Problems solved by technology

[0004] At present, the common potato fertilizers on the market have low nutrient utilization and are likely to cause soil environmental pollution and other problems. A patented potato compound fertilizer (10328071.X) uses humate as raw material to prepare compound fertilizer. Currently, humate There are problems such as difficult purification and low purification rate; a patented slow-release organic fertilizer for potatoes and its preparation method (10705687.4) adds additional nitrogen and potassium fertilizers as raw materials for fertilizer preparation, which increases the cost and steps of preparation; Special fertilizer for potatoes (10708535.4) mixes trace elements and farmyard manure to granulate, and has no slow-release effect

Embodiment 1

[0024] A special organic mineral fertilizer for potato made from PAL material, which is made with the following raw materials in the following weight ratio: PAL material 55%, peat 22%, grass plant straw 12%, animal manure 6%, EM strain 1%, urea It consists of 3.5% and 0.5% borax. It includes the following steps:

[0025] Step 1: Air-dried peat and sieved, 50 mesh, water content ≤30%, gramineous plant straws are crushed and cut into granules or small pieces, using a layered stacking method, that is, a layer of gramineous plant stalks, layered and stacked Do not press too tightly, keep enough moisture in the pile to ferment the peat powder, sprinkle a layer of animal manure (the peat ratio is slightly higher), and spray a small amount of EM strain (you can use brown sugar water and EM strain 1:1 in advance) Than), and so on. Generally, within 5-7 days, all the raw materials in the pile will be decomposed, the stench will disappear, and all the pathogenic bacteria, insect eggs, gr...

Embodiment 2

[0030] In the fertilizer efficiency experiment, the tested potato variety was Zaodabai, and the PAL material special fertilizer and control treatment were set up. PAL material special fertilizer treatment uses 45 kg / mu of the potato special fertilizer of the present invention, and the control treatment applies conventional fertilizers (urea, diamine phosphate, potassium sulfate) according to the principle of equal nutrients and equal proportions, all of which are applied as a base fertilizer at one time. No more top dressing in the later period.

[0031] The results showed that: compared with conventional fertilizer, the special fertilizer for potato of the present invention increased the yield by 8.2% and the profitability rate (≥75g) increased by 24.5%; after testing, after applying the special fertilizer for potato, the content of beneficial elements in the potato increased ( If zinc is increased by 9.2%), harmful elements are reduced (such as lead by 5.5%). At the same time,...

Abstract

The invention discloses a special potato organic mineral fertilizer prepared from a PAL material, relates to a fertilizer which adopts a PAL material, that is, modified attapulgite, as a main raw material, and belongs to the field of fertilizer preparation. The special potato organic mineral fertilizer is characterized by being prepared from the following raw materials: a PAL material, peat, grass family plant straw, animal waste, EN bacteria, urea and borax. The special potato organic mineral fertilizer has the beneficial effects that the good adsorption property and the nutrient and water retention property of the PAL material are taken into play, the respiratory action of soil can be improved, a good slow-release property of nitrogen, phosphorus and potassium is achieved, multiple trace elements are enriched, and thus an organic mineral fertilizer can be prepared.

Description

Technical field [0001] The invention relates to a special fertilizer fertilizer, which belongs to the field of fertilizer preparation, in particular to a special organic mineral fertilizer for potatoes prepared from PAL materials. Background technique [0002] Potato, a perennial herbaceous plant in the Solanaceae family, with edible tubers, is the third most important food crop in the world, second only to wheat and corn. Together with wheat, corn, rice, and sorghum, it has become the world's five major crops. The main potato producers are China, Russia, India, Ukraine, and the United States. China is the country with the largest total potato production in the world. In 2015, China will launch the strategy of turning potatoes into staple foods and promote the processing of potatoes into staple foods such as steamed buns, noodles, and rice noodles. Potatoes will become another staple food besides rice, wheat and corn. [0003] In the weakly acidic (pH 5.0-6.5) loose soil, the po...
