Problems solved by technology

Therefore, there are still technical difficulties in using saline-alkali land with poor soil quality to plant rice. At present, before planting rice in saline-alkali land, it is usually necessary to improve the saline-alkali land and then carry out rice planting. However, the effect is not very satisfactory, and the yield is very low.

Embodiment 1

[0026] A method for planting rice in saline-alkali land in the Yellow River irrigated area, the method comprising the following steps:

[0027] S1. Seedling cultivation: mix peat, common soil, perlite, and vermiculite with a volume ratio of 3:3:2:2, add 230 g of carbendazim and 5.5 kg of compound fertilizer to the mixture per cubic meter, and stir the mixture evenly , to obtain the medium soil for raising seedlings, and use the medium soil to raise seedlings of rice;

[0028] S2. Sprinkle calcium sulfate powder in the saline-alkali paddy field with soft soil that has been plowed and stirred, plow and stir again, level the paddy field, and inject water until it is 10 cm above the leveled soil surface, and soak the field for 7 days;

[0029] S3. Drain the field water, wash it once with running water, apply soil improver, plow and level it again, inject water until it is 7 cm above the water surface, and insert rice seedlings;

[0030] S4, regularly applying topdressing fertiliz...

Abstract

The invention discloses a method for planting rice in a saline-alkali land of the Yellow River irrigation district. The method comprises the steps that (S1) seedling culture is carried out; (S2) calcium sulfate powder is scattered in a ploughed and stirred saline-alkali paddy field with loose and soft soil, ploughing and stirring are conducted again, the paddy field is leveled, water is injected till the water level is 5-10 cm higher than the flat soil surface, and field steeping is continued for 7-10 days; (S3) water accumulated on the field surface is discharged, washing with flowing water is conducted for one time, a soil conditioner is applied, ploughing and leveling are conducted again, water is injected till the water level is 3-7 cm higher than the water surface, and rice seedlings are inserted; and (S4) additional fertilizers are applied periodically to supplement rice nutrients till the rice gets mature. The method for planting the rice in the saline-alkali land of the Yellow River irrigation district disclosed by the invention has the advantages that operations are simple; the programming degree is high; promotion is easy; the planting cost is low; soil salinization can be improved; a soil pH value can be reduced; soil fertility can be increased; and the yield of the rice planted in the saline-alkali land can be increased by 20%-30%.

Description

technical field [0001] The invention relates to a method for planting rice in saline-alkali land in the Yellow River irrigation area. Background technique [0002] Saline-alkali soil is a general term for saline soil, alkaline soil and various salinized and alkalized soils. Saline soil refers to the soil in which the soluble salt content in the soil reaches a certain level, which can cause obvious harm to the growth and development of plants. Alkaline soil refers to the soil that contains a large amount of exchangeable ions in the soil, and the amount reaches the level that can harm the growth and development of plants and change the soil properties. In actual conditions, saline soil and alkaline soil often coexist in a mixed manner, collectively referred to as saline-alkali soil. [0003] The Yellow River irrigation area is the main grain base in my country, and the amount of coconut bran discharged from the Yellow River to irrigate farmland is nearly 9 billion m3 every y...
