Phosphate-potaziyamu feteleza

Osati wamaluwa nthawi zonse amadziwa zomwe feteleza ndizo, ndi liti zomwe ziyenera kugwiritsidwa ntchito. Ndipo izi ndi zofunika kwambiri kudziwa, chifukwa pakuwapanga iwo amasintha mawonekedwe a nthaka yomwe zomera zimalandira zakudya zake, zomwe zimakhudza chitukuko chake.

Tsopano si vuto kugula feteleza, koma kuti musankhe bwino, muyenera kudziwa chomwe aliyense wa iwo akufuna. Kuchokera m'nkhaniyi, tiphunzira za kugwiritsa ntchito phosphorous-potaziyamu (feteleza phosphorous) kwa maluwa ndi feteleza.

Kodi fetereza ya phosphate-potassium ndi chiyani?

Izi ndizovuta feteleza, zomwe zimapanga phosphorous ndi potaziyamu. Tsopano pali chiwerengero chachikulu cha mankhwala a gulu ili, koma mosiyana mu kuchuluka kwa zigawo zazikulu ndi dzina la zinthu zina zowonjezera.

Mitundu yosiyanasiyana ya fetereza imakhala yotchuka kwambiri chifukwa chakuti ili ndi zinthu zochepa zomwe zimatsogolera ku salinization ya dziko lapansi.

Mitundu yayikulu ya feteleza ya phosphate-potassium

Kuti timvetse bwino chifukwa chake feteleza phosphate-potassium amagwiritsidwa ntchito, tiyeni tione makhalidwe a mitundu yawo.

Phosphoric-potashi fetereza "Autumn" . Zikuphatikizapo:

• phosphates -5%;
• potaziyamu - 18%;
• calcium - 8%;
• magnesiamu - 2.5%;
• boron - 0,2%.

Ndibwino kuti tigwiritse ntchito mmunda wamaluwa, zokongoletsa ndi wamaluwa nthawi izi:

• pamene kukumba - m'dzinja 35-60 g / m & sup2 kapena mu kasupe, koma kale limodzi ndi nitrojeni-yokonzekera;
• panthawi ya maluwa komanso panthawi ya fruiting, perekani 15-30 g / m & sup2 nthawi iliyonse mukamamasula ndi kumasula nthaka, ndiye kuti iyenera kuthiriridwa;
• kumapeto kwa zamasamba - pafupifupi mu September mu mlingo wa 30-40 g / m2 sup2. Izi ndi zofunika kuti nyengo yozizira ikhale yabwino komanso kusasitsa kwa mphukira.

Nitrofosca. Zomwe zimapangidwa zimaphatikizapo magawo ofanana (12% peresenti) potaziyamu, phosphorous ndi nitrojeni, zomwe zimapezeka mosavuta, choncho zinthu zonse zothandiza zimalowa mmera. Anapangidwa mwa mawonekedwe a imvi granules ndi pinkish tinge. Mlingo wogwiritsiridwa ntchito ndi 45-60 g pa 1 m & sup2. Ndibwino kuti muzigwiritse ntchito musanafese mbewu (ndikuyang'ana kumayambiriro kwa nyengo yachisanu) komanso m'nyengo ya chilimwe.

Nitroammophoska. Lili ndi phosphorous, nayitrogeni ndi potaziyamu, 17% ndi 2% sulfure. Lembani mu nthaka iliyonse 40-50 g pa m & sup2 mu kasupe mutabzalidwa, monga feteleza wamkulu, komanso m'chilimwe ngati feteleza.

Nitrophos . Zili ndi:

• 6% nayitrogeni;
• Calcium 11%;
• 16% phosphorous.

Zokwanira kuti feteleza m'maluwa ambiri.

Diammofosca. Ali ndi nayitrogeni (10%), potaziyamu (26%), phosphorous (26%), komanso pang'onopang'ono cha chitsulo, calcium, zinki, magnesiamu ndi sulfure. Amagwiritsidwa ntchito pa 20-30 g pa 1 m & sup2. Ndibwino kuti tigwiritse ntchito pafupifupi mitundu yonse.

Carboammofosca. Kapangidwe kameneko ndi:

• nitrogen 14-24%;
• phosphorous pentoxide 12-21%;
• K2O-12-16%.

Zapangidwa kuti nthaka isamalidwe musanagwe.

Manyowa a phosphate-potashi "AVA" . Chinthu chapadera chachidziwitso ichi cha feteleza yopangidwa ndi feteleza ndi chakuti alibe mpweya wa nayitrogeni, ndipo ndi mankhwala osungunuka. Zomwe zikuphatikizapo phosphorous ndi potaziyamu, komanso zinthu 9 zomwe zimathandiza kuti kukula kwa zomera kukule bwino.

Mukhoza kugwiritsa ntchito feteleza musanafese mbewu. Pali njira zingapo zopangira izi:

• kulowetsa inoculum;
• kubzala kapena kusakaniza ndi mbewu;
• kutsanulira nthaka ndi yankho la mankhwala awa.

Ngati mukufuna kugwiritsa ntchito feteleza zachilengedwe, ndiye kuti mungagwiritse ntchito phulusa , zomwe zimatengedwa kuti ndi zopatsa zovuta, zomwe zili ndi zinthu zingapo zofunika, kuphatikizapo potaziyamu ndi phosphorous. Mapulogalamu othandizidwa ndi makapu 3 pa 1 m & sup2.
