冬季造成“空心果”的直接原因是大棚内浇灌水的温度下降,在低温情况下,西红柿根部受冷紧缩,根须生机下降,吸水性差,如此时植株幼果正处于膨大期,在短期短缺水分供给的情况下,则易涌现局部的果中少肉现象。因此,冬季浇灌大棚西红柿,水温必须预先提高到10℃以上,可利用大棚一角暂存浇灌水,以利提温。加强光照管理生长中后期要恰当打杈和摘叶,加强光照,增进通风。通常是结果枝上果实采摘后,位于其下面的侧枝要及时打掉,以保证坐果
The direct cause of “hollow fruit” in winter is the decrease of the temperature of watering the water in the greenhouse. Under low temperature, the root of the tomato is coldly compressed, the root vigor decreases, and the water absorption is poor. In this case, the young fruit of the plant is in the period of enlargement. Short-term shortage of water supply situation, then prone to local fruit juvenile phenomenon. Therefore, the watering greenhouses tomatoes in winter, the water temperature must be increased to above 10 ℃ in advance, you can use the temporary storage of water shed green corner to Li Ti. To strengthen the light management growth should be appropriate in the late twigs and pick leaves, to enhance light and enhance ventilation. Usually the result after picking the branches of fruit, located below the side branches to be promptly destroyed in order to ensure fruit set
