丸化包衣对加工番茄种子发芽及成苗质量的影响

通过对加工番茄丸化种子进行培养皿发芽试验和穴盘直播育苗试验,调查发芽和成苗情况,结果表明:种子丸化后辅料的成分比例对丸化后的发芽有一定的影响,丸化组合中3号和4号辅料配比丸化组合对种子的发芽有促进作用,其发芽情况较为理想,可做为以后种子丸化的优选配比;直播成苗实验的结果虽然不太一致,但通过分析,认为可能是因为丸化利于种子的发芽、出苗,在相同的生长管理条件下出苗快也就意味着它比裸种有更多的时间生长,所以株高要高,茎粗要低些,根冠比要高,根的生长要长些,而在壮苗指数基本上差不多的情况下,丸化后的苗子比裸种的苗子表现更有优势。

Effects of Seed Pelletization on Germination and Seedling Quality of Processing Tomato Seed

The object of this study was to analyze experiments on processing tomato seed pelletized in the dish and seedling plug to investigate their germination.The results show that the proportion of coingredient content of pelletized seed of group No.3 and No.4 has facilitating effect on seed germination,which can be used as the dominant combination of pelletized seed.Although the result is not in the same level,after analyzing it could be known that the pelletization was helpful for seed germination and seedling emergence.If the living condition was in the same level,the pelletized seed would come out faster than naked seed,so they would have more time to grow,and that is why they are taller in height,slimer in stem diameter,higher in the root cap,and the root is longer.In the same seedling index,the pelletized seedling is beneficial to that of naked seed.
