近jin幾ji年nian來lai，滴di灌guan在zai棚peng室shi中zhong使shi用yong的de越yue來lai越yue普pu遍bian
，用yong它ta澆jiao水shui和he施shi肥fei，菜cai農nong覺jiao得de得de心xin應ying手shou。然ran而er，如ru何he利li用yong滴di灌guan來lai對dui蔬shu菜cai灌guan根gen防fang病bing，很hen多duo菜cai農nong摸mo不bu著zhe門men道dao。不bu是shi用yong藥yao輕qing了le不bu管guan用yong，就jiu是shi用yong藥yao重zhong了le出chu藥yao害hai
，讓rang菜cai農nong很hen傷shang腦nao筋jin。那麼
，該怎樣利用滴灌對蔬菜藥劑灌根呢？下麵我們不妨聽一聽壽光市稻田鎮馬寨村種植高手馬金友的見解。

馬金友從去年開始使用滴灌，他認為，利用滴灌進行藥劑灌根
，須注意以下幾點：

一(yi)是(shi)要(yao)確(que)定(ding)好(hao)用(yong)藥(yao)量(liang)和(he)用(yong)藥(yao)濃(nong)度(du)。馬(ma)金(jin)友(you)介(jie)紹(shao)說(shuo)，在(zai)用(yong)藥(yao)前(qian)
，要(yao)先(xian)根(gen)據(ju)單(dan)株(zhu)用(yong)藥(yao)量(liang)計(ji)算(suan)出(chu)全(quan)棚(peng)植(zhi)株(zhu)的(de)用(yong)藥(yao)總(zong)量(liang)，然(ran)後(hou)將(jiang)藥(yao)劑(ji)兌(dui)水(shui)稀(xi)釋(shi)成(cheng)合(he)適(shi)的(de)濃(nong)度(du)，接(jie)下(xia)來(lai)，就(jiu)可(ke)以(yi)用(yong)配(pei)製(zhi)好(hao)的(de)藥(yao)液(ye)進(jin)行(xing)滴(di)灌(guan)。注(zhu)意(yi)用(yong)藥(yao)量(liang)和(he)兌(dui)水(shui)比(bi)例(li)一(yi)定(ding)要(yao)計(ji)算(suan)準(zhun)確(que)，切(qie)忌(ji)估(gu)摸(mo)著(zhe)來(lai)，以(yi)免(mian)出(chu)現(xian)灌(guan)根(gen)後(hou)效(xiao)果(guo)不(bu)好(hao)或(huo)出(chu)現(xian)藥(yao)害(hai)的(de)情(qing)況(kuang)發(fa)生(sheng)。

三(san)是(shi)要(yao)注(zhu)意(yi)藥(yao)劑(ji)灌(guan)根(gen)的(de)時(shi)間(jian)和(he)天(tian)氣(qi)。馬(ma)金(jin)友(you)說(shuo)，藥(yao)劑(ji)灌(guan)根(gen)和(he)灌(guan)清(qing)水(shui)一(yi)樣(yang)，對(dui)天(tian)氣(qi)都(dou)有(you)一(yi)定(ding)的(de)要(yao)求(qiu)。雖(sui)然(ran)使(shi)用(yong)灌(guan)滴(di)澆(jiao)水(shui)比(bi)傳(chuan)統(tong)澆(jiao)水(shui)棚(peng)內(nei)濕(shi)度(du)相(xiang)對(dui)較(jiao)小(xiao)
，但(dan)仍(reng)要(yao)做(zuo)好(hao)放(fang)風(feng)排(pai)濕(shi)工(gong)作(zuo)。因(yin)此(ci)，藥(yao)劑(ji)灌(guan)根(gen)一(yi)定(ding)要(yao)選(xuan)在(zai)一(yi)個(ge)晴(qing)好(hao)的(de)天(tian)氣(qi)時(shi)進(jin)行(xing)

，以(yi)上(shang)午(wu)10點以後進行最為合適。

最zui後hou
，馬ma金jin友you還hai強qiang調tiao說shuo，一yi般ban超chao過guo一yi畝mu的de棚peng，最zui好hao用yong兩liang根gen或huo三san根gen主zhu管guan道dao供gong水shui。因yin為wei大da棚peng超chao過guo一yi畝mu後hou

，隨sui著zhe使shi用yong的de滴di灌guan帶dai變bian長chang
，滴di灌guan內nei的de壓ya力li會hui有you所suo減jian弱ruo，很hen容rong易yi出chu灌guan藥yao不bu均jun的de情qing況kuang。因yin此ci，超chao過guo一yi畝mu地di的de大da棚peng
