Mechanized efficient seeding method suitable for chenopodium quinoa in coastal sandy saline-alkali soil

Abstract

The invention provides a mechanized efficient seeding method suitable for chenopodium quinoa in coastal sandy saline-alkali soil. A large-scale seeding machine integrating ditching and seeding is utilized, parameters of the seeding machine are controlled, such that mechanical seeding of chenopodium quinoa in coastal sandy saline-alkali soil is realized, and the seeding efficiency of chenopodium quinoa is improved while a seedling emergence rate is ensured. Aiming at characteristics of high sand content and high underground water level of coastal sandy saline-alkali soil, the seeding machine integrating ditching and seeding is adopted, an advancing speed and a seeding speed of the seeding machine are controlled, such that the seeding efficiency is improved, the seeding cost is reduced, resource waste is reduced, coastal saline-alkali soil resources are fully utilized, and a foundation is laid for characteristic agricultural development in coastal regions.

Description

technical field

[0001] The invention relates to the field of mechanized sowing, in particular to a mechanized high-efficiency sowing method for quinoa in coastal sandy saline-alkali land. Background technique

[0002] Quinoa is a kind of complete nutrition cereal crop, which is rich in vitamins, polyphenols, flavonoids, saponins and phytosterols. Foods with low fructose and low glucose can exert beneficial effects in the process of glucose and lipid metabolism. Quinoa is native to Colombia, Ecuador, Peru and other middle and high-altitude mountainous areas in the Andes of South America. It has certain drought tolerance, cold resistance, and salt tolerance. It grows from sea level to plateaus at an altitude of about 4,500 meters. Plateau or mountainous areas with an altitude of 3000-4000 meters above sea level. Quinoa's outstanding salt-tolerant characteristics and excellent nutritional quality enable it to survive in saline-alkali land. Therefore, planting quinoa in coasta...

[0032] A mechanized high-efficiency sowing method for quinoa in coastal sandy saline-alkali land, comprising the following steps:

[0033] (1) Preparation: Select coastal sandy saline-alkali land, and use a tractor with a horsepower ≥ 100 with a turning plow to plow the soil before sowing. Rake up the soil without leaving any dead corners, and ensure that the accumulated water flows to the side of the drainage measures;

[0034] (2) Seed pretreatment: dry the seeds 3 days before sowing, soak the seeds with clear water for 3 hours 8 hours before sowing, and wait for the moisture content of the seeds to be 36%, remove and dry in the shade;

[0035] (3) Sowing: Sowing was carried out in mid-March. After mixing according to the ratio of sulfur-based compound fertilizer: carbon-based fertilizer: quinoa seeds = 36:14:1, it was integrated with ditching and sowing, with reamers and trowels. The seeder with a width of 4m is used for sowing, the seeding rate is 500g / mu; the seeding spe...
