摘要
山区农业在农业生产中占有较大比重,但山区耕地分布不连片且不易进行集约化开发,导致长期以来山区农业粮食产量低。利用机动灵活的光伏提水灌溉是改变现有低效生产的重要途径,而蓄水池是光伏提水灌溉的重要组成部分。通过分析作物需水量、太阳能资源,确定光伏提水系统、田间灌溉系统各项参数。利用Origin软件对水泵流量—时间曲线、蓄水池水量—时间曲线进行模拟,计算出容积为16.44 m^3的蓄水池即可满足典型农户1.52 hm^2青储玉米的滴灌要求。
Mountain area agriculture is an important part of ensuring food security in our country,which also occupies a large proportion in agricultural production. The uneven distribution of cultivated land in mountainous areas result in the agricultural production deeply dependence on the climate and poor food crops. Using the photovoltaic pumping irrigation system( which is mobile and flexible) is an important way to change the situation,While the reservoir is an important part of photovoltaic pumping irrigation system. The pump flow-time curve,reservoir-time curve were simulated through using the Origin software by analyzing the crop water requirement,solar energy resources the photovoltaic pumping system and the field irrigation system. It is calculated that 16.44 m3 of reservoir can meet the 1.52 hm2 corn silage requirement which belong to a typical farmhouses.
