A special liquid fertilization for potatoes and its preparation method

Abstract

The invention discloses a special liquid fertilization for potatoes, which is characterized in that the fertilizer is made of the following raw materials in parts by weight: 100 parts of fresh chicken manure raw liquid fermentation liquid, 8-10 parts of urea, and 1.5-2 parts of potassium dihydrogen phosphate , 5-8 parts of potassium humate, 0.01-0.03 parts of ammonium molybdate, 2-5 parts of boric acid, 3-7 parts of ferrous sulfate, 3-6 parts of magnesium sulfate, 2-5 parts of zinc sulfate, 8-10 parts of compound acid 1-3 parts of water-retaining agent, 5-10 parts of diammonium, 20-35 parts of potato extract, 15-20 parts of chitosan, 5-10 parts of alginic acid, 3-5 parts of soybean extract, 0.2 parts of bulking agent ~0.5 parts, plant ash water 10~12 parts, vegetable leaf fermentation liquid 40~60 parts. The fertilizer uses chicken manure and waste vegetable leaf fermentation liquid as the main organic matter, which is comprehensive and rich in nutrition, and these two organic matter are low-cost waste, which can be used in this fertilizer to turn waste into treasure and play a role in protecting the environment , with good social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of liquid fertilizers, and in particular relates to a special liquid fertilization for potatoes and a preparation method. Background technique [0002] Flush fertilization is a multi-component compound water-soluble fertilizer, which can quickly dissolve in water, be more easily absorbed by crops, and have a relatively high absorption and utilization rate. More importantly, it can be applied to facility agriculture such as sprinkler irrigation, realize the integration of water and fertilizer, and achieve the efficiency of saving water, fertilizer, labor and increasing production. In addition, flushing fertilization has the advantages of safe, uniform, and convenient fertilization. It can not only avoid damage to the root system of crops by fertilization by ditching, but also avoid damage to delicate stems and leaves by spreading chemical fertilizers. caused by root burn. It is suitable for crop cultivation...
