摘要
通过日光温室茄子敞穴施肥适宜用量的试验,可以看出敞穴施肥处理茄子产量随施肥量的增加而增加。从经济和环境综合考虑,日光温室茄子的敞穴施肥每666.7m2推荐用量以每次10~20 kg为宜。所测茄子样品的硝酸盐和亚硝酸盐含量,均远低于GB 18406.1-2001中瓜果类的允许标准,产品是安全的。
The uncovered-hole fertilization experiment was carried out to study the suitable fertilizer amount for eggplant in greenhouse.The results indicated that the eggplant yield increased with the increasing of fertilizer amount,and the suitable fertilizer amount was 10~20 kg per 666.7 m2 considering the economy and environment;the contents of nitrate and nitrite in eggplant were safely lower than the permission criterion of fruit in GB 18406.1-2001.
