种薯切块大小(本文称为种薯大度)对马铃薯产量有重要影响,在推广增产措施时也提出要‘切大块”,实践表明,马铃薯种薯切块小了产量固然不高,但如切块过大用种量激增也未必上算,因此,在我们的具体生产条件下,种薯切块究竟多大合适,这个问题就成为生产上必须考虑的问题。为此在77、78连续两年进行了种薯大度试验,为生产上制定高产栽培措施确定种薯切块大小提供依据。
The size of the seed potato diced (referred to herein as the seed size) has an important impact on the potato yield, in the promotion of measures to increase production also proposed to ’cut big chunks’, practice shows that potato seed production is small but not small, However, if the cut is too large with the surge in the amount may not be considered, so, in our specific conditions of production, how much is the appropriate size cut, this issue has become a production must consider the issue.To this end in the 77,78 For two years in a row, the potato seedling test was carried out to provide the basis for making high-yielding cultivation measures in production to determine the size of the seed potato diced block.
