Embodiment 1

[0016] Turn on the coating machine, set the rotating speed to 4 gears, pour 3 kilograms of seeds into the coating pan, and add 100 milliliters of seed coating agent simultaneously, which contains 2% polyvinylpyrrolidone, 3% calcium dodecylbenzenesulfonate, Calcium carbonate 30%, dye 2%, azoxystrobin 2%, water 61%, after the machine rotates for 20 seconds, open the discharge hopper, and coat the seeds, vermiculite and water in a ratio of 1:2:2 by weight Mix well, place in airtight plastic bag, and place at 10°C for 48 hours. After the initiation, the vermiculite was removed from the seeds with a sieve, and the seeds were dried at room temperature for 24 hours, then dried in a 35°C drying oven until the water content was less than 8%, and then sealed for storage.

Embodiment 2

[0018] Turn on the coating machine, set the speed to 6 gears, pour 10 kg of seeds into the coating pot, and add 300 ml of seed coating agent at the same time, which contains 2% carboxymethyl cellulose, styrene acid polyoxyethylene polyoxyethylene Acrylic acid 2%, talcum powder 20%, dyestuff 2%, azoxystrobin 2%, imidacloprid 1%, microbial fertilizer 2%, water 69%, after the machine rotates for 20 seconds, open the discharge hopper, put the coated seeds and leech Stone and water are thoroughly mixed in a weight ratio of 1:2:2, placed in a closed container, and placed at 20°C for 36 hours. After the initiation, the vermiculite was removed from the seeds with a sieve, and the seeds were dried at room temperature for 24 hours and stored at low temperature for sowing.

[0019] Take out 400 seeds in each of the above examples for indoor germination experiment. The germination rate is measured according to the national standard. The emergence rate uses vegetable garden soil as the sub...

Abstract

The invention belongs to the technical field of seed processing and seed pelleting, and particularly relates to a method for processing ultra-sweet corn seeds. The method mainly comprises the following steps of: 1) the pelleting of the ultra-sweet corn seeds; 2) the priming of the ultra-sweet corn seeds; and 3) the drying of the ultra-sweet corn seeds. Compared with unprocessed seeds, the ultra-sweet corn seeds processed by the method germinate 1 day in advance, the rate of germination is improved by 10 percent, and compared with the control group, the sprouting percentage is improved by 10 percent after the seeds are dried and stored at room temperature for one year.

Description

technical field [0001] The invention relates to seed treatment and seed coating application technology, in particular to a super-sweet corn seed treatment method before sowing. Background technique [0002] The planting of super sweet corn has become more and more common in our country, but the vigor of super sweet corn seeds is weak, the emergence rate in the field is generally only about 50%, and the seeds are not resistant to storage, which has become the main obstacle restricting the development of super sweet corn, so how to improve super sweet corn The vigor of maize seeds, improving the rate of emergence and storage in the field have become an urgent problem to be solved. The genetic characteristics of super sweet corn itself is one of the reasons for its low vigor. The essential difference between super sweet corn and ordinary corn is that they carry a recessive mutation gene related to carbohydrate metabolism, which causes the seeds to shrink, not plump, easy to Br...
