Special fertilizer for rice seedling raising and preparation method thereof

Abstract

The invention discloses a special fertilizer for rice seedling raising and a preparation method thereof. The fertilizer is prepared from the following raw materials in parts by weight: 55-70 parts of human / animal manure, 14-18 parts of fucoidin, 1-2 parts of iron sulfite, 3-4 parts of ammonium molybdate, 2.5-4.0 parts of sodium hexametaphosphate, 2-3 parts of sodium bicarbonate, 1.1-1.3 parts of manganese sulfate, 0.9-1.0 part of sodium selenite, 9.5-11 parts of soil fertilizing agent, 2-3 parts of humic acid, 1-1.5 parts of sodium alkyl sulfonate, 1.2-1.5 parts of silicon nitride, 1-2 parts of xylitol, 3-5 parts of Fructus Forsythiae, 2-3 parts of rhubarb and 0.5-1.0 part of vitamin E. When being used for rice seedling raising, the special fertilizer for rice seedling raising can implement quick emergence of seedlings, strong seedlings, disease / insect resistance and developed root system, and is beneficial to quick seedling recovery after transplantation. The 25-day rice seedlings raised by the special fertilizer are strong and about 16cm high, and the survival percent is up to 95%; and thus, the special fertilizer is beneficial to high yield of rice culture.

Description

technical field [0001] The invention relates to a special fertilizer for raising rice seedlings and a preparation method thereof, belonging to the technical field of fertilizer manufacturing. 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 add a nutrient compon...

[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 add a nutrient component modulator at the same time, but the former is dangerous when used, and the nutrient element mix in the commonly used nutrient component modulator is unreasonable. There are many ineffective ingredients, so the dosage and the workload of farmers are very large, and the cost increases
