preparation example Construction

[0027] The present invention also provides a method for preparing the special compound fertilizer for jujube drip irrigation, which is characterized in that the preparation steps are as follows:

[0028] a Calculate the respective proportions of urea, monoammonium phosphate, potassium nitrate, potassium sulfate and calcium nitrate according to the effective nutrient content, mix and stir evenly, and set aside;

[0029] B mix and stir magnesium sulfate and micronutrient element, stand-by;

[0030] c. Mix the mixture of the above-mentioned a and b with 15.42% of the total mass of filler fertilizer grade bentonite, and stir evenly to obtain the special compound fertilizer for jujube drip irrigation in the facility.

Embodiment 1

[0032] Mix and stir 27.83 parts of urea, 10.62 parts of monoammonium phosphate, 30.13 parts of potassium nitrate, and 2 parts of calcium nitrate, 2 parts of magnesium sulfate and 12 parts of trace element mixture in a fertilizer mixer; 15. 42 parts are mixed evenly in a fertilizer mixer, and then packaged separately to obtain a special fertilizer for drip irrigation with full nutrition for facility long jujube. The fertilizer contains 0.97% water and meets the production requirements of high-concentration compound fertilizer.

Embodiment 2

[0034] Field application of special fertilizer for jujube full nutrition drip irrigation in the facility:

[0035]The special fertilizer for jujube full nutrition drip irrigation in the facility is applied together with the jujube irrigation water. The specific method is to weigh the fertilizer according to the growth process of the jujube, dissolve it in water and stir to form a fertilizer liquid, and use a fertilizer applicator to evenly apply it to the roots of the jujube along with the water supply pipeline. soil. The amount of fertilizer is gradually increased with the acceleration of the growth process, and the amount of fertilizer is controlled at 1 ton per hectare.

Abstract

The invention discloses a special compound fertilizer for drip irrigation of facility long jujubes and a preparation method thereof. The nutritive elements of the special compound fertilizer and application amounts thereof are as follows: N 184.06 kg/hm<2>; P2O5 65.59 kg/hm<2>; K2O 140.19 kg/hm<2>; CaO 10.98 kg/hm<2>; MgO 6.67 kg/hm<2>; Fe 7.37 kg/hm<2>; Mn 7.28 kg/hm<2>; Cu 8.00 kg/hm<2>; Zn 8.07 kg/hm<2>; B 2.3 kg/hm<2>; and Mo 9.80 kg/hm<2>. The special compound fertilizer provided by the invention overcomes the problems of few nutritive elements, poor dissolvability, a single nutrient, inappropriate proportions of nutritive elements, proneness of incurring soil hardening, unbalanced nutrition, environmental pollution and the like of conventional compound fertilizers; the special compound fertilizer facilitates large-scale promotion of water-saving fertilizer-saving high-efficiency cultivation, takes the nutrient-supplying performance of regional soil into consideration, fully meets nutritional needs of the facility long jujubes, has good targeting performance, reduces waste of fertilizer water, improves the output and quality of the facility long jujubes, enhances the utilization efficiency of limited water resources and fertilizer resources in arid areas, and lowers agricultural production cost.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a special compound fertilizer for facility jujube drip irrigation and a preparation method thereof. Background technique [0002] Water and fertilizer are two key factors limiting crop production in the vast arid and semi-arid regions of Northwest China. One of the key technologies to solve the contradiction of water and fertilizer supply in arid areas is to implement the integrated and precise supply of water and fertilizer under water-saving irrigation. The production of compound fertilizers with good water solubility and strong adaptability can effectively promote the implementation of water and fertilizer integration technology, improve the efficiency of water and fertilizer use, and promote the sustainable development of agriculture in dry areas. [0003] The production of compound fertilizer can materialize fertilization technology, improve fertilizer efficien...
