上海郊区早稻育秧期间,往往低温阴雨,容易烂秧死苗。过去曾用抗菌剂402处理早稻种子,不仅具有良好的制菌效果,而且还能促进发芽和生长。但由于原料等原因,不能满足市场的需要。最近我们用“402”的同系化合物抗菌剂“301”进行早稻浸种试验,初步证明其作用优于抗菌剂“402”,可以作为早稻浸种消毒的药剂。一、试验概况供试品种早籼原丰早,先进行预备性试验,同“402”作比较,并以清水为对照。两种抗菌剂用1000、5000、10000倍三种浓度浸种72小时,随后用清水冲洗,置培养箱 During the early rice nursery in Shanghai’s suburbs, it is often cold and rainy and prone to rotten seedlings. In the past, the use of antimicrobial agent 402 to treat early rice seeds not only has a good bacteriostatic effect, but also promotes germination and growth. However, due to raw materials and other reasons, can not meet the needs of the market. Recently, we used the “402” homologous compound antibacterial agent “301” to test the soaking seeds of early rice. The results showed that the effect was better than the antibacterial agent “402”. First, the test profile Early indica Happo morning varieties, the first preliminary test, with “402” for comparison, and water as a control. Two kinds of antibacterial agent with 1000,5000,10000 times three kinds of seed soaking 72 hours, then rinse with water, set the incubator
