土壤水分的测定,对于灌溉管理部门执行计划用水,指导作物适时适量灌水,在进行面大、点多、量少且要及时的测报土壤墒情,以及适应农业生产群众性科学实验开展的需要等时,由于专门设备缺乏,一般标准的烘箱法,常不能满足需要.在没有电热烘箱的条件下,1958年,我们曾在农村基点和个别渠道管理处试用薄铁皮上铺士或砂,就灶火口烘土样.经1959年站内初步鉴定,1960年又专门做了研究,认为效果尚好.此后即在全专区11个渠道得到推广.
The determination of soil moisture, the implementation of the planned irrigation water management department, to guide timely and appropriate irrigation of crops, in the face of large, more, less and timely soil moisture measurement, and to adapt to agricultural production mass scientific experiments to carry out the needs of other , Due to the lack of specialized equipment, the general standard oven method often can not meet the need.In the absence of electric oven under the conditions of 1958, we have in the rural areas and individual channel management office trial thin sheet metal on the shop or sand, on the stove burner mouth Baking soil samples .1993 preliminary identification of the station, 1960 and a special study done, that the effect is good. Since then in the entire area 11 channels to be promoted.
