Nutrition fertilizer capable of preventing and treating oilseed rape downy mildew

Abstract

The invention discloses a nutrition fertilizer capable of preventing and treating oilseed rape downy mildew. The nutrition fertilizer is prepared from the following raw material ingredients in parts by weight: 15 to 20 parts of alginic acid solution, 8 to 12 parts of calcium chloride, 0.5 to 0.7 part of hexadecyl trimethyl ammonium bromide, 6 to 8 parts of urea, 2 to 4 parts of ascorbic acid, 3 to 5 parts of norflurazon active compound, 0.8 to 1.2 parts of microelement solution, 2 to 3 parts of indolebutyric acid, 1 to 2 parts of auxin, 0.8 to 1.2 parts of boric acid, 0.5 to 0.7 part of ethylenediaminetetraacetic acid ferric sodium salt, 7 to 9 parts of filler and 0.8 to 1 part of Arabic gum. The nutrition fertilizer disclosed by the invention can provide required varieties of nutrients for oilseed rape growth; the microelement solution can provide microelements for oilseed rape and can obviously improve oilseed rape yield; the nutrition fertilizer is safe, reliable and free of pollution, prevents soil from hardening, can reduce chemical fertilizer and pesticide use amount a lot; the norflurazon active compound keeps original speed-kill characteristics of varieties of pesticides, effectively combines an embedding effect with an absorption effect of the pesticides and can kill pests and provide the defined amount of requirement nutrition elements for plants at the same time when being compounded with the filler; the pesticide has wide insecticidal spectrum and further has a persistent effect.

Description

technical field [0001] The invention belongs to the technical field of flower nutrient solution, and in particular relates to a nutrient fertilizer for preventing and controlling rape downy mildew. Background technique [0002] The method of planting rapeseed has moisture, that is direct seeding or raising seedlings. Live broadcasting is mostly used in the north, while seedling cultivation is the main method in the south. Live seeding is often used for large-scale planting, and seedling cultivation is mostly used for small areas. Rapeseed seeds are small, with a thousand-grain weight of 2.5-4g. It is required to prepare the soil carefully, apply enough base fertilizer, and choose different row spacing according to the purpose of use. Use 2.5-40cm row spacing for green feed, and 0.3-0.4kg / mu sowing rate. If it is used for harvesting, increase the row spacing and reduce the sowing rate. Rapeseed can be drilled or broadcast. Rapeseed seedlings need to be seedbed first, the...
