Problems solved by technology

In fact, directly using water hyacinth as fertilizer has a very small proportion of nutrients in the substrate, so the fertilizer is very low
The content of nitrogen, phosphorus and potassium in water hyacinth hay is about 3%, 0.4% and 4%, which is far from meeting the fertilization standards

preparation example Construction

[0021] A fertilizer composed of water hyacinth hay and human and animal urine and a preparation method thereof. Including the following steps:

[0022] The first step is to select a water hyacinth plant, cut off the petiole part after drying, and cut it into 1-4cm long sections horizontally or vertically into 1-5mm thick slices to obtain water hyacinth hay slices;

[0023] In the second step, spray human and animal urine on the above-mentioned water hyacinth hay until the hay is completely soaked; at this time, each 1g of water hyacinth hay slice can absorb about 3-4mL of human and animal urine;

[0024] The third step is to dry or air-dry the water hyacinth petiole slices that have absorbed human and animal urine;

[0025] The fourth step is to spray human and animal urine again on the above dried or air-dried water hyacinth hay slices, and then dry or air-dry them again after being soaked; continue to repeat the above urine spraying-drying steps until the water hyacinth gra...

[0030] The steps of the fertilizer preparation method composed of water hyacinth hay and human and animal urine are as follows:

[0031] The first step is to select a water hyacinth plant, cut off the petiole part after drying, and cut it into 1-4cm long sections horizontally or vertically into 1-5mm thick slices to obtain water hyacinth hay slices;

[0032] In the second step, spray human and animal urine on the above-mentioned water hyacinth hay until the hay is completely soaked; at this time, each 1g of water hyacinth hay slice can absorb about 3-4mL of human and animal urine; after that, spray the urine once every 4 hours , when it reaches saturation, the absorption rate of hay to urine is about 400% to 700% [calculation method: (saturated wet weight - initial weight of hay) ÷ initial weight of hay × 100%], that is: using the method of continuous spraying, every 1g Water hyacinth hay slices can absorb up to 4-7mL of urine (see Table 1); it takes about 12 hours to reach sa...

Abstract

The invention discloses a fertilizer consisting of water hyacinth hay slices and human and livestock urea and a preparation method thereof. The preparation method comprises the following steps of: selecting water hyacinth plants, drying in the sun, cutting leaf stalk parts to obtain water hyacinth hay slices, spraying human and livestock urea into the water hyacinth hay slices, fully adsorbing and drying in the sun or drying in the air; repeating the steps until the water hyacinth hay does not have adsorption capacity; and soaking the water hyacinth hay which adsorbs human and livestock urea with water to obtain leachate, diluting the leachate to obtain a fertilizer which can serve as a foliage fertilizer and a soil organic fertilizer and adding remaining water hyacinth hay residues into soil to increase the soil moisture value. By adopting the preparation method, human and livestock urea and water hyacinth which put pressure on the environment are subjected to resource utilization, so that waste is changed into valuable. The obtained fertilizer contains a plurality of rich nutritional ingredients such as natural nitrogen, phosphorus, potassium and the like, is suitable for crop growth, and can be used for enhancing the food health quality and preventing the problems of soil hardening caused by the use of a chemical fertilizer and the like.

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a fertilizer composed of water hyacinth hay and human and animal urine and a preparation method thereof. Background technique [0002] Water hyacinth reproduces rapidly, and consumes a large amount of dissolved oxygen during growth, resulting in deterioration of water quality and affecting the growth of underwater organisms. Famous water bodies such as Dianchi Lake, Taihu Lake, Huangpu River, and East Lake in Wuhan have all experienced water hyacinth flooding, and it is impossible to cure it even after spending huge sums of money. Because water hyacinth only grows in eutrophic water bodies, it is mistakenly considered to be rich in nitrogen, phosphorus, potassium and other elements, and can be directly prepared as organic fertilizer for crop growth. In fact, directly using water hyacinth as fertilizer has a very small proportion of nutrients in the substrate, so...
