specific Embodiment approach 1
[0024] Specific implementation mode one: the fast dry seedling raising method of rice in saline-alkali land in this implementation mode is specifically completed according to the following steps:
[0025] 1. The preparation concentration is 1.06g / cm 3 ~1.18g / cm 3 Put the seeds into the salt water to soak the seeds, wherein the soaking temperature is 36.5°C-38.5°C, the soaking time is 24h-36h, and then rinse the seeds 1-2 times, remove empty grains, impurities and germs, and get the treated seed;
[0026] 2. Select acidic peat soil and wind-blown sandy soil as the seedbed soil, level the seedbed, line it with film, cover the seedbed with 5cm-7cm thick seedbed soil, level and compact it, and then sow the treated seeds in step 1 , sow 0.5kg to 0.6kg per square meter, then cover with 1cm to 2cm of soil, and compact;
[0027] 3. Spray water into the seedbed soil after sowing in step 2 to make the seedbed soil completely moist, then cover with film, seal, and control the room tem...
