秸秆生物反应堆对设施‘夏黑’葡萄生长发育的影响

Effects of straw bioreactor on growth and development of'Summer Black'grape in greenhouse

为了研究秸秆生物反应堆对葡萄生长发育的影响,以4年生‘夏黑’葡萄为试材,在日光温室内建设内置式秸秆生物反应堆,以常规栽培管理为对照,研究秸秆生物反应堆技术对日光温室葡萄生长发育、果实品质,以及对日光温室葡萄根系不同深度地温及室温的影响。结果表明:通过使用秸秆生物反应堆技术可以促使日光温室地温提高1.5 ℃,物候期提前3~6 d,新生枝条的生长量、果穗长度及穗质量等方面优于常规管理的葡萄。说明使用秸秆生物反应堆能够提高土壤温度和空气温度,对葡萄的生长发育、果实品质具有促进作用。

In order to study the effect of straw bioreactor on grape growth and development,4-year-old'Summer Black'grape was used as a material,a built-in straw bioreactor in sunlight greenhouse was set as a treatment,with conventional cultivation management as a control.Effects of straw bioreactor technology on grape growth and fruit quality in greenhouse,and the influence of this technology on temperature of air and ground in different depth was studied.The results showed that the ground temperature of greenhouse could be increased by 1.5℃and the phenological period could be advanced by 3 to 6 days with applying straw bioreactor technology.The growth of new branches,cluster length and cluster weight were better than those of grapes with conventional management.It showed that straw bioreactor could improve soil temperature and air temperature,and promote grape growth and fruit quality.
