我们沙包乡共有423076株苹果树,其中结果树212296株。这些树均栽植在土质瘠薄的山坡地上,由于土壤中硼素缺乏(在0.3ppm以下),苹果产量不高,质量低劣。近几年我们注意给果树施硼,平均每年用硼砂10余吨,相继给18万余株结果树施了硼(占结果树总数的81.8％),使树势得到恢复,苹果产、质量有了很大提高,年增产苹果400万斤,增加产值60余万元。施硼后,果树枝叶得以正常生长,而且叶色浓绿,叶片变厚百叶重增加,从而有利于花芽形成和果个增大,可使一等果增加40％,增产12.9％。另外,喷硼比未喷硼花序座果率提高42％。
There are altogether 423 076 apple trees in Sha Baoxiang, of which 212296 are result trees. These trees are planted on infertile hillsides, and because of the lack of boron in the soil (below 0.3ppm), the yield of apples is low and their quality is poor. In recent years, we pay attention to the application of boron fruit trees, with an average of more than 10 tons of borax each year, have been given more than 180,000 results of the tree boron (81.8% of the total number of fruit trees), so that the tree potential to be restored, apple production, quality A great increase, the annual increase of 4 million pounds of apples, an increase of output value of more than 60 million. After the boron application, the fruit tree branches and leaves can grow normally, and the leaf color is dark green, the leaf thickens and increases the weight of the leaf, which is beneficial to the formation of flower buds and the increase of the fruit, which can increase the first-class fruit by 40% and increase the yield by 12.9%. In addition, the rate of fruit boring by spraying boron was 42% higher than that without spraying boron.
