Measurement and Analysis of Saccharum Saccharum Saccharum by Sugar Analyzer As early as the 1960s, stilts began to be used as animal feed. According to the Food and Agriculture Organization of the United Nations (FAO), in 1995, about 96% of sorghum in developed countries had been used for animal husbandry. As animal feed, sorghum can be used for grazing, hay or silage. Increasing sugar content in sorghum stalks can increase feed palatability and improve feed quality. With the improvement of the living standards of our people, animal husbandry will inevitably have a long-term development. Studying the change rule of sugar content in sorghum stalk will provide theoretical basis for cultivating sorghum high sugar content varieties and timely use. 1 Materials and Methods A high-sugar parental inbred line 1095 and a low-sugar parental inbred line N3 were crossed to obtain isolated population F2 (205 strains). The two parental inbred lines 1095 and N3 were sowed in the experimental field in spring, and each material was planted in 10 rows of 15 plants each with 2 replicates. After heading and flowering (85 days after sowing), every 7 days, the sugar content (Brix value) in the middle of each internode of the whole plant was measured with a sugar meter. Each time, 10 lines were taken in the middle and the sugar meter was used. Measured six times. In addition, the F2 population (205 strains) was sowed in the experimental field in summer, and the inter-tree sugar content (Brix value) of each plant in the population was measured at the beginning of wax ripening. The resulting data were plotted by Excel processing to analyze various changes in sugar content. 2 Results and Analysis 2.1 Changes in Sugar Content at Different Growth Stages From the time of heading, the sugar content in the stalk was measured until a peak appeared, and then decreased until the sugar content of the sorghum stalk in the whole growth period was analyzed. The results showed (Fig. 1) that the sugar content in the stalk was relatively low during the period from the earliest stage of flowering and flowering to the full flowering stage, and then gradually increased. The sugar content rose rapidly from the early stage of milk ripening to the initial stage of wax ripening, and it was at the early stage of wax ripening. The highest sugar content, then began to decline. The variation of sugar content was consistent with the performance of the high sugar parent inbred line 1095 and the low sugar parent inbred N3. Considering the sugar content, wax ripening is the best time for the whole plant of Sorghum. 2.2 Changes in sugar content in different nodes For high glucose 1095, a total of 7 internodes, the highest value of sugar content in the 4 periods out of the 6 measurement periods occurred in the first internode, and the 2 interphases were in the internodes. The highest sugar content (Table 1). The case of the low-sugar N3 is slightly different from that of the high-sugar 1095. There were 6 internodes in the parent N3, 4 of the 6 measurement periods had the highest sugar content in the first internodes, g periods (106 days) were the highest sugar content in the internodes, and the other was 99 days. ) is the highest sugar content in the first quarter. Based on this, the authors believe that the highest sugar content in sorghum stalk should be between the middle internodes or the upper one, which will provide a theoretical basis for accurate determination of sugar content in sorghum stalks. 2.3 Changes in sugar content in F2 population The distribution of sugar content in the population was 6.3% to 16.1%, with a normal distribution. Based on this, it can be considered that the sugar content of sorghum stalk should be a quantitative trait. In the analysis of QTLs for sorghum stalk sugar content (reported elsewhere), the authors identified four QTLs that are located in three linkage groups: C, D, and H. 3 Discussion 3.1 Ikegaya F et al. used 10 sorghum varieties to study the variation of sugar content in sorghum stalks at different growth stages and between different nodes. The results are consistent with the present study. This also shows that, whether it is inbred lines or hybrids, the variation of sugar content in sorghum stalks is the same. 3.2 For sorghum or silage sorghum, it is necessary to have higher stem and leaf yields, and higher grain yield, and the stalks must have higher sugar content, so the harvest is appropriate for silage or Green feeding is very important. According to the present study, the highest sugar content in sorghum stalks is at the beginning of wax ripening, and during this period, the grain yield and stem and leaf yields are already high, so the author believes that wax waxing can be harvested as silage or sorghum This period is basically consistent with Song Renben's point of view. 3.3 The development of forage sorghum production where there is a lack of water resources, droughts, and poor soils all year round will play a significant role in the development of local livestock husbandry and improvement of people’s living standards. Sorghum is used as a silage or green feeding. Because of its good regenerability, sometimes the biological yield is higher than that of corn. According to another report, the use of sweet sorghum to feed dairy cows is more effective than corn, and milk production can increase by about 4.3% to 10.1%. In the United States, about 4 million hm2 are grown in sorghum, but China currently has only 1.4 million hm2. To make further development of feed sorghum production in China, it is necessary to cultivate excellent feed sorghum varieties.
