发展大棚早熟西瓜,嫁接技术是决定其产量和效益的重要因素,它可有效防止枯萎病,抗冻、高产、早熟。西瓜嫁接主要有靠接和插接两种办法。实践证明,插接法较为简单、易学。一、建造育苗棚。插接法嫁接西瓜,需利用日光温室,采取室内升温的方法。因此,搞好西瓜嫁接必须建造育苗棚,比较理想的是建在通风透光的大田地。育苗棚的式样大体与日光温室相同。苗棚后墙高1.5米、厚0.5米,山墙最高处2.0米,棚长根据需要决定。时间宜在11月1日～15日。二、整苗畦。苗畦一般宽1～1.2米,畦面要低于地面11～12厘米,畦内要整平、压实。时间宜在12月20日～25日。三、装营养袋。营养袋须先用无底
Development of greenhouse precocious watermelon, grafting technology is an important factor in determining the yield and benefits, it can effectively prevent the blight, frost, high yield, early maturity. Watermelon grafting mainly docking and plug two ways. Practice has proved that plug-in method is relatively simple, easy to learn. First, build nursery shed. Docking method grafted watermelon, the need to use solar greenhouse, indoor heating method. Therefore, to do a good job of grafting watermelon nursery shed construction, the ideal is built in the field of light and light field. The nursery shed is roughly the same in style as the solar greenhouse. Miaopeng after the wall 1.5 meters high, 0.5 meters thick, the highest point of 2.0 meters gable, shed long according to need to decide. Time should be November 1 to 15. Second, the whole seedlings. Seedlings generally 1 to 1.2 meters wide, noodles to be lower than the ground 11 to 12 cm, inside to be leveling, compaction. Time should be December 20 ~ 25. Third, install nutrition bags. Nutrition bags must first use bottomless
