Chromatic plastic film and light conversion film has been applied in protected cultivation, and plastic films with different light quality may serve as a non-chemical approach regulating growth and thermoperiodic responses of plants. A few studies showed that light quality affected growth and yield of strawberry, but little is known about its effects on photosynthesis and chlorophyll fluorescence in strawberry leaves, and fruit quality. So it is beneficial to scientific regulating growth and fruiting for strawberry protected cultivation to study on those effects and the interactions between CO2 and N supply on photosynthesis.

而低氮影响植株生长、叶片黄化，进而影响光合作用，导致抗性减弱和产量品质下降；③CO_2供应问题：目前我国草莓栽培常在设施环境下进行，在封闭性强的设施中空气流通不畅，常导致设施内部CO_2供应不足而影响光合作用，进而影响产量和品质；④光不足与光质问题：设施栽培中，光通过玻璃和塑料棚膜后使设施内的光强与光质均发生改变，这些变化特别是光质变化对草莓生长与结果的影响程度尚无明确认识。

The price pricking beer is 3 5 times higher than familiar equal amounts beer , investigates whose cause to have several aspect down: One, has been fresh beer because of it , has kept fine taste of beer and nutrition; That sterile condition demands is strict among it's two , procedure of production, equipment investment is big, be going to want the strict sterility course film fliteration or hole fliteration, besides all microorganism , beer barrel and production environment before irrigating dress; It's three , marketing way have been unique , had been going carrying out the carbon dioxide cooling down and supplementing by the fact that fresh beer sells machine, have made use of carbon dioxide pressure to give beer and , have avoided beer contacting air but have produced oxide taste; It's four, has been that scheduled time is not long because of barrelled fresh beer guarantee quality , the dealer has born certain risk, if being able to not sell out in time, meeting bring about very big economic losses.

扎啤的价格比同等量的熟啤酒高3—5倍，究其原因以有下几个方面：其一，因为它是鲜啤酒，保持了啤酒良好的口味和营养；其二，生产过程中，无菌条件要求严格，设备投资大，在灌装前要经过膜过滤或孔过滤，除去所有的微生物，啤酒桶和生产环境也要严格无菌；其三，销售方式独特，要过通过鲜啤酒销售机进行降温和补充二氧化碳，并利用二氧化碳压送啤酒，避免了啤酒接触空气而产生氧化味；其四，是因为桶装鲜啤酒的保质期不长，经销商承担了一定的风险，如果不能及时售出，会造成很大的经济损失。
