Embodiment 1
[0016] A method for preparing a rice disease-resistant seedling-raising substrate, the specific steps are as follows:
[0017] (1) taking field soil and rice straw as main raw materials, crushing the field soil, and continuously drying the field soil at a temperature of 85-95° C. for 10-14 minutes to sterilize the field soil and harden the field soil;
[0018] (2) Collect the harvested rice stalks, then cut them into 2-3 cm long sections, spray water on the cut stalks, and spray 1.5-1.8kg of water per 10kg of rice stalks to moisten the stalks and increase the moisture content;
[0019] (3) Send the rice straw section in the wet state into the tumbler for tumble processing, vacuumize once every 9-10 minutes during tumble, tumble for 15 minutes after vacuuming each time, and then evacuate, so Cycle 5 times; enable the straw to achieve the effect of breathing massage in the process of rolling and kneading, soften the straw and improve the utilization rate of internal active ingr...
