Special fertilizer for rice seedling raising

Abstract

The invention discloses special fertilizer for rice seedling raising. The special fertilizer is prepared from the following raw materials in parts by weight: 60-70 parts of organic fermentation substances, 15-20 parts of fucoidin, 8-12 parts of amino acid chelate manganese, 4-6 parts of basic zinc sulfate, 12-18 parts of amino acid chelate iron, 12-16 parts of ammonium molybdate, 5-8 parts of selenomethionine, 0.5-1 part of humic acid, 3-6 parts of basic copper sulfate, 0.05-0.08 part of biochemical fulvic acid, 0.02-0.04 part of amino acid chelate calcium; 4-6 parts of lysine, 0.05-0.08 part of chitin, 4-6 parts of iodine yeast, 0.2-0.5 part of fungus polysaccharide, 0.5-1 part of S-abscisic acid, and 6-12 parts of a bacterium solution obtained by mixing azotobacter, cellulose decomposition bacteria and root nodule bacteria. The stress resistance of the special fertilizer adopting the formula to a plant is very high, so that the plant growth can be regulated, and the cold resistance, the disease resistance, the drought resistance and the water-logging resistance of the plant can be enhanced.

Description

technical field [0001] The invention relates to the field of rice seedling raising, in particular to a special fertilizer for rice seedling raising. Background technique [0002] Rice is an annual gramineous plant with a height of about 1.2 meters, long and flat leaves, and panicles composed of many spikelets. The planting process of rice is to first cultivate rice seedlings suitable for the seedling field stage on the seedling bed, and then sow the seedlings in the seedling field Medium; it has been proved by experiments that the range of PH value on the seedling bed is between 4.5-5.5 is the most suitable for seedling growth. In addition, it is necessary to add a variety of nutrients to meet the nutrition required by the seedlings and promote their growth. At present, adjust the seedlings The method of bed pH value and nutritional supplementation is to directly add sulfuric acid as a pH value regulator, and at the same time add nutrient composition modulators, but the form...

[0002] Rice is an annual gramineous plant with a height of about 1.2 meters, long and flat leaves, and panicles composed of many spikelets. The planting process of rice is to first cultivate rice seedlings suitable for the seedling field stage on the seedling bed, and then sow the seedlings in the seedling field Medium; it has been proved by experiments that the range of PH value on the seedling bed is between 4.5-5.5 is the most suitable for seedling growth. In addition, it is necessary to add a variety of nutrients to meet the nutrition required by the seedlings and promote their growth. At present, adjust the seedlings The method of bed pH value and nutritional supplementation is to directly add sulfuric acid as a pH value regulator, and at the same time add nutrient composition modulators, but the former is dangerous when used, and the nutrient elements in the commonly used nutrient composition modulators are unreasonable. There are many ineffective ingredients, so the dosage and the workload of farmers are very large, and the cost increases
