Problems solved by technology

[0002] The area of ​​soda saline-alkali land in the west of Songnen Plain in Northeast China is 3.8 million hm 2 , because the soil contains a lot of Na + , CO 3 2- and HCO 3 - , high soil pH and salinity, low organic matter content, nutrient deficiency, low fertility, poor air permeability and water permeability, making it difficult to improve and utilize
Practice has proved that rice planting is one of the effective agronomic measures to improve the use of soda saline-alkali land, but limited by the traditional planting system, the high yield and stable yield of rice are poor
[0003] The traditional rice planting method is convenient to rake the land, the field surface is clean, and only a short rice stubble is left when harvesting. Water harrowing requires high-horsepower agricultural machinery and more fuel consumption; with water harrowing, the mashing machine has a large operating depth, and it is easy to re-stir the buried rice stubble to the field surface, affecting transplanting and rice growth; at the same time Due to the dry and windy spring and the large amount of evaporation, it is easy to cause soil moisture loss and salt surface accumulation to accelerate and increase, thus increasing the water consumption for soaking soda
In addition, the physical and chemical properties of the soil in soda saline-alkali land are poor, characterized by high bulk density, low porosity, weak water permeability, and slow slurry sedimentation after soaking the field, so the traditional rice planting method is not suitable for soda saline-alkali land
In terms of nitrogen fertilizer application, because the saline-alkali land is cold and cool in the early stage, in order to make rice grow early and quickly, the traditional planting basal fertilizer and tiller fertilizer are applied in a large amount, and the amount of ear fertilizer and grain fertilizer is small (generally applied in a ratio of 4:3:2:1). Cause large-scale lodging in the later stage; in the application of phosphorus fertilizer, because the absorption and utilization of phosphorus are hindered by saline-alkali land, rice in saline-alkali land has a common phenomenon of phosphorus deficiency

Embodiment 1

[0042] In the mild saline-alkali soil paddy field of Hongguang Farm, Qianguo County, after the autumn harvest, the height of the stubble is 20-30 cm, and the stubble is turned over and buried in autumn with a depth of 20 cm. In spring, when the soil is thawed at about 15cm, apply the base fertilizer and then dry and level it, suppress and break the fat blocks, and do not harrow the land with water. Soak the field and wash the field 1-2 times, and transplant the seedlings after 1-2 days of precipitation. Apply 160kg of pure nitrogen per hectare (conventional 200kg, reduce nitrogen by 20%), 80kg of pure phosphorus (65kg conventionally, increase phosphorus by 23%), 90kg of pure potassium, and 25kg of zinc sulfate.

[0043] Base fertilizer: Apply all organic fertilizers to the paddy fields before plowing. On this basis, apply 40% of nitrogen fertilizer, 70% of potassium fertilizer, phosphorus fertilizer and zinc fertilizer as base fertilizer.

Embodiment 2

[0051] In the paddy fields with moderate saline-alkali soil in Gashigen Township, Zhenlai County, after the autumn harvest, the height of the stubble is 20-30 cm, and the stubble is turned over and buried in autumn with a depth of 15 cm. In spring, when the soil is thawed at about 15cm, apply the base fertilizer and then dry and level it, suppress and break the fat blocks, and do not harrow the land with water. Soak the field and wash the field 2-3 times, and transplant the seedlings after 1-2 days of precipitation. Apply 150kg of pure nitrogen per hectare (conventional 200kg, reduce nitrogen by 25%), 83kg of pure phosphorus (65kg conventionally, increase phosphorus by 27%), 100kg of pure potassium, and 25kg of zinc sulfate.

[0052] Base fertilizer: Apply all organic fertilizers to the paddy fields before plowing. On this basis, apply 40% of nitrogen fertilizer, 70% of potassium fertilizer, phosphorus fertilizer and zinc fertilizer as base fertilizer.

Abstract

The invention provides a comprehensive planting method of recarburization, oxygenation and resistance-increasing of paddy rice in soda saline-alkaline land. The comprehensive planting method achieves aims of saving water resources, optimizing a soil structure and improving fragile ecological environment by stubble, returning to filed and recarburization of straw, drought leveling, water-harrowing-removing, and oxygenation, reducing nitrogenous fertilizer, increasing phosphatic fertilizer and increasing resistance. The comprehensive planting method promotes high yield, dependable crop and sustainable development of paddy rice of a salt-alkali adverse situation and improves social benefits, economic benefits and ecological benefits.

Description

technical field [0001] The invention provides a carbon-increasing, oxygen-increasing, and resistance-increasing comprehensive planting method for rice in soda saline-alkali land, which is used for comprehensive production in low- and medium-yield paddy fields, and belongs to the agricultural crop production and planting technology. Background technique [0002] The area of ​​soda saline-alkali land in the west of Songnen Plain in Northeast China is 3.8 million hm 2 , because the soil contains a lot of Na + , CO 3 2- and HCO 3 - , high soil pH and salinity, low organic matter content, nutrient deficiency, low fertility, poor air permeability and water permeability, making it difficult to improve and utilize. Practice has proved that rice planting is one of the effective agronomic measures to improve and utilize soda saline-alkali land, but limited by the traditional planting system, the high yield and stable yield of rice are poor. [0003] The traditional rice planting...
