3-(4-chlorophenyl)-4-phenyl-4,5-dihydro-1H-pyrazole 2-(chloromethyl)-3-methylpyridinehydrochloride 1-(2-bromo-4-methylphenyl)ethanone 3-chloroisoquinoline-4-carbonitrile 5,8-dichloropyrido[3,2-d]pyridazine 2-bromomalononitrile 2-(4-(bromomethyl)phenyl)benzo[d]thiazole 1-(bromomethyl)-3-methoxy-2-nitrobenzene 6-bromo-1H-[1,2,3]triazolo[4,5-b]pyridine 4-iodo-2-((trimethylsilyloxy)methyl)thiazole 6-iodoimidazo[1,2-a]pyridine-3-carbonitrile 2-(4-chlorophenyl)-2-morpholinoacetonitrile 4-chloro-7H-pyrrolo[2,3-d]pyrimidine 4-chloroisothiazole 5-bromo-6-chloro-1H-indole 7-chloro-3H-imidazo[4,5-b]pyridine ethyl3-(4-formylphenyl)propanoate 2,3-dibromobenzaldehyde 1-(5H-chromeno[2,3-b]pyridin-7-yl)ethanone 5H-chromeno[2,3-b]pyridin-5-one 3-chloroisoquinoline-4-carbaldehyde (E)-2-(3-oxoprop-1-enyl)benzaldehyde methyl4-formyl-3-nitrobenzoate 5,6-dimethoxy-2,2-dimethyl-2,3-dihydro-1H-inden-1-one 1-methylbicyclo[4.1.0]heptan-3-one 3-nitro-4-(trifluoromethoxy)benzaldehyde 2-hydroxyquinoline-6-carbaldehyde 2-nitro-3-(trifluoromethyl)benzaldehyde 1-(2-fluoro-4-methoxyphenyl)propan-2-one tert-butyl3-fluoro-4-oxopiperidine-1-carboxylate tert-butyl3-oxopropylcarbamate 2,2-dimethylcyclohexanone 9H-carbazole-3-carbaldehyde N,N-dimethyl-2-oxoacetamide 2-methylpent-4-yn-2-ol 3-tert-butyl-4-hydroxybenzonitrile 4-bromo-2-tert-butylphenol 1,3-dibutoxypropan-2-ol methyl4-hydroxyquinoline-6-carboxylate methyl3-cyano-4-hydroxybenzoate 4-chloro-6-methoxyquinolin-7-ol 3,4-dihydro-2H-benzo[b][1,4]oxazin-7-ol 2-(2-aminothiazol-5-yl)ethanolhydrochloride (R)-ethyl2-chloropropanoate (S)-4-amino-5-(4,4-dimethylcyclohexylamino)-5-oxopentanoicacid (1s,4s)-4-hydroxycyclohexanecarboxylicacid (S)-2-(tetrahydrofuran-3-yloxy)aceticacid (1S,4R)-1-methyl-4-(prop-1-en-2-yl)cyclohex-2-enol (R)-4-(hydroxymethyl)oxazolidin-2-one (S)-4-(hydroxymethyl)oxazolidin-2-one 化工資訊 近日，山東地區(qū)氣溫變化較大，上周最后溫度達(dá)27度，本周氣溫驟降，山東濟寧金鄉(xiāng)地區(qū)周一、周二天氣陰雨，棉花加工受阻，當(dāng)?shù)孛藁ǚN植時間也因氣溫較低而推遲。
調(diào)查獲悉，濟寧金鄉(xiāng)地區(qū)近期棉花經(jīng)營尚可，部分廠家籽棉收購價格在3.52元/斤(衣分38-39%)，較上周漲0.09元/斤，三級皮棉出廠價在15400元/噸(大包、帶票)，較上周上漲100元/噸，因下游紡織廠剛性需求，近日皮棉出貨較快，庫存壓力不大。
俗話說，“清明前后，點瓜種豆”，又到了一年一度棉花種植的時間。山東濟寧金鄉(xiāng)地區(qū)因大蒜套種需求，棉花種植面積較去年變化不大，當(dāng)?shù)囟嘁誀I養(yǎng)缽種植為主，棉農(nóng)早早做好缽體下種，等待氣候適宜時下缽。但因近期氣溫變化較大，上周氣溫偏高，本周氣溫較低，周一晚降雨，周二仍有陰雨，周三開始，天氣轉(zhuǎn)好，但氣溫仍較低，下半周溫度在6-2攝氏度。棉農(nóng)反映，氣溫較低對對棉苗影響較大，棉田會出現(xiàn)大面積爛種、爛芽、爛根等現(xiàn)象，還會形成弱苗僵苗，生育進程嚴(yán)重滯后。當(dāng)?shù)夭扇I養(yǎng)缽體提前育苗，且下缽后采取地膜覆蓋，對棉苗起到了有效保濕保溫作用，但為了進一步規(guī)避風(fēng)險，當(dāng)?shù)孛藁ㄏ吕彆r間不同程度推遲。
下周始，氣溫回升，天氣預(yù)報當(dāng)?shù)貧鉁卦?-29攝氏度，屆時，當(dāng)?shù)貙⒋笠?guī)模下缽，棉花種植全面展開，預(yù)計4月底或5月初基本結(jié)束。
