有机肥和化学氮肥混合施用对番茄产量的影响

氮肥是植物生长过程中必不可少的一种肥料,一般植物特别是以叶和果实为产品器官的植物对氮肥的需要量很大,氮肥不足会限制植物的生长,影响植物的产量;但氮肥过多不但会影响植物贪青生长,影响植物的产量和产品的品质,还会造成环境污染,增加生产成本。试验采用对番茄进行化学氮肥和不同比例的有机肥混合施用的方法,以产量为指标,以确定在番茄生产上最好的氮肥施用方法。

Effect of Combined Use of Organic Fertilizer and Chemical Nitrogenous Fertilizer on the Yield of Tomato

Nitrogenous fertilizer is a necessary fertilizer to plant growth.Most plants need a large quantity of nitrogenous fertilizer.Shortage of nitrogenous fertilizer may prevent plant growing and affect its yield.However,too much nitrogenous fertilizer not only affects the quality and quantity,but also pollutes the environment and increases the cost.Taking the quantity as the index,the chemical nitrogenous fertilizer and organic nitrogenous fertilizer in suitable proportion were used together to determine the best way of using nitrogenous fertilizer on tomato.
