我省种植红苕(甘薯)一般采用块根作种,用种量大,留种贮存容易腐烂,利用率低,成本高。为探索红苕新的留种途径,我们于1978年10月下旬,进行了苕鼻子贮存越冬和春后定植育苗试验。经试验结果,用苕鼻子育成的苕苗,其长势、扦插成活率均比块根育苗的好,增产也较显著。现就苕鼻子的贮存、定植育苗简介如下: The cultivation of red croaker (sweet potato) in our province is generally used as a seed, with a large amount of seed, leaving the kind of perishable storage, low utilization, high cost. In order to explore the new way to stay, we carried out the seedling nursery experiment in the late October, 1978 when the nose was stored for winter and spring. The test results, the bream nose bred nursery stock, its growth, cutting survival rate than root nursery, yield is also more significant. Now 苕 nose storage, planting seedlings Introduction is as follows:
