Pelletizing agent for improving mechanical sowing performance of elymus nutans seeds

Abstract

The invention discloses a pelleting agent for improving mechanical sowing performance of elymus nutans seeds, which is prepared from the following components in parts by weight: 2 to 4 parts of ethylene glycol, 0.1 to 0.3 part of n-caprylic alcohol, 0.1 to 0.5 part of sodium benzoate, 10 to 20 parts of emulsion, 20 to 40 parts of talcum powder, 4 to 8 parts of carbendazim, 0.1 to 0.5 part of carboxymethyl cellulose sodium, 0.1 to 0.3 part of polyvinyl acetate and 25 to 35 parts of water. The preparation method comprises the following steps: selecting seeds, uniformly mixing the seeds to obtain a pelleting agent, screening, cleaning and disinfecting the seeds, pelleting the seeds by adopting the pelleting agent, and drying moisture in the pelleting agent in the sun to obtain the pelleted seeds, thereby being beneficial to solving the problems of mechanical seeding, incapability of precise seeding, low seeding seedling rate and high seeding cost.

Description

technical field [0001] The invention relates to the technical field of seed coating, in particular to a pelletizing agent for improving the mechanical sowing performance of E. Background technique [0002] Seed pelletizing is to make seeds with very small shape or rough outline, and wrap fillers and seed coating agents on the outside of the seeds through a pelletizing machine, and produce a certain hardness, Round or oval particles with smooth size and outline, to achieve large granulation of small seeds; [0003] Seed pelleting not only accomplishes the goal of plant protection before planting, and planting with fertilizers and medicines, but also promotes crop growth and seedling growth, thus providing a reference for agricultural mechanized production. The effect of increasing production; [0004] Although the grass seeds of Eucalyptus weedensis on the market have been cut off the awns, there are still short awns and rough surface of the seeds, which makes mechanical so...

AI Technical Summary

Problems solved by technology

[0004] Although the grass seeds of Elymus tachycarpa supplied in the market have been treated with broken awns, there are still factors such as short awns and rough surface of the seeds, which make it difficult to sow mechanically, and it is very easy to cause no seeding and uneven sowing. There are problems such as slow germination and low seedling retention rate, and the grass seeds are difficult to enter the soil due to the constraints of natural grass topography, slope, vegetation and other factors when reseeding, and the germination speed of seeds decreases under the condition of no covering soil.
