我国南方双季稻产区在春季早稻育秧期间,常受低温多雨天气的危害而发生烂秧,对早稻生产的影响甚大。中国科学院化学所和山西农业大学都做过试验,证明河南黄腐酸和山西硝基腐植酸溶液对水稻浸种,有促进秧苗发根的作用。为探求现已有售的河南和山西的腐植酸商品,是否可用于我省早稻育秧,以达到提高秧苗素质,防止烂秧的目的。1989年春,在富阳县新浦乡港东村进行了本试验。现报道如下:
During the early rice growing season in spring, the double-cropping paddy producing areas in southern China often suffer from rotting seedlings under the impact of cold and rainy weather, which has a great impact on the production of early rice. Chemical Institute of Chinese Academy of Sciences and Shanxi Agricultural University have done tests to prove that humic acid and Henan Henan humic acid humic acid solution of rice seed soaking, to promote seedling roots. To explore the now available Henan and Shanxi humic acid products, can be used for early rice cultivation in our province, in order to improve the quality of seedlings to prevent rotting seedling purposes. In the spring of 1989, this experiment was conducted in Gangdong Village, Xinpu Township, Fuyang County. Reported as follows now:
