| 摘 要： | 以普通尿素分次施用为对照,研究日光温室盆栽番茄一次性全量基施2种树脂包膜尿素对土壤理化特性及番茄生长的影响。结果表明,2种包膜尿素单施或混施,土壤NO- 3-N水平和土壤电导率均较稳定,具有促进根系吸水、协调植株生长作用,增产幅度5 .2 5 %～2 0 .80 %。

| Abstract: | With application of common urea 4 times contraot, the effects of two kinds of resin-coated urea on tomato applied one time were researched on the aspects of soil character and plant growth. The result showed that two kinds of resin-coated urea with single or mined application could maintain the stability of NO -_3-N concentration and electric conductivity in soil, promote root water absorption and plant growth harmony and enhance plant product by 5.25%-20.80%. |
