日光温室厚皮甜瓜连年种植,连茬障碍逐年增加、病害加重、产量降低。嫁接后可以连年种植,较好的抑制枯萎病的发生,在不降低品质的基础上,产量较不嫁接的增产10—15%,同时由于嫁接后抗寒性增强,可以提早播种,提早结瓜,增加前期产量,一般亩产2000—2500千克。主要栽培技术如下:一、嫁接1、砧木选择。砧木选择应符合下列条件:(1)与接穗有良好的亲和性。(2)低温状况下根系发育正常。
The sunlight greenhouse thick-skinned muskmelon planted year after year, crop stubble increased year by year, disease increased, the yield decreased. After grafting can be planted year after year, the better suppression of the occurrence of blight, without reducing the quality of the foundation, the yield is not grafted 10-15% yield increase, and due to increased cold tolerance after grafting, early sowing, early knot , Increase pre-production, generally 2000-2500 kg per mu. The main cultivation techniques are as follows: First, grafting 1, stock selection. Rootstock selection should meet the following conditions: (1) has a good affinity with the scion. (2) Normal root development at low temperature.
