Embodiment 1

[0021] Example 1: The experiment was arranged in a salinity-alkali improvement demonstration area in a town in Shuozhou City, Shanxi Province. It is located in the north of Shanxi Province, with an average annual precipitation of about 362.4 millimeters and evaporation of about 1940 millimeters. The average temperature over the years is 7.6°C, and the frost-free period is 120-138 days. It belongs to the inland arid saline-alkali area, the soil type is mainly soda-type alkaline soil, the groundwater generally contains soda, and 70% of the saline-alkali soil contains soda. The total salt content of the plow layer (0-20cm) is generally 3-5g / kg, the pH value is generally 8.7-9.2, the EC value is about 1-1.5, and the alkalization degree is generally 10-15%, which belongs to moderate soda saline-alkali land.

Embodiment 2

[0034] Example 2: The demonstration is arranged in a village in a certain county of Datong City, which belongs to the continental north temperate zone dry monsoon climate, with four distinct seasons, a frost-free period of 90-128 days, an average annual sunshine hours of 2,827 hours, an annual average temperature of 6.4°C, and an average altitude of 994 meters. According to the Shanxi soil annals of the second national soil census, this area belongs to the inland arid saline-alkali area, the total salt content of the soil plow layer (0-20cm) is generally 5-7g / kg, and the soil pH is 9.2-9.5 , the EC value is about 1.5-2, the alkalization degree (ESP) is about 15-30%, the content of substitutable sodium ions in the soil is high, the soil colloid is dispersed, the aggregate structure is poor, the soil swells and becomes muddy when it is wet, and shrinks when it is dry. It is hard and highly alkaline, and it is difficult for crops to grow. It is a severe soda saline-alkali land.

Embodiment 3

[0047] Embodiment 3: A planting method of quinoa in inland soda saline-alkali soil, wherein: the desalination water-retaining agent is made by mixing the following raw materials: 70g calcium-based bentonite, 15g sulfur, 3.5g ferrous sulfate, 15g humic acid, 10g sticky Mixture, 10g of water. The inland soda saline land is extremely severe soda saline land, the total salt content of the soil plow layer (0-20cm) is not less than 7g / kg, the soil pH is not less than 9.5, the EC value is not less than 2, and the alkalization degree (ESP) is not less than 30%. In step (2), the amount of desulfurization gypsum is 1.5 tons / mu, and the farm organic fertilizer is cow dung, and the amount is 2m 3 / mu. All the other planting methods are with the method described in Example 2.

[0048] Compared with the conventional planting by local farmers (do not apply desulfurization gypsum, but store water and pressurize salt, do not coat the seeds before sowing, and do not spray biological agents at...

Abstract

The invention belongs to the technical field of crop planting and cultivation in specific soil, and provides a planting method for quinoa in an inland soda saline-alkaline land to solve problems likelow seedling emergence rate, susceptibility to saline-alkaline stress in a seedling stage and field waterlogging for quinoa planting in a soda saline-alkaline land. The planting method comprises the following steps: with a desalting agent as a core, and by cooperation with agricultural process and chemical measures, constructing a drainage ditch; carrying out soil preparation in autumn; carrying out soil treatment before sowing in spring, and carrying out deep plowing and shallow rotary tillage; soaking seeds with the desalting agent before sowing; and spraying a biological agent in the seedling stage so as to protect seedlings. According to the invention, chemical improvement measures are adopted to neutralize salt and alkali, and irrigation is performed to wash salt, so the damage degreeof salt and alkali to the quinoa is reduced; fine tillage is performed for soil before sowing, and the depth of sowing is controlled, so germination of small-grained quinoa seeds is promoted; biological improvement measures are adopted for soaking and coating of quinoa seeds before sowing, and the biological agent is sprayed in the seedling stage, so the saline-alkali resistance of seeds and seedlings is improved, and the purpose of improving the seedling emergence rate and the seedling protection rate is achieved; and simple operation and significant effects are achieved. The planting methodprovided by the invention has a certain promotion action to planting popularization of the quinoa in the soda saline-alkali land.

Description

technical field [0001] The invention belongs to the technical field of crop planting and cultivation in specific soil, and in particular relates to a method for planting quinoa in inland soda saline-alkali land. Background technique [0002] Quinoa( Chenopodium quinoa willd ) is native to the Andes in South America. It is the main traditional food of the Inca indigenous people. It has a planting history of more than 5,000 to 7,000 years. Because of its unique rich and comprehensive nutritional value, it has nurtured the Inca nation. The ancient Inca called it " The mother of food". The Food and Agriculture Organization of the United Nations believes that quinoa is the only food that a single plant can meet the basic nutritional needs of the human body, and officially recommends quinoa as the most perfect and complete nutritional food for humans. The United Nations declared 2013 as the International Year of Quinoa to promote human nutrition, health and food security, and to...
