以分蘖洋葱杂交种‘珠葱1号’为试材,进行了分蘖洋葱杂种一代鳞茎分割栽培试验,以不切割处理的分蘖洋葱和阿城农家品种‘紫皮分蘖洋葱’为对照,确定鳞茎的最佳繁殖系数,旨在更加经济有效地利用分蘖洋葱杂种一代鳞茎。结果表明:种用鳞茎不分割处理,出苗率、生长势、抗病性和产量等指标表现最好,但单位面积种用鳞茎成本最高,约占单位面积产值的50%;鳞茎6等分和8等分处理繁殖系数高,但出苗率降低,生长势弱,产量过低;与不分割处理相比,鳞茎2等分和4等分处理出苗、生长、产量等指标降低不明显,而且种子成本大幅下降,单位面积产值较高。综合用种成本、鳞茎质量和产量、效益等指标,鳞茎2等分和4等分处理既降低了用种费用,又达到了增产增效目的。
A trial was conducted on the bulb-cutting cultivation of tillering onion hybrids with the tillering onion hybrid ’Beizhudou No.1’ as test material. The control of tillering onion and Acheng peasant cultivated ’Purple-skinned tiller onion’ The optimal breeding coefficient is designed to make more efficient use of the tillering onion hybrids bulbs. The results showed that: the seedlings with the bulb without division, the emergence rate, growth potential, disease resistance and yield indicators such as the best performance, but the highest cost per unit area with the bulb, accounting for 50% of the unit area output; bulb 6 and 8 treatments had higher propagation coefficient, but the emergence rate was lower, the growth potential was weak and the yield was too low. Compared with the non-dividing treatment, the seedling emergence, growth and yield were not obvious, Significantly reduce costs, high output value per unit area. Comprehensive use of cost, quality and yield of bulbs, benefits and other indicators, the bulb 2 and 4 equally divided treatment reduces the cost of species, but also achieved the purpose of increasing production and efficiency.
