Problems solved by technology

[0010] Still another object of the present invention is to provide a kind of cotton seedling stage foliage fertilizer in the cotton seedling stage carrying out the application of foliar spraying, through the pot experiment and the field plot test verification, solved cotton seedling stage due to low temperature, poor root system development. Sufficient and weak photosynthetic ability lead to insufficient nutrient absorption, growth retardation, poor stress resistance, weak seedlings, diseased seedlings and other technical problems, which have effectively improved the yield and quality of cotton

Embodiment 1

[0077] A kind of foliar fertilizer suitable for cotton seedling stage, it is made of the mass fraction of following raw materials:

[0078]

[0079] Sodium Lauryl Sulfate 0.5

[0080] Nitrogen (N) and phosphorus (P) of the above cotton seedling foliar fertilizer 2 o 5 ), potassium (K 2 O), magnesium (Mg) content is:

[0081]

[0082] A preparation method suitable for cotton seedling foliar fertilizer, the steps are:

[0083] A, first utilize pulverizer to pulverize urea and urea phosphate respectively and sieve 50 or 55 or 60 or 65 or 70 mesh;

[0084] B. Fully mix the pulverized and sieved urea, ammonium sulfate, ammonium dihydrogen phosphate, and 1 / 3 potassium sulfate with a three-dimensional mixer to make a premix 1;

[0085] C. Using a three-dimensional mixer to fully mix potassium acetate, potassium dihydrogen phosphate, potassium fulvic acid, potassium sulfate and 2 / 3 potassium sulfate to make premix 2;

[0086] D, finally utilize premix 1, premix 2 and the u...

Embodiment 2 to Embodiment 13

[0090] A kind of foliar fertilizer suitable for cotton seedling stage, it is made of the mass fraction (%) of following raw material:

[0091]

[0092] Its preparation steps are identical with embodiment 1.

[0093] For the growth characteristics of cotton under different cotton production areas and different planting modes (direct direct seeding or transplanting), Example 2-Example 13 are respectively high nitrogen, high phosphorus, high potassium, high nitrogen phosphorus, high phosphorus and potassium series formulas. The selection and dosage of each raw material in the formula are determined according to the actual physical and chemical properties, so as to effectively avoid changes in fertilizer properties and loss of nutrient functions due to antagonism and moisture absorption. Potassium sulfate and sodium carbonate, which can improve nutrients, are innovatively used as anti-caking agents and dispersants, fully exploiting and utilizing the functions of raw materials. ...

Embodiment 14

[0095] A kind of hygroscopic law suitable for cotton seedling foliage fertilizer is characterized in that:

[0096] Using urea and potassium fulvic acid as controls, in an incubator with an ambient temperature of 30°C and a relative air humidity of 63%, the hygroscopicity of cotton foliar fertilizers was studied. Use disposable paper cups, each containing 10.00g of urea or potassium fulvic acid or cotton seedling foliar fertilizer, randomly arrange the positions, open the culture, and cover them at 0h, 0.5h, 1h, 2h, 6h, 12h, 24h, 48h The lids were weighed, the mass was recorded, and each treatment was repeated 6 times.

[0097] The results show that potassium fulvic acid has obvious moisture absorption phenomenon in 0.5h, and the surface is dark and moist, and the surface layer is gelatinous after 48h; The surface layer is agglomerated; the quality of the cotton seedling foliar fertilizer only increases by 0.03g during the 48h cultivation process; it shows that through reason...

Abstract

The invention discloses a leaf fertilizer suitable for a cotton seedling stage and a preparation method and an application thereof; the leaf fertilizer is composed of urea, urea phosphate, ammonium sulfate, ammonium dihydrogen phosphate, monopotassium phosphate, potassium sulfate, potassium acetate, potassium fulvate, magnesium sulfate, sodium carbonate and lauryl sodium sulfate. The preparation method comprises the steps: A, firstly, respectively crushing urea and urea phosphate by using a pulverizer; B, mixing crushed and screened urea, ammonium sulfate, ammonium dihydrogen phosphate and 1 / 3of potassium sulfate into a premixed material by using a three-dimensional mixing machine; C, mixing potassium acetate, potassium dihydrogen phosphate, potassium fulvate, potassium sulfate and 2 / 3 ofpotassium sulfate into a premixed material by using the three-dimensional mixing machine; and D, mixing the premixed materials with the crushed and screened urea phosphate, sodium carbonate and lauryl sodium sulfate, to obtain the cotton seedling stage leaf fertilize. Through field validation, the formula is reasonable, the method is easy to implement, and the problems of nutrient absorption deficiency, slow growth retardation, poor resistance ability, weak seedlings and diseased seedlings caused by low temperature, insufficient root system development and relatively weak photosynthetic capacity at the cotton seedling stage are solved.

Description

technical field [0001] The invention belongs to the technical field of foliar fertilizer, more specifically relates to a kind of foliar fertilizer suitable for cotton seedling stage, also relates to a kind of preparation method of seedling stage foliage fertilizer, and also relates to a kind of seedling stage foliage fertilizer on cotton use. Background technique [0002] As an important economic crop, cotton has a long history of cultivation in my country. At this stage, my country is still the world's largest cotton production, consumption and trade country, please see: Yu Shuxun. my country's cotton production status and development trend. China Engineering Science, 2013 (4): 9-1. my country's cotton planting area is vast, and the main cotton planting provinces are Xinjiang, Shandong, Hebei, Hunan, Hubei, Jiangxi Province, Anhui, and Jiangsu (autonomous region). The cotton planting area and output account for about 85% of the country's total. For the three major cotton r...
