甜菜纸筒育苗移栽技术的示范推广工作已在海伦县进行了两年。1982和1983年的高产田,分别达到每亩3.33—3.67吨的产量。它的主要优点是:可以延长甜菜营养生长日数30—45天,增加积温300—500℃;移栽的甜菜苗令长、植株大、对病虫害的抵抗力也强,有利于保苗;育苗移栽能增加单位面积内株数,建立合理的群体结构。采取育苗移栽,一般可提高单产30％左右。因此,在气候土壤适宜、技术力量和整地机械条件具备的地区,可以推广该项栽培技术。现将主要育苗移栽技术介绍如下。
Beetle tube seedling transplanting technology demonstration and extension work has been carried out in Helen County for two years. The high-yield fields in 1982 and 1983 reached yields of 3.33-3.67 tons per mu, respectively. Its main advantages are: can extend the number of beet vegetative growth days 30-45 days, increase the accumulated temperature 300-500 ℃; transplanted beet seedling make long, plant large, strong resistance to pests and diseases, is conducive to seedlings; seedling transplanting energy Increase the number of plants per unit area, establish a reasonable group structure. Take seedling transplanting, generally can improve yield about 30%. Therefore, the cultivation technology can be popularized in areas where climate and soil are suitable, technical force and soil preparation machinery are available. Now the main seedling transplanting techniques are as follows.
