After a proper amount of rapeseed cake is mixed with planting soil, it is poured with water and sealed. Can be placed in a bright place, can be decomposed and fermented in 3-6 months, and can be used directly. Rapeseed cake is a kind of high-quality organic fertilizer, which refers to the by-product produced after rapeseed is extracted and pressed. Rotten rapeseed cakes can be stacked in 3-4 layers for decomposition, and each layer is generally 20-30cm high.

First, how to use rapeseed cake as fertilizer

1. First, mix a proper amount of rapeseed cake with planting soil, water it, seal it, and then put it in a well-lit place for about 3-6 months to decompose and ferment. You can use it directly at this time. You can also put a small amount of rapeseed cake at the bottom of the flowerpot as the base fertilizer, and you must not contact with the crop roots.

2. Rapeseed cake mainly refers to the by-product produced after rapeseed is harvested and pressed. It is a high-quality organic fertilizer. Rapeseed cake not only plays a great role in agricultural production, but also promotes the growth of crops. Rapeseed cake absorbs a lot of water when it decomposes. Before decomposition, enough water must be absorbed, so that it can be decomposed quickly, and most nutrients are inorganic, which is easier to be absorbed and utilized by crops.

3. At present, rotten rapeseed cakes can be piled up. Generally, 3-4 layers are piled, each layer is 20-30cm high, and each pile 1 layer can be sprayed with 1 times of organic fertilizer decomposing agent. The height of the pile is about 1 m, which must not be too high to prevent the heat in the pile from being suffocated, and it must be covered with film after the pile is finished.

Second, what kind of fertilizer does the vegetable cake fertilizer belong to?

1. Rapeseed cake fertilizer is a kind of organic fertilizer, which is mainly composed of rapeseed cake, sesame cake, bean cake and other cakes through high-temperature fermentation and decomposition. There are two ways to obtain cake fertilizer, one is to buy fermented cake fertilizer, and the other is to have bean cakes at home and ferment them yourself.

2. When the vegetable cake fertilizer is used as topdressing, it must be fully crushed and ditched, but attention should be paid to keeping a proper distance from the plant root system to avoid the heat generated during the fermentation of the cake fertilizer from burning the seedlings. Using vegetable cake fertilizer as topdressing will last longer and have better effect than chemical fertilizer.

3. Rapeseed cake fertilizer is more suitable for clivia, chlorophytum, rose, rose, radish, gardenia, camellia, longevity flower and other crops. Be sure to decompose it before using it. Because of the high nutrient content and fast decomposition and decomposition of cake fertilizer, if it is used directly, it will produce a large number of hyphae in the soil and consume a lot of oxygen, which will not only block soil pores, but also affect soil permeability.
