Effect Of Build-in Straw Reactor And Outer Typer Recator On Solar Greenhose Environment And Tomato Physioiligicial Ecology

With the agricultural production scale expansion，agricultural production produces agreat deal of crops straw, however, most make crops straw fails to be effectivelyutilized,leading to great harm to ecological environment. Straw reactor technology couldtransform straw into CO₂and organic fertilizer, which could be utilized to solve CO₂deficiton the morning and afternoon of sunny day in anti-season solar greenhouse cultivation, andthe dependence of inorganic fertilizer. Therefore, this research is divided into two stages. Atthe first stage, I researched the effect of outer type strew reactor on solar greenhouse andtomato physiological ecology; At the first stage, I researched the effects of build-in and outertype strew reactor on solar greenhouse and tomato physiological ecology, in order to providedeep theoretical foundation and technical guidance.The main research contents and conclusion:1. In winter cultivation, the outer type reactor can can effectively solve morning andafternoon CO₂deficit; day and night the average temperature increases by2.0℃, airrelative humidity average inscends by4.5%.2. In autumn delayed cultivation, compared with Ck, outer type straw reactors caneffectively solve the sunlight Greenhouse CO₂deficit phenomenon in the process of theautumn delayed cultivation; built-in straw reactors can effectively relieve the CO₂deficitphenomenon; the outer type strew reactor and build-in strew reactor could make the dayand night average temperature increased by0.9℃and0.4℃respectively; Compared withthe control greenhouse, built-in straw reactor and the outer type straw reactor make solargreenhouse15cm deep soil temperature raise by about1℃。3. when compared with CK, in winter cultivation,the outer type reactor could significantlyincreas the net photosynthetic rate of vegetative stage and bearing fruit stage improve by19.5%and27.8%; significantly improving tomato vegetative stage’s and bearing fruitstage’s Chlorophyll content and tomato plant growth; the content of reducing sugar and Vc improve by6.41%、30.81%respectively and reducing organic acid is by30.55%;tomato fruit average weight increases by15.5%;tomato yield and economic benefitsimproved19.5kg/m2,59310yuan/hm.4. In autumn delayed cultivation, built-in straw reactor and outer type straw reactors maketomato vegetative and turn color stage of the net photosynthetic rate （Pn） significantlyincrease by29.6%,35%and12.8%,26.7%; increase the growth of tomato plant heightand promote early flowering, make tomato yield improve2.41kg/m21.95kg/m2...
