在土壤肥力较高、有灌溉条件的耕地上,实行深根型与浅根型作物、喜光性与耐荫性作物多层次的间、套、复种,充分利用土体和上部空间的光热资源,是增加产量,提高经济效益的有效措施。在种植过程中,必须相应地增加投工、投资,提高上壤肥力;同时,技术要从严要求,从茬口安排、间套复种方式、品种布局、田间管理、收获贮藏等方面都要“配套成龙”,做到种上季看下季,统筹兼顾,才能充分发挥间、套、复种的优势。乳山县位于山东省胶东半岛东南部,是粮油作物主要产区之一。近几年来,在保证粮食生产的前提下,积极推广应用了
Under the conditions of high soil fertility and irrigated land, deep-rooted and shallow-rooted crops, multi-level interplanting, multiplication and multiple cropping of hi-light and shade-tolerant crops should be implemented to make full use of the light and heat resources in the soil and the upper space, Is to increase production, improve economic efficiency of the effective measures. In the process of planting, it is necessary to increase the investment and increase the fertility of the soil correspondingly. At the same time, the technology should be strict with the requirements of crop arrangement, intercropping, crop arrangement, field management, harvest storage, etc. In order to make full use of the advantages of intercropping, multiplication and multiplication, Rushan County is located in the southeast of Shandong Peninsula, Shandong Province, is one of the main producing areas of grain and oil crops. In recent years, under the premise of ensuring food production, the project has been actively promoted and applied
