水稻秧苗生长要求偏酸性的土壤环境,否则易发生青枯病和立枯病。近两年,我县推广使用敌克松,虽有一定效果,但仍不够理想。特别是在盘育苗的情况下,只用敌克松防治青枯病和立枯病,易使秧苗形成小老苗。为验证酸化床土、培育壮秧的效果,1986年我们在新沟乡搞了盘育苗酸化床土试验。 Growth of rice seedlings require acidic soil environment, or prone to bacterial wilt and blight. The past two years, my county to promote the use of enemy Kesong, although a certain effect, but still not ideal. Especially in the case of plate nursery, only the enemy Narcissus control bacterial wilt and blight, easy to seedlings to form small seedlings. In order to verify the acidified bed soil, nurturing the effect of strong seedlings, we engaged in the new ditch 1986 plate acidification nursery bed soil test.
