高粱既是人们的粮食,又是牲畜的好饲料和酿酒的主要原料。高粱具有丰富的营养成分,除用于酿酒、食用和做饲料以外,在制糖加工业上也有广阔的用途。扫帚高粱可做扫帚,高粱秆可制成胶合板做建筑材料,可谓一身都是宝。现将其高产栽培技术介绍如下。一、高粱对环境条件的要求(一)温度高粱是喜温作物,在整个生育期间都要求有较高的温度。一定的高温可以提早幼穗分化,低温则可延迟穗分化。这种特性称为高粱的感温性。(二)水分高粱具有抗旱能力强和耐涝性的特点,其耐涝性在孕穗期以后尤为明显。
Sorghum is both a staple of people’s food and a good source of feed and wine for livestock. Sorghum is rich in nutrients, in addition to wine, food and feed, the sugar processing industry also has a wide range of uses. Broom sorghum can be used as a broom, sorghum stalks can be made of plywood building materials, can be described as all are treasure. Now its high-yield cultivation techniques are as follows. First, the requirements of sorghum on environmental conditions (A) Temperature Sorghum is a thermophilic crop, throughout the growing period requires a higher temperature. A certain high temperature can promote spike differentiation and low temperature can delay spike differentiation. This property is called the temperature sensitivity of sorghum. (B) sorghum has the characteristics of drought resistance and waterlogging, its waterlogging resistance is particularly evident after booting stage.
