前言天津地区春季常干旱缺水,近年来郊区不少农民利用污水育秧,但由于經驗不足,灌溉管理不当,曾发生大量烂秧,造成毀种重播,延誤农时,早秧晚插,从而使种子及产量均遭損失。近年来生产实踐与科学研究証明,在天津市郊不同出水口,利用污水育秧,經过試驗均获得成功,这样,不仅可以充分利用污水解决育秧时水源不足問题,而且在清、污水具备地区,以污水代肥,解决了肥源問題,在生产上有其重要意义。
Preface Tianjin is often arid and dry in the spring. In recent years, many farmers in the suburbs use sewage to raise seedlings. However, due to lack of experience and improper irrigation management, a large number of rotten seedlings have occurred, causing the replanting of devastating species and delaying farming. And production have suffered losses. In recent years, production practice and scientific research have proved that, in different suburb outlets in Tianjin, the use of sewage watering seedlings has been successfully tested. In this way, not only can we make full use of sewage to solve the problem of insufficient water supply when raising seedlings, but also in areas with clear water and sewage, With sewage on behalf of the fertilizer to solve the problem of fertilizer, in the production of its important significance.
