    Chinese in recent years on the demand and development of agricultural machinery

    2014/7/29      view:

        China is a large agricultural country, each year more than 2500000000 acres of arable land, and multiple cropping index is higher, because the soil tillage workload is the largest in the farm work, so the soil tillage consumes a lot of energy. According to some reports, the power consumption of soil tillage accounted for agricultural powerSO%, therefore, to explore new farming machinery and farming methods, to reduce energy consumption, reduce labor intensity, improve work quality has always been aresearch topic of agricultural scientific research workers dedicated to research, but also for the development of the national economy is of great significance.

        On the other hand, in recent years with the development of agricultural mechanizationlevel in China, and the "three high" (high yield, high quality, high efficiency) of agriculture and the sustainable development of agriculture, fertilizer has attracted the attention of straw, stubble and other organic compounds. Widely used in large and medium-sized combine harvester, power and economic benefits based on the considerations, stubble height generally high combine harvester, general stubble is 15-20cm, high up to 30-40cm. For most of panicle type combine harvester, rice, wheat straw is the most in the field. A new request to stay the change trend of high stubbletillage is proposed for subsequent. Therefore, it is necessary to develop a new type tillage machinery to meet the above requirements. But the traditional tillage and rotary tillage can not fully meet the above requirements, Hua plough is used in order to cut soil over the fort, good performance, and can achieve deep, but the tilled soil was two times finishing with a rake, complicated operating procedures, low efficiency, high power consumption, high cost, and because the tractor many times into the ground,causing soil compaction, destroying the soil structure.

        The dual role of rotary cultivator harrow piece has cultivated and harrowing, thestubble, weeds, green manure crop cutting ability, not two times finishing, is conducive to saving time, so in the south area of China is widely used in the rotary tillage. The dual role of rotary cultivator harrow piece has cultivated and harrowing, the stubble,weeds, green manure crop cutting ability, not two times finishing, is conducive tosaving time, so in the south area of China is widely used in the rotary tillage. But theneed to power, poor coverage properties, stubble can not very good coverage, is not conducive to the decay of organic matter and fertilizer, and tilled weed initiated earlier.
