自1962年平阳县城西公社缘萍(即满江红)越夏试验成功,引起了省内各地的重视。几年来的生产实践证明,连作晚稻田间养萍,的确是一条多快好省地解决晚稻缺肥和提高晚稻产量的有效途径。但目前在连作晚稻田间养萍技术方面,还缺乏比较完整的经验,特别是如何掌握放萍和“倒萍”适期以及如何提高连作晚稻田缘萍产量和进一步发挥其增产效果等问题,尚未得到很好的解决。为此,1964年我们在黄岩县路桥地区特对这些方面进行了一些试验,现将主要结果总结如下,以供参考。
Since 1962, Pingyang County West commune edge Ping (ie, Azolla) more successful summer test has aroused the attention of all parts of the province. Over the past few years of production practice has proved that even for the late rice paddy field, is indeed a more efficient and cost-effective way to solve the lack of late rice and improve late rice yield. However, at present, there is still a lack of more complete experience in the field of latecropping techniques for late rice. In particular, it is still unclear how to grasp the appropriate period of letting down and “down-pingping” and how to increase the yield of late-cropped Tianruiping and its yield increase further. Get a good solution. To this end, we in 1964 in Huangyan County Luqiao area especially on these aspects of some experiments, the main results are summarized below, for reference.
