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...

Abstract

The invention discloses a seedling-strengthening agent special for super rice and a using method thereof. The seedling-strengthening agent special for the super rice consists of the following components in part by weight: 50 parts of ammonium sulfate, 10 parts of superphosphate, 19.6 parts of potassium chloride, 20 parts of biological organic fertilizer, 0.2 part of paclobutrazol and 0.2 part of carbendazim. The seedling-strengthening agent can obviously improve the leaf emergence rate of seedlings, reduce the plant height, increase the stem base width, the biomass and the chlorophyll contentof the seedlings, obviously improve the protein and proline content of the seedlings, and enhance the activity of phenylalanine ammonia-lyase so as to improve the stress tolerance of the seedlings and fulfill the aim of culturing strong seedlings.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a special seedling strengthening agent for super rice and its application method. Background technique [0002] Seedling raising is an important link in the rice planting process, and the quality of the seedlings directly affects the rice yield. The quality of seedlings is not only closely related to the nutritional status of the bed soil, but also affected by the regulation of fertilizer and water in the process of raising seedlings. Seedling strengthening agent is a physical and chemical technology for rice seedling raising. It integrates bed soil acid adjustment, sterilization, seedling nutrition and chemical regulation. It not only has the advantages of simple operation, labor saving and cost saving, but also makes it easier to cultivate strong seedlings. However, the existing seedling-strengthening agents have a single function and a narrow range of application, and a...
