Embodiment 1

[0025] Mix and stir 12.02 parts of urea, 15.99 parts of monoammonium phosphate, 31.58 parts of potassium nitrate, and 9.60 parts of calcium nitrate, 9.33 parts of magnesium sulfate and 0.21 parts of trace element mixture in a fertilizer mixer; add fertilizer grade bentonite to the above two mixtures 20. 31 parts are mixed evenly in a fertilizer mixer, and then packaged separately to obtain a special fertilizer for full-nutrient drip irrigation of cucumbers in existing facilities. The fertilizer contains 0.97% water and meets the production requirements of high-concentration compound fertilizer.

Embodiment 2

[0027] Field application of special fertilizer for cucumber full nutrition drip irrigation:

[0028] The special fertilizer for cucumber full-nutrition drip irrigation for facilities is applied together with cucumber irrigation. The specific method is to weigh the fertilizer according to the cucumber growth process, dissolve it in water and stir to form a fertilizer solution, and use a fertilizer applicator to evenly apply it to the seedbed along with the water supply pipe. 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 compound fertilizer special for drip irrigation of cucumber in a greenhouse, which comprises the following nutritive elements in each hm<-2>: 391.41 kg of N, 255.43 kg of P2O5, 416.91 kg of K2O, 65.25 kg of CaO, 46.50 kg of MgO, 26.46 kg of Fe, 17.60 kg of Mn, 9.70 kg of Cu, 6.46 kg of Zn, 3.00 kg of B and 1.50 kg of Mo. The compound fertilizer special for the drip irrigation of the cucumber in the greenhouse with high applicability is prepared by a physical method through field trails and verification research based on a nutrient preserving capability and a water requirement principle and a nutrient requirement principle of the cucumber.

Description

technical field [0001] The invention belongs to the technical field of new full-nutrient compound fertilizers, and in particular relates to a special mixed fertilizer for drip irrigation suitable for high-quality and high-efficiency cultivation of cucumbers in solar energy-saving greenhouses in arid and cool climate regions in Northwest China 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 s...
