棉花在其生长和发育的过程中,灌溉对提高棉花产量起着显著的作用,如石家庄专署灌溉管理处1952—1955年在石家庄、获鹿、藁城和晋县等地调查,灌水比不灌的棉花可增产16——233%,我所1957年灌水较不灌水的产量提高68%。要想把地浇好,必须讲究灌溉技术,实行科学合理的灌溉。实行合理的灌溉,首先应当掌握棉花在各个不同的生育时期对水分的要求,并且要把所需要的水量,适时而又准确地送到棉田里,浇地必须与各种
During the growth and development of cotton, irrigation played a significant role in increasing cotton yield. For example, the irrigation department of Shijiazhuang Administration surveyed Shijiazhuang, Shilu, Tancheng and Jinxian from 1952 to 1955, Of the cotton production can be increased by 16--233%. In 1957, the yield of less irrigated and less-irrigated crops increased by 68%. To cast the ground well, we must pay attention to irrigation technology, the implementation of scientific and rational irrigation. In order to implement proper irrigation, we must first grasp the moisture requirements of cotton at different growth stages and send the required amount of water to the cotton fields timely and accurately.
