| As a kind of new farmland landscape,rice field painting is to form the agricultural landscape with different patterms or pictures with different color rice in rice field.At present,rice,as a food crop,has also added many new functions on the basis of satisfying peopleundefineds consumption.Rice paddy painting,which combines art and agriculture organically,is widely used.However,in the actual production process of paddy field painting,the technical data of paddy field painting design and field production are not clear,which impact the practical application affect of paddy field painting.Therefore,this research focuses on the design of paddy field paintings and the production of colored rice paddy field paintings,and the research results will provide technical support for the promotion and application of paddy field paintings.In this study,different color rice was used to draw the logo of Yunnan university in the field.We choose the 11 kinds of existing color rice in our project team which were named Yucai 1,Yucai 2,Yucai 3,Yucai 4,Huangye 1.Huangye 2,Huangye 3,Yujing 24,Qianziye 1,Qianziye 2 and Gaozi.Those rise were preliminarily analyzed and screened in Jiajin base of Yuxi academy of agricultural sciences from march to October,2018.Color rice was selected for field experiments,and the varieties suitable for making paddy paintings were selected according to growth period,plant height,leaf color,tillers and other characters.Taking the logo of Yunnan university as the object,using the concept of gardening landscape design,using Photoshop,CAD and Master Sketch and other software to assist in the production and design of Yunnan university’s logo rice field paintings.After the colored rice seedling is sown and raised,the design drawing is made according to the designed rice field drawing with the logo of Yunnan university,and the rice field drawing with the logo of Yunnan university is made by transplanting different colored rice at fixed points in the laying-out method.The research results are as follows:1、The design of Rice field planting should follow the principles of environmental adaptability,ecology,ornamental and practicability.The method of landscape design and the practice of rice planting were adopted.In this study,rice field planting of Yunnan university logo is designed as a left and right symmetrical patterm,we use the building which named Huizelou for artistic design,nine sections and yellow windows are selected to represent the vitality of yunnan university after more than 90 years.According to planting distance,planting design is divided into upper,middle and lower parts.The upper part(1-11 rows)was 3.3m in total,and the plant spacing of the rice was 0.18*0.3m.The middle part(lines 12-90)was 11.7m in total,and the plant spacing of the rice was 0.18*0.15m.The lower part(92-119 rows)is 5.4m in total,and the plant spacing of the rice is 0.18*0.2m.Calculate the planting type and quantity per row according to the design drawing.2、The best ormamental period and suitable rice varieties for rice flield drawing of the logo by Yunnan university was choosed according to plant height,growth period,tillering and leaf color,it can be divided into three ornamental periods:In the first ornamental period,between June 21 solstice and July 1,the plant heights of Qianziye 2,Huangye 1 and Yucai 3 were not significantly different,and the plant heights were basically the same.Therefore,Qianziye 2,Huangye 1 and Yucai 3 should be selected as the planting varieties in the paddy field.During the ornamental period of 2 from July 5 to July 15,there was no significant difference in plant height between Yucai 3 and Huangye 3,and the plant height was basically the same.Therefore,Huangye 3 and Yucai 3 should be selected as the painted planting varieties in the rice field.During the ornamental period of 3 from August 2 to August 12?there were no purple rice varieties with the same plant height as Huangye 3.Qianziye 2,Yucai 3 and Huangye 3,which had no difference in plant height,could be selected for planting.Based on the above three periods,the Yucai 3 and Huangye 3,which can be viewed for a long period,can be selected for paddy painting production.The best viewing period is July 5,solstice,August 7,namely the viewing period is 2.3、The management and collocation of different varieties in the production of rice paintings.In the growth period of rice field painting,the growth period of Huangye 1 was only 174 days,and the average growth period of the other varieties was 190 days.The difference between the two was quite large,so it was necessary to carry out field management alone.In order to keep the rice painting neat and beautiful,Yucai 3 needs to be pruned every 15 days according to the change of plant height in each period.According to the dynamic tiller change and the result of variety selection,the tiller number ratio of Huangye 3 and Yucai 3 at tillering stop is 5:4.Therefore,the basic seedling number of Huangye 3 and Yucai 3 is 1:1 per hole in order to save the cost.According to the difference of plant height between different planting density and the same planting variety,the Yujing 24 was the main green and the highest rice varities at the viewing period of 1,from June 21 to July 1,when the row distance of plant was 0.18^0.2 m,and the plant height of Yujing 24 was the highest at the viewing period of 1,21 June to 1 July.There was no significant difference between the row distance of the planting plant and the row distance of 0.18×0.3 m.During the viewing period of 2 from July 5 to July 15,there was no significant difference in plant height between the three plants.The spacing between the three plants was 0.18×0.2 m,0.18×0.3m,0.18×0.15m.There was no significant difference in plant height between varieties.During the viewing period of 3 from August 2 to August 12,the height of the plant was the highest when the row distance was 0.18×0.15m,and there was no significant difference between the height of the plant and that of 0.18×0.3m.Based on the analysis results of the above three viewing periods,the best landscape effect can be achieved by using Huangye 3 and Yucai 3 with planting density of 0.3×0.18m on the basis of saving manpower and reducing the difficulty of implementation in the production of paddy field paintings.4、Landscape effect analysis of paddy field painting.Through continuous visual observation and aerial view analysis,it is found that the viewing time of paddy field painting is long from the end of tillering to the maturity of colored rice.The optimal viewing period was 50-56 days after transplantation from the end of tulering to before heading.In this period,it was observed by aerial view that the leaves of rice were brightly colored and highly discemable,and there was no variegation of panicle after heading in the field.The horizontal viewing time is short,and the bird’s eye view viewing method requires the aid of higher terrain or uav.The optimum viewing height of the artificial viewing point was 3.3 times of the height of the rice plant,and the viewing distance was 1.5 times of the horizontal width of the rice paddy field.It is suggested that the viewing position and method of rice field painting landscape should be considered in the design and manufacture of rice field painting.5n Benefit analysis of colored rice produced by paddy field painting.The rice variety with better economic benefits brought by r:ice yield in the paddy field is Huangye 2,and its yield can reach 6.55 t*hm’2.The second was Yucai 1 and Huangye 1 were 6.31 t·hm-2,55.44 t·hm-2,respectively.However,the yield of Huangye 3,Yucai 2,Yucai 3,Yucai 4,Qianziyel,Qianziye 2 and Gaozi varieties was poor,which were 2.42 t·hm-2,3.52 t·hm-2,3.96 t·hm-2,3.89 t·hm-2,2.19 t·hm-2 and 3.50 t·hm-2,respectively.It is suggested that the balance between landscape benefit and economic benefit should be considered in the production of paddy field paintings.6、Optimize a set of rice field painting design and production of the technical process. |
