杂交棉工厂化穴盘无土基质育苗移栽是河北棉花栽史上的第五次革命,第一次地膜、第二次化控,第三次机械化腹膜播种一体化,第四次品种改良,第五次杂交棉工厂化穴盘无土基质育苗,地膜腹盖增温保墒灭草,使植棉的植苗时间提前了10-15天,有效的延长了棉花的生育期,提高棉花的产量和品质,由于棉花播种时间提前了,加上机械化播种增加了棉种播量,农民见好苗舍不得拔,密度相应增大,出现了挤苗旺长,化控是解决旺长和生殖生长、营养生长协调生长的有效措施。机械
Hybrid cotton factory culture Plug Tray soilless seedling transplanting is the fifth revolution in Hebei cotton planting history, the first film, the second chemical control, the third mechanized peritoneal suture integration, the fourth species improvement, the first Five hybrid cotton factory plug tray soilless substrate nursery, plastic cover belly cover warming warmth and weed, cotton planting time advance 10-15 days, effectively extending the growth period of cotton and improve the yield and quality of cotton , Due to cotton sowing time ahead of schedule, coupled with mechanized planting increased the amount of cotton sowing, farmers see good seedling not pulling, a corresponding increase in density, there crowded Wang Wang long, chemical control is to deal with the growth and reproductive growth, vegetative growth Effective measures to coordinate growth. mechanical
