Embodiment 1
[0037] A kind of cotton field organic and inorganic compound fertilizer, it is made of the mass fraction of following raw materials:
[0038]
[0039]
[0040] A kind of preparation method of organic-inorganic compound fertilizer of the present embodiment comprises the steps:
[0041] (1) Use a pulverizer to crush the organic matter into debris with a particle size of less than 1cm, take a certain amount of the above-mentioned organic matter debris and put it in a reaction kettle, add a certain amount of water, and then heat at 100°C for 1 hour;
[0042] (2) urea, monoammonium phosphate, potassium sulfate, and potassium chloride are dissolved in turn by condensed water and reflux water to prepare a homogenate A for subsequent use;
[0043] (3) Dissolving and mixing urea formaldehyde, complex zinc iron, amino acid chelated boron, amino acid chelated calcium, mineral source humic acid, humic acid chelated magnesium, complex sodium nitrophenolate into homogenate B, and set ...
Embodiment 2-7
[0046] A kind of cotton field organic-inorganic compound fertilizer, it is made by the mass fraction (%) of following raw material:
[0047]
[0048]
[0049] The preparation steps of the cotton field organic-inorganic compound fertilizer of embodiment 2-7 are the same as embodiment 1.
Embodiment 8
[0051] A kind of application method of organic-inorganic compound fertilizer in cotton field:
[0052] In 2016 and 2017, in a mature cotton field in the Yellow River Basin, the base fertilizer was applied in spring, and two treatments were designed in the large-scale experiment. Treatment 1 was to apply 50kg of Example 1 (TE-11-9-9.5) per mu, and N and P per mu. 2 o 5 、K2 O nutrient input amount is 5.5kg, 4.5kg, 4.75kg; 2 o 5 、K 2 (7.5kg, 7.5kg, and 7.5kg were applied per mu), and 20kg of urea was applied per mu at the initial flowering stage, and the seed cotton yield was actually harvested during the harvest period, and the lint yield was measured.

Abstract
The invention discloses organic and inorganic compound fertilizer for a cotton field and a preparation method thereof. The organic and inorganic compound fertilizer for the cotton field is prepared from organic matters, mineral-sourced humic acid, urea formaldehyde, urea, ammonium carbonate, monoammonium phosphate, potassium sulfate, potassium chloride, compound zinc and iron, amino acid chelatedboron, amino acid chelated calcium, amino acid chelated magnesium, compound sodium nitrophenolate, attapulgite powder and sodium silicate according to a certain ratio. The organic and inorganic compound fertilizer disclosed by the invention can meet the requirements of the growth of cotton on nitrogen, phosphorus and potassium, but also can be used for supplementing medium and trace elements including calcium, magnesium, boron, iron, zinc and the like; the organic and inorganic compound fertilizer also contains the organic matters and the humic acid and is more suitable for being applied to soil with relatively low organic matter content; secondly, the organic matters have a wide source and are easy to obtain; anaerobic carbonization treatment before processing also can be used for killingharmful microorganisms very well; after application, other negative influences are not generated; and condensed water and refluxing liquid in a processing process can be used for dissolving other substances and processing wastewater is not discharged to pollute the environment.
Description
technical field [0001] The invention belongs to the technical field of fertilizers, and more specifically relates to an organic-inorganic compound fertilizer for cotton fields, and also relates to a preparation method for organic-inorganic compound fertilizers for cotton fields. technical background [0002] Cotton, as an important field economic crop, is found in Xinjiang Autonomous Region and Gansu Province in Northwest my country, Shandong, Hebei, Henan, and Shanxi Provinces in the Yellow River Basin, Hunan Province, Hubei Province, Jiangxi Province, Anhui Province, and Jiangsu Province in the Yangtze River Basin. It is planted in all provinces (Wang Ruohai, Division and Changes of China's Cotton Regions, China Cotton, 2009 (9): 12-16). Due to my country's vast territory, large span of longitude and latitude, and obvious altitude difference, each cotton-growing province (region) has a different climate and soil conditions. Among them, the Xinjiang Autonomous Region is mai...
