2.半促成栽培为自然地打破品种休眠,就必须经过该品种特定的低温需要量,如果低温过量后盖膜,会延迟收获期。所以应考虑采取强制地打破休眠,提早覆盖等方法。这就是把苗放入冷藏库内进行短期处理,不足部分用灯光补充,再覆盖寒冷纱和喷赤霉素。“达呐”的半促成栽培;打破“达呐”的休眠,需要5℃以下的低温约750小时,然后覆盖农膜。防止不合时令开花和低温为害是其栽培要点。为了防止不合时令开花,8月下旬后采苗,苗床施肥,以保证花芽的分化;为了保温,从12月上旬起覆盖农膜的同时盖寒冷纱,可多层膜,或者加温。“宝交早生”、“达呐”的植株冷藏栽培:这是把
2. Semi-promoting cultivation To naturally break the species dormancy, we must go through the specific needs of the variety of low temperature, if the low temperature over the cover film, will delay the harvest period. So should consider to force to break dormancy, early coverage and other methods. This is the seedlings into the cold storage for short-term treatment, the lack of supplements with light, then covered with cold yarn and gibberellin. Half-cultivation of “darna”; to break dormancy of “darna” requires a low temperature below 5 ° C for about 750 hours before covering with plastic sheeting. Prevention of out-of-season flowering and low temperature damage is the main point of its cultivation. In order to prevent irregular flowering, harvesting seedlings in late August, seedbed fertilization in order to ensure the differentiation of flower buds; in order to keep warm, from the beginning of December covering the agricultural film covered with cold yarn, multilayer film, or warming. “Bao Zao Zaosheng”, “Dan na” plant refrigerated cultivation: This is to put
