Embodiment 1

[0016] In this embodiment, early rice is taken as an example.

[0017] (1) Fertilization during land preparation: when preparing the land before rice transplanting, apply organic fertilizer at one time, apply 2200 kg of fresh green manure per mu, apply calcium magnesium phosphate fertilizer 38 kg, ammonium bicarbonate 16 kg, and potassium sulfate 10 k per mu during harrowing;

[0018] (2) Top dressing:

[0019] The first top dressing was applied about 7 days after transplanting, 7.5kg of urea, 7.5kg of potassium sulfate or 5-6kg of potassium chloride were applied per mu;

[0020] The second topdressing was applied about 15 days after transplanting, and 8-kg of urea and 10.5 kg of potassium sulfate were applied per mu;

[0021] (3) Ear fertilizer: Spray foliar fertilizer at the booting stage and mature stage, and spray 6-7kg of potassium dihydrogen phosphate per mu.

[0022] During the whole fertilization process, the ratio of nitrogen, phosphorus and potassium is 1:0.4:1.3. ...

Embodiment 2

[0025] In this embodiment, take late rice as an example.

[0026] (1) Fertilization during land preparation: when preparing the land before rice transplanting, apply organic fertilizer at one time, 1000-1500 kg of manure per mu, apply 40 kg of calcium magnesium phosphate fertilizer, 20 kg of ammonium bicarbonate, and 6 kg of potassium chloride per mu during harrowing;

[0027] (2) Top dressing:

[0028] The first top dressing was applied about 7 days after transplanting, 8.5kg of urea and 5.5kg of potassium chloride were applied per mu;

[0029] The second top dressing was applied about 15 days after transplanting, with urea 10kg and potassium chloride 9.5kg per mu;

[0030] (3) Ear fertilizer: Spray foliar fertilizer at the booting stage and mature stage, and spray 6-7kg of potassium dihydrogen phosphate per mu.

[0031] During the whole fertilization process, the ratio of nitrogen, phosphorus and potassium is 1:0.4:1.3.

[0032] 30 days after the late rice is transplanted...

Abstract

The invention discloses a fertilizing method for paddy rice. The fertilizing method has the advantages that staged fertilizing is adopted, organic fertilizer is combined with inorganic fertilizer, theapplication quantity of the organic fertilizer is increased while the application quantity of inorganic fertilizer is reduced, and accordingly soil organic matter is increased, and the destructive effect of inorganic salt on soil is reduced; the whole fertilizing method is simple, effective and capable of well increasing paddy rice yield.

Description

technical field [0001] The invention relates to the field of rice fertilization. Background technique [0002] Rice is one of the main food crops in the world, and about half of the world's population depends on rice as a staple food. China's rice cultivation area accounts for about 1 / 4 of the world's total rice cultivation area, while its output is about 37% of the world's total rice production and 45% of the country's total grain production. And the main problem existing in rice fertilization at present is that fertilization is unscientific, and long-term application of chemical fertilizers leads to rice floor knots, poor rice growth, low yield, poor quality, and low economic benefits. Contents of the invention [0003] The object of the present invention is to provide a method for fertilizing rice in view of the above technical problems. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A method for fertili...
