稻田养用细绿萍,是增加产量,增肥改土的有效措施。稻田用萍,一般当季能增产稻谷一至二成;据我区测定,连续用萍五年,土壤能提高有机质0.3%。但是,要提高用萍实效,还应讲究科学养萍,合理用萍。如果用法不当,当季用萍,当季不一定见效。从试验和生产实践来看,要提高用萍效果,必须抓好如下技术关键。(一) 适宜的用萍量和方法在不同土质上的用萍
Fine green rice paddy cultivation, is an effective measure to increase production and increase soil fertility. Paddy field with Ping, the general season can increase rice 1-2%; according to my determination, continuous Ping five years, the soil can increase organic matter 0.3%. However, in order to improve the actual effect of using Ping, we should also pay attention to keeping science in a fair and reasonable manner. If you do not use properly, when the season with Ping, the season may not be effective. From the experiment and production practice point of view, to improve the Ping effect, we must grasp the following key technologies. (A) Appropriate Ping and methods used in different soil Ping
