Embodiment 1
[0016] Mix the following components according to the ratio: 50% ammonium sulfate, 10% superphosphate, 19.6% potassium chloride, 20% bio-organic fertilizer, 0.2% paclobutrazol and 0.2% carbendazim. It is packaged in a small package of 1kg per bag. When in use, place the plastic tray on the seedling bed, pour a small amount of water into the working ditch of the seedling bed before sowing, and add 20 grams of "Super Rice Seedling Strengthening Agent" per plastic tray "Amount of use, use an iron rake to drag back and forth to form mud, use a spoon to pour the mud into the plastic plate, scrape the mud and then sow. After sowing, lightly press the seeds to prevent root stringing, cover early rice with plastic film and eliminate waterlogging in the field, etc. After sowing late rice, straw can be used to prevent rainwater erosion to ensure the cultivation of strong seedlings. Each pack of super rice seedling strengthening agent is 1 kg, which can cultivate 1 mu of rice seedlings fo...
Embodiment 2
[0017] Embodiment 2 comparative experiment
[0018] The experiment was carried out on March 5, 2006 at the Agronomy Experimental Field of South China Agricultural University. Two factors were set up in the experiment: seedling strengthening agent treatment and seedling raising method. Seedling strengthening agent is set without applying seedling strengthening agent (contrast, conventional seedling raising) and applying seedling strengthening agent (the dosage of seedling strengthening agent is 30g / m 2 ) two treatments; the seedling raising method sets two treatments of dry seedling raising and wet seedling raising. Three repetitions were set for each treatment, randomized block design, and the area of the seedling plot was 10 m 2 . Sampling according to the relevant literature at the 3 leaf stage of the seedlings, measure the plant height, stem base width, biomass and seedling rate of the seedlings; measure the chlorophyll, proline (Pro and soluble protein content of th...
