【摘要】：本試驗(yàn)為期8個(gè)月,分為兩個(gè)階段,第一階段為基于酸堿滴定技術(shù)研發(fā)測(cè)定養(yǎng)殖塘生石灰需要量的方法;第二階段為4種不同劑量有機(jī)肥,共12組池塘,每組設(shè)3個(gè)重復(fù),分析不同劑量有機(jī)肥對(duì)養(yǎng)殖池塘水質(zhì)、生石灰溶解性的影響和羅非魚(yú)產(chǎn)量的影響。比較施加不同劑量有機(jī)肥和石灰石溶解性,在羅非魚(yú)養(yǎng)殖塘中的效果,所研究結(jié)果可以為今后天然有機(jī)肥的開(kāi)發(fā)利用提供理論依據(jù),也為確定池塘底泥石灰需要量提供數(shù)據(jù)參考。主要研究結(jié)果如下:1、池塘生石灰需要量的測(cè)定1)通過(guò)鉀離子-碳酸氫鹽法所測(cè)定的魚(yú)塘石灰總需要量比PB石灰需要測(cè)定法得到的石灰需量精確度度上高出9.6%到27.2%(平均為12.9%)。2)鉀離子-碳酸氫鹽法的測(cè)定過(guò)程中只包含兩種化學(xué)試劑,而且不包含有毒化學(xué)試劑,也不需要用到機(jī)械搖床,pH酸度儀和較低的測(cè)定成本。2、施加有機(jī)物對(duì)養(yǎng)殖塘水質(zhì)、生石灰溶解性的影響和羅非魚(yú)生長(zhǎng)的影響:1)不同劑量有機(jī)肥對(duì)水體溫度、pH、導(dǎo)電率、葉綠素a、總硬度、硝酸鹽氮(NO3-N)、總氨氮(TAN)含量影響不顯著(p0.05),在養(yǎng)殖池塘中含量比較穩(wěn)定;總堿度、鈣-硬度、總磷(TP),可溶性活性磷(SRP)影響顯著(p0.05),在不同有機(jī)肥劑量處理組和對(duì)照組中這些指標(biāo)有顯著性差異。2)驗(yàn)證了在土壤中施加有機(jī)肥增加二氧化碳的釋放將會(huì)增加石灰石的溶解度進(jìn)而提高總堿度。3)不同劑量有機(jī)肥對(duì)體重增加百分比,生長(zhǎng)率(SGR),都沒(méi)有顯著影響(p0.05);不同劑量有機(jī)肥對(duì)體重增加量、總產(chǎn)量和凈產(chǎn)量在數(shù)值上有明顯差異,羅非魚(yú)總產(chǎn)量從1073.25到1260.75千克/公頃,中有機(jī)肥劑量組獲得最高凈產(chǎn)量為1010千克/公頃。綜合比較試驗(yàn)中提出的石灰需要量確定法和四種不同劑量有機(jī)肥對(duì)水質(zhì)指標(biāo)、石灰石溶解性和羅非魚(yú)生長(zhǎng)的影響,在考慮生態(tài)效益和經(jīng)濟(jì)效益的情況下,以中有機(jī)肥料處理組和依據(jù)鉀離子-碳酸氫鹽法來(lái)加入適宜劑量石灰石的組合可以提高總堿度,為最佳組合方案。
[Abstract]:The experiment lasted for 8 months and was divided into two stages. The first stage was based on acid-base titration technology to determine the requirement of quicklime in culture pond, the second stage was four different doses of organic fertilizer, 12 groups of ponds were divided into 12 groups with 3 replicates in each group. The effects of different doses of organic fertilizer on the water quality, the solubility of quicklime and the yield of tilapia were analyzed. The effects of different doses of organic fertilizer and limestone solubility on tilapia culture pond were compared. The results can provide theoretical basis for the development and utilization of natural organic fertilizer in the future. It also provides a data reference for determining the lime requirement of pond sediment. The main results are as follows: 1) the total lime requirement of fish ponds determined by potassium ion-bicarbonate method is 9.6% to 27.2% higher than that obtained by PB lime requirement method. The potassium ion-bicarbonate method contains only two chemical reagents, And it does not contain toxic chemical reagents, nor does it require a mechanical shaking table pH acidity meter and a lower cost of determination. The effects of different doses of organic fertilizer on water temperature pH, conductivity, chlorophyll a, total hardness, nitrate nitrogen (NO3-N) and total ammonia nitrogen (TAN) were not significant (p0.05). Total basicity, calcium hardness, The effect of total phosphorus (TP), soluble active phosphorus (SRP) was significant (p0. 05). These indexes were significantly different in different organic fertilizer treatment groups and control groups. It was proved that adding organic fertilizer to soil would increase the release of carbon dioxide from limestone. In turn, the solubility of organic fertilizer increased the percentage of body weight increased with different doses of organic fertilizer, and the total alkalinity of organic fertilizer was increased by 3. 3%. Growth rate (SGR),) had no significant effect on body weight gain, total yield and net yield of tilapia from 1073.25 to 1260.75 kg / ha. The maximum net yield of medium organic fertilizer group was 1010 kg / ha. The effects of lime requirement determination method and four different doses of organic fertilizer on water quality index, limestone solubility and tilapia growth were comprehensively compared, and ecological and economic benefits were considered. The combination of medium organic fertilizer treatment group and potassium ion-bicarbonate method can increase the total alkalinity and is the best combination scheme.
