在淄博市的气候和土壤肥力条件下,从1987～1990年连续3年在水浇平原区开展了“10万亩吨粮田综合技术开发研究”,采用小麦、玉米一年二熟制的种植制度,组配了以改革种植规格为主要内容,以夏玉米增产为突破口的改、换、稀、密、配”5项吨粮田配套栽培技术,并大面积进行了实践与研究,均取得了明显的增产效果。我市地处山东省的中部。年平均气温在12.2～13.1℃,年降雨量575.6～679.0毫米,年日照2460.9～2813.5小时。粮田面积240万亩,其中旱涝保收面积占71.6％,小麦,玉米一年二熟制种植面积占86.7％,是全省有名的精种高产区之一。1987～1990年率先在全市水浇平原区开展了“10万亩吨粮田综合技术开发研究”课题,每年开发面积12.2521万亩,第一年度平均亩产973.7公斤,第二年度平均亩产1022.3公斤,第三年度平均亩产1060.4公斤,分别比开发前3年亩增204.9公斤,253.5公斤、291.6公斤。并于1989年在桓台县唐山镇建成了江北第一个吨粮镇,1990年在桓台县建成了我国北方第一个吨粮县,现将主要配套栽培技术与研究情况分述如下:
Under the conditions of climate and soil fertility in Zibo City, the “Research and Development on Integrated Technology of 100000 Mu Tons of Grain Fields” was carried out in the irrigated plain area for three consecutive years from 1987 to 1990. The planting of two crops of wheat and corn a year System, with the reform of planting specifications as the main content, to increase summer corn yield as a breakthrough in the change, change, dilute, dense, with “five tons of grain cultivation techniques, and a large area of practice and research were made A significant increase in yield effect.Our city is located in the central part of Shandong Province.Annual average temperature of 12.2 ~ 13.1 ℃, the annual rainfall of 575.6 ~ 679.0 mm, sunshine 2460.9 ~ 2813.5 hours. 240 acres of grain fields, of which Hanlaobaoshou area accounted for 71.6%, wheat, corn planted twice a year accounted for 86.7% of the area, is the province’s famous one of the high-yielding areas .1987 ~ 1990 took the lead in the city’s water plains area to carry out ”100000 mus of grain field synthesis Technology development and research "project, with an annual development area of 12.2521 mu, an average annual yield of 973.7 kilograms in the first year, 1022.3 kilograms in the second year and an average of 1060.4 kilograms in the third year, an increase of 204.9 kilograms over the previous three years of development , 253.5 kg, 29 1.6 kilograms. And in 1989 in Huantai County, Tangshan Zhenjiang built the first ton grain town in 1990 in Huantai County, built the first county in northern China tons of grain, now the main supporting cultivation techniques and research points Described below:
