为提高小麦产量,1977年我们开展了群众性的氯化钙闷种防御干热风的试验,取得了显著效果。据全区11个县42个点700亩试验、示范结果,不论水地旱地,不论品种,都表现增产。一般增产11％左右,高的达15％。安平县南王庄大队在144亩小麦上应用,每亩增产26—36.7斤。小麦增产的原因,据河北农大研究分析,主要是闷种后使细胞内钙离子(Ca~(++))的浓度增加,从而提高了细胞原生质的粘滞度和弹性,增加了渗透结合水的数量,提高了
In 1977, we carried out the test of mass-based calcium chloride prevention and cure against dry and hot winds to achieve a significant increase in wheat yield. According to the 11 counties in the region 42 points 700 acres of experiments, demonstration results, regardless of dry land, regardless of species, have shown increased production. The general increase of about 11%, up to 15%. Anping Nanwangzhuang brigade in 144 acres of wheat application, yield 26-36.7 kg per mu. The reason for the increase of wheat production is that according to the research and analysis of Hebei Agricultural University, the concentration of intracellular calcium ion (Ca ~ (++)) is mainly increased after bored planting, thereby improving the viscosity and elasticity of cell protoplasm and increasing the osmosis combined water The number increased
