本试验主要是比较温室盘育带土中苗(简称温室中苗)、温室盘育无土中苗(简称无土中苗)、田间简易盘育带土中苗(简称简易中苗)、大田露地中苗(简称露地中苗)的一些生理性状,探讨田间简易盘育带土中苗机插高产的可能性及其高产的某些生理基础。材料和方法供试品种:早季“青二矮”,晚季“桂朝二号”。育秧方法:温室中苗是用有孔秧盘在温室培育至1.5片叶(一般7天),然后带盘移到大田培育直至插植;无土中苗是用无孔秧盘在温室培育到1.5片叶后,带盘移到室外营养池用营养液培育到中苗;简易中苗,是用有孔秧盘在大田露地育秧,即秧地经犁耙起畦,待秧畦泥沉实后,把与插秧机配套的有孔塑料秧盘整齐地排列在秧畦上,然后从畦沟取土于秧盘,床
The main purpose of this experiment is to compare the soil seedling (the seedling in the greenhouse), the soilless seedling in the greenhouse (referred to as soilless seedling), the soil seedling (simple seedling) in the field, In the field of seedlings (referred to as open field seedlings) of some physiological traits, to discuss the field of a simple plateau soil Miao machine inserted the possibility of high yield and some of its physiological basis for high yield. MATERIALS AND METHODS Varieties for testing: Early Qing dwarf, late season Gui Cha II. Nursery method: the greenhouse seedlings are grown with holes in the greenhouse tray to 1.5 leaves (usually 7 days), and then reel to the field until planting; soilless seedlings are non-porous seedlings cultivated in the greenhouse to 1.5 leaves, the reel moved to the outdoor nutrition pool with nutrient solution to nurture seedlings; simple seedlings, is the hole seedling tray in the open field nursery, that seedling rake razor, until seedlings mud sink After the transplanter with a matching hole plastic plastic seedlings neatly arranged in the seedlings on the Yang, and then from the ditch ditch soil in the tray, bed
