After seed processing, the grains are full, uniform in size, the crops grow neatly, and the maturation period is the same, which is conducive to mechanized sowing and harvesting, and increases the labor efficiency. The calculation of seed plumpness is calculated using 1000-grain weight, and the measurement process for 1000-grain weight is generally used. It will use a seed counting instrument and a balance of different precision (the difference in seed particle size, the weight accuracy of a thousand-grain weight is different). The determination of the seed germination rate is mainly carried out by using the seed germination box, which is in full compliance with the requirements of the seed germination environment.
Seed processing techniques were first proposed by Americans in 1926 when they proposed seed coating. Then in the 1930s, the British company successfully developed a seed coating agent, which is a further layer of seed treatment technology. By 1941, the United States used mechanically seeded seeds for mechanical seeding. At this time, it also paid more attention to the clarity of seeds. In the 60s of the last century, European attention to seeds was quickly commercialized, and the requirements for quality of seeds for commercialization were limited. In the following decades, the problem of technical treatment of seeds was increasing day by day. However, the treatment of seed technology in our country was the real beginning in the late 1950s.
The goal and history of seed processing technology
The objective of seed treatment technology and its historical seed as a most basic, irreplaceable and vital agricultural production data have an important role in agricultural production. After the seed is harvested, a series of treatments are carried out to change the physical characteristics of the seeds to improve and improve the seed quality, and to obtain a commercial seed with high clarity, high germination rate, high purity, and high vitality. After the processing, the accuracy of the seeds is the highest. At least 2%-3% can be increased and the germination rate is increased by 5%-10%. In order to improve the use of seeds and improve the health of seedlings and survival.
