席草具有无限分蘖习性,但不同环境条件下分蘖出生和生长速度差异悬殊,同时与席草产量、质量(草茎长度、粗度和枯梢等)密切相关。因此,探明分蘖出生和生长规律,对制订席草优质高产栽培技术具有一定的意义。 一、分蘖出生规律:席草在一个芽(最初母芽)长到3～5厘米长时,其下部叶腋里的新芽就突起,与母茎成45度夹角向上生长,并发育成母茎产生下一个芽。即以最初母茎→新芽(母茎)→新芽(母茎)……的方式增加,此为一次分蘖。以后每个一次分蘖第一个叶腋里也会产生腋芽,在环境条件适宜
The grass has infinite tillering habits, but there is great difference in the birth and growth rate of tillers under different environmental conditions, and is closely related to the yield and quality (grass length, coarseness, and wilt) of grass. Therefore, to determine the birth and growth of tillers, the development of high quality and high-yielding mat technology has a certain significance. First, the law of tiller birth: Mat in a bud (the first mother buds) grow to 3 to 5 cm long, the lower part of the axillary sprout in the bulge on the rise, and the stem angle of 45 degrees upward growth and development into stem yield Next bud. That is the first mother stem → sprout (mother stem) → sprout (stem) ... ... way to increase, this is a tillering. After each tiller in the first leaf axils will also produce axillary buds in the appropriate environmental conditions
