Embodiment 1

[0022] Embodiment 1: a kind of special foliar fertilizer for spring rape, comprising the following components in mass percentage: urea 40%, ammonium polyphosphate 8%, potassium dihydrogen phosphate 12%, chitosan oligosaccharide 20%, EDTA chelated magnesium 3%, EDTA chelated zinc 2%, EDTA chelated calcium 10%, boric acid 5%, the sum of the mass percentages of the above components is 100%.

[0023] The production method of special foliage fertilizer for spring rape in this embodiment is as follows: take each raw material according to the formula ratio requirements, fully grind the raw material, pass through a sieve of more than 80 mesh, then put each component into a stirring mixer and mix evenly, quantitative packaging is ready. Can.

[0024] In this embodiment, the application rate of the special foliar fertilizer for spring rape is 1.0-1.5 kg / mu, and it is generally diluted with water to 100-150 times the liquid, and an appropriate amount of surfactant is added for spraying. ...

Abstract

The invention discloses a foliar fertilizer special for spring rape. The foliar fertilizer is prepared from the following raw material components: urea, ammonium polyphosphate, monopotassium phosphate, chitosan oligosaccharide, EDTA (Ethylene Diamine Tetraacetic Acid) chelated magnesium, EDTA chelated zinc, EDTA chelated calcium and boric acid. Aiming at the characteristics that the spring rape grows quickly from the seedling stage to the stem elongation stage and the nutrient demand intensity is relatively high, the special foliar fertilizer for the spring rape is prepared by reasonably matching the components such as macronutrient elements, medium and trace nutrient elements, a plant growth regulator and the like according to the nutrient demand characteristics of the spring rape in the seedling stage; the fertilizer can be rapidly absorbed and utilized by plants after being sprayed in the spring rape seedling stage, formation of branches and siliques of the spring rape is remarkably promoted, finally the yield and quality of the spring rape are remarkably improved, and the fertilizer utilization rate is high; and meanwhile, the special foliar fertilizer for spring rape is simple in preparation method, low in cost, convenient to apply and suitable for large-scale mechanical operation.

Description

Technical field: [0001] The invention relates to the technical field of fertilizers, in particular to a special foliar fertilizer for spring rape. Background technique: [0002] Rapeseed (Brassica napus L.) is the world's largest oil crop, not only the main source of edible oil, but also an important industrial raw material and protein feed. Rapeseed is an important oil crop in my country. The planting area and total output of rapeseed in my country ranks second in the world, second only to Canada. In 2018, the total sown area of ​​rapeseed in my country was 6.551 million hectares, and the total output reached 13.281 million tons, accounting for 38.7% of the total output of oilseed crops (China Statistical Yearbook, 2019). However, the supply of edible oil in my country is still seriously insufficient, the self-sufficiency rate is only above 40.6%, and the contradiction between supply and demand is becoming increasingly prominent. Therefore, it is a top priority for my cou...
