秋植蔗具有生长期长、生长量由高到低,再由低到高的特点。这就形成了秋植蔗在吸收肥料方面的特有规律。这个规律大致是:(一)吸肥总量一般要比春植蔗多三至四成。按照春新植蔗地上部(茎叶)收获物一万斤,需吸收20斤氮素来计算,一般秋植蔗约需氮素总量26-28斤。根据云南省甘蔗研究所对秋植蔗不同氮素用量的试验结果也认为:亩施
Autumn sugarcane has a long growing season, growth from high to low, then low to high characteristics. This formed a unique pattern of autumn sugarcane in the absorption of fertilizer. This rule is roughly: (A) the total amount of fat absorption than the spring cane plants generally three to four percent. In accordance with the spring new plant cane to the top (stems and leaves) a kilogram of harvest, need to absorb 20 kg of nitrogen to calculate the general needs of about 28-28 kg of nitrogen fertilizer autumn cane total. According to the sugarcane research institute of yunnan autumn sugarcane different nitrogen dosage test results also think: mushi
