Embodiment 1

[0026] Mix and stir 12.87 parts of urea, 16.40 parts of monoammonium phosphate, 58.29 parts of potassium nitrate, and 6.74 parts of calcium nitrate, and set aside, mix and stir 3.22 parts of magnesium sulfate and 0.15 parts of a mixture of micronutrient elements, and stir all the above mixtures in the fertilizer Mix evenly in the container; add 1.39 parts of fertilizer-grade bentonite, mix evenly in the fertilizer mixer, pack separately, and obtain the special fertilizer for full-nutrient drip irrigation of facility grapes. The fertilizer contains 0.97% water and meets the production requirements of high-concentration compound fertilizer.

Embodiment 2

[0028] Field application of special fertilizer for full nutrient drip irrigation of grapes in facilities:

[0029] The special fertilizer for full nutrition drip irrigation of facility grapes is applied together with grape irrigation. The specific method is that according to the growth process of grapes, the fertilizer is weighed, dissolved in water and stirred to form a fertilizer liquid, which is evenly applied to the tree rows with a fertilizer applicator along with the water supply pipeline.

Abstract

The invention discloses special compound fertilizer for drip irrigation of greenhouse grapes, which comprises the following nutrient elements based on fertilization ratio: 164.47kg hm<-2> of N, 77.08kg hm<-2> of P205, 256.47kg hm<-2> of K2O, 24.32kg hm<-2> of CaO, 12.538kg hm<-2> of MgO, 9.30kg hm<-2> of B, 6.36kg hm<-2> of Fe, 4.22kg hm<-2> of Mn, 1.21kg hm<-2> of Cu, 0.38kg hm<-2> of Zn and 0.35kg hm<-2> of Mo. On the basis of soil nutrient-supply characteristic and law of water and nutritional demand of the grapes, the special compound fertilizer for drip irrigation of the greenhouse grapes with strong applicability is obtained by a physical method through field experiments and check research.

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 the high-quality and efficient cultivation of water-saving and fertilizer-saving grapes in a solar energy-saving greenhouse in the arid and cool climate region of 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...
