从一九七六年起我们采用滴水灌溉(简称滴灌)种植西瓜。从两年对西瓜进行滴灌种植的结果表明,滴灌西瓜比沟灌西瓜具有优质高产,节省大量灌溉用水,保持土壤结构,提高土地利用率等许多突出优点。 1.优质高产:一九七六年滴灌西瓜亩产5400斤,一九七七年滴灌西瓜亩产8150斤,都比沟灌西瓜高产。一九七七年增产竟达85.8％。滴灌西瓜品质优良,香甜可口,含糖量高达13％,通过品质鉴定,群众反映滴灌西瓜个大好吃,优质高产。从构成产量因素各性状和考种来看,滴灌西瓜明显优于沟灌西瓜。其情况见表1表2。
Since 1976, we have used drip irrigation (referred to as drip irrigation) to grow watermelons. The results of drip irrigation on watermelon from two years show that drip irrigation watermelon has many outstanding advantages such as high quality and high yield, saving a lot of irrigation water, maintaining soil structure and improving land utilization. 1. High quality and high yield: In 1976 drip irrigation watermelon mu yield 5400 kg, 1977 drip irrigation watermelon 8150 kg per mu, than the irrigation of watermelon high yield. In 1977, it increased production by 85.8%. Drip irrigation watermelon quality, sweet and delicious, sugar content as high as 13%, through the identification of quality, the masses reflect the drip irrigation watermelon a delicious, high quality and high yield. From the characteristics of yield factors and test species, drip irrigation watermelon was significantly better than furrow irrigation watermelon. The situation is shown in Table 1 Table 2.
