Abstract

The invention belongs to the field of fertilizers, and particularly relates to a peanut fertilizer. The peanut compound fertilizer comprises urea, calcium phosphate, potassium chloride, monopotassium phosphate, other microelements and beneficial bacterium. The compound fertilizer aims at the requirements of growing of the peanut, increases organic components and microorganism, reduces the negative effects of excessive use of fertilizer to the salinity of the soil, provides enough nutrition for growing of the peanut with few times of application, also can improve the soil and the fertility of the soil.

Description

One composite fertilizer of cultivating peanut

Technical field

The invention belongs to chemical fertilizer field, be specifically related to the composite fertilizer of cultivating peanut.

Background technology

Peanut has another name called Semen arachidis hypogaeae, belongs to Papilionaceae Arachis annual herb plant.Peanut is one of main farm crop of China, and peanut is described as " Vegetable meat " by people, and oleaginousness is up to 50 parts, best in quality, smell delicate fragrance.Except edible, also, for printing and dyeing, paper industry, peanut is also a herb, and the cultivation management technology of peanut is also relatively strong; The nutrient that peanut needs mainly contains nitrogen, phosphorus, potassium, 4 kinds of elements of calcium, and peanut is leguminous crop, and root has root nodule, the nitrogen in energy fixed air.The nitrogen 2/3 that peanut needs is in life fixed by root nodule bacterium.Inorganic fertilizer is mainly used in peanut fertilising now, causes soil salt alkalescence, causes soil fertility to decline, and affects the growth of peanut.

Summary of the invention

For solving the above-mentioned shortcoming of prior art, the invention provides the composite fertilizer of cultivating peanut, pointedly the required nutrient of peanut in soil is supplemented, added organic composition, supplemented microorganism, soil fertility has been improved, improve the fertility of soil, reduce the saline alkali of soil.

The present invention is achieved through the following technical solutions:

One composite fertilizer of cultivating peanut, by weight, comprise: urea 25-40 part, calcium phosphate 22-30 part, Repone K 8-14 part, potassium primary phosphate 12-25 part, magnesium sulfate 2-5 part, Manganous chloride tetrahydrate 0.5-2 part, ferrous sulfate 1-3 part, borax 0.8-2 part, cow dung 4-8 part, pig manure 2-5 part, chicken manure 2-5 part, EM bacterium 0.5-1 part;

Make to prepare with the following method: (1), cow dung, pig manure, chicken manure is broken, trickle is wetting, and making its water content is 20%, and access EM bacterial classification, mixes, and uses film to cover, fermentation 8-15 days; (2), urea, calcium phosphate, Repone K, potassium primary phosphate, magnesium sulfate, Manganous chloride tetrahydrate, ferrous sulfate, borax are mixed with the above-mentioned fertilizer fermenting, obtain composite fertilizer.

Use the peanut composite fertilizer of this formula, every mu of fertilising 25-30kg, can provide enough nutritive ingredients for peanut, and can improve soil.

Beneficial effect of the present invention: the demand of peanut growth of the present invention, composite fertilizer's formula is provided targetedly, organic composition and microorganism in composite fertilizer have been increased, reduced excessive use chemical fertilizer the saline alkali of soil has been caused to negative impact, in less fertilising, for the growth of peanut provides enough nutriment, can improve soil simultaneously, improve the fertility of soil.

Embodiment

Embodiment 1

One composite fertilizer of cultivating peanut, by weight, comprising: 39 parts, urea, 15 parts, calcium phosphate, 12 parts, Repone K, 18 parts of potassium primary phosphates, 2 parts, magnesium sulfate, 1 part of Manganous chloride tetrahydrate, 1 part, ferrous sulfate, 1 part of borax, 5 parts of cow dungs, 2 parts of pig manures, 3 parts of chicken manures, 1 part of EM bacterium.Make to prepare with the following method: (1), cow dung, pig manure, chicken manure is broken, trickle is wetting, and making its water content is 20%, and access EM bacterial classification, mixes, and uses film to cover, and keeps internal temperature at 28-35 ℃, ferments 15 days; (2), urea, calcium phosphate, Repone K, potassium primary phosphate, magnesium sulfate, Manganous chloride tetrahydrate, ferrous sulfate, borax are mixed with the above-mentioned fertilizer fermenting, obtain composite fertilizer.

Embodiment 2

One composite fertilizer of cultivating peanut, by weight, comprise: 25 parts, urea, 24 parts, calcium phosphate, 14 parts, Repone K, 14 parts of potassium primary phosphates, 3 parts, magnesium sulfate, 2 parts of Manganous chloride tetrahydrates, 2 parts, ferrous sulfate, 2 parts of boraxs, 6 parts of cow dungs, 4 parts of pig manures, 3 parts of chicken manures, 1 part of EM bacterium, method makes described in embodiment 1.

Embodiment 3

One composite fertilizer of cultivating peanut, by weight, comprise: 28.5 parts, urea, 23 parts, calcium phosphate, 8 parts, Repone K, 24 parts of potassium primary phosphates, 3 parts, magnesium sulfate, 0.5 part of Manganous chloride tetrahydrate, 2 parts, ferrous sulfate, 1.5 parts of boraxs, 4 parts of cow dungs, 2 parts of pig manures, 3 parts of chicken manures, 0.5 part of EM bacterium, method makes described in embodiment 1.

Inorganic peanut composite fertilizer (main component is: urea, calcium phosphate, Repone K, potassium primary phosphate) simultaneous test on above-described embodiment and existing market, plants respectively 3 mu of Shandongs and spends peanut experimental plot No. 16, and result is as following table:

Table 1

?	Rate of fertilizer application (kg/ mu)	Per mu yield (kg)	Units increased in production (kg)	Stimulation ratio
					Comparative example	28kg	325kg	——	0
Embodiment 1	28kg	432kg	107	32.9%
					Embodiment 2	28kg	425kg	100	30.7%
Embodiment 3	28kg	409kg	84	25.8%

As shown in Table 1, after peanut provided by the invention composite fertilizer is used with respect to composite fertilizer in comparative example, peanut yield obviously improves, and use this fertilizer after 3 years, and detecting salts contg in soil and show, in soil, salts contg reduces by 18.7%, reduce salting of soil degree, promoted the fertility of soil.
