Embodiment 1

[0018] A seedling raising substrate, the volume percentage of ingredients is: 20% of peat, 40% of peat, 25% of vermiculite, and 15% of perlite. The above group materials are mixed as the base, and 1.5kg of diammonium phosphate, 0.2kg of microbial organic fertilizer, and 0.15kg of trace element additives are added per 1 cubic meter. The production method is as follows: put peat and peat into a sealed container and pass through 250°C water vapor for 30 minutes of high-temperature sterilization; , diammonium phosphate, microbial organic fertilizer, and trace element additives are put into the blender and twisted; the evenly twisted matrix enters the sieving process, the matrix above the sieve enters the pulverizer for crushing, and the crushed matrix returns to the twister; The sieved matrix enters the quantitative container for measurement; finally, it is packaged, that is, it is packed and sealed according to the quantitative quantity, and the finished matrix is ​​produced.

Embodiment 2

[0022] A seedling raising substrate, the volume percentage of ingredients is: 18% of peat moss, 50% of peat, 20% of vermiculite and 12% of perlite. The above group materials are mixed as the base, and 1.6 kg of diammonium phosphate, 0.25 kg of microbial organic fertilizer, and 0.18 kg of trace element additives are added per 1 cubic meter. The production method is as follows: put peat and peat into a sealed container and pass through 300°C steam for 45 minutes for high-temperature sterilization. The following production procedures are the same as those described in Example 1.

[0023] The trace element additives are: copper sulfate 16%, ferrous sulfate 6%, fulvic acid 0.15%, potassium sulfate 37.85%, zinc sulfate 11%, borax 29%. Based on the mixing of the above components, 3.5 mg of sodium 5-nitroguaiacol was added per kilogram. The borax in the additive can be replaced by boric acid, or the mixture of borax and boric acid can be used, as long as the required total amount of ...

Embodiment 3

[0025] A seedling-raising substrate, the volume percentage of ingredients is: 16% of peat, 44% of peat, 27% of vermiculite, and 13% of perlite. The above group materials are mixed as the base, and 1.7kg of diammonium phosphate, 0.3kg of microbial organic fertilizer, and 0.2kg of trace element additives are added per 1 cubic meter. The production method is as follows: put peat and peat into a sealed container and pass through 350°C water vapor for 60 minutes of high-temperature sterilization. The following production procedures are the same as those described in Example 1.

[0026] The trace element additives are: copper sulfate 17%, ferrous sulfate 7%, fulvic acid 0.18%, potassium sulfate 35%, zinc sulfate 12%, borax 28.82%. Based on the mixing of the above components, 3.8 mg of sodium 5-nitroguaiacol was added per kilogram. The borax in the additive can be replaced by boric acid, or the mixture of borax and boric acid can be used, as long as the required total amount of bora...

Abstract

The invention discloses a nursery substrate and a method for manufacturing the same. The main compositions in percentage by volume of the nursery substrate are 0 to 20 percent of grass carbon, 40 to 60 percent of peat, 20 to 35 percent of vermiculite and 10 to 15 percent of perlite; the compositions are mixed and taken as a base number; moreover, 1.5 to 2.0kilograms of diammonium phosphate, 0.2 to 0.5kilograms of microorganism organic fertilizer and 0.15 to 0.3kilograms of microelement addition agent are added in each cubic meter of the mixture. According to the proportion, grass carbon, peat, vermiculite, perlite, diammonium phosphate, microorganism organic fertilizer and microelement addition agent are put in an agitator after high-temperature sterilization for stirring and sieving, thereby obtaining the nursery substrate. The nursery substrate has the advantages of simple operation, low cost, long fertilizer efficiency and strong seedling, and is particularly suitable for being popularized and used in factory breeding for melon, fruit and vegetable and root stock grafted seedling.

Description

technical field [0001] The invention relates to a solid nutrient substrate for growing melon, fruit and vegetable seedlings. It is mainly suitable for planting seedlings in industrialized plug trays. Background technique [0002] In today's world, due to the rapid development of agricultural vegetable planting technology, vegetable farmers have brought about earth-shaking changes in their planting concepts. Vegetable farmers have changed from buying seeds to buying seedlings, thus promoting the great development of industrial seedling cultivation. At present, there are two main types of solid substrates used in the society: the first one is a mixture of peat and vermiculite, and its formula is a mixture of peat: vermiculite at a ratio of 1:2 (volume ratio). This kind of substrate does not add any nutrients Substance, its nutritional mode has always been watering the nutrient solution. The configuration of this nutrient solution is loaded down with trivial details, and the ...
