Embodiment 1

[0025] Mix 21.86 parts of urea, 12.4 parts of monoammonium phosphate, 35.4 parts of potassium nitrate, and 11.32 parts of calcium nitrate in a fertilizer mixer; mix 3.56 parts of magnesium sulfate and 0.13 parts of trace element mixture, and mix the above mixture with 18.02 parts Fertilizer-grade bentonite is mixed evenly in a fertilizer mixer, and then packaged separately to obtain a special fertilizer for full-nutrient drip irrigation of facility tomatoes. The fertilizer contains 0.88% water and meets the production requirements of high-concentration compound fertilizer.

Embodiment 2

[0027] Field application of special fertilizer for full nutrient drip irrigation of facility tomato:

[0028] The special fertilizer for full-nutrient drip irrigation of facility tomatoes is applied together with tomato irrigation. The specific method is to weigh the fertilizer according to the tomato growth process, dissolve it in water and stir to form a fertilizer solution, and apply it evenly into 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 a compound fertilizer dedicated for trickle irrigation of greenhouse tomato, comprising the following typs of nutrient elements at the fertilization ratio: 358.90 kg hm<-2> of N, 116.63 kg hm<-2> of P2O5, 311.55 kg hm<-2> of K2O, 77.01 kg hm<-2> of CaO, 18.48 kg hm<-2> of MgO, 6.79 kg hm<-2> of Fe, 4.16 kg hm<-2> of Mn, 1.21 kg hm<-2> of Cu, 0.38 kg hm<-2> of Zn, 0.30 kg hm<-2> of B and 0.15 kg hm<-2> of Mo. Based on the soil fertilizer supplying characteristics, the tomato water requirement rule and the nutrition requirement rule, field test and verification research obtain the compound fertilizer dedicated for trickle irrigation of greenhouse tomato, which has strong applicability and is manufactured by the physical method.

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 water-saving, fertilizer-saving and high-quality tomatoes 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 effic...
