Special compound fertilizer for cultivation of winter jujube facilities and preparation method

Abstract

The invention discloses special compound fertilizer for cultivation of winter jujube facilities and a preparation method, and relates to the technical field of soil improvement and compound fertilizer, in particular to special compound fertilizer for cultivation of winter jujube facilities and a preparation method. The special compound fertilizer is prepared from the following fertilizer applyingcomponents of urea, monoammonium phosphate, potassium nitrate, calcium nitrate, magnesium sulfate, ferrous sulfate, manganese sulfate, copper sulfate, zinc sulfate, borax, ammonium molybdate and fertilizer-level bentonite according to a ratio of 45:6:17:2.5:2.5:2:1.5:1.5:1.5:4:1.5:15. The special compound fertilizer has the advantages that the problems of fewer types of nutritional elements, poordissolvability, unreasonable nutrient composition, easiness in soil caking, unbalance of nutrients, and pollution to environment in the existing compound fertilizer are solved; the special compound fertilizer is suitable for large-area popularizing, the targeting purpose is strong, the output of winter jujube is increased, the quality of the winter jujube is improved, the waste of fertilizer and water is reduced, the utilization efficiency of water and fertilizer resource is improved, and the agricultural production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of soil improvement and compound fertilizer, in particular to a compound fertilizer special for the facility cultivation of winter jujube and a preparation method. Background technique [0002] Water and fertilizer are important factors that limit the production of facility agriculture. Most of the existing compound fertilizers have many disadvantages such as few types of nutrients, poor solubility, single nutrients, unreasonable proportions of nutrients, easy soil compaction, nutritional imbalance, and environmental pollution. Can not fully meet the nutritional needs of winter jujube in facilities, it is urgent to develop a targeted method that can reduce the waste of fertilizer and water, increase the yield of winter jujube, improve the quality of winter jujube, improve the utilization efficiency of limited water resources and fertilizer resources in arid areas, and reduce agricultural production costs. on...

AI Technical Summary

Problems solved by technology

The existing soil improvement compound fertilizer patent documents and other related technologies can not play the role of full nutrient fertilization, mainly because the types and proportions of nutrient elements are not suitable for the climate and soil environment in northern my country, and cannot play the due role. High-quality cultivation effect, and most soil improvement compound fertilizers cannot be completely dissolved in water, which will easily lead to blockage of water-saving irrigation systems and scrapping, increasing production costs

Comprehensive analysis of the current technology, it has not been reported that it can be effectively applied to the full nutrient drip irrigation and flushing fertilizer of winter jujube in solar greenhouse facilities in the northern climate zone
