国营黄泛区农场第四作业站,共有二十个区。由于区划不适当,地形非常复杂,增加了工作的困难。过去在播种时,如何根据地区的形状及机具的性质,探用适当的播种方法,从而节约油料,是缺乏缜密研究的。如在第三区播小麦时,纳齐拖拉机拉三台24行条播机,进行梭形播种法。由于地形不规则,工作起来很不方便,重播漏播的情况相当严重。同时,由于探用棱形播种法,廻蒋地区留得比较宽,行程系数仅在0.7左右,因而使生产率降低,耗油量增加。根据以往的经验教训,在播种之前,应当因地制宜,研究行走方法。对于不规则的地形,四周应留出同样宽的空地。在开始时插上标桿,使拖拉机直线行走,以免播种时发生‘弯套弯’的现象。纳齐拖拉机拉三台播种机在宽度较小,而长度在1000公尺以上的地区播种时,可采用梭形播种法,地头宽度为工作幅的四倍,两边空地为工作幅度的两倍。在宽度较大而长度在1000公尺以下的地区上播种时,司分为两个小区,采用套播法播种,四周均留出等于工作幅宽三倍的空地(如图)。所留出之空地,
State-owned Yellow Farm fourth farm station, a total of 20 districts. Due to the inappropriate zoning, the terrain is very complicated, which increases the difficulty of work. In the past, according to the shape of the area and the nature of the machinery used in sowing, the proper sowing methods were explored in order to save oil. Therefore, there was a lack of careful study. As in the third broadcast of wheat, Natche tractors pull three 24-reel seed drill, spindle cultivation method. Due to the irregular terrain, it is very inconvenient to work, and the situation of replay and missed broadcast is quite serious. In the meantime, due to the exploratory prism planting method, the Qiangjiang area remained relatively wide with a coefficient of travel of only about 0.7, resulting in a decrease in productivity and an increase in fuel consumption. According to past experience and lessons, before sowing, we should study ways of walking according to local conditions. For irregular terrain, the same width should be left around. Put a pole in the beginning to make the tractor walk in a straight line so as not to bend the curve when sowing. Natche tractors pull three seeders in the smaller width, while the length of more than 1,000 meters in the planting area, the spindle can be used seeding method, the width of the ground four times the working width, both sides of the airspace for the working amplitude of twice. When sowing in areas wider than 1,000 meters in length, the division is divided into two small plots, sowing and sowing, leaving an open space three times the width of the working envelope (pictured). The vacant space,
