玉米栽培（Maize cultivation） Corn mechanization planting pattern of the source www.3 ed ??? In order to adapt to the continuous improvement of mechanization production level, through many years of experiments and research summed up corn mechanization planting mode, through three years of production on a large scale application proves that this mode, to adapt to the needs of the scale, corn intensive, industrial production development, is the key and core technology of the development of modern agriculture, improve the comprehensive grain production capacity in our city, economic benefits, social benefits and ecological benefits are very obvious. The mode of technology contents were introduced as follows:??? 1. moisture??? 1.1 fall subsoiling ridging??? For the autumn subsoiling ridge reached to broadcast state. Autumn soil preparation should be done during the proper tillage period. Namely: to achieve 40-60% of field capacity, soil moisture at the same time, soil is dry and white, kicking the ground clod fragile. Grab a layer of topsoil, 5-10cm soil, hand grip into a group, no water, hand without wet printing, landing scattered. The utility model adopts the combination of loosening, rotating, turning, raking, lifting and combining, and alternately creates the plough structure with the virtual and actual coexistence, so as to achieve the purposes of water storage, protection, extraction and drought resistance and flood. The straw, leaves in the field clean, use 210 horsepower tractor grand new Holland LZ360 type double combination and Dongfanghong 1804 tractor SQTN-420 combination of deep loosening, shallow harrow or shallow rotary tillage, ridging, fertilization, subsoiling depth 30-40cm, the depth of the error is about LCM, shallow shallow harrow rotary depth of not more than 5cm, deep stir, especially deep rotation, destruction of soil natural recovery ability, is not conducive to maintaining the stability of soil. Ridge distance 66.7cm, ridge flat La, the ridge distan
