七十年代以来,我省水田大都实行机耕、机械旱耙,并结合使用518—12手扶拖拉机水平整地.由于旱耙能提早作业,因而解决了水耙作业时人畜力不足而延误农时的矛盾.旱耙还能减轻农机具磨损.但旱耙水平系列仍存在一般旱耙的缺点.为了节省能源,提高工效,保证水稻高产稳产的机械化稻田“耕整”体系,我们研究了以旋耕为主体的少耕法,并配套了机引驱动耙.旋耕的优越性有:1.从机耕作业方面分析:犁翻法在水田地区适耕期极短,据测定,犁耕适宜作业条件需在稻田撤水后地下水位回降到70厘米以下,土壤水分才能达到20
Since the seventies, most paddy fields in our province have practiced the mechanical tillage and mechanical dry rakes, and combined with the 518-12 walking tractor for horizontal leveling, which can solve the contradiction of lack of manpower and livestock and delayed agriculture during the operation of water rakes. Drought harrow can also reduce the wear and tear of agricultural machinery.But the series of dry harrows still have some shortcomings of common dry harrow.In order to save energy, improve work efficiency and ensure high and stable yield of mechanized rice “tillage” system, we studied the rotary tillage The main method of tillage and supporting the machine driven rake Rotary advantage: 1 from the tilling operation analysis: plowing law short period of adaptability in the paddy field, it is determined that plow suitable for working conditions Water level in the paddy field after the water table back to 70 cm below the soil moisture can reach 20
