喷灌(人工降雨)是现代较完善的一种灌水方法。为了适应深翻、密植、多肥等新的农业技术条件下的灌溉问题,我局职工在上级党委支持与领导下,以敢想、敢说、敢干的共产主义风格,先后创制与改制了自然水头、高架提水、人力压水机、水轮泵等以土为主,多种多样,土洋结合的喷灌工具。在生产实践中,初步显示了它的优越性是:在合理的降雨强度下,可保持良好的土壤团粒结构,地面不板结,保墒性能良好;能控制小定额用水,灌水定额为每亩3—15立方米,可随时按照作物需要来补充天然雨量不足,具有很大灵活性,喷灌不仅湿润土壤,而且调节小气候,还能在炎天进行凉爽灌溉;不流失肥料,因而有
Sprinkler irrigation (artificial rainfall) is a more modern irrigation method. In order to meet the irrigation problems under the new agricultural technology conditions such as deep plowing, close planting and more fertilizer, under the support and leadership of higher party committees, our employees have successively created and transformed the system of communism with dare to think, dare to say and dare to do something Natural head, elevated lift, human pressure water machine, water pump and other soil-based, a wide range of soil and water combination of sprinkler tools. In production practice, preliminary shows its superiority is: under reasonable rainfall intensity, can maintain good soil aggregate structure, the ground does not form knot, good soil moisture; can control the small fixed amount of water, irrigation quota of 3- 15 cubic meters, at any time in accordance with crop needs to supplement the lack of natural rainfall, with great flexibility, sprinkler not only moist soil, but also regulate the microclimate, but also in the hot days of cool irrigation; not losing fertilizer, which has
