Embodiment 1

[0028] The white clover seed pelletized coating method adopts the following schemes to realize:

[0029] 1. White clover seed treatment

[0030] Before the white clover seeds are pelletized and coated, certain treatments must be carried out to ensure the cleanliness, purity and uniformity of the seeds.

[0031] Winning: natural winnowing or mechanical winnowing can be used to remove impurities, dust and unfulfilled seeds.

[0032] Screening: According to the size of the seeds, select different sieves to remove the seeds that are too large or too small to ensure the uniformity of the seeds. Generally, a 20-mesh sieve is used to sieve the small grains and small impurities; a 10-mesh sieve is used to sieve the oversized grains and impurities.

[0033] 2. Preparation of coating agent: prepare 100Kg of coating agent through the process of the above-mentioned processing of Clover seed (bare species), and coating agent comprises A-type coating agent, B-type coating agent, C-type co...

Abstract

The invention relates to a pelleting coating method for Trifolium repens seeds and creates conditions for mechanization of grassland construction by carrying out pill coating on the Trifolium repens seeds. The method comprises the following steps: (1) processing of the Trifolium repens seeds: prior to the pill coating, the Trifolium repens seeds are processed by air separation and screening; (2) preparation of a coating agent: the coating agent comprises an A type coating agent, a B type coating agent, a C type coating agent, adhesive and nutrient fluid; (3) process of pill coating of the Trifolium repens seeds: the Trifolium repens seeds processed by the procedures are put in a coating machine, the external surfaces of the seeds are covered with the adhesive evenly, and the A type coating agent is added; then, the B type coating agent is added, and simultaneously liquid jetted by a flow feeder is changed into the nutrient fluid; liquid jetting is carried out continuously, and coating powder is added for pelleting; after the B type coating agent is added, the adhesive and the C type coating agent are added; and after being taken out, the seeds are insolated or dried in time, and after the insolation or drying, the coated seeds are packaged by fiber drums.

Description

technical field [0001] What the present invention relates to is a kind of pelletized coating method of white clover seed, implements pelletized coating to white clover seed, establishes the formula of pelletized coating agent, coating process, effectively and domestic coating equipment Matching use can solve the problems of uneven seed coating and brittle coating in the production process, ensure the quality of white clover coated seeds, and promote the rapid improvement of white clover seed coating technology. Mechanization created the conditions. Background technique [0002] White clover Ttifolium repens L, alias: white clover, scientific name: Ttifolium repens L. The thousand-grain weight is 0.5-0.7 grams. White clover is native to Europe and was first cultivated in Holland in the late 16th century. It is now distributed in temperate regions of the world. In 1957, the cultivated area in the United States reached 45 million mu. It is planted in Hubei, Hunan, Zhejiang, ...
