Lodging-resistant organic slow-release fertilizer used for late rice planting and preparation method thereof

Abstract

The invention discloses a lodging-resistant organic slow-release fertilizer used for late rice planting. The fertilizer comprises the following raw materials: cassava dregs, bean pulp, cottonseed meal, peanut bran, radix sophorae flavescentis powder, coptidis rhizome powder, alga residues, humic acid, distillers' grains, plant ash, borax, calamine powder, ochre powder, coal ash, cobalt chloride, potassium chloride, ammonium chloride, ammonium hydrogen phosphate, ammonium nitrate, potassium sulfate, monopotassium phosphate, sodium silicate, a silicon-calcium fertilizer, calcium nitrate, calcium chloride, copper sulfate, ferrous sulfate, magnesium ammonium phosphate, ammonium phosphate, naphthylacetic acid, uniconazole, paclobutrazol, yeast powder, a straw fermentation inoculant, a rooting agent and a modified slow-release agent. The invention further provides a preparation method of the lodging-resistant organic slow-release fertilizer used for late rice planting. The prepared organic slow-release fertilizer used for late rice has excellent lodging resistance, and sufficient nutrition can be provided for all growing stages of the late rice.Therefore, the yield and the quality of the late rice can be improved.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a lodging-resistant organic slow-release fertilizer for late rice planting and its preparation method. Background technique [0002] There are many types of fertilizers currently used for late rice planting, and most of the special fertilizers for late rice are NPK compound fertilizers available on the market, which are mainly composed of three inorganic elements, N, P, and K, which can meet the growth needs of late rice in a short time. However, long-term use will damage the soil aggregate structure, easily cause soil compaction and soil hardening, thereby affecting the growth of late rice, making the stem and root system of late rice poorly developed, causing late rice to fall easily, and seriously affecting the yield and quality of late rice. Simultaneously, although pure organic fertilizer is rich in organic matter, it releases nutrients slowly, absorbs slowly in late r...

Problems solved by technology

However, long-term use will damage the soil aggregate structure, easily cause soil compaction and soil hardening, thereby affecting the growth of late rice, making the stem and root system of late rice poorly developed, causing late rice to fall easily, and seriously affecting the yield and quality of late rice. At the same time, although pure organic fertilizer is rich in organic matter, it releases nutrients slowly, absorbs slowly in late rice, and has low fertilizer efficiency. The effective balance of various effective nutrients cannot be achieved.
