下面的四篇资料都是选自《山东省农业科学实验成果选编》。我省花生生产中存在的问题与山东省大同小异,也是品种混杂退化,花生地土壤瘠薄,磷素营养不足,花生线虫病为害较重。山东省对这些问题通过科学实验都找到了比较好的解决办法,并在生产中收到了实效,值得我们很好学习。我省花生生产中还有一个重要问题就是多年重茬,病害严重,如果能象山东省一样利用当地的含磷风化土,大量铺施,不但能改良土壤,加厚土层,也能在一定程度上起到人工“造生茬”的作用。因此更应结合建设大寨田运动,发动群众,大量利用附近的含磷土资料,大搞磷土垫地。
The following four materials are selected from “Shandong Province Agricultural Science Experimental Results Selected.” Problems in peanut production in our province are similar to those in Shandong Province. They are also mixed and degenerated varieties. Soil in peanut is infertile. Phosphorus is undernourished and peanut nematodes are seriously harmed. Shandong Province has found a better solution to these problems through scientific experiments and has received practical results in production and deserves our good study. Another important problem in the peanut production in our province is that many years of continuous cropping have serious disease. If we can use the local phosphorus-containing weathered soil like Shandong Province and deploy it in large quantities, we will not only improve the soil and thicken the soil but also to a certain extent On the artificial “make stubble ” role. Therefore, more should be combined with the construction of Dazhai field movement, mobilize the masses, make extensive use of nearby phosphorus-bearing soil information, vigorously promote the phosphorus soil pad.
