Makemake ʻo Cyperus rotundus e ulu ma ka ʻāina paʻa, a ʻoi aku ka koʻikoʻi o ka ulu ʻana o ka lepo one.Ma nā wahi kulina a me ke kō, ʻoi aku ka paʻakikī o ka mālama ʻana iā Cyperus rotundus.

Lilo pinepine ia i wahi kaiāulu liʻiliʻi a hui pū ʻia me nā mea kanu ʻē aʻe e hoʻokūkū ai no ka nani, ka wai, a me ka mea momona, e ulu ʻino ai nā mea kanu ʻē aʻe.ʻO ia hoʻi ka pūʻali o nā mea kanu i ke kua keʻokeʻo, nā ʻōpala pilau ʻeleʻele, nā pīkī hao a me nā mea ʻē aʻe.ʻO ia kekahi o nā mea ʻino loa o ka honua.

Ma muli o nā aʻa ʻōpuʻu kūikawā o Cyperus rotundus, ʻo ke kī o ka weeding ʻo ka pepehi ʻana i nā aʻa.

Nā ʻano hoʻomalu kemika:

1. Kaina

Benazone — Hoʻohana ʻia i ka lau ʻana o ka kulina 4-6, hana maikaʻi kēia huahana i ke kiʻekiʻe o ka mahana, akā maikaʻi ʻole ka hopena ke haʻahaʻa ka mahana.Hoʻohana ʻia me ka akahele i ka ua nui a i ʻole nā ​​makahiki maloʻo.Palekana ʻo Benzopine no ka mea kanu hope.

Chlorpyrisulfuron - Hoʻohana pinepine ʻia kēia herbicide ma hope o 3-5 lau kulina.He hopena maikaʻi kona ma luna o ka mauʻu laulaʻa a me ka sedge, a he ʻano paʻa, akā lohi ka wikiwiki o ka mauʻu e make ana.ʻOi aku ma mua o ka hapalua mahina e make loa i ka mauʻu.ʻAʻole ʻōlelo ʻia a maikaʻi ʻo Fast dimethyl tetrachloride a me nā mea hoʻohana like ʻole, i ʻole e hoʻopuka i ka antagonism.

Glyphosate — Ma hope o 10 mau lau kulina, ke oi aku ma mua o ka hapalua mika, hiki iā ʻoe ke hoʻohana i ka glyphosate (glyphosate me ka ʻole o nā mea ʻē aʻe) no ka pīpī ʻana i ka mauʻu me ka wai, e hoʻolohe i ka pulu kuhikuhi, ʻaʻole e kāpī i ka kulina, ʻo ke kumu o ka weeding. hoʻohana i ka mauʻu A me ke kūlana ʻokoʻa ma waena o nā mea kanu.

2. Māla ʻai

Manaʻo maʻamau ka hoʻohana ʻana i ka dimethyl•metazone, glyphosate, a me glufosinate no ka pulupulu kuhikuhi ʻana, a e makaʻala ʻaʻole e pulu i nā kumulāʻau hua.

Inā ʻōlelo ʻoe e hiki ke ʻeli lima ʻia kāu hapakolu o ka ʻeka, hiki iā ʻoe ke wehe loa i ka Radix Aconiti i loko o 2 a 3 mau makahiki.

E kelepona iā mākou ma o ka leka uila a me ke kelepona no ka ʻike hou aku a me ka ʻōlelo
