在干旱地区,除其它措施外,生产中栽培耐旱而高产的作物对加强饲料基地有着很大的意义。高粱是这类作物之一,它的用途很广,并且家畜和家禽都很爱吃。无机肥料包括微量元素肥料,可提高高粱的产量。美国和印度对此问题进行了很有意义的研究。美国乔治亚州科研机关.在控制条件下(水培和砂培)研究了锰对粒用高粱生长的影响及缺锰症状。在锰浓度为0～4000毫克/升的营养液中培养植株,当锰不足(低于50毫克/升)时植株生长缓慢,出现明
Among arid areas, among other measures, the cultivation of drought-tolerant and high-yield crops in production is of great importance to the strengthening of feed bases. Sorghum is one of these crops, its use is very wide, and both livestock and poultry love. Inorganic fertilizers, including trace element fertilizers, increase sorghum production. The United States and India conducted a very meaningful study on this issue. Research institutions in Georgia, USA studied the effects of manganese on grain sorghum growth and manganese deficiency under controlled conditions (hydroponics and sand culture). Plants are grown in nutrient solutions with Mn concentrations from 0 to 4,000 mg / l. Plants grow slowly when Mn is deficient (less than 50 mg / l)
