Embodiment 1

[0028] Embodiment 1 A special fertilizer for cucumber, 350kg urea (N46%), 60kg monoammonium phosphate (N10%-P 2 o 5 50%), 440kg potassium sulfate (K 2 (250%), 50kg filler, 60kg fertilizer synergist is made the potassium sulfate type tall tower compound fertilizer 17-6-22 ( N-P 2 o 5 -K 2 O):

[0029] 1. After the urea is measured, enter the urea melting tank to melt it into urine, and then send it to the primary mixing tank;

[0030] 2. Send the measured 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;

[0031] 3. Add the metered nitrogen fertilizer synergist into the secondary mixing tank to make a mixed slurry;

[0032] 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 the tower to form compound fertilizer granules;

Embodiment 2

[0041] Embodiment 2 A kind of special fertilizer for cucumber, with 350kg urea (N46%), 60kg monoammonium phosphate (N10%-P 2 o 5 50%), 440kg potassium sulfate (K 2 (250%), 30kg filler, 80kg fertilizer synergist is made the potassium sulfate type high tower compound fertilizer (17-6-22) that meets GB15063-2001 standard by the method for embodiment 1.

[0042] The above-mentioned fertilizer synergist is attapulgite modified by ultrasonic modification, and its preparation method is as follows:

[0043] Put the attapulgite (origin: Xuyi County, Jiangsu Province) with a particle size of 200 and a viscosity Mpas (centiPas) ≥ 2000 into an ultrasonic generator, and irradiate it with 35KHz ultrasonic waves for 4 minutes.

[0044] The field test carried out with the above-mentioned special fertilizer for cucumber is as follows:

[0045] 1. The test site is Wangyue Village, Xushui Town, Zhengzhou City, with a demonstration area of ​​600m 2 .

[0046] 2. The experimental design set u...

Embodiment 3

[0050] Embodiment 3 A special fertilizer for cucumber is a compound fertilizer containing nitrogen, phosphorus and potassium, wherein N:P 2 o 5 :K 2 The weight ratio of O is 1:0.4:1.2, and the compound fertilizer contains 5% fertilizer synergist, that is, attapulgite (particle size is 300 mesh, viscosity Mpas≥2000 cPas) irradiated by 33KHz ultrasonic waves for 4.5 minutes. Using liquid ammonia as the nitrogen source, calcium superphosphate / double superphosphate as the phosphorus source, potassium sulfate as the potassium source, adding 5% ultrasonically modified attapulgite and appropriate amount of diatomaceous earth to make a compound that meets national standards Fat (15-6-18).

Abstract

The invention relates to a fertilizer specially used for cucumbers, aiming at providing a fertilizer used for cucumbers with reasonable mixture ratio of N, P and K, high utilization ratio of nutrient and nutrient release rate conforming to the fertilizer requiring rule of cucumbers. The technical proposal is that: the weight ratio of N : P2O5 : K2O in a compound / mixed fertilizer is 1 : 0.2 to 0.5 : 1.2 to 1.6, the compound / mixed fertilizer contains 4 to 10 percent of fertilizer synergist, and the fertilizer synergist is attapulgite irradiated by ultrasonic wave of more than 20KHz and less than 50KHz for 1 to less than 5 min. The fertilizer specially used for cucumbers has wide applicability, can meet the requirement of the cucumbers in a whole growing season and is applied as a base fertilizer for one time, with obvious fertilizer-saving and production-increasing effects.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special fertilizer for cucumbers. Background technique [0002] Cucumber is a popular melon vegetable, and it is one of the main vegetables produced in the open field and in the greenhouse in the northern region. In recent years, due to people's blind pursuit of high yield and blind application of large amounts of fertilizer, the application ratio of nitrogen, phosphorus and potassium has been seriously out of balance, resulting in the accumulation of soil salt and waste of fertilizer. High fertilization means high loss of fertilizer, resulting in more serious environmental problems. According to reports, the utilization rate of nitrogen fertilizer in my country is about 30% to 50%, the utilization rate of phosphorus fertilizer is about 10% to 15%, and the utilization rate of potassium fertilizer is about 30% to 60%. There are many reasons for the low utilization rate of chemical fertilizers, o...
