Problems solved by technology

[0005] Facility pepper is a vegetable with a large cultivation area in Northwest facilities. However, the habit of using large amounts of water and fertilizers in production practice not only often leads to reduced yields, but also causes obstacles to continuous cropping in greenhouse soil and leads to environmental pollution.

Embodiment 1

[0026] Mix and stir 25.55 parts of urea, 18.14 parts of monoammonium phosphate, 38.36 parts of potassium nitrate, and 4.71 parts of calcium nitrate, and set aside, mix and stir 9.33 parts of magnesium sulfate and 0.21 parts of micronutrient elements, and put all the above mixture in a fertilizer mixer Mix evenly inside; add 2.83 parts of fertilizer-grade bentonite, mix evenly in a fertilizer mixer, pack separately, and obtain the special fertilizer for full-nutrition drip irrigation of capsicum in existing facilities. 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 pepper in facilities:

[0029] The special fertilizer for pepper full nutrition drip irrigation in facilities is applied together with pepper irrigation. The specific method is that according to the growth process of pepper, the fertilizer is weighed, dissolved in water and stirred to form a fertilizer liquid, and evenly applied to the seedbed with the water supply pipe with a fertilizer applicator. 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 special compound fertilizer for drip irrigation of greenhouse pepper, which comprises the following nutrient elements based on fertilization ratio: 586.04kg hm<-2> of N, 255.69kg hm<-2> of P2O5, 506.46kg hm<-2> of K2O, 48.02kg hm<-2> of CaO, 60.06kg hm<-2> of MgO, 25.20kg hm<-2> of Mn and 0.27kg hm<-2> of Cu. On the basis of soil nutrient-supply characteristic and law of water and nutritional demand of the pepper, the special compound fertilizer for drip irrigation of the greenhouse pepper 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 high-quality and high-efficiency cultivation of capsicum in a solar energy-saving greenhouse in a dry and cool climate area 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 sus...
