The invention discloses a seed
fertilizer suitable for simultaneous
sowing of cotton seed
fertilizer and a preparation method and application, the seed
fertilizer is composed of
urea,
ammonium polyphosphate,
potassium sulfate,
ammonium heptamolybdate,
ethylenediamine ferric o-dihydroxyacetate, biostimulant and
polyacrylamide, and the preparation method comprises the following steps: fully mixing the raw materials in batches by using a three-dimensional mixer, weighing and sub-packaging to obtain the seed fertilizer. The problem of accelerated
moisture absorption caused by direct contact of
urea easy to absorb
moisture, mineral source
potassium fulvate and
polyacrylamide is effectively avoided;
potassium sulfate is added,
absorption of water vapor is effectively prevented, so that no
moisture-proof agent is added, the added
polyacrylamide has a
water retention function, and seed fertilizer is applied into soil and cotton seeds are sown into the soil at the same time by utilizing a cotton seed fertilizer simultaneous
sowing machine; according to the seed fertilizer formula and the application method, the problems of serious soil-borne diseases, insufficient soil fertilizer supply capability, insufficient development, poor resistance and the like in the cotton
seedling stage can be solved, and the problems of cotton yield reduction and
fiber quality reduction caused by the problems can be solved.
