Embodiment Construction

[0014] Below in conjunction with the following specific examples the present invention is described in further detail:

[0015] A rapeseed cake multi-effect fertilizer, made by weighing the following raw materials in parts by weight (kg): 250 parts of rapeseed cake, 40 parts of pig manure, 40 parts of chicken manure, 40 parts of corn straw, 40 parts of rice straw, 20 parts, 20 parts of urea, 15 parts of potassium dihydrogen phosphate, 10 parts of diammonium hydrogen phosphate, 10 parts of ferrous sulfate, 5 parts of zinc sulfate, 5 parts of boric acid, 20 parts of rhizobia powder, 15 parts of EM bacterial agent, 4 parts of brown sugar Servings, appropriate amount of water.

[0016] The preparation method of a kind of rapeseed cake multi-effect fertilizer described in the present embodiment comprises the following steps:

[0017] 1) Soak corn stalks and rice stalks for 24 hours, mix them with rapeseed cakes, crush them with a grinder, and mix them evenly with pig manure and ch...

Abstract

The invention relates to a rapeseed cake multi-effect fertilizer and a preparation method thereof. The fertilizer is prepared from the following raw materials in parts by weight: 200-250 parts of rapeseed cakes, 30-40 parts of pig manure, 30-40 parts of chicken manure, 30-40 parts of corn stalks, 30-40 parts of rice straws, 10-20 parts of calcium superphosphate, 10-20 parts of urea, 10-15 parts of monopotassium phosphate, 8-10 parts of ammonium phosphate, 8-10 parts of ferrous sulfite, 3-5 parts of zinc sulfate, 3-5 parts of boric acid, 10-20 parts of rhizobium powder, 8-15 parts of EM fungus, 3-4 parts of brown sugar and a proper amount of water. By adopting organic matter fermentation technology, the prepared rapeseed cake multi-effect fertilizer is not only rich in abundant organic matters and nutritional elements needed during growth of crops, is beneficial to the growth and fruiting of crops and improvement of yield of crops and content of nutritional substances, but also can effectively improve the morbidity resistance of crops, improve the structure, water retention and fertilizer retention and the like of soil, thus being a non-toxic multi-effect fertilizer with good ventilation property.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a rapeseed cake multi-effect fertilizer and a preparation method thereof. Background technique [0002] Rapeseed cake is a by-product of rapeseed oil extraction. It contains high protein and a balanced amino acid composition. Among them, the content of sulfur-containing amino acids, crude fiber, calcium, manganese, zinc, and copper is relatively high. Therefore, it can provide crop growth. Necessary nitrogen, phosphorus and trace elements. However, the simple application of rapeseed cake provides relatively simple nutrition, which cannot effectively meet the needs of crop growth. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide a rapeseed cake multi-effect fertilizer and a preparation method thereof. [0004] To achieve the above object, the technical scheme of the present invention is as follows:...
