This paper deal with the law of water requirements, irrigation scheduling and variance of yield and sugariness of watermelons through the mini-spray irrigation test. The results of tests show that the yield of watermelons achieves through mini-spray irrigation has increased by 45% in comparison with that achieved through furrow irrigation, And mini-spray irrigation saves half of the water furrow irrigation takes. Watermelons can be sprayed with water three or four times in their growing season. The rated irrigation water amounts to 15-i7m~3/mu. The proper soil water contents are respectively 60-70% at the shoot stage, 60-75% at the spreading stage, 70-80% at the melon-growing stage and 55-65% at the mature stage (soil water capacity is expressed by percentage). The peak water requirements of watermelons are at the melongrowing stage. The daily average amount of water requirments is 5.4mm at this stage. The tests show that mini-spray irrigation for watermelon is a method of saving energy, saving water and high benefit and a method with simple equipment and at easy use.

本文通过西瓜微喷试验,,研究了西瓜的需水规律、灌溉制度以及微喷对西瓜产量和含糖度的影响。试验资料表明;微喷西瓜此沟灌增产45%,省水50%左右,西瓜全生育期可喷水3~4次,灌水定额以15~17m~3/亩为宜。适宜土壤含水率为苗期60~70%,伸蔓期60~75%,结瓜期70~80%,成熟期55~65%(占田持百分数)。西瓜全生育期需水强度高峰值在结瓜期,日平均需水量达5.4mm,此期是灌水关键时期。试验表明,微喷西瓜是一种节水节能、效益高、设备简单、使用方便的灌水方法。

Water stored in the specially-made earthenware pots buried in the soil and covered with plastic mulch slowly penetrates into soil through the micro-apertures on the pot wall and moistens the soil around the root zone. The results showed that this irrigation technique does not cause surface runoff , water loss through deep penetration and prevent soil surface crust. In drought season, it provides efficient supplementary irrigation, and evaporation is minimized by mulching. Furthermore, fertilizers and chemicals...

Water stored in the specially-made earthenware pots buried in the soil and covered with plastic mulch slowly penetrates into soil through the micro-apertures on the pot wall and moistens the soil around the root zone. The results showed that this irrigation technique does not cause surface runoff , water loss through deep penetration and prevent soil surface crust. In drought season, it provides efficient supplementary irrigation, and evaporation is minimized by mulching. Furthermore, fertilizers and chemicals can be added in the irrigation water and transferred to the root zone if necessary. In the mountain areas, with 350 mm annual rainfall, watermelon, seeded watermelon, eggplant, tomato and pepper have been successfully planted by using water stored in the water-harvesting pools. Compared with grain production under mulching, the output increases 3. 5-5. 9 times greater while the input is only about 1/3 of drip irrigation system.

特制陶罐埋入土中盖膜并盛水,通过罐壁微孔,使水分缓慢渗入土中,试验表明,该技术不形成径流和深层水分渗漏,不造成土壤板结,遇旱可及时补水,并将作物需要的养分和农药溶于水中,在地膜覆盖下,很少发生地表蒸发。在年降雨量350mm左右的旱山区,利用“121”雨水集蓄工程中的窖水,种植西瓜、籽瓜、西红柿、辣椒等获得成功,其效益与种植地膜粮食相比,高3.5~9.8倍,而成本仅为软管滴灌的1/3。

In order to reduce ground water level for the purpose of mitigating secondary salinity and enhancing water use efficiency,experiments of drip irrigation for watermelon with saline water were conducted in Hetao Region.Four irrigation treatments were conducted:30%,60% and 90% of evaporation and control,with 1,2,3,and 0 laterals of equal flow rate respectively,in the same period of time and with same frequency.The control was not irrigated throughout the season.The results showed that the watermelon...

In order to reduce ground water level for the purpose of mitigating secondary salinity and enhancing water use efficiency,experiments of drip irrigation for watermelon with saline water were conducted in Hetao Region.Four irrigation treatments were conducted:30%,60% and 90% of evaporation and control,with 1,2,3,and 0 laterals of equal flow rate respectively,in the same period of time and with same frequency.The control was not irrigated throughout the season.The results showed that the watermelon yield was increased and its quality was improved under drip irrigation.The highest increase in yield and dramatic enrichment in Vitamins and Calcium was under the 60% treatment.The water use efficiency for different treatments had basically the same trend.Under drip irrigation,salts were unevenly distributed in the soil profiles.Salts were accumulated in the topsoil layer adjacent to the emitters under the 30% treatment with higher averaged concentration.There was no significant salt accumulation in other treatments.

为了降低内蒙古河套灌区的地下水位、减少盐碱化、提高水的利用效率及增加农民的收入,在长胜试验站进行了西瓜咸水滴灌的适宜性试验研究。本试验采用4种灌溉处理:按蒸发量的30%灌水(一行作物1条滴灌带);按蒸发量的60%灌水(一行作物2条滴灌带);按蒸发量的90%灌水(一行作物3条滴灌带);对照处理:不灌水(传统方法)。各处理的灌溉水质和灌溉时间、灌水次数相同。试验结果表明:用咸水滴灌灌溉的西瓜,与不灌溉的西瓜相比,产量和品质都有较大的提高。两条滴灌带处理的西瓜产量最高,且维生素和钙的含量也比其他处理有很大提高。在咸水滴灌情况下,土壤剖面的盐分分布极不均匀,处理a的表层土壤盐分积累增加,且土壤剖面平均含盐量要明显高于对照处理、处理b和处理c剖面土壤平均盐渍度。各处理距离滴头50cm处各剖面的盐渍度要高于距离滴头10cm处各剖面的盐渍度。处理b和处理c灌溉结束后,土壤剖面的平均盐渍度和灌溉初期相比,基本没有形成土壤盐份的累积。
