Control of bud differentiation and the growing technique of urban and green tourism strawberry

为明确草莓花芽分化的环境条件，采用封闭式育苗系统对草莓幼苗进行培养。在8月9日至9月2日的光照、昼夜温度和CO_2浓度（分别为8h、25/15 ℃、1000 ppm）处理24天后，对幼苗的芽分化进行了研究。2月上旬（F）和3月上旬（M）在封闭式育苗系统中培养母株，光照16 h，昼夜温度25/15 ℃，CO_2浓度1000 ppm，诱导芽分化。结果表明：F、M处理诱导出的匍匐茎数分别为3.2和1.6，而在室外条件下则没有诱导出匍匐茎，封闭式育苗系统的环境控制对草莓幼苗的花芽分化和匍匐茎形成都是有效的。然后将幼苗种植在1.2m高的无土栽培通道中。这些栽培体系防止了病害的发生，提高了空间和时间的利用效率。同时，轮椅可以在这个修炼系统中移动。这样的都市农业系统将有助于无障碍绿色旅游的发展。

Strawberry seedlings were cultivated in closed seedling production system to make clear the environmental condition for induce flower bud differentiation. After 24 days treatment (August 9 to September 2)of day length, day/night temperatures and Co2 concentration (8h,25/15 C,1000ppm respectively), bud differentiation of the seedlings were investigated. On the other hand, bud differentiations were not investigated with the seedlings cultivated under outside condition.Mother plants were cultivated from early February (F) and early March (M) in closed seedling production system, with day length : 16h, day/night temperatures:25/15C and Co2 concentration:1000ppm, to induce runner formation. Numbers of runners induced were 3.2 under treatment F and 1.6 under treatment M, on the other hand there is no runner induced under outside condition.Environmental control under closed seedling production system is effective to induce for both of flower bud differentiations and runner formations of strawberry seedlings.Mother plants were cultivated on 1.5m height soil less culture channels to produce seedlings, and then seedlings were planted on 1.2m height soil less culture channels. These cultivation systems were prevented deceases and improved the space and time use efficiency. At the same time, wheelchair can move in this cultivation system. So, this system can be called one of the barrier-free systems.Urban agriculture system like this will be useful for barrier-free green tourism.
