为了改变生产者在保护地蔬菜种植上施用化肥的盲目性、随意性和轻视有机肥的现象,解决因保护地土壤退化、养分比例失调而造成的土壤养分供应障碍,生理性病害普遍发生的问题,采用大田试验方法,于2005-2007年在连作番茄8年以上温室内,开展了生产上普遍应用的习惯施肥与全部用化肥、化肥+有机肥平衡施肥3种施肥方法对番茄的影响对比试验研究。结果表明,2种平衡施肥处理较习惯施肥,可显著改善植株生物学性状,减轻番茄生理性病害,改进番茄品质;极显著地提高番茄产量和效益,其中667m2分别增产27.5%和34.9%,分别增收4413.7和4872.1元;平衡施肥以化肥+有机肥在培肥地力,改善番茄品质,提高产量和经济、社会、生态等综合效益上更优更符合农业发展方向,值得在生产上推广应用。
In order to change the blindness, randomness and neglect of organic fertilizers by the producers on the vegetable planting in protected areas, solve the problem of nutrient supply of soil caused by the degeneration of soil and the imbalance of nutrients in protected areas, and the common occurrence of physiological diseases , Field experiments were conducted to compare the effects of three kinds of fertilization methods, including conventional fertilization and fertilizing with chemical fertilizers and organic fertilizers on the growth of tomato in a greenhouse with continuous cropping of tomato over eight years in 2005-2007 the study. The results showed that the two balanced fertilization treatments were more accustomed to fertilization, which could significantly improve the biological characters of the plants, alleviate the physiological diseases of tomato and improve the quality of tomato. The yield and benefit of tomato were significantly increased, of which 667m2 increased by 27.5% and 34.9% respectively Increase 4413.7 and 4872.1 yuan; balanced fertilization to fertilizer + organic fertilizer in fertility, improve tomato quality, increase production and economic, social, ecological and other comprehensive benefits better and more in line with the direction of agricultural development, it is worth promoting in production.
