1987年至1989年,安乡县连续3年进行了棉花营养钵泥浆穴施的试验、示范与推广,目的在于探讨解决棉花营养钵移栽后吊气死苗、缓苗期长的问题,以充分发挥营养钵育苗移栽的增产优势。全县3年累计应用面积12.3万亩,均收到了理想的效果。一是提高了移栽成活率,泥浆穴施移栽的死苗率为0.2％,而常规移栽的死苗率达30％;二是缩短缓苗期3-5天;三是提早生育期2-4天;四是提高单产,平均每亩增产皮棉6.0公斤,增产率为8.2％,除去成本,每亩增加纯收入31.2元。
From 1987 to 1989, Anxiang County experimented, demonstrated and popularized the mud hole application of cotton nutrition bowls for 3 consecutive years with the purpose of exploring the solution to the problem of hanging dead seedlings and slow seedling period after transplanting cotton nutrition bowl. Give full play to nutrition bowl transplanting seedling yield advantage. The county three years cumulative total area of 123000 mu, have received the desired effect. One is to improve the survival rate of transplanting, mud seedlings transplanting dead seedling rate of 0.2%, while the conventional transplanted dead seedlings rate of 30%; the second is to reduce the hibernation 3-5 days; the third is early growth period 2-4 days; Fourth, to increase yields, an average of 6.0 kg per mu yield lint cotton, yield 8.2%, to remove the cost, an increase of 31.2 yuan per mu net income.
