Potassium Nitrate As Preservative

Abstract

Xaus

Vim muaj ntau yam teebmeem ntawm sucrose ntawm cov paj txiav gladiolus, nws tuaj yeem hloov lub zog raws sijhawm rau kev txiav cov ceg, txhim kho kev noj zaub mov zoo ntawm cov paj txiav, thiab txhawb lub neej kev ua ub no ntawm txiav paj. Txawm li cas los xij, hauv kev kho mob ntawm P3 thiab P5, nws feem ntau cuam tshuam los ntawm inhibition ntawm Cu2. Potassium nitrate li preservative yog ib qho kev xaiv zoo; nyob rau hauv cov mis P4 ntxiv nrog poov tshuaj nitrate, vim l<10 can increase the osmotic pressure of solution and the tension of petal cells, it is conducive to water balance, thus maintaining the posture of flowers. In addition to the interaction of sucrose, P4 treatment has the highest ornamental value.

1) Copper sulfate, vim nws cov concentration siab, tsis tsuas yog tsis tuaj yeem nce nws cov txiaj ntsig zoo nkauj, tab sis kuj muaj cov tshuaj lom rau cov paj txiav.

2) Potassium ions los ntawm poov tshuaj nitrate raws li preservative yuav ua rau kom lub osmotic siab ntawm kev daws thiab qhov nro ntawm cov paj hlwb, uas yog conducive rau dej tshuav nyiaj li cas thiab tswj lub paj posture thiab zoo heev txhim kho cov ornamental nqi ntawm txiav gladiolus paj.

3) Qhov hnyav tshiab yog txiav txim siab los ntawm ob qho tib si evapotranspiration tus nqi thiab tus nqi nqus. Thaum ob qhov sib npaug, qhov hnyav tshiab nce mus txog qhov siab tshaj plaws. Qhov nce hauv qhov hnyav, rau qee qhov, prolongs lub senescence ntawm txiav paj.

4) Los ntawm kev soj ntsuam tag nrho ntawm morphological thiab physiological ntsuas, mis P4: 3g potassium nitrate + 20 g sucrose + 1 l dej kho yog ib qho zoo tagnrho formula rau khaws cia ntawm txiav gladiolus paj.
