The Effect Research Of Winter Soil Heating And Air Heating In Solar Greenhouse

The temperature of the solar greenhouse(temperature and soil temperature)is particularly important for production.The effect of the winter and the annual production of the ventricle is significant.This study of sunlight greenhouse soil,irrigation water in winter heating and hot blast stove air heating,heating water irrigation and straw reactor heating impact on tomato growth,physiological index and yield,and the soil environment,the influence of plant roots and yield,the analysis of different furnace heating effect and economic benefit.The results showed that:First,winter irrigation water heating effects on winter greenhouse tomato growth.After the irrigation water heating can make the 0 cm,to 10 cm,20 cm,30 cm soil temperature increased by 18.5? to 34.4 0C,respectively,15.4 ? to 28.4?,10.9? to 20.1 ?,12.2 ? to 14.3?,after 5 to 8 h soil temperature to stabilize.Found 35 ? temperature on plant height,stem diameter,flowering plant number,the number,leaf area,chlorophyll content,plant root morphology index,fruit yield and quality has the remarkable difference compared with CK,14.2%increase the plant height,stem diameter increased 12.6%,the number increased by 49.2%as a result,flower number increased by 36.8%,leaf area,chlorophyll content increased by 27.1%,a 25.2%increase in total root length increased by 14.2%,root surface area increased by 21.1%,the root dry weight increase was not significant,single fruit weight increased by 27.4%,total output increased by 16.35%,36.9%increased syncope,vitamin C significantly increased by 6.1%,soluble sugar increased by 9.9%,total acid increased by 11.9%,water heating system cost minimum 1750 yuan;Relatively low running cost 237.6 yuan/stubble.Second,the built-in straw reactor heating effects on winter greenhouse tomato growth.Indoor cultivation period 0 cm soil temperature T1(16.8?)>T2(16.4?)>CK(15.6?),10 cm soil temperature T1(16.8?)>T2(16.2?)>CK(15.0?),20 cm soil temperature T1(16.4?)>T2(15.5 ?)>CK(13.2 ?),30 cm soil temperature T1(16.6?)>T2(15.8 ?)>CK(14.4?).T1,T2 processing respectively were 7.8%and 14.2%increase the plant height,stem diameter were 5.5%and 13.3%,13.3%and 27.1%of chlorophyll,the results were 27.7%and 49.2%,flower number,leaf area of 12.1%and 25.2%,14.7%and 14.7%.Increased 10.5%and 10.7%total root length,root surface area by 7.8%and 8.4%,7.1%and 12.5%average diameter,root fresh weight 13.8%and 16.3%,11.6%and 14.4%,root dry weight.Improve the fruit weight of 20.0%and 27.4%,plot yield 8.2%and 10.5%,total output of 14.22%and 16.35%,syncope CK35.7%and 36.9%,5.2%and 6.1%vitamin C,soluble solids 29.0%7.0%and 9.9%,soluble sugar,total acid 11.9%and 11.9%.T1,T2 treatment compared with CK on output value and profit are higher than CK2050 yuan and 200 yuan,1944 yuan and 344 yuan.Third,several kinds of hot blast stove heating effect on seedling in greenhouse environment.Indoor the highest average temperature in greenhouse I,greenhouse II 2.4?,higher than that of higher greenhouse ? 1.1?,5.1? higher than CK greenhouse,YK-200 type and the NFL-500 type hot blast stove heating effect is obvious,so crops is not threatened by chilling injury.R2,R1 and CK greenhouse average minimum temperature 12.4?,10.1? and 6.7?,respectively.An average humidity of 85.04%,87.99%and 90.61%respectively;Average daily coal consumption is 55.5 kg and 31.5 kg respectively,different heating equipment YK-200 type,CK-100 type,the NFL-500 type,electric heating and solar heating one-time expenses:1:1:0.3:0.62:3.5;every 667 m~2 NFL-500 type coal-fired stove with minimum cost,operation cost about 46.34 yuan/667 m~2.
