| Camellia oleifera Abel.is an important economic forest tree species in China,and it is one of the four major woody oil plants in the world,camellia oil is its main product and is known as "Oriental Olive Oil",has high medicinal value and edible value.In order to promote the development of Camellia oleifera industry,improve the yield and quality of Camellia oleifera,and achieve high yield efficiently,In this study,different types and amounts of fertilization were used to study the growth,flower bud differentiation and fruit quality of Camellia oleifera,and the results are as follows:(1)Experiment for shoot-promoting fertilizer: Analysis of spring shoot length and spring shoot amount found,all treatments can promote the spring shoot growth of Camellia oleifera.The fertilizer formula is: 240 g of high-concentration pure sulfur-based compound fertilizer(15-15-15)+ 160 g of gurea treatment significantly promotes spring shoot growth,the average amount of spring shoots per plant was 206.33,and the average length of spring shoots was 26.93 cm.Followed by: 200 g of high-concentration pure sulfur-based compound fertilizer(15-15-15)+ 50 g of urea,the average amount of spring shoots per plant was 195.67,and the average length of spring shoots was 24.07 cm.In actual production,it is necessary to scientifically control the amount of fertilization.In this study,it is recommended to choose 200 g of high-concentration pure sulfur-based compound fertilizer(15-15-15)+ 50 g of urea as the shoot-promoting fertilizer formula.(2)Experiment for flower-promoting fertilizer: Analysis of the amount of flower found that each treatment promoted flower bud differentiation of Camellia oleifera,Among them,the two most significant formulas for promoting flower bud differentiation are: 200 g of high-concentration pure sulfur-based compound fertilizer(15-15-15)and 250 g of high-concentration pure sulfur-based compound fertilizer(15-15-15)+ 15 g of potassium dihydrogen phosphate,the average number of flower was 55.1 and 57.43,respectively.And spraying fertilization is better than trenching fertilization about fertilizing potassium dihydrogen phosphate.In summary,the above two groups of fertilizer formulas with significant flower promotion effects can be selected as flower-promoting fertilizerformula of Camellia oleifera.You can try 250 g of high concentration pure sulfur-based compound fertilizer(15-15-15)+ 0.3 % potassium dihydrogen phosphate as flower-promoting fertilizer formula of Camellia oleifera.(3)Experiment for strong fruit fertilizer:(1)The single fruit weight of Camellia oleifera was analyzed,and it was found that each treatment had a certain promotion effect on the single fruit weight of Camellia oleifera.Among them,the fertilizer formula is: the treatment of 300 g of high-concentration pure sulfur-based compound fertilizer(15-15-15)+ 15 g of potassium dihydrogen phosphate has the highest promotion effect on single fruit weight,the average value is 0.49 times higher than the control,and the average single fruit weight is 18.87 g.The second fertilizer formula is: 300 g of potassium sulfate-type nitrate nitrogen-containing compound fertilizer(17-17-17)+ 15 g of potassium dihydrogen phosphate,the average value is 0.47 times higher than the control,and the average single fruit weight is 18.58 g.It can be seen that the fertilization formula of 300 g of compound fertilizer + 15 g of potassium dihydrogen phosphate can effectively promote the single fruit weight of Camellia oleifera.(2)Analysis of the seeding rate of Camellia oleifera found that each treatment had a certain promotion effect on the seeding rate of Camellia oleifera.Among them,the fertilizer formula was: 300 g of high-concentration pure sulfur-based compound fertilizer(15-15-15)treatment had the highest promotion effect on the seeding rate of Camellia oleifera,the average value is 0.22 times higher than the control,and the average seeding rate was 18.22 %.(3)The analysis of the kernel rate of Camellia oleifera found that each treatment had a certain promotion effect on the kernel rate of Camellia oleifera.Among them,200 g of potassium sulfate-type nitrate nitrogen-containing compound fertilizer(17-17-17),200 g of potassium sulfate-type nitrate nitrogen-containing compound fertilizer(17-17-17)+ 15 g of potassium dihydrogen phosphate and 300 g potassium sulfate-type nitrate nitrogen-containing compound fertilizer(17-17-17)+ 15 g of potassium dihydrogen phosphate of fertilizer formula have a higher promotion effect on the kernel rate of Camellia oleifera.The average value is 0.13 times higher than the control,the average kernel rate is 66.84 %,66.75 % and 66.51 % respectively.Synthesis of the above test results,the treatment of 300 g of potassium sulfate-type nitrate nitrogen-containing compound fertilizer(17-17-17)+ 15 g of Potassium dihydrogen phosphate can increase the single fruit weight and kernel yield of Camellia oleifera effectively,it is recommended to use this formula in production as a strong fruit fertilizer of Camellia oleifera. |
