Problems solved by technology

In recent years, the application of chemical fertilizers has played a key role in increasing the income of corn, which can meet the growth needs of corn in a short period of time, but long-term use of chemical fertilizers will seriously increase the harmful substances in corn, poor quality, nutritional insufficiency, and make the soil It is easy to harden, has poor drought resistance and poor water retention performance. High seedling emergence rate and early emergence of strong seedlings are the ba

Abstract

The invention discloses a corn drought-resistant compound fertilizer which is prepared from the following raw material components in parts by weight: 18-35 parts of urea, 15-20 parts of ammonium dihydrogen phosphate, 12-18 parts of potassium dihydrogen phosphate, 5-10 parts of sodium selenite, 16-22 parts of humic acid, 10-16 parts of hemp stalk charcoal, 3-8 parts of honeysuckle, 3-5 parts of caragana microphylla, and 2-7 parts of herba ecliptae. The invention also discloses a preparation method of the corn drought-resistant compound fertilizer, wherein the preparation method includes the following steps: S1, weighing all the raw material components respectively for standby application; S2, mixing honeysuckle, caragana microphylla and herba ecliptae, adding water, decocting for 2-4 h, filtering, to obtain filtrate and a filter residue, and concentrating the filtrate to obtain a pasty extract; S3, mixing the pasty extract with humic acid and hemp stalk charcoal to obtain a mixture; andS4, mixing urea, ammonium dihydrogen phosphate, potassium dihydrogen phosphate, sodium selenite and drug dregs powder with the mixture evenly, granulating and drying to obtain the compound fertilizer. The compound fertilizer can improve the drought resistance of soil and the yield of corn is improved.

Description

Technical field [0001] The invention belongs to the technical field of crop fertilizers, and specifically relates to a corn compound fertilizer. Background technique [0002] Corn is the main food crop in my country. It is known as a longevity food. It is rich in protein, fat, vitamins, trace elements, cellulose and polysaccharides. It has become a popular health food and often appears on people’s tables. It has great potential to develop high-nutrient and high-biological functional foods. Corn is also a raw material for feed and future bioenergy. [0003] Corn is a high-yield crop that requires a lot of fertilizer. During its growth and development, it needs to absorb a lot of nutrients, of which nitrogen, phosphorus, and potassium require the most, followed by calcium, magnesium, sulfur, boron, zinc, and manganese. In recent years, the application of chemical fertilizers has played a key role in increasing corn income and can meet the growth needs of corn in a short period of tim...
