从1965年开始我们经过22年的试验,摸索出一套适合山东气候型抗旱种稻栽培制度,即三旱种稻法。内容包括旱育秧苗、旱整地和大田旱管理3个部分。具有省水、省工,省能源、降低成本,操作简便,并能防止直播田出现草荒与缺苗等优点,做到扬长避短,从而获得高产。目前本稻区稻、麦两熟大面积改为三旱种稻之后,麦茬稻平均亩产400公斤,高产地片达500～600公斤;稻茬小麦亩产250～350公斤。三旱种稻法是本稻区抗旱种稻,获得稻、麦两熟高择优配套的种稻方法。全区面积60万亩水稻,推广三旱种稻面积已达47万亩。其具体措施:(一)旱育秧苗一般旱秧田可以利用空间隙地,近年本稻区采用果园、菜园、场院、庭院、干涸池塘、
From the beginning of 1965, after 22 years of experiments, we have worked out a set of suitable rice cultivation systems for drought-resistant rice varieties in Shandong Province, namely the three dry-type rice cultivation methods. Including the nursery seedlings, dryland preparation and drought management three parts. It has the advantages of saving water, saving labor, saving energy, reducing cost, easy to operate, and preventing shortages of grass and lack of seedlings in the direct broadcast field, so as to achieve strengths and avoid weaknesses and achieve high yield. At present, the area of paddy rice and wheat is changed to a large area of three types of dry paddy rice. After that, the average stubble yield of wheat stubble rice is 400 kilograms and that of high-yielding loquat rice reaches 500-600 kilograms; that of rice stubble is 250-350 kilograms per mu. Three dry rice method is the paddy drought-resistant rice, access to rice, wheat and two high-supporting high-yielding method of planting rice. The area of 600000 acres of rice, promote the three dry rice area has reached 470000 acres. Its specific measures: (a) dry seedling seedlings generally dry seedling fields can make use of space, in recent years the use of orchards in this area, vegetable gardens, yard, courtyard, dry pond,
