Problems solved by technology
[0002] At present, the means of agricultural production are basically bulk and medium-volume fertilizers, and micro-fertilizers are mostly composed of elemental elements or elemental elements added to macro-element compound fertilizers, and the use efficiency of trace elements is not high
The minimum nutrient ratio of agricultural production points out the contradiction between plant yield and nutrient supply, which shows that fertilization should be targeted, that is, the type of fertilizer should be selected in a targeted manner according to local conditions, what nutrients are lacking, and what fertilizer should be applied. Supplement the minimum nutrient, no matter how much other nutrients are added, it is difficult to increase plant yield, but only waste fertilizer

Embodiment 1
[0008] Embodiment 1: a kind of multi-purpose compound microelement fertilizer is characterized in that mass percentage is composed of: borax 0.6~0.7%, zinc sulfate heptahydrate 4.5~5%, manganese sulfate trihydrate 2~2.2%, ferrous sulfate heptahydrate 0.5-1%, copper sulfate pentahydrate 0.1-0.2%, magnesium sulfate heptahydrate 35-48%, natural dihydrate gypsum 1-1.2%, and the balance is attapulgite.
[0009] The preparation method is as follows: the above-mentioned raw materials are mixed in proportion, and after being fully stirred, granules are made into granules by granulation equipment, and the granule size is 4-5 mesh. After drying, the small bags are sealed and packaged.
[0015] 0.15% copper sulfate pentahydrate, 48% magnesium sulfate heptahydrate, 1.2% natural dihydrate gypsum, and the balance is attapulgite.
[0016] The preparation method is the same as in Example 1.

Abstract
The invention relates to a multipurpose composite trace-element fertilizer which is characterized by consisting of the following components in percentage by mass: 0.6-0.7% of borax, 4.5-5% of zinc sulfate heptahydrate, 2-2.2% of manganese sulfate trihydrate, 0.5-1% of ferrous sulfate heptahydrate, 0.1-0.2% of copper sulfate pentahydrate, 35-48% of magnesium sulfate heptahydrate, 1-1.2% of natural dihydrate gypsum and the balance of attapulgite. The multipurpose composite trace-element fertilizer provided by the invention is stripped layer by layer through hydrolysis, controlled release can be realized, and the elements are in an ionic condition and are favorable for plant absorption; and the fertilizer contains trace elements as well as many beneficial elements. Moreover, the multipurpose composite trace-element fertilizer has strong pertinence, and overcomes the cask effect; and different formulas are adjusted for different crops, and the application range is wide.
Description
technical field [0001] The invention belongs to the field of fertilizers, in particular to a multi-purpose compound micro-element fertilizer. Background technique [0002] At present, agricultural production materials are basically based on bulk and medium-volume fertilizers, and trace elements are mostly composed of simple elements or compound fertilizers with simple elements added to bulk elements, and the use efficiency of trace elements is not high. The minimum nutrient ratio of agricultural production points out the contradiction between plant yield and nutrient supply, which shows that fertilization should be targeted, that is, the type of fertilizer should be selected in a targeted manner according to local conditions, what nutrients are lacking, and what fertilizer should be applied. Supplementing the minimum nutrient, no matter how much other nutrients are added, it is difficult to increase plant yield, but it can only cause waste of fertilizer. Contents of the in...
