一、试验经过1978年不育系繁殖秧田,选择在土壤肥力较好、水源方便、避风向阳的田块.冬耕冻土,春耕晒垡,春灌后又耕耙两次,施足底肥,开好水沟,做成合式秧田.基本上做到泥融、肥匀、田平、沟深、草净. 秧田按照净面积,父母本每亩均播种40斤.为了准确掌握播种量,播种时,量田称种,分墒定量,两次落谷,均匀播种.播种后,草灰盖种,搭架盖膜,力争做到齐苗、匀苗、壮苗. “育苗先育根,根旺苗壮”.其中关系最大的是水,我们采用“干墁湿润育秧”的科学用水方法,苗期湿润管理,秧
First, the test after breeding sterile lines in 1978, seedling selection of soil fertility is good, convenient water, shelter from the sunny field of winter tillage permafrost, spring plowing, spring rake and rake twice, Shi foot fertilizer, open Good ditches, made into a composite seedling. Basically mud melt, fat uniform, Tian Ping, ditch deep, grass net.According to the net area of seedlings, the parents of the sown 40 pounds per acre.In order to accurately grasp the sowing, sowing, Quantitative assessment of the amount of field, the amount of moisture points, two fall Valley, even sowing. After sowing, grass ash cover species, shelter cover film, and strive to Qi Miao, uniform seedlings, strong seedlings. Miao Zhuang. “One of the most relevant is the water, we use the” dry 墁 wet nursery seedlings, "the scientific method of water, seedling wet management, seedlings
