摘要
试验证明:在相同栽培条件下,同一种的南繁种子较北繁种子产量和含糖率都有提高,其中平均含糖率提高0.55%,块根产量增加5.73%,产糖量增加9.5%,在目前生产条件下,同一品种南繁种子较北种子每亩增加产糖量15.(?)公斤,增加收益为19.49元.
The test shows that under the same cultivative condition and varietythe beet yield and sugar content using over-wintering beet seeds in southof China is higher than that reproducing in north of China.And averagesugar content is increased by 0.55%,The root yield is increased by 5.73%.The sugar yield is increased by 9.5%.Under present productive conditionthe sugar yield can be increased by 15.2 kg/mu and the income can beincreased by 19.49 yuan/mu.
