翠冠梨大棚栽培光温变化及生长发育规律研究

利用连栋塑料大棚栽培翠冠梨,研究大棚中的光温变化、梨树生长发育规律及其相关性.结果表明:大棚栽培通过塑料薄膜的保温作用明显提早了梨树的物候期,其中果实成熟期比露地提早了近1个月;大棚栽培促进了梨树各生长器官的发育,新梢长度、果柄长度、果实重量均有明显的提高.实验证明温度和湿度的调控是大棚栽培中两个重要的管理环节.

Study the Changes of Light intensities and Temperatures and the Rules of Growth and Development of 'Cui Guan' Pear Cultivated in Plastic House

The changes of light intensities,temperatures,and the growth and development rules of 'Cui Guan' pear cultivated in plastic house were studied.The results indicated that the phonological phases of the trees cultivated in plastic house were significantly earlier than those cultivated in open ground,especially the fruit ripening stage was about one month earlier.Also,compared with cultivated in open ground,the lengths of shoot,carpopodium and the weight of the fruit were increased obviously when cultivated in plastic house.It is considered that the control of temperature and humidity in plastic house is the key step for cultivation of the pear.
