麦田套种花生,是多年来花生产区农民经济利用土地、提高复种指数和单位面积产量、解决粮、油争地的矛盾而采用的一项有效措施。但过去套种的时间较晚.是在小麦开花灌浆阶段,这时正是小麦需水最多的时期,若是雨水不足,往往不能进行套种,或者套种之后种子落干而造成缺苗减产。另一方面,在这时套种大花生还不能充分满足其生育的要求,比春播花生減产很多。因此,限制了套种花生面积的进一步扩大。近几年来,本省不少地区如文登、荣成、蓬莱、海阳、福山、莒 Wheat field intercropping peanut is an effective measure adopted by peasants in the peanut production area over the years for economic use of land, improvement of crop yield and production per unit area, and resolution of conflicts over grain and oil. However, in the past, the earlier intercropping was done in the stage of flowering and filling of wheat, which is the period when wheat needs the most water. If the rainwater is insufficient, it is often impossible to intervene or the seedling is reduced after intercropping. On the other hand, interplantation of large peanuts at this time can not fully meet the requirements of their reproductive, peanut production than spring sown a lot. Therefore, further expansion of interplanted peanut area is limited. In recent years, many parts of the province, such as Wendeng, Rongcheng, Penglai, Haiyang, Fukuyama, 莒
