冬暖大棚秋冬茬厚皮甜瓜(洋香瓜)可贮存到元旦、春节上市,经济效益较高。但秋冬茬在山东育苗期正处在7月至8月初的炎夏季节。此季节光照过强,温度过高,降雨量多,枯萎病、蔓枯病、病毒病、蚜虫等病虫害严重。10～11月份果实正处于膨大期及成熟期,此时气温下降,天气日渐寒冷,而甜瓜在膨大期和成熟期要求较高的温度、较强的光照和较大的昼夜温差。因此,秋冬茬栽培厚皮甜瓜有一定难度,管理不当会造成苗期多病,后期果实畸形,着色不良,导致减产或绝产。根据这种情况,应选用抗病性强、生育期短、成熟快的品种或选用中熟、抗病性好、后期耐低温兼
Winter warm shed autumn and winter stubble melon (melon) can be stored until New Year’s Day, the Spring Festival listing, high economic returns. However, autumn and winter stubble in Shandong breeding period is at the early summer of July to early August. This season the light is too strong, the temperature is too high, rainfall, blight, vine disease, virus disease, aphids and other pests and diseases serious. From October to November, the fruit is in the period of enlargement and maturity. At this moment, the temperature drops and the weather is getting colder. The muskmelons require higher temperature, stronger light and larger day-night temperature difference in swollen and mature periods. Therefore, autumn and winter cultivation of muskmelon melons have some difficulty, improper management will result in sick seedling stage, the late fruit malformations, poor coloring, resulting in reduced production or abortion. According to this situation, we should choose the disease-resistant, short growth period, mature varieties or use maturity, good disease resistance, low temperature and late
