Effects of Different Planting Densities and Plastic Film Mulching on the Main Agronomic Traits and Quality of Safflower(Carthamus tinctorius L.)
摘要
Abstract
To explore the effects of different planting densities and different plastic film mulching on the main agronomic traits and quality ofsafflower(Carthamus tinctorius L.),and to provide a theoretical basis for achieving high yield ofsafflowerin arid and semi-arid regions.Taking the safflower variety"Yunhong No.7"as the test material,the main agronomic traits and quality of safflower were determined under different planting densities(A1,8000 plants•667m-2;A2,10000plants•667m-2;A3,12000 plants•667m-2)and different plastic filmmulching treatments(B1,black plastic film;B2,transparent plastic film;B3,no film mulching).The results showed that:stem diameter,number of primary effective branches,and number of secondary effective branches performed the best under density A1,all significantly superior to treatment A3;plant height,branching height,and number of tertiary effective branches were the best under density A3,showing no significant differences from the other density treatments.Except for the diameter of the main capitulum,all other agronomic traits performed optimally under B1 plastic film mulching,most of which were significantly better than B3(no film mulching)treatment.Plot seed yield,number of seeds per capitulum,and 1000-seed weight reached the optimal level under density A3,with some traits showing significant differences from other density treatments.Plot seed yield,number of seeds per capitulum,1000-seed weight,and seed yield per plant were the best under B2 film mulching treatment,and some traits had significant differences from other plastic film treatments.Plot petal yield under the A2×B1 interaction was significantly higher than that of other treatments.Different density and film mulching treatments had no significant effect on safflower quality.Taking yield traits as the core basis for selecting the optimal treatments,A3B2 treatment is preferred in main seed-producing areas,while A2B1 treatment is preferred in main petal-producing areas.Combined with the agronomic traits and quality performance of the safflower variety"Yunhong No.7",in the Yunnan producing areas where safflower petals serve as the main economic value,the optimal planting density and film mulching method are:10000 plants•667m-2 with black plastic film mulching.关键词
