preparation example Construction

[0029] As a further embodiment, the preparation method of the selenium-enriched organic fertilizer comprises the following steps:

[0030] Raw material preparation and crushing steps: Weigh 10-15 parts of inorganic selenium source and 1500-1600 parts of organic fertilizer, crush to a size of 50-150 mesh, and set aside;

[0031] Fermentation step: fully mix the crushed inorganic selenium source and organic fertilizer, and then carry out composting fermentation to obtain fermented fertilizer; the control parameters of the fermentation process are as follows: the water content of the fermented fertilizer is 40-50%, the pH value is 7.0-8.0, The temperature is kept at 40-60°C, the humidity is kept at 55-65%, and the fermentation time is 10-30 days;

[0032] The granulation step: feeding the fermented fertilizer into an extruder for granulation, drying at a temperature of 40° C. to 60° C., and then packaging to obtain a selenium-enriched organic fertilizer.

[0033] As a further em...

Abstract

The invention discloses soilless culture nutrient foam cotton for plant planting. The nutrient foam cotton comprises foam cotton and a filling material added into the foam cotton, the filling materialis prepared from, by weight, 35-45 parts of selenium-enriched organic fertilizer, 5-10 parts of peat, 5-10 parts of coco coir, 5-10 parts of vermiculite, 5-10 parts of red jade soil, 5-10 parts of ceramsite, 5-10 parts of clay, 3-5 parts of water retaining agent, 1-5 parts of nitrogen sources, 1-5 parts of phosphorus sources, 1-5 parts of potash fertilizer and 1-2 parts of medium trace element additive. The invention further discloses a preparation method for the soilless culture nutrient foam cotton for plant planting. The soilless culture nutrient foam cotton has the advantages that the moisture and fertility prevention performance is good, the breathability is good, and the foam cotton contains rich selenium and various microelements.

Description

technical field [0001] The invention relates to a soilless culture substrate, in particular to a soilless culture nutrient foam for planting and a preparation method thereof. Background technique [0002] Soilless cultivation uses peat or forest leaf humus, vermiculite and other light materials as the seedling substrate to fix the plants, allowing the plant roots to directly contact the nutrient solution, and adopts the modern seedling technology of mechanized precision seeding for one-time seedling formation. Substrate cultivation is a method with the largest promotion area in soilless cultivation. It fixes the root system of the crop in an organic or inorganic substrate, and supplies the crop nutrient solution through drip irrigation or trickle irrigation. The cultivation medium can be packed into plastic bags, or spread in cultivation ditch or groove. The nutrient solution of substrate cultivation is not circulated, which is called an open circuit system, which can prev...
