不同作物秸秆生物反应堆对日光温室樱桃番茄生长、生育环境及其产量的影响

Impact of Different Crop Straw Bio-reactor on Environmental Fators of Solar Greenhouse and Growth and Yield of Cherry Tomato

针对目前秸秆生物反应堆秸秆种类使用较为杂乱的问题,筛选适用于日光温室樱桃番茄种植的生物反应堆的秸秆作物种类,为日光温室樱桃番茄生产应用秸秆生物反应堆技术提供依据。试验选取常见的小麦、水稻、玉米、油葵4种作物秸秆,通过应用秸秆生物反应堆技术,测定秸秆生物反应堆对日光温室环境、樱桃番茄农艺性状、抗病性和产量等指标的影响,以常规栽培为对照,对其效果进行综合评价。结果表明,与对照相比,4个不同秸秆处理的生物反应堆均能提高温室土壤温度和CO2体积分数,促进樱桃番茄生长,提高产量,降低晚疫病的发病率。其中小麦秸秆反应堆处理下土壤温度分别较对照提高3.2℃,温室内湿度较对照下降21.1%,番茄晚疫病发病率较对照降低56.6%,番茄产量较对照增幅达19.5%。因此,在日光温室樱桃番茄栽培中,应用小麦秸秆生物反应堆技术的综合效应最好。

The study is aiming at the straw straw bio-reactor types use the more cluttered,screening for cherry tomato in solar greenhouse of plant biological reactor stalk crops to provide technical support and theoretical basis for the production and application of straw bio-reactor technology of cherry tomato in sunlight greenhouse.The test selects local common wheat straw,rice straw,corn straw,oil sunflower straw four crops,through the application of straw bio-reactor technology,to determine the effects of bio-reactor on greenhouse environment,cherry tomato,agronomic traits,disease resistance and yield index,using conventional cultivation as control,a comprehensive evaluation of their effectiveness.The results show that：compared with the control group,four different straw bio-reactors could increase soil temperature and CO2 volume fraction,promote the growth and development of cherry tomato,increase production,and reduce the incidence of late blight.The wheat straw reactor temperature of soil increased by 3.2 ℃,humidity drops by 21.1%,late blight incidence decreased 56.6%,and yield increased by 19.5%.Therefore,in cherry tomato cultivation in solar greenhouse,application of wheat straw bio-reactor technology has the best comprehensive performance.
