本文研究了苍山大蒜在河南中部气候条件下不同播种时期对其生长发育及抽苔、分瓣的影响,找出了苍山大蒜在河南的适播期及晚播的危害。 1.苍山大蒜在河南以9月20—30日播种为好。早播时休眠尚未渡过,出苗较迟,晚播则造成减产。 2.晚播头重降低,瓣数减少,经回归分析,播期与头重的方程为:Y=57.259-3.159X;播期与瓣数的方程为:Y=8.76-0.411x。 3.大蒜的抽苔与分瓣关系密切。不分瓣的大蒜均不能抽苔,但不抽苔的蒜可能分瓣,而往往形成无苔少瓣蒜。 4.蒜头形成不仅要求较长日和较高温条件,而且要求有较大的营养体,晚播条件下,主要是影响了营养体的建成而影响了抽苔和分瓣,也影响了产量。
In this paper, we studied the effects of Cangshan Garlic on the growth, bolting and splitting of Cangshan Garlic in different seeding periods in central Henan under climatic conditions, and found the suitable sowing date and late sowing of Cangshan Garlic in Henan Province. 1. Cangshan garlic in Henan September 20-30 seeding as well. Early dormant yet to spend time sleeping, late emergence, delayed production is caused by the cut. The evening broadcast head weight decreased, the number of petals decreased, the regression analysis, sowing date and head weight equation: Y = 57.259-3.159X; sowing date and flap number equation is: Y = 8.76-0.411x. 3. Garlic bolting and the close relationship. Garlic can not be divided regardless of bolting, but not bolting of garlic may be sub-flap, and often form a small non-moss petal garlic. 4. Garlic formation requires not only longer days and higher temperature conditions, but also requires a larger vegetative body, late sowing conditions, mainly affecting the formation of vegetative and affect the bolting and sub-petal, but also affect the yield.
