摘要
选取绿豆、芝麻、高粱等3种粒径为1～5 mm的种子,运用变容量型孔轮式排种器进行排种试验,分析排种均匀性、一致性、破损率等适应性参数,确定排种器对作物种子的适应性。结果表明:变容量型孔轮式排种器适用于芝麻、高粱的条播,不适应于绿豆的排种。通过正交试验分析转速、调节舌形式、调节舌宽度、播量调节档位对芝麻、高粱的排种均匀性、各行排量一致性和破损率的影响,当排种器的调节舌形式为圆头、调节舌宽度为8 mm、转速为50 r/min、播量调节档位为IV时,对提高芝麻、高粱的排种均匀性、各行排量一致性及降低破损率有利。
In order to study the adaptability of seed meter with variable capacity model-hole roller to different seeds,mung bean,sesame and sorghum in particle size of 1-5 mm were chosen in the test of seed metering to analyze the adaptation parameters including uniformity,consistency and breaking rate.The results showed that the seed meter with variable capacity model-hole roller is suitable for in drill sowing of sesame and sorghum,but not for seed metering of mung beans.Through the orthogonal test,the effect of the rotating speed,the form and the width of adjustable tongue and the gears for adjusting seeding rate on the uniformity,consistency and breaking rate of sesame and sorghum were analyzed,and the best combination of parameters was obtained.
