Abstract

Abstract Research was conducted at one location in 2003 and two locations in 2004 and 2005 to evaluate the effects of stand loss, planting date, and replanting method on flue-cured tobacco yield and quality. Stand loss treatments included a 10%, 20%, 30%, and 40% stand loss at two and four weeks after transplanting (WAT). In recent years, early season infections by Tomato spotted wilt virus (TSWV) have caused significant stand losses in North Carolina, so an additional treatment was included to simulate the effects of plant loss to tomato spotted wilt. Simulated losses consisted of a 10%, 10%, and 20% stand loss at 3, 4, and 5 weeks after transplanting, respectively. Planting date treatments included planting at the normal transplanting date and at 2, 3, 4, and 5 weeks after the normal transplanting date. To evaluate the effects of replanting method, tobacco was replanted at 2 or 4 weeks after normal replanting on an existing row ridge, a rebedded row ridge, and a tilled and rebedded row ridge. Due to exc...

林分损失、种植日期和复种方式对烤烟产量和品质的影响

摘要采用2003年1个试验点和2004年、2005年2个试验点，研究了林分损失、种植日期和再植方式对烤烟产量和品质的影响。在移植后2周和4周，林分损失处理包括10%、20%、30%和40%的林分损失。近年来，番茄斑病病毒(TSWV)的季前侵染在北卡罗来纳州造成了重大的林分损失，因此，采用额外的处理来模拟植株损失对番茄斑病的影响。模拟损失分别为移植后3周、4周和5周的10%、10%和20%的林分损失。定植日期处理包括定植日期和定植日期后2、3、4和5周的定植。为了评价复种方法的效果，在正常复种后的2或4周，在现有的行垄、重新垄作的行垄和耕作和重新垄作的行垄上重新种植烟草。由于……
