Embodiment 1
[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...
Embodiment 2
[0038] A mechanized high-efficiency sowing method for quinoa in coastal sandy saline-alkali land, comprising the following steps:
[0039] (1) Preparation: Select the coastal sandy saline-alkali land, use a tractor with a horsepower ≥ 100 and a turning plow to plow the soil before sowing, the plowing depth is 14-18cm, and then crush it with a disc harrow or a rotary tiller Rake up the soil without leaving any dead corners, and ensure that the accumulated water flows to the side of the drainage measures;
[0040] (2) Seed pretreatment: dry the seeds 2 days before sowing, soak the seeds with clear water for 2 hours 7 hours before sowing, and wait for the water content of the seeds to be 35%, remove and dry in the shade;
[0041] (3) Sowing: Sowing in mid-March, taking the seeds after step (2) dried in the shade, adopting ditching and sowing integrated, with a reamer, a trowel, and a 3.6m wide seeder for sowing, the seeding rate is 400g / mu; the seeding speed is 20g / min; the so...
Embodiment 3
[0044] A mechanized high-efficiency sowing method for quinoa in coastal sandy saline-alkali land, comprising the following steps:
[0045](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;
[0046] (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;
[0047] (3) Sowing: Sowing is carried out in mid-March. After mixing according to the ratio of urea-based compound fertilizer: quinoa seeds = 36:1, the sowing is integrated with ditching and troweling, with a width of 4m. Sowing by machine, the seeding rate is 500g / acre; the seeding speed is 30g / min; the sowing depth is 1-2cm, the plant spaci...
