　　2.根據土(tu)(tu)壤(rang)情況(kuang)進行施(shi)肥如采用隨(sui)水追肥，用量(liang)(liang)(liang)大小應看土(tu)(tu)壤(rang)情況(kuang)。土(tu)(tu)壤(rang)較干，濃(nong)度(du)要(yao)(yao)低(di)，追肥數量(liang)(liang)(liang)要(yao)(yao)多一些。土(tu)(tu)壤(rang)濕潤時(shi)，濃(nong)度(du)要(yao)(yao)高些，用肥數量(liang)(liang)(liang)要(yao)(yao)少(shao)。沙性土(tu)(tu)壤(rang)保水保肥能力差，要(yao)(yao)量(liang)(liang)(liang)少(shao)多施(shi)。粘性土(tu)(tu)壤(rang)保水保肥能力強，施(shi)肥次數應少(shao)，但每(mei)次的施(shi)肥量(liang)(liang)(liang)要(yao)(yao)多一些。

　　3.根據天(tian)氣(qi)變化(hua)施(shi)(shi)肥(fei)(fei) 因溫(wen)度會(hui)影響(xiang)根系(xi)對肥(fei)(fei)料濃度的(de)忍耐力，氣(qi)溫(wen)高時(shi)(shi)，施(shi)(shi)肥(fei)(fei)濃度要低，否(fou)則易(yi)發生燒根。溫(wen)度低時(shi)(shi)濃度要大些，所(suo)以，應根據天(tian)氣(qi)變化(hua)施(shi)(shi)肥(fei)(fei)。

　　4.根據不(bu)同肥(fei)料種(zhong)類(lei)采(cai)取不(bu)同的施(shi)肥(fei)方法在追(zhui)(zhui)施(shi)化肥(fei)時，宜(yi)采(cai)取溝施(shi)，以便集中肥(fei)效(xiao)，追(zhui)(zhui)施(shi)肥(fei)后要及(ji)時覆(fu)土(tu)，防止養分揮發降低肥(fei)效(xiao)，追(zhui)(zhui)肥(fei)氮素化肥(fei)時應(ying)距離植(zhi)株根莖(jing)10厘米(mi)以外，避免燒根。追(zhui)(zhui)肥(fei)時結合灌(guan)水(shui)可提高(gao)肥(fei)效(xiao)。

　　一般(ban)黃(huang)瓜(gua)(gua)和番茄的基肥(fei)(fei)(fei)用量(liang)大致相等。一畝大棚黃(huang)瓜(gua)(gua)、番茄的用肥(fei)(fei)(fei)品種及數量(liang)是：可選用腐熟好的圈糞(fen)3000-4000公(gong)(gong)(gong)(gong)(gong)斤(jin)或阿(a)維菌(jun)素(su)(su)(su)有(you)機(ji)肥(fei)(fei)(fei)520-640公(gong)(gong)(gong)(gong)(gong)斤(jin)（用阿(a)維菌(jun)素(su)(su)(su)有(you)機(ji)肥(fei)(fei)(fei)可不再使用雞(ji)糞(fen)，一般(ban)40-50公(gong)(gong)(gong)(gong)(gong)斤(jin)阿(a)維菌(jun)素(su)(su)(su)有(you)機(ji)肥(fei)(fei)(fei)可代替500-800公(gong)(gong)(gong)(gong)(gong)斤(jin)雞(ji)糞(fen)），磷酸二銨40公(gong)(gong)(gong)(gong)(gong)斤(jin)，純硫(liu)(liu)酸鉀100公(gong)(gong)(gong)(gong)(gong)斤(jin)，尿(niao)素(su)(su)(su)30公(gong)(gong)(gong)(gong)(gong)斤(jin)，印度鈣肥(fei)(fei)(fei)4公(gong)(gong)(gong)(gong)(gong)斤(jin)，硼砂(sha)3公(gong)(gong)(gong)(gong)(gong)斤(jin)，硫(liu)(liu)酸鋅1.5公(gong)(gong)(gong)(gong)(gong)斤(jin)，微生物菌(jun)劑(ji)40公(gong)(gong)(gong)(gong)(gong)斤(jin)。把以(yi)上肥(fei)(fei)(fei)料撒入地表面深翻。微生物菌(jun)劑(ji)可采取(qu)溝施、穴施的方(fang)法，在移栽(zai)時進行集中使用。
