Problems solved by technology

[0004] In the prior art, due to the increase in the amount of chemical fertilizer application year by year, especially the unbalanced fertilization for a long time, the soil nutrient content is unbalanced, the symptoms of soil nutrient deficiency are prominent, the soil is hardened, the bacteria increase, and the vitality decreases, which makes the fertilizer utilization rate decrease. Decreased flower quality

Embodiment 1

[0013] 1. Take 55g of silkworm excrement, 8g of urea, 12g of potassium dihydrogen phosphate, 20g of attapulgite powder, and 5g of humic acid, which are weight ratios;

[0014] 2. Adjust the water content of silkworm excrement to 55%. On the indoor cement floor, the silkworm excrement is piled up into stacks with a height of 1.2m, a width of 2m, and an unlimited length. In winter, it needs to be covered with straw curtains to keep warm, and the pile is artificially turned once a day to make the material ferment. Evenly, it is also conducive to water evaporation; after 15 days, the water content of the silkworm excrement will drop below 25%, no odor, rotten, grayish brown in color, and the composting is completed; after the composting is completed, it will be sieved to remove impurities and debris, making the silkworm excrement Uniform particle size improves merchandiseability.

[0015] 3. The decomposed dried silkworm excrement is complete and rich in nutrients, but a large amo...

Abstract

The invention discloses a natural mineral matter composite fertilizer, relates to a plant growth fertilizer, and belongs to the fertilizer field. The fertilizer is characterized in that bulk drugs of the fertilizer comprise 35-55wt% of silkworm excrement, 8-37wt% of urea, 5-17wt% of potassium dihydrogen phosphate, 20-45wt% of attapulgite powder and 5-10wt% of humic acid, and the fertilizer is prepared through a step of mixing the above raw materials according to the above weight proportions and a step of reducing the water content to 15-20%. In the invention, the fertilizer efficiency is prolonged; the chemical fertilizer consumption is reduced; and the long-acting flower fertilizer produced through cooperating decomposed silkworm excrement with a chemical fertilizer gives consideration to slowly available nutrients and quickly available nutrients, so the nutritional elements are complete and abundant, and a plurality of essential nutritional elements can be continuously supplied to flowers for a long time, thereby the florescence is prolonged, the disease resistance capability of the flowers is improved, the agricultural production cost is reduced, the quality and the output of agricultural products are improved, soil is improved, and the ecologic environment is protected.

Description

technical field [0001] The invention relates to a plant growth fertilizer, which belongs to the field of fertilizers, in particular to a natural mineral compound fertilizer. Background technique [0002] The normal growth of flowers and other plants requires 16 kinds of nutrient elements. Except carbon, hydrogen, and oxygen can be obtained from air and water, other nutrient elements need to be absorbed by plant roots from the soil. Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It plays a very important role in balancing fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. But it also has some disadvantages, such as its nutrient ratio is always fixed, but the types, quantities and ratios of nutrient elements required by different soils and different crops are varied. Therefore, it is best to test the soil before use to understand the texture and nutrition...
