Embodiment 1
[0016] A special seedling-raising substrate for machine-transplanted medium and large seedlings of hybrid indica rice, including main materials and auxiliary materials. The main materials include 90% of decomposed fungus residue and 10% of dry fine soil;
[0017] Auxiliary materials include urea, superphosphate, uniconazole, carbendazim and dexazone, and the weight ratio of the main material to urea is 2000:3, and the weight ratio of the main material to superphosphate is 400:3. The weight ratio to uniconazole is 4×10 6 :3, the main ingredient and carbendazim weight ratio are 4000:1, and the main ingredient and dexon weight ratio are 4000:1.
[0018] A method for preparing a special seedling-raising substrate for machine-transplanting medium and large seedlings of hybrid indica rice, the steps comprising:
[0019] (1) Bacteria residue pretreatment: remove hard impurities, control the moisture content of the bacteria residue to be controlled at 35-45%;
[0020] (2) Fermentati...
Embodiment 2
[0024] A rice substrate seedling cultivation method, comprising:
[0025] (1) The matrix that the present invention cooperates has invented the medium-large seedling seedling wet-oxygen cultivation method, and the medium-large seedling wet-oxygen cultivation method can effectively improve the quality of planting (as shown in Table 2), and can increase the elasticity of the seedling age (Table 1).
[0026] Substrate seedling raising method steps are as follows:
[0027] Step 1: Choose a fertile and flat seedling field to make a moisturizing seedling box with a width of 1.1-1.4 meters, and ditch around it to facilitate irrigation and drainage;
[0028] Step 2: Start soaking the seeds one day before sowing, soak the seeds for more than 12 hours, and then dry them until the seeds are loose and not sticky;
[0029] Step 3: Use the fully automatic rice seedling raising and sowing line to complete the steps of substrate laying, sowing and covering;
[0030] Step 4: Place the sown s...
