四平市位于松辽平原中部,现有耕地面积约60万hm~2。主要作物为玉米,占耕地面积70％以上,有黄金玉米带之称,是全国重要商品粮基地。所辖的公主岭市和梨树县商品粮产量位居全国首列。四平市是一个严重缺水的地区,农业生产主要依靠自然降水,干旱是影响粮食生产的主要因素。为此,市、县两级农业、农机科研、推广部门积极研究、探索、试验多种抗旱节水方法,收到较好效果。目前主要推广6种机械化旱作节水耕种技术: 1.机械化深耕整地技术 秋季用深松、灭茬多功能耕作机整地,深松深度30～35cm,间隔60～65cm,或采用“双向深耕犁”翻地,深度25～27cm。翻后及时耙平镇压。梨树县农机推广站对此项技术进行的测定证明:采用深松、灭茬综合整地方法和双向犁深耕方法平
Siping City is located in the central Songliao Plain, the existing cultivated area of about 600000 hm ~ 2. The main crop is corn, accounting for more than 70% of arable land, known as the golden corn belt, which is an important commodity grain base in China. Under the jurisdiction of Gongzhuling City and Lishu County, the output of commercial grains ranks first in the country. Siping City is a severely water-scarce area where agricultural production mainly relies on natural precipitation. Drought is a major factor affecting food production. To this end, municipal and county levels of agriculture, agricultural research and promotion departments to actively explore, explore, test a variety of drought-resistant water-saving methods, received good results. At present, the main promotion of six mechanized dry farming water-saving cultivation techniques: 1. Mechanized deep plowing and soil preparation techniques Autumn subsoiling, stubble multi-purpose tillage machine preparation, deep pine depth 30 ~ 35cm, interval 60 ~ 65cm, or the use of " Turn to the ground, the depth of 25 ~ 27cm. Turned back after a timely repression. Lishu Agricultural Extension Station on the determination of this technology to prove: the use of deep pine, stubble integrated land preparation methods and two-way plowing
