【摘要】：通過(guò)綜合分析番茄秸稈厭氧發(fā)酵及有氧發(fā)酵漚制液態(tài)有機(jī)肥的理化性狀及番茄育苗效果,對(duì)番茄秸稈漚制液態(tài)有機(jī)肥效果進(jìn)行評(píng)價(jià),探求番茄秸稈漚制液態(tài)有機(jī)肥的合理方法。本試驗(yàn)以番茄秸稈為試驗(yàn)材料,以厭氧發(fā)酵組(T1組,番茄秸稈:清水=1g:5mL)、有氧發(fā)酵組(T2組,番茄秸稈:清水=1g:2mL)為處理組,清水為對(duì)照組(CK組),進(jìn)行為期90天的發(fā)酵試驗(yàn)。測(cè)定有機(jī)肥制備過(guò)程中各組營(yíng)養(yǎng)元素含量及番茄幼苗苗期生長(zhǎng)過(guò)程中的形態(tài)指標(biāo)和生理指標(biāo),運(yùn)用Excel和DPS軟件進(jìn)行數(shù)據(jù)處理,對(duì)番茄秸稈漚制液態(tài)有機(jī)肥效果綜合評(píng)估。試驗(yàn)表明,番茄秸稈厭氧發(fā)酵漚制液態(tài)有機(jī)肥的全氮、全磷、速效氮、速效鉀均高于其他處理,呈現(xiàn)極顯著性差異,番茄秸稈有氧發(fā)酵漚制液態(tài)有機(jī)肥的全鉀、速效磷、有機(jī)質(zhì)、EC值高于其他處理;番茄秸稈厭氧發(fā)酵漚制液態(tài)有機(jī)肥處理的番茄幼苗株高、莖粗、葉面積、地上/下部分鮮重、地上/下部分干重、根冠比、壯苗指數(shù)均高于其他兩組處理。番茄秸稈厭氧發(fā)酵漚制液態(tài)有機(jī)肥是對(duì)番茄秸稈高效資源化處理和養(yǎng)分再利用的較好途徑之一。
[Abstract]:Based on the comprehensive analysis of the physical and chemical properties of tomato straw anaerobic fermentation and aerobic fermentation retting liquid organic fertilizer and the effect of tomato seedling raising, the effect of tomato straw retting liquid organic fertilizer was evaluated, and the reasonable method of tomato straw retting liquid organic fertilizer was explored. In this experiment, tomato straw was used as experimental material, anaerobic fermentation group (T1 group, tomato straw: clear water = 1g:5mL), aerobic fermentation group (T2 group, tomato straw: clear water = 1g:2mL) as treatment group and clear water as control group (CK group) for 90 days. The contents of nutrient elements in each group during the preparation of organic fertilizer and the morphological and physiological indexes during seedling growth of tomato seedlings were determined. The data were processed with Excel and DPS software to evaluate the effect of tomato straw retting liquid organic fertilizer. The results showed that the total nitrogen, total phosphorus, available nitrogen, available potassium and available potassium of the liquid organic fertilizer were significantly higher than those of other treatments. The plant height, stem diameter, leaf area, aboveground / lower part fresh weight, aboveground / lower part dry weight, root / shoot ratio of tomato straw treated by anaerobic fermentation and retting liquid organic fertilizer were higher than those of other treatments. The seedling index was higher than that of the other two groups. The composting of liquid organic fertilizer by anaerobic fermentation of tomato straw is one of the better ways to treat tomato straw efficiently and reuse nutrients.
