以开原紫皮蒜为试材对大蒜(Allium Sativum L.)生长发育基本规律进行剖析,试图为更有效应用于栽培技术提出科学依据,经试验结果表明:(1)苔的分化期先于瓣(鳞芽)的分化期。有时两者同时出现。分化前叶片生长量不仅对苔和瓣分化早晚有影响,而且对苔与瓣的生长量影响更大,所以促进叶面积增长是栽培前期的技术关键.(2)地膜应用不当,过高温与长光照对苔的的形成与发育很不利,会增多畸形苔和苔不能抽生出体外而减产,特别是抑制苦的居间生长.苔增长期避免过高温与长光照的不良影响是栽培中期特别要注意的问题.(3)生育后期,大蒜衰老部分营养物质向新生部分转输,进行再分配的生理变化,明显地表现出“源——库”关系的特点;促使“再分配”为“再利用”是栽培中、后期提高效益的依据。
The basic principle of growth and development of garlic (Allium Sativum L.) was analyzed with the original purple garlic as experimental material, trying to provide a scientific basis for more effective application in cultivation techniques. The experimental results showed that: (1) Petal (scale bud) differentiation period. Sometimes both appear at the same time. The growth of pre-differentiation leaves not only has an effect on the differentiation of moss and petals sooner or later, but also affects the growth of moss and petals more greatly. Therefore, it is the key technology to promote the growth of leaf area in the early stage of cultivation. (2) Light on the formation and development of the moss is very unfavorable, will increase the moss and moss can not increase the yield of moss and moss, especially to inhibit the intermediate growth of bitter moss growth period to avoid over-temperature and long-term light of the adverse effects of mid-planting special attention (3) In the later period of fertility, some nutrients of aging part of garlic are transferred to the newborn, and the physiological changes of redistribution obviously show the characteristics of “source-depot” relationship; Promote “redistribution” as “reuse ”It is the basis for cultivation and later improvement of efficiency.
