Environmentally-friendly water-saving water-holding fertilizer and preparation method thereof

Abstract

The invention discloses an environmentally-friendly water-saving water-holding fertilizer and a preparation method thereof. The environmentally-friendly water-saving water-holding fertilizer comprises the following raw materials in percentage by weight: 5-15% of diatomite, 5-15% of urea, 5-30% of lignite, 20-35% of bentonite and 30-45% of volcano basalt zeolite. The preparation method of the environmentally-friendly water-saving water-holding fertilizer comprises the following steps of: step 1: separately crushing diatomite, urea, lignite, bentonite and volcano basalt zeolite, drying to water content of 5-10% and screening by 180-200 mesh; step 2: stirring for mixing diatomite, urea, lignite, bentonite and volcano basalt zeolite powders acquired in step 1 for 30 minutes; and step 3: adding the diatomite, urea, lignite, bentonite and volcano basalt zeolite powder mixture acquired in step 2 to a fermenting tank, adding microorganism Bacillus subtilis fermenting agent 1% of total weight, mixing and stirring for 15 minutes and naturally fermenting for 5-10 days. The invention has the advantages of simple preparation method, low cost, no pollution of a product, high fertilizer effect and good water-holding and water-saving effects, and is convenient to use,.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to an environment-friendly, water-saving and water-retaining fertilizer and a preparation method thereof. Background technique [0002] In recent years, with global warming, my country's annual average temperature has risen, regional precipitation and river runoff fluctuations have increased significantly, extreme weather and climate events have increased and intensified, and drought disasters have shown an intensified trend. Expanding to cities and ecological environments, the area of ​​drought has also expanded from the west and north to the east and south. In the grain-producing areas of the North China Plain, due to the perennial overexploitation of groundwater, a large number of underground funnel areas have appeared. Therefore, the development of rural water conservancy and water conservation and water-saving agriculture Technology is an urgent need for my country's sustainable agri...

Problems solved by technology

However, most of the agricultural water-retaining agents used in the market are made of chemical materials, the production cost and use cost are relatively high, and the operation is relatively complicated when used, and it will cause damage to the soil after long-term use, which is not conducive to environmental protection. These all need to be improved
