Slow-release and high-yield fertilizer special for cucumbers

Abstract

The invention discloses slow-release and high-yield fertilizer special for cucumbers. The slow-release and high-yield fertilizer is prepared from, by weight, 20-40 parts of composite film-coated urea, 5-15 parts of ammonium nitrate, 20-40 parts of monoammonium phosphate, 40-80 parts of potassium sulphate, 5-15 parts of potassium chloride, 1-2 parts of calcium hydrophosphate, 0.1-0.5 part of sodium silicate, 0.1-0.5 part of EDTA chelated zinc, 0.2-0.6 part of diaminoferric xanthohumate, 0.1-0.4 part of EDTA chelated zinc, 40-80 parts of composted chicken manure, 20-40 parts of molasses powder, 20-40 parts of grass carbon, 5-15 parts of decomposed coal, 5-15 parts of kaolin, 0.001-0.007 part of bacillus subtilis, 0.02-0.05 part of bacillus licheniformis and 0.005-0.009 part of paenibacillus polymyxa. By means of the slow-release and high-yield fertilizer, no topdressing needs to be conducted after one-time fertilization, the fertilizer efficiency is remarkable and durable, the slow release effect is good, the soil structure can be improved, nutrient elements required for growth of cucumbers are provided, and yield of cucumbers is high.

Description

Technical field [0001] The invention relates to the technical field of cucumber fertilizer, in particular to a slow-release and high-yield special fertilizer for cucumber. Background technique [0002] Cucumber is one of the main vegetables commonly eaten by people in the north and south of our country. Cucumber production has good economic and social benefits. However, due to the limitation of the amount of arable land, climatic conditions, and the pursuit of high yield and efficiency, it has been difficult to grow it for many years. When it comes to crop rotation, the physical and chemical properties and nutritional balance of the soil are destroyed. Summary of the invention [0003] The present invention provides a slow-release high-yield cucumber special fertilizer, one-time fertilization does not require top dressing, the fertilizer effect is significant and lasting, the slow-release effect is good, the soil structure can be improved, the nutrient elements required for cucumb...
