濟(jì)南曲堤黃瓜
黃瓜在生長期間，如果營養(yǎng)不良，管理不當(dāng)，或遇不良的氣候和某些病害的浸染，往往造成葉片變黃，影響黃瓜的生長，甚至絕收。黃瓜葉片變黃主要有以下三類：
Cucumber in the growth period, if malnutrition, mismanagement, or in case of bad weather and some diseases disseminated, often cause yellow leaves, affecting the growth of cucumber, and even crops. Cucumber leaves yellowing mainly in the following three categories:
缺素型黃葉。缺素型黃葉分為中、下部老葉先黃和中、上部嫩葉先黃兩種情況。中下部老葉先黃，所缺元素多為植株體內(nèi)易被再利用的元素，如氮、鉀、鎂、鋅等。
Deficiency of leaves. Deficiency of leaves into the middle and lower part of the old Ye Xian Huang Hezhong, the first two kinds of yellow leaves in the upper. In the lower part of the old Ye Xian yellow, the missing elements are mostly easy to re-use elements in plants, such as nitrogen, potassium, magnesium, zinc, etc..
1.整個(gè)植株生長受抵制，較老葉片整葉先缺綠，為缺氮。防治對(duì)策是葉面噴施0.5%～1%尿素溶液2～3次。
1 the whole plant growth was resisted, and the whole old leaf was lack of green for Ye Xian. Prevention and control measures are foliar spray 0.5% ~ 1% urea solution for 2 ~ 3 times.
2.整個(gè)植株生長無明顯抵制脈失綠變黃，葉脈間失綠變黃，葉緣為綠色，或殘留有綠色斑點(diǎn)，不卷曲，為缺鎂。防治對(duì)策是葉面噴施1%～2%硫酸鎂溶液。
2 of the whole plant growth without obvious loss of green and yellow veins to resist, chlorosis between veins of yellow, green leaf margin, or residual green spots, not curly, for magnesium deficiency. The preventive measures were spraying 1% to 2% Magnesium Sulfate solution.
3.植株生長無明顯抑制，葉緣失綠以至壞死，有時(shí)葉片上也有失綠至壞死斑點(diǎn)，為缺鉀。防治對(duì)策是葉面噴施0.3%～0.5%磷酸二氫鉀溶液2～3次。
3 no obvious inhibition of plant growth, leaf edge chlorosis and necrosis, sometimes the leaves are also green to necrotic spots, lack of potassium. Prevention is a foliar application of 0.3% ~ 0.5% and 2 ~ 3 potassium dihydrogen phosphate.
