Problems solved by technology

However, judging from the development status of my country's agricultural fertilization, there are still the following problems to be solved urgently: First, most of the agricultural fertilizers are still based on general-purpose formulas such as nitrogen-phosphorus-potassium 15-15-15, with the same amount of nitrogen, phosphorus and potassium. It is impossible to apply the same n

Embodiment 1

[0020] Embodiment 1 A special fertilizer for peanuts, with urea (N46%), monoammonium phosphate (N10%-P 2 o 5 50%), potassium sulfate (K 2 Raw materials such as (250%), attapulgite, polyacrylamide and filler are made into the potassium sulfate type high-tower compound fertilizer (N-P 2 o 5 -K 2 O) 20-25-5 (and containing attapulgite 8%, polyacrylamide 8%):

[0021] (1) Enter the urea melting tank after metering to melt into urine, and then send it into the primary mixing tank;

[0022] (2) Send the metered potassium sulfate, monoammonium phosphate, and filler into the primary mixing tank to stir and mix evenly, and the mixed slurry naturally overflows to the secondary mixing tank;

[0023] (3) Add the metered attapulgite and polyacrylamide to the secondary mixing tank to make a mixed slurry;

[0024] (4) The mixed slurry in the secondary tank overflows to the rotary differential granulator, and after spraying and granulating, it naturally cools and falls to the bottom of...

Embodiment 2

[0027] Embodiment 2 is a special fertilizer for peanuts, which is basically the same as in Example 1, except that only urea (N46%), monoammonium phosphate (N10%-P 2 o 5 50%), potassium sulfate (K 2 O 50%), fillers, etc. as raw materials, without adding attapulgite and polyacrylamide to make compound fertilizer (N-P 2 o 5 -K 2 O) 15-20-4.

[0028] Field test: In 2009, the above-mentioned peanut special fertilizer effect test was carried out in the responsible field of Zhao, Chezhao Village, Er'an Township, Neihuang County in 2009. The above-mentioned peanut special fertilizer was applied 35 kg per mu, and the conventional fertilization method (15 kg of general fertilizer nitrogen, phosphorus and potassium per mu) was used. -15-15, 50kg per mu) was used as a control (the field management measures of both were the same), and the double-pod fruit of peanuts using the above-mentioned special fertilizer for peanuts reached 86.6%, an increase of 14.3% compared with the control, ...

Abstract

The invention relates to a special fertilizer for peanut. The special fertilizer for peanut is a composite fertilizer or a compound fertilizer containing nitrogen, phosphor and potassium and has a mass ratio of N to P2O5 to K2O equal to 15-20:20-25:4-5. A formula of the special fertilizer for peanut is reasonable and comprehensive in nutrients, and takes in to integrated consideration on soil nutrition status in Huanghuaihai Region to carry out nutrient element proportion and selection of fertilizer raw materials; the special fertilizer for peanut has a reasonable ratio of nitrogen, phosphor and potassium, satisfies wheat fertilizer requirement rules in a peanut plantation zone in Huanghuaihai Region, has strong pertinency, is easy for operation and can raise fertilizer utilization rate, reduce fertilizer application amount (saving 50-60 yuan for per mu), increase output and improve quality of the crop. After usage of the fertilizer product, double kernel peanut is increased from an original 60-70% to more than 80%; and the special fertilizer for peanut has advantages of reducing agriculture investment, increasing peanut output and raising economic benefit.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special fertilizer for peanuts which increases the double pome fruit of peanuts. Background technique [0002] Peanut is an economic crop, which occupies an important position in our country's national economy. It is the main source of food oil for our people, the main source of plant protein for human beings, an important raw material for the food and pharmaceutical industries, and an important agricultural product for my country's export earnings. For a long time, the agricultural production practice has shown that peanuts use too much nitrogen fertilizer, the growth is vigorous but the yield is low, the single pome fruit is more, the double pome fruit is less, and the yield is low. Therefore, the production of peanut special fertilizer will become the main fertilizer that will provide high peanut yield. It is not only the product of scientific experiments accumulated over the years, but also ...
