滩涂开发会遇到沟难保、苗难立、肥难追、夏难过的问题。1990年我们在开发滩涂过程中,探索出了四借四保克服四难的路子,第1年开发就取得显著成效,现将我们的做法总结如下。一、借草护沟保水系滩涂土质沙,沟系易倒塌。对此,我们采取了“借”草护沟、以柔克刚的办法。做法上一是抓合理坡比。凡是排碱沟(3.4米口面)以上的沟坡比定为1∶3,这样坡面大不易倒塌,并有利于茅草、芦柴向下串长,以草根固土,在植被增多后,沟系再逐年加深,缩小坡比;
Tide development will encounter ditch non-insurance, seedlings difficult to establish, fat hard to recover, summer sad problem. In 1990, during the development of the tidal flats, we explored the four cornerstones of “four borrows and four poods” and achieved remarkable results in the first year of development. We summarize our approach as follows. First, by grass protection ditch water beach muddy soil, ditch system easily collapsed. In this regard, we have adopted a “borrow” grass guard ditch, soft-g means. The last one is to grasp reasonable slope ratio. Where the ditch (3.4 m above the mouth) than the ratio of 1 to 3, so that the slope is not easy to collapse, and is conducive to thatch, Lu Chai downward string length to grass root soil, the increase in vegetation, Furrows and then deepen year by year, reducing slope ratio;
