Problems solved by technology

However, for the re-seeding of native grass species on the Qinghai-Tibet Plateau, the effect of re-seeding with naked seeds is often not good
Due to the harm of subterranean pests, pikas and zokors to re-seeding grassland, the effect of re-seeding naked seeds is not good, and they are often eaten by birds or the roots of plants are eaten by zokors
In addition, due to the harsh environmental conditions, the growth of newborn seedlings is weak, and it is difficult to form dominant species on the grassland, so it is not conducive to the establishment of turf

preparation example Construction

[0044] The embodiment of the present invention also provides a method for preparing coated seeds, which uses the above-mentioned seed coating agent to coat the seeds to prepare coated seeds.

[0045] In some embodiments, other components other than talc powder are firstly mixed to form a coating solution, the seeds are wetted in contact with the coating solution, and then fillers are added, so that the fillers can coat the seeds. In the actual operation process, the coating of the seeds is carried out in the coating machine, including: first put the seeds into the coating machine and idle for 5-15s to remove the dust in the seeds, add the coating solution into the coating machine to make the seeds Wet in contact with the coating solution, and then add talcum powder into the coating machine for seed coating, so that the talcum powder can fully coat the seeds.

[0046] In some embodiments, the preparation method further includes drying the coated seeds in a cool place.

Abstract

The invention discloses a seed coating agent, coated seeds and a preparation method and application thereof, and relates to the technical field of agriculture. According to a seed coating agent, microelement fertilizer and ammonium bicarbonate are used as fertilizers, chlormequat chloride and brassinolide are used as plant growth regulators, styrene-acrylic emulsion and sodium carboxymethyl cellulose are used as fixatives, trichoderma harzianum, a nutrient medium, a water-retaining agent, a film-forming agent, an anti-freezing agent, a filling agent and a chelating agent are matched, and the stress resistance of plants can be remarkably improved through a comprehensive formula; the seed coating agent has the advantages of promoting seedling growth and increasing yield, and the prepared coated seeds are particularly suitable for reseeding operation of degraded grassland in the Qinghai-Tibet Plateau area.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a seed coating agent, coated seeds and a preparation method and application thereof. Background technique [0002] Seed coating is a seed treatment technology commonly used in many areas. It uses seeds as carriers, seed coating agents as raw materials, and coating machines as means. It is a comprehensive seed treatment technology that integrates multiple achievements in biology, chemistry, and machinery. Since the 1980s, my country's seed coating agent has been successfully demonstrated and widely promoted. It can not only prevent pests and diseases, but also promote plant growth, and has the functions of significantly increasing production and income. [0003] At present, my country's seed coating technology is mainly applied to field crops, such as wheat, corn, cotton, soybean, rice and other grain economic crops. The development of grass seed coating technology is relati...
