从纤维增长说起前不久,我们到白浪生产队去,正赶上社员们收摘棉花,老农张永福种的两亩四分棉花,纤维长度竟比别人种的增长了六毫米。这是怎么一回事呢?噢!原来他在棉田里施了钾肥。钾肥和氮肥、磷肥一样,对庄稼的作用可大着呢!据有关部门的统计,含氧化钾一斤的钾肥可增产粮食2.8—2.7斤,增产白薯33斤,增产花生7.1斤,增产棉籽1.9斤,增产黄麻4.l斤。合理地施用钾肥,可以使水稻含米量增加3%,薯类淀粉含量提高2.1%,菜子含油量提高5%,棉花纤维长度不仅增长,而且细度提高和成熟期早,黄麻拉力可提高3.l%。钾肥还可以提高甘蔗的含糖率,改善烟草质量,促使农作物根须发达,增加抗旱力和增强对病虫害的抵抗力等。此外,钾肥还可促使农作物茎杆健壮,不易倒伏,这对水稻高产,尤为重要。
Speaking from the fiber growth Not long ago, we went to the White Wave Production Team to catch up with the members of the cotton harvest, farmer Zhang Yong-bred two-acre cotton, fiber length than any other kind of growth of six millimeters. What’s going on? Oh! It turned out he had potash fertilizer in the cotton fields. According to the statistics of related departments, the potash fertilizer containing potassium pound of one kilogram can increase the grain output by 2.8-2.7 kg, increase the yield of sweet potato by 33 kg, increase the output of peanut by 7.1 kg and increase the yield of cottonseed by 1.9 kg , 4.l kg jute increase. Reasonable application of potash fertilizer can increase rice content by 3%, potato starch content by 2.1% and rapeseed oil content by 5%, and the cotton fiber length not only increases but also the fineness and early maturity can increase by 3 .l%. Potassium fertilizer can also improve the sugar content of sugarcane, improve tobacco quality, promote crop root development, increase drought resistance and enhance resistance to pests and diseases. In addition, potash fertilizer can also promote robust stems of crops, not easy to lodging, which is high yield of rice is particularly important.
