Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to better understand the technical solutions, the technical solutions will be described in detail with reference to specific embodiments.
Example 1:
the embodiment provides a manufacturing method of a fertilizer special for eucalyptus, which comprises the following steps:
s1: humidifying basic fertilizer in a barrel through a certain amount of water or steam, then carrying out sufficient chemical reaction, and under a certain liquid phase condition, generating extrusion force among material particles to agglomerate into balls by virtue of the rotary motion of the barrel;
s2: according to the requirement, several kinds of fertilizer raw material dry powder are selected for metering and mixing, and a binder is used as a cementing material to be granulated in a granulator;
s3: the dry powder mixture is granulated by heating, adding water or steam to increase liquid phase amount, and rolling while agglomerating in disc or drum to obtain compound fertilizer particles with certain size.
As a preferable scheme, the fertilizer raw materials in step S2 are:
urea, ammonium chloride, diammonium, calcium magnesium phosphate fertilizer and potassium chloride are mixed according to the proportion of N-P-K: 19-9-12, adding 1000PP of borax, 800PP of zinc sulfate, 500PP of copper sulfate, 1000PP of magnesium sulfate, 3 percent of potassium humate and 1000PP of fertilizer synergist.
Preferably, the granulation heating temperature of the dry powder mixture in step S2 is in the range of 50-80 degrees.
As a preferable mode, in step S3, when the water vapor is added, the water content is controlled to be 2.5% to 7.5%.
Fertilizer nitrogen-phosphorus-potassium special for eucalyptus: 19-9-12 parts of boron 1000PP, zinc 800PP, copper 500PP and magnesium 1000PP, and fully meets the requirements of eucalyptus growth on various nutrients in various periods. The main elements absorbed by eucalyptus are: nitrogen, phosphorus, potassium, calcium, magnesium, zinc, boron, and the like. According to research, eucalyptus absorbs 36 g of nitrogen, 2.8 g of phosphorus, 20 g of potassium, 31 g of calcium and 8.5 g of magnesium per year on average, the absorption amounts are that nitrogen is greater than calcium, potassium is greater than magnesium, and the absorption ratio of nitrogen, phosphorus and potassium is 13: 1:8. The eucalyptus is green or purple-red due to nitrogen deficiency, the growth is hindered, the eucalyptus is weak and easy to fall down due to potassium deficiency, and the leaf color is dark and dull; calcium and magnesium element grams increase the resistance of the eucalyptus, so that the eucalyptus grows quickly, the tree shape is straight and uniform, and the yield is high; the zinc and boron elements promote the growth of the top end of the eucalyptus, if the two elements are lacked, the eucalyptus has the defects that the top end is dry, tender buds of the eucalyptus are swollen and crisp, the eucalyptus is easy to wind and break, weak and small branches are formed, and the like, so that the growth of the eucalyptus is seriously influenced.
Adding mineral humic acid
(1) Improving the soil; the humic acid organic colloid can be used for cementing soil particles, so that water-stable aggregates in soil are increased, and the water, fertilizer, gas and heat conditions of the soil are coordinated. Humic acid can absorb and adsorb soluble salt of soil, adsorb and retain a large amount of harmful cations, and reduce the pH value of the saline alkali.
(2) The fertilizer efficiency is improved; as humic acid can adsorb and exchange and activate a plurality of mineral elements in soil. Such as: phosphorus, potassium, calcium, magnesium and the like, so that the fertilizer can play a role of a synergist in the fertilizer.
(3) Stimulating the growth of crops; humic acid contains various functional groups, and as a physiologically active substance, the humic acid has stimulation effects on the growth and development of crops and physiological metabolism in vivo.
(4) Disease resistance function; the microorganism provides an excellent environment for identification, beneficial population gradually develops into dominant population, production of harmful germs is inhibited, and the promotion effect of metabolism of plants can improve immunity, so that diseases are greatly reduced.
(5) The stress resistance of crops can be improved, a plurality of factors such as soil, moisture, nutrients, humidity, illumination, air and the like in the growth environment of the crops form the growth conditions of the plants, humic acid plays a buffering role, and the adverse effect of the growth of the crops is reduced.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
