一、试验目的和意义棉花营养钵育苗移栽,是促进棉花早熟高产的先进措施.但是投资较大,费工较多,又影响了大面积推广.一钵双株能有效的减少投资投工.但双株并生,又会出现生长不匀,一株大一株小,大苗欺小苗,小苗少结桃的弊病,不能很好地达到增产之目的,为了保证一钵双株均匀生长.近年来,我们对一钵双株栽培管理方法进行了研究,通过小面积试验,大面积示范证明,一钵双株既能节省投资、投工,降低成本,经过分棵压苗,又能控制疯长,保证稳长,实现棵低,枝密、节短、脱落少,结桃稠,高产优质的目的.
First, the purpose and significance of the test Cotton nutrition bowl seedling transplanting is to promote the cotton advanced precocity of advanced measures.But a larger investment, more labor, but also affected the large-scale promotion .A bowl of double strains can effectively reduce investment and construction. However, double strain coexistence, there will be uneven growth, a large plant small, seedlings bully seedlings, small seedlings less peach defects, can not achieve the purpose of increasing production, in order to ensure a uniform growth of double strains of a bowl. We have conducted a study on the management method of double crop cultivation in a single bowl. Through a small area test and a large area demonstration, we can save investment, work in progress and reduce costs through a large area demonstration. Ensure a stable, low, dense branches, short section, shed less, the conclusion of thick peach, high-yielding quality purposes.
