涿鹿县是张家口地区坝下的一个山区县,境内北部的桑干河两岸,土壤较肥沃,灌溉条件较好,气候也较温和,雨热同季,无霜期140天左右,种一年一季作物有余。为了充分利用生长季节和自然资源,从七十年代开始搞间、套、复种的试验,逐步探索出春小麦、玉米带状种植形式,在河北省的塞外地带创出了不少高产典型。近年来,通过科技加投入,又发展成吨粮田栽培技术。1988年有5320.9亩粮田平均亩产1015.9公斤(小麦208.6公斤、玉米779.8公斤、豆类27.5公斤),获张家口地区吨粮田丰收计划二等奖。主要栽培技术如下: 一、采用合理的带型。采用5尺宽标准带型,其中小麦占3尺,种3行或4行,玉米占2尺,种2行,行距1尺。这种带型不仅小麦和玉米的边行多,边际效应大,而且彼此占地面积合理,有利高产潜力的发挥。
Zhuolu County, Zhangjiakou area is a mountainous area under the dam, the northern Sanggan River in the northern, more fertile soil, irrigation conditions are better, the climate is also mild, hot and rainy season, frost-free period of about 140 days, planting a year of crops More than In order to make full use of the growing season and natural resources, the experiment of engaging in intercropping, multiple cropping and multiple cropping started in the 1970s and gradually explored spring wheat and corn strip planting patterns. Many high-yielding typical patterns were found in the outlying areas of Hebei Province. In recent years, through technology and investment, but also developed into tons of grain cultivation techniques. In 1988, 5320.9 mu of grain fields averaged 1015.9 kilograms (208.6 kilograms of wheat, 779.8 kilograms of corn and 27.5 kilograms of beans), winning the second prize of the harvest project of ton grain fields in Zhangjiakou. The main cultivation techniques are as follows: First, the use of a reasonable belt type. The standard 5-foot belt type, which accounted for 3 feet of wheat, planted 3 or 4 lines, corn accounted for 2 feet, 2 lines, spacing 1 foot. This type of belt not only has more side lines of wheat and corn, but also has a large marginal effect and a reasonable area for each other to benefit from the potential of high yield.
