Tsvagiridzo yeMicroalgae Bio-stimulant neSyngenta China

Munguva pfupi yapfuura, Extracellular Metabolites yeHeterotrophic Auxenochlorella protothecoides: A New Source of Bio-Stimulants for Higher Plants yakaburitswa online mumagazini yeMarine Drugs nePROTOGA neSyngenta China Crop Nutrition Team. Izvi zvinoratidza kuti kushandiswa kwemicroalgae kuri kuwedzerwa mumunda wekurima, zvichiongorora kugona kwayo kwebio-stimulants kumiti yepamusoro. Kushanda pamwe chete pakati pePROTOGA neSyngenta China Crop nutrition team kwakaratidza uye kwakasimbisa kugona kwe extracellular metabolites kubva mumvura ye microalgae tail se bio-fertilizer itsva, zvichiwedzera kukosha kwehupfumi, hushamwari hwezvakatipoteredza uye kugara kwenguva refu kwemaitiro ese ekugadzira microalgae mumaindasitiri.

▲Mufananidzo 1. Chidimbu chemifananidzo

Kurima kwemazuva ano kunoenderana nefetereza yemakemikari zvakanyanya, asi kushandiswa zvakanyanya kwefetereza yemakemikari kwakakonzera kusvibiswa kwezvakatipoteredza muvhu, mumvura, mhepo uye kuchengetedzeka kwechikafu. Kurima kwegirini kunosanganisira nharaunda yakasvibirira, tekinoroji yegirini uye zvigadzirwa zvegirini, izvo zvinokurudzira kushandurwa kwekurima kwemakemikari kuenda kurima kwezvakatipoteredza izvo zvinonyanya kuvimba nemaitiro emukati mehupenyu uye zvinoderedza kushandiswa kwefetereza yemakemikari nemishonga yekuuraya zvipembenene.

MaMicroalgae zvisikwa zvidiki zvinogadzira photosynthesis zvinowanikwa mumvura yakachena uye mugungwa zvinokwanisa kugadzira zvinhu zvakasiyana-siyana zvinoshanda mumuviri zvakaita semapuroteni, mafuta, macarotenoids, mavhitamini, uye mapolysaccharides. Zvakataurwa kuti Chlorella Vulgaris, Scenedesmus quadricauda, ​​Cyanobacteria, Chlamydomonas reinhardtii nedzimwe microalgae zvinogona kushandiswa seBio-stimulant ye beet, domasi, alfalfa nezvimwe zvigadzirwa zvekurima zvinobatsira kuvandudza kumera kwembeu, kuunganidzwa kwezvinhu zvinoshanda uye kukura kwezvirimwa.

Kuti ishandisezve mvura yemuswe uye kuwedzera kukosha kwehupfumi, ichibatsirana neSyngenta China Crop Nutrition Team, PROTOGA yakadzidza nezvemhedzisiro yeAuxenochlorella protothecoides tail water (EAp) pakukura kwezvirimwa zvepamusoro. Zvakabuda zvakaratidza kuti EAp yakasimudzira zvikuru kukura kwezvirimwa zvepamusoro uye yakawedzera kudzivirira kushushikana.

▲Mufananidzo 2. Mhedzisiro yeEAp pamiti yemuenzaniso

Takaona nekuongorora ma metabolites ari kunze kwemuviri muEAp, uye takaona kuti paive nemakomputa anopfuura 84, anosanganisira 50 organic acids, 21 phenolic compounds, oligosaccharides, polysaccharides nezvimwe zvinhu zvinoshanda.

Chidzidzo ichi chinofungidzira kuti mashandiro acho anogona kuitwa: 1) Kuburitswa kwema organic acids kunogona kukurudzira kunyungudika kwema metal oxides muvhu, nokudaro zvichivandudza kuwanikwa kwezvinhu zvidiki zvakaita se iron, zinc ne copper; 2) Phenolic compounds dzine antibacterial kana antioxidant effects, dzinosimbisa madziro esero, dzinodzivirira kurasikirwa nemvura, kana kushanda sema signal molecules, uye dzinoita basa guru mukupatsanurwa kwemasero, kutonga kwemahormone, photosynthesis activity, nutrient mineralization uye kubereka. 3) Microalgae polysaccharides inogona kuwedzera huwandu hwe ascorbic acid uye mabasa e NADPH synthase uye ascorbate peroxidase, nokudaro ichikanganisa photosynthesis, masero kupatsanurwa uye abiotic stress tolerance yemiti.
