To the fertilizer knife determination of resistance

Abstract

Cotton fields are plowed in the fall, and the practice of removing cotton after the leveling process is becoming more common.In early spring, the temperature of the buds is higher than in the flat areas, which causes the frozen lumps to crumble, the soil to improve grain granularity, and the buds to be ready to suck early. Simultaneous fertilization with cotton yields increases cotton yields. Research in this area has shown that the method of spreading the fertilizer on both sides of the seed and in the middle of the base during the germination process has been studied.However, the method of layer application has not been studied. The article presents the results of research conducted to address this issue.In this case, a knife was installed in front of the pile receiver to break the soil along with the fertilizer spreader and make way for the fertilizer, and it was intended to apply the fertilizer in two layers of the pile, on the pile base and 12 ... 13 cm above it.To do this, the main drag resistance of the blade was determined using the condition that the remnants of weeds and debris were cut during movement and slid and pass under the blade. This indicates that the selected parameters of the blade are an important criterion for the effectiveness of the blade, which is the main factor influencing the performance and economic performance of the device. It is assumed that the total drag resistance of the fertilizer consists of three components, namely, the resistance to soil friction on the side surface of the blade, it was found that the concentration of 112 N - V = 2 m / s - is equal to 122.4 N.
