Research Of Banana Anti-chilling With Different Measures

The author discussed the main reasons that banana live through the winter at different procreation, that lead banana chilling damage. the author through observation and track record and analyze data including the highest and the lowest temperature and relative humidity(RH) and so on, the author discussed the best effect. meantime, at room artificial simulative chilling the author discussed the best concentration through spurt different medicaments at different leveles. the main conclusion as follows:1.Research of banana anti-chilling at different agriculrure measuresThe author analyzed and check up different effect at dfferent physical measure through some weather data including the highest and the lowest temperature and RH and so on. The results showen, Bomofugai(BM),Lanmotaodai(LD) > Langmotaoguo(LG) is the best measure for banana anti-chilling, because that measures can prominence enhance the highest temperature in film, keep upper temperature at cold winter, can enhance RH in film, keep upper RH; can enhance the ground temperature in film and so on. Thereinto, BM can enhance plantlets high and stem diameter and leaf growth every more 61.04%,9.96% and 32.7% than CK; LD was more 62.48 %,37.15% and 21.43% than CK; Taojing result in banana plantlets died because the plantlets was been Injured.2.Research of banana anti-chilling at different chemistry control measuresThe author discussed the best protection concentration through spurt different chymic things including choline chloride(CC) and Nongjiale1(NJL1) and Nongjiale2(NJL2).the results showen, banana plantlets spurt CC can enhance banana solubility sugar(SS) and solubility protein(SP) content, reduce cell saturation potential,prevent cell lose more solutes; reduce malonyldialdehyde(MDA) bringed , Protect cell membranaceous and anti-damage; enhance peroxide(POD) and catalase(CAT) enzyme activity, clear out super-oxygen negative ion; reduce relatively conductance(REC) rate; enhance chlorophyl(CHL) content, keep higher photosynthesis rate and so on, when Its concentration was 50mg/L and the temperature sustaining fall artificial;Nongjiale1(NJL1) also can enhance proline (Pro) content etc.the best anti-chilling effects with Nongjiale1(NJL1) and Nongjiale2(NJL2) are when their concentration are diluted 50 and 40 Multiple separately.
