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

Embodiment 1

[0021] Example 1 Preparation of fertilizer. Mix urea, monoammonium phosphate, potassium nitrate and calcium nitrate in proportions of 45 parts: 6 parts: 17 parts: 2.5 parts, mix and stir well; combine magnesium sulfate, ferrous sulfate, manganese sulfate, copper sulfate, zinc sulfate, borax and molybdenum Ammonium acid in proportions of 2.5 parts: 2 parts: 1.5 parts: 1.5 parts: 1.5 parts: 4 parts: 1.5 parts, mix and stir evenly; add 15 parts of 200-mesh fertilizer grade bentonite to the above two mixtures and mix them evenly in a fertilizer mixer. installed, and obtained the special compound fertilizer for the facility cultivation of winter jujube. The water content of the fertilizer is less than 1%, which meets the production requirements of high-concentration water-soluble fertilizer.

Embodiment 2

[0022] Field application of special fertilizer of embodiment 2: the special compound fertilizer for the facility cultivation of winter jujube is applied together with the irrigation water of winter jujube. The water supply pipe is evenly applied to the root soil of winter jujube. During the whole growth period of winter jujube, the control dosage is 200kg per 666.6m2. The fertilizer has been tested in the field test of winter jujube fertilizer efficiency in the Greenhouse Winter Jujube Base of Horse Farm in Qingxian County, and the comparison test of the yield and quality of winter jujube has been carried out using the compound fertilizer specially used for the facility cultivation of winter jujube in the same solar greenhouse at the same time period and the farmers' routine fertilization. Compared with the conventional fertilization of farmers, the compound fertilizer treatment increases the yield of winter jujube by 13.35% and saves the cost of fertilizer 268 yuan 666.6m 2 ...

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...
