硅肥最早在南方的水稻和甘蔗上得到广泛应用,可以增加产量,提高品质,增强作物的抗病、抗倒伏能力。我市土壤有效硅普遍偏低。据山东省土肥站对183个土壤样品的分析,我市土壤有效硅含量的最小值为35.6mg/kg,最大值为345.0mg/kg,平均值为172.0mg/kg。为了探讨硅肥对苹果树营养生长的影响,1999年冬我们在牟平区大窑镇新福村进行了苹果硅肥试验,现将结果报告如下。
Silicate fertilizer is widely used in rice and sugarcane in the south for the first time, which can increase yield, improve quality and enhance disease resistance and lodging resistance of crops. The effective silicon in our city is generally low. According to the analysis of 183 soil samples from the soil fertility station in Shandong Province, the minimum effective soil silicon content in our city is 35.6 mg / kg and the maximum is 345.0 mg / kg, with an average value of 172.0 mg / kg. In order to investigate the effect of silicon fertilizer on the vegetative growth of apple trees, in the winter of 1999 we conducted the apple silicon fertilizer test in Xinfu Village, Dayao Town, Muping District, and the results are reported as follows.
