(一)、韭芽的根、茎叶都是变态的功能器管。根内含糖量最高,茎次之,叶较少。所以,生产上应着重培育根和鳞茎,才能获得丰产。(二)、保定红根韭通常于每年5月和10月出现孽芽原基,到8月和翌春4月发生分孽。每次平均分孽二个。每个分孽平均发生6.29条新根。其中春分孽根数较少,而2—3次根多。秋分孽根数较多,而次级根少。(三)、保定露地红根春韭于旬平均气温回升到5.86℃时开始生长。韭苗的生长速度于旬平均气温达5.9—14.4℃之间,随气温的上升而提高。于旬平均气温达14.4—20.5℃时,韭苗的生长速度无明显的变化。但根系的生长速度,则于旬平均地温7.1—26.6℃之间,随着地温的提高而显著加速。(四)、韭苗生长初期速度较快,共后渐慢,达到一定程度则停止生长。每个分孽只发生8—9片叶。露地红根春韭韭苗生长快时,根系生长慢;韭苗生长减缓时,根的生长转快。温室囤韭基本上无分孽和跳根表现。而且在室温经常保持在29.5—32.5℃的高温环境中,其生长速度并无显著的增加。(五)、露地春韭韭苗强则分孽旺,发根好,生长茁壮。而韭苗的强弱则受栽培、管理和收获的当否所支配。
(A), the root of leek buds, stems and leaves are abnormal function of the tube. Root sugar content of the highest, followed by the stem, leaves less. Therefore, the production should focus on nurturing roots and bulbs in order to obtain high yield. (B), Baoding Red Allium commonly occurs in May and October each year, the original base of evil buds, to August and the next spring in April, the occurrence of sub-sin. The average score of two each. An average of 6.29 new roots occur per division. Among them, the number of spring dividends is less, while the number of roots is more than 2-3. Autumn sub-root more, while less secondary roots. (C), Baoding open red root spring leek mean temperature rise to 5.86 ℃ began to grow. Leek seedlings growth rate at the end of the average temperature of 5.9-14.4 ℃ between, with the rise of temperature increased. When the average temperature reached 14.4-20.5 ℃, there was no obvious change in the growth rate of Leek. However, the root growth rate, at the average temperature of ten days between 26-26 ℃, with the ground temperature increased significantly accelerated. (D), early growth of leek seedlings faster, a total of slow, to a certain extent, stop growing. Only 8-9 leaves occur for each division. Exudation red root spring Allium leek seedlings grow rapidly, the root growth slow; leek seedling growth slowed down, the growth of the roots turn faster. Greenhouses store leek basically no division and jumping performance. And at room temperature is often maintained at 29.5-32.5 ℃ high temperature environment, the growth rate did not significantly increase. (E), open spring allium leek seedling strong sub-sub-Wang, hair roots, growth and prosperity. The strength of leek seedlings are cultivated, managed and harvested at the disposal of.
