棉花“地膜两段育苗”是在覆盖地膜增温保墒条件下,通过加大方块早育壮苗和搬墩假植蹲苗促根两个阶段培育大壮苗。经过假植的大壮苗,根系发达,营养物质积累多,花芽分发早,抗逆性强。麦(油)后抢时移栽大壮苗,可以提高移栽成活率,缩短缓苗期,确保一次全苗,早发稳长,带桃入伏(早熟标志),获得早熟丰收。其技术要点如下:
Cotton “plastic film two sections nursery” is to cover the plastic film warming moisturizing conditions, by strengthening the box early nursery growth and pier pier dwelling seedlings promote root nurturing the two stages of big strong seedlings. After the fake planting seedlings, developed root system, accumulation of nutrients, flower bud early distribution, strong resistance. Wheat (oil) grab large transplanting seedlings, transplanting can improve the survival rate, shorten the hurried seedling stage, to ensure a full seedling, early onset of stability, with peach into the volley (early signs), access to early harvest. The technical points are as follows:
