam, and the soil organic matter in the 0-30 cm soil layer contains 7.3 g / kg total nitrogen, 0.32 g / kg total nitrogen, 18.7 mg / kg Phosphorus 26.3 mg / kg, available potassium 83.4 mg / kg. The winter wheat variety Aikang-58 was used as the experimental material, sown on October 20, 2012, with 150,000 basic seedlings. The area of the plot is 2.9 m×6 m (17.4 m 2 ), arranged in random blocks and repeated 3 times. Refer to the fertilization method adopted in large areas in the local area, apply monoammonium phosphate 50 kg / mu before the cultivated land in each plot, N-P 2 o 5 -K 2 O=11:44:0, total nutrient ≥55%, N-P 2 o 5 -K 2 The amount of O per mu is 5.5-22 -0 kg, produced by Jiyuan Toyota Fertilizer Co., Ltd.; topdressing urea 25 kg / mu in the jointing stage with watering, total nitrogen ≥ 46.4%, and the amount of N per mu is 11.6 kg, Henan Produced by Xinlianxin Fer...
Embodiment 3
[0013] Treatment method: Exogenous NO donor is sodium nitroprusside {sodium nitroferricyanide (dihydrate), Na 2 [Fe(CN) 4 NO]·2H 2 O, molecular weight 297.95; Sodium nitroprusside dihydrate, SNP}, purchased from Sinopharm Chemical Reagent Co., Ltd., the original drug content ≥ 99.0% (analytical pure). Concentration unit: weight Weigh 0.0596 g of SNP with an analytical balance, dissolve it in 2 L of distilled water, and prepare a 100 μmol / L (2.98×10-2 g / L) SNP solution, 5 days after wheat flowering, that is, the initial stage of grain formation Spray the whole plant, and the spraying amount is equivalent to 100 mL / m 2 , 66.7 L sodium nitroprusside solution / mu (equivalent to 19.8766 g of the original drug per mu), carried out at 18:00-19:00 in the evening. Use 5.0 mL / L Tween-80 as an adhesion promoter to facilitate its adhesion on the leaves. The experimental field without any treatment was used as the control.
