1. Kuvandudza kuvandudzwa kwevhu uye chimiro chevhu
Fulvic acid ndeye humus zvinhu, izvo zvinogona kukanganisa zvimiro zvevhu uye kukurudzira kuumbwa kweiyo yakagadzikana yakaunganidzwa chimiro muvhu, ichiwedzera zviri mukati meaggregates ≥ 0.25mm muvhu ne10-20% uye organic zvinhu zvirimo. ne10%, iyo inogona kuchengetedza ivhu mwando , Kuwedzera kufefetedza kunobatsira pakukura kwembesa.
Wedzera kuchengetwa kwemvura kwevhu. Fulvic asidhi inonzi hydrocolloid ine simba rekutora mvura. Iyo yakanyanya kunyura mvura inogona kudarika 500%. Huremu hwemvura inotorwa kubva mumhepo yakazadza hunogona kusvika zvakapetwa kaviri huremu hwayo, iyo yakakura kupfuura yakajairwa mineral colloids; Fulvic acid inodzivirira kubuda kwezvirimwa, inoderedza kushandiswa kwemvura yevhu, uye inowedzera mvura yevhu maererano.
Wedzerai kuorera kwevhu. Fulvic acid pachayo inonzi organic acid, iyo isingangowedzere kuparara kwemaminerari muvhu, inopa ivhu chikafu, asiwo inowedzera kushanda kwezvokudya kuburikidza nekuoma. Se organic colloid, fulvic acid ine zvese zvakanaka uye zvakaipa zvinopomerwa, izvo zvinogona adsorb anions uye cations, kuitira kuti izvi zvinovaka muviri zvichengetedzwe muvhu uye zvisarasikirwe nemvura, uye zvakakosha pavhu rejecha kuti rivandudze. mwero wekushandiswa kwefetereza.
2. Kurudzira kutorwa kwemicro-fertilizer uye kugadzirisa kushomeka kwekudya kunovaka muviri
Izvo zvinoteedzera zvinhu mu fulvic acid chelation zvinoumba fulvic acid chelate inofamba zvakanyanya uye nyore kutorwa nezvirimwa, uye inopfuudzwa mukushaikwa kwekudya kunovaka muzvirimwa, zvichinyatso kugadzirisa kushomeka kwekudya. Fulvic acid inogona chelate nesimbi, zinc uye zvimwe zvinoteedzera zvinhu kugadzira fulvic acid trace element chelate ine yakanaka solubility uye inonyudzwa nyore nezvirimwa, izvo zvinogadzirisa kutsvuka kwemashizha nekuda kwekushomeka kwesimbi.
3. Kuvandudza kunaka kwechirimwa
Fulvic acid ine basa re surfactant, iyo inogona kuderedza kushushikana kwepamusoro pemvura uye emulsify uye kuparadzira mishonga yezvipembenene; inogona kuburitsa madhigirii akasiyana ehydrogen bond association kana ion exchange reaction nemishonga yakawanda yezvipembenene; inogona kuita muchero ruvara uye kukura mberi, zvakafanana The kuibva mugumisiro ethylene uye zvichingodaro.
4. Kuramba kwakasimba kwechirwere
Fulvic acid inowedzera zvakananga zviri mukati mevhu organic matter uye inopa yakanakisa nharaunda kune anobatsira tupukanana. Huwandu hunobatsira hunowedzera zvishoma nezvishoma sehuwandu hwevanhu uye hunodzivisa kukura kwezvirwere zvinokuvadza. Mukuwedzera, zvinomera pachazvo zvinokura zvakasimba nekuda kwemamiriro akanaka evhu uye kusimbisa kudzivirira zvirwere. , Nokudaro kuderedza zvakanyanya kuitika kwezvirwere, kunyanya zvirwere zvinokonzerwa nevhu. Pamusoro pezvo, fulvic asidhi ine pachena inhibitory effect pafungi, uye inogona kudzivirira zvirwere zvakawanda zvinokonzerwa nefungi.
Fulvic acid ndiyo yakanakisa chikamu chevhu humus. Haikwanise chete kuderedza mutoro pazvirimwa, kuwedzera kubereka kwevhu, uye kupfumisa substrate yebhakitiriya yevhu, asiwo kuwedzera goho uye kunaka kwezvirimwa, nokudaro zvichibatsira varimi kuwedzera kugadzirwa, kuvandudza kunaka, uye kudyara ivhu. Zvinangwa zvenguva refu.
