Slow-release compound fertilizer for cucumber

Abstract

The invention discloses a slow-release compound fertilizer for cucumber. The slow-release compound fertilizer comprises the following raw materials: 65-75wt% of a component A and 25-35wt% of a component B, wherein the component A comprises the following components in parts by weight: 30-40 parts of ammonium nitrate, 20-30 parts of cassava residue, 30-40 parts of soybean residue, 25-30 parts of cottonseed cakes, 15-20 parts of peanut shells, 15-25 parts of straw powder, 20-30 parts of bagasse residue, 20-25 parts of wheat bran, 10-15 parts of fishmeal, 5-8 parts of EM bacteria, 10-15 parts of sepiolite, 15-19 parts of bentonite, 10-13 parts of modified porous carbide and 10-15 parts of montmorillonoid and the component A comprises the following components in parts by weight: 40-50 parts of a slow-release urea iron fertilizer, 25-35 parts of calcium superphosphate, 15-20 parts of potassium dihydrogen phosphate, 20-30 parts of ammonium nitrate, 20-23 parts of potassium chloride, 15-18 parts of potassium sulfate, 3-6 parts of zinc sulfate, 2-5 parts of manganese sulfate, 8-12 parts of calcium humate, 1-4 parts of magnesium humate, 3-6 parts of sodium sulfate and 2-5 parts of boron humate.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a slow-release compound fertilizer for cucumbers. Background technique [0002] Cucumbers in the protected area grow for a long time, the environment temperature is high, and their root system is underdeveloped, and the absorption capacity of the root system is weakened in the later stage of growth. The existing fertilizer varieties in production cannot meet the requirements of cucumbers in a targeted manner. As a result, the fertilizer utilization rate is low, the soil salt accumulation is serious, and the disease increases, which affects the healthy development of vegetable production. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a slow-release compound fertilizer for cucumbers, whose release rate is equivalent to the absorption rate of nutrients in each stage of cucumbers, whi...
