The invention relates to the technical field of
plant seed treatment and cultivation, and discloses a preparation method of
portulaca oleracea pelletized seeds with improved
stress resistance, which comprises the following steps: S1, providing
portulaca oleracea seeds, putting the
portulaca oleracea seeds in a
coating machine, and adding clear water until the surfaces of the seeds are wet to achieve a state that the seeds are clustered by hand pinching and are scattered by touching; s2, a
coating machine is started, and a filler composition containing talcum
powder, kaolin and
bentonite is added in the running state. According to the preparation method, by optimizing a filler and
adhesive system, purslane seeds are prepared into
pellets with the uniform particle size and the
smooth surface, the weight and the size of the seeds are increased, mechanical precision seeding is achieved, and a foundation is laid for large-scale planting; meanwhile, seed microenvironment can be adjusted,
saline-alkali stress can be buffered, seed
germination potential and
germination rate are remarkably improved,
stress resistance is enhanced, and
saline-
alkali soil planting potential is expanded; according to the scheme, the traditional empirical defects are overcome, the
repeatability is high, and reliable
technical support is provided for industrial application.
