Yield grading and yield increasing measures of safflower in Xinjiang
Using the data of safflower grain yield in China and the world downloaded from the official website of the Food and Agricul-ture Organization of the United Nations,the growth index,yield and effect of increasing measures of safflower in Xinjiang were investi-gated by means of literature integration analysis.The results showed that the average plant height,stem thickness,branch height,and fruit ball diameter of Xinjiang safflower were 88.97,1.58,36.45,2.50 cm,respectively.The average number of fruit balls per plant was 15.71,the average thousand grain weight was 43.61 g,and the filament yield was 152.00～1 350.00 kg/hm2,with an average value of 421.06 kg/hm2.The grain yield was 540.00～2 913.00 kg/hm2,with an average value of 1 699.35 kg/hm2.The correlation analysis showed that there were varying degrees of correlation between safflower silk yield and various growth indicators,and there was no sig-nificant correlation between grain yield.The average global and Chinese safflower grain yields from 2016 to 2021 were 949.4 kg/hm2 and 1 458.5 kg/hm2,respectively.Grain yields above 1 800 kg/hm2 were used as high-yield fields,1 350～1 800 kg/hm2 were used as medium high-yield fields,900～1 350 kg/hm2 were used as middle yield fields,and below 900 kg/hm2 were used as low yield fields.Reasonable measures such as dense planting,irrigation and fertilization could all increase safflower yield.Properly increasing planting density could increase yield by 31%to 54%,reasonable irrigation could increase yield by 33%to 92%,and reasonable fertilization could increase yield by about 1 times.The yield variation of safflower in Xinjiang was large,so it was necessary to further explore the cultivation technology system for the high and stable yield of safflower.
