钙硫肥即硫酸钙。分为普通硫酸钙和雪花硫酸钙。普通硫酸钙呈白色或灰白色粉末,含有结晶水,能溶于水,但溶解度不大。多元微肥,具有使作物叶色发绿,分枝粗壮,根瘤增大,提高花生百粒重增加双粒果,并有提前成熟,增强抗病、抗旱能力,促进新陈代谢,提高光合效率,增加干物质积累,改善品质的作用。1988年我们在本县熊寨乡刘大塘村的春播花生田,安排了五处田间小区对比试验,并在该村花生、玉米田各2000亩进行了大田示范。试验是在花生、玉米播种时,以每亩25公斤钙硫肥为基肥,多元微肥拌种,在花生苗期、始花期、结荚期各喷一次多元微肥水溶液。结果表明,在当年久旱无雨条件下,花生、玉米获得丰
Calcium Sulfate is calcium sulfate. Divided into ordinary calcium sulfate and snowflake calcium sulfate. Ordinary calcium sulfate was white or off-white powder, containing water of crystallization, soluble in water, but solubility is not large. Multi-element fertilizer, with crop leaf color hair green, branches stout, nodules increased, increased peanut 100 grain weight increase double fruit, and have matured in advance, enhance disease resistance, drought resistance, promote metabolism, improve photosynthetic efficiency, increase Dry matter accumulation, improve the quality of the role. In 1988, we arranged springfield sowing peanut fields in Liu Datang Village, Xiongzhai Township, Xicheng County, and arranged comparative experiments on five field plots. Field demonstration was conducted in 2000 mu of peanut fields and corn fields of the village. The experiment is in peanut, corn sowing, with 25 kg of calcium and sulfur fertilizer per acre as base fertilizer, multivariate fertilizer dressing, at the peanut seedling stage, the initial flowering, podding spray multiple multivariate fertilizer solution. The results showed that peanuts and corn gained abundance under the conditions of arid and rainy years
