亚硫酸氢钠在粮食作物上的应用已有报道,它是通过抑制光呼吸来增加作物养分的积累提高产量和品质的。然而在柑桔上的应用未见报道,为了探明光呼吸抑制剂亚硫酸氢钠对柑桔抗寒防冻、促花保果、提高产量和品质的效应,我们进行了柑桔不同时期喷施亚硫酸氢钠的试验,现将结果报告如下: 一、材料和方法 试验设在兰塘乡桥头村江塘山密植桔园,供试植株为三年枳砧椪柑,试验自1986年12月至1987年12月止。 供试材料为上海试剂四厂生产的亚硫酸氢钠(NaHSO_3),分析纯,SO_2含量为58.5～65.0％。
The use of sodium bisulfite in food crops has been reported to increase yield and quality by increasing the accumulation of crop nutrients by inhibiting photorespiration. However, the application on citrus has not been reported. In order to find out the effect of photoresponsive sodium bisulfite on the anti-freezing and antifreeze of citrus, promoting the flower and fruit preservation and improving the yield and quality, we carried out the spraying of citrus at different times Sodium bisulfite test, the results are reported as follows: First, the material and method test is located in Qiantou Village, Qiaotou Village, Lantang Township, dense orange plantation, the test plant for three years orange lotus root ankle root test from December 1986 to December December 1987 only. The test materials were sodium bisulfite (NaHSO_3) produced by Shanghai Reagent Factory No. 4, with an analytical purity of 58.5-65.0%.
