1冬春茬黄瓜什么时期播种为好?答:秋冬季节播种过早(8月)的黄瓜,到深冬期间遇连续阴天,植株就会出现早衰现象,如花包头(瓜打顶)、化瓜、根系变成红褐色、吸收养分的毛细根较少、植株生长势降低等。即使施用生长调节剂(喷施碧护,灌生根剂),植株重新进入正常结瓜生长的缓秧期也需要15～20d(天),若遇到阴、雾、雨、雪天,缓秧期更长,而且商品瓜的瓜条短、刺瘤稀、品质下降。经调查,河南、山东、河北等地区针对越冬茬黄瓜播种期过早,其总产量并不是很高的问题,近 1 winter and spring cucumbers at what time sowing is better? A: cucumbers cucumbers planted early in autumn and winter seasons (August), in case of continuous cloudy during the winter, the plant will appear premature aging phenomenon, such as flower Baotou (melon top) Melons, the roots become reddish-brown, capillary root absorption of nutrients less, lower plant growth potential. Even if the application of growth regulators (spraying Bi, irrigation root), the plant re-entry into the normal growth of the slow seedling also need 15 ~ 20d (days), if the encounter yin, fog, rain, snow, A longer period, but the melon short strips of goods, tumor sparse, quality decline. After investigation, Henan, Shandong, Hebei and other regions for cucumber overwintering sowing premature, its total output is not very high, near
