[0027] Embodiment: A preparation and seedling raising method of straw marsh soil for rice machine transplanting, comprising the following steps:
[0028] 1. Substrate preparation After the rape, rice, corn, cotton, soybean and other crop straws are pulverized with a conventional straw pulverizer, 1200 kg of biogas slurry and / or biogas residue and 2000 kg of loam are added to 1000 kg of crop straw to fully Mix evenly, dry and wet according to the principle of kneading into a ball by hand, and then dispersing on the ground, then pile it up, cover it with a woven bag or plastic cloth to prevent rain, do not cover tightly, prevent airtightness, and it is appropriate for the straw to turn brown, i.e. Get straw.
[0029] 2. Substrate loading and trays Load the prepared substrates into the rice mechanical seeding line to load the seedling trays, adjust the thickness of each tray to 25mm, and pour water.
[0030] 3. Sowing and raising seedlings The sowing rate of conventional see...
