Ipi iyo potassium fertilizer ye tomate yakanakisisa?

Chii chiri kuitika uye mumhando ipi inoshandiswa potassium fertilizer? Kushandiswa kwezvinhu izvi mukurima kunotora nzvimbo inokosha, sezvo potasium oxide inofanirwa kukura kwakanaka kwemiti yakawanda. Zvinhu zvakakosha zvekugadzirwa kwechigadzirwa ichi zvinowanikwa muUrials nenzira yehuta ye cainite, sylvinite, carlinite, sheinite, nezvimwewo. Izvozvi, michina yakaoma (cainite ney sylvinite) inoparadzaniswa nenzira yekugadzira, pamwe chete nezvinhu zvinowedzera zvakaoma makemikari.

Ndeapi rudzi rwemashonga e-potashi hunokonzerwa nemakemikari emazuva ano? Izvi zvinonyanya kunzi calimagnesium (potassium oxide - kusvika 25-26%, inogadzirwa nemagesium - inenge 11-18%, haina chlorine), Kalimag (potassium oxide inenge 24%, hainawo chlorine inogadzirwa), potassium munyu (yakabatanidzwa Iforomu ye sylvinite uye potassium chloride, potassium oxide - inopfuura 40%, yakakura yeklorini).

Potassium fertilizer yematato inomiririrwa zvikuru ne potassium chloride uye potassium sulfate. Chokutanga chezvi ndechichena chekristalline powder, inogadziriswa mumvura. Potassium chloride inogadzirwa kubva ku sylvinite nokubvisa kusvibiswa kune dzimwe nyika, zvichiita kuti iongorore huwandu hwezvinhu zvinobatsira (kusvika 62% ye potassium oxide). Izvo zvinokonzerwa nehutachiwana hazvikwanise kunyorova, saka hazviiti keke, zvinogona kuchengetwa mumidziyo yepurasitiki uye nyore nyore kuendeswa kunyika.

Potassium fertilizer yemamateti akaita se potassium chloride inotangwa muvhuvhu, kuitira kuti kuwedzerwa kweklorini "kwakasara" mumativi akadzara evhu uye kusina kuwanikwa pamidzi yemiti. Asi chimwe chinhu-potassium sulfate-isina kukwana kwakadai kweklorini mumakemikari, iyo inobvumira kuti ive iyo inoshandiswa zvakanyanya kushandiswa kweyikirasi panguva ino.

Zvikamu zve potassium sulphate zvinoshandiswa sechinhu chinokosha kana chitubu-chirimu potassium fertilizer ye tomate. Maitiro avo emakemikari (anenge matatu muzana magnesium, 18% sulfuri uye anenge 50% potassium oxide) anobatsira kudzivirira mashizha emashizha uye kuwana kukohwa kwakanaka. Kuwanda kwemushonga kunosarudzwa pane imwe neimwe mumamiriro ezvinhu, zvichienderana nemamiriro emamiriro ekunze, acidity yevhu, chigadziko chekushanduka kwezvirimwa, zvakasiyana-siyana zvezvirimwa uye zvimwe zvirongwa zvakatangwa. Somuenzaniso, kuiswa kwemuriwo (nitrogen boka) kunoderedza kushanda kwekusimudzirwa kwe potassium fertilizer. Lucerne, akadyarwa pamberi pematato, achatora potasium yakawanda kubva muvhu, uye zviyo, pane zvinopesana, hazvirevi chinhu ichi.

Kuti potash fertilizer ye tomato yakakosha zvikuru, unoda kuverenga mazinga ekushandiswa. Kuti uite izvi, zvinoda kuziva kuti yakawanda sei potassium iri mundima (unogona kuraira chidzidzo mune ma laboratori chaiwo). Mushure meizvi, unoda kuziva huwandu hwezvinhu zvakachena zvaunoda iyi girasi (taura magiramu 20 etazasiyamu pamamita akare) uye uverenge chiyero chinodikanwa chemajeri. Mukati medu, kuti mbeu yacho yakagamuchira 20 g. Potassium, iwe unofanirwa kutora, somuenzaniso, 40 gramu ye potassium sulphate, nokuti iyo hafu inosanganisira oxide yechinhu chatinoda. Nzira iri nyore, asi isiri yakarurama yekugadzirisa zvinowanzoitwa ndeyekutevera mazano pamusoro pekuiswa kweimwe rudzi rwemumanyorera.
