大蒜播种时鳞芽朝向对大蒜生长发育影响的试验研究(简报)

为了研究大蒜播种时鳞芽朝向对大蒜生长发育的影响,为研究大蒜播种机械提供参考依据,该文以徐州白蒜为供试品种,将鳞芽分为朝上、朝下和随机3种情况种植,观察大蒜生长发育情况.试验结果表明:播种时鳞芽朝下、朝上和随机时,大蒜均能顺利生长.但是,鳞芽朝下和随机时,发芽叶出土缓慢而且细弱,出苗期加长,出苗不整齐.在幼苗期,幼叶长大缓慢,露出土面较晚.大蒜植株较矮,叶面积小.蒜头重量轻,横径小.大蒜地下部分生长姿态与播种时鳞芽的姿态一致.鳞芽朝向随机和朝下时,蒜头在地下生长姿态呈倒立或平躺状.

Experimental study on effects of the bulbil direction on garlic growth

In order to study the effects of the bulbil direction on growth of garlic by experiment, the Xuzhou white garlic was planted. During seeding, the bulbil direction was designed as three directions: up, down and random. Results show that: in any direction, the garlic grows well, but the bulbil puts towards down and randomly, germinating foliage grows slowly and slimly, seeding stage becomes long, seeding was out of order, delicate foliage grows slowly, garlic grows slowly, the leaf area is small, the weight of garlic is light, and the diameter is small. The garlic guise underground was the same as the guise of bulbil during seeding. The bulbil puts towards down and randomly, the garlic guise underground was down and lay low.
