Effect Of Three Irrigation Methods On Growth And Yield Of Camellia Oleifera

Camellia olifera is one of the world's four woody oil trees,and it's also edible oil tree species native to China,the tree species not only has high economic value,but also plays an important role in biological fireproof,water and soil conservation,and ecological environment improvement.It is one of the important hazard to Camellia olifera planting less rain and heat in summer,in order to improve the water use efficiency and irrigation water method,provide the basis for the summer moisture management of Camellia olifera,make different irrigation treatments,then observation and measurement of related parameters of Camellia olifera,the results showed that:(1)The effects of water content on different water treatments on Camellia olifera leaf had no significant difference,the irrigation treatment oil tea camellia leaves absolute water content was low(57.95%),the drip irrigation treatment oil tea camellia leaves water content was the highest(63.44%),the CK treatment Camellia olifera leaves relatively water content was the highest(93.57%),the flood irrigation treatment Camellia olifera leaves water content was lowest,only 89.15%.(2)Significant effects of different water treatments on leaves physiological indexes.the CK treatment Camellia olifera leaves soluble sugar content was the highest(7.16%),the sprinkler irrigation treatment Camellia olifera leaves soluble sugar content was the lowest(6.31%).The CK treatment Camellia olifera leaves soluble protein content was the highest(3.75%),the sprinkler irrigation treatment Camellia olifera leaves soluble protein content was the lowest,only 3.01%.The CK treatment Camellia olifera leaves conductivity was higher(0.67),the drip irrigation treatment Camellia olifera leaves conductivity was lower(0.47).The drip irrigation treatment Camellia olifera leaves malondialdehyde content was higher(2.65mu-1mol.g Fw),the CK treatment Camellia olifera leaves malondialdehyde content was low.(3)The effect of summer tip growth,summer tip germination rate by different irrigation treatments on Camellia olifera had extremely significant difference,but base diameter size.Summer tip germination rate was highest(77%)by sprinkler irrigation treatment,the CK treatment the summer tip germination rate was the lowest.Summer tip growth length was the longest handle(50.25 cm)by flood irrigation,the CK treatment was the shortest(39.35 cm).The flood irrigation treatmen summer tip was bigger roughness(5.04 mm),the CK was finer(4.71 mm).The drip irrigation treatment the summer tip SPAD value was the highest(60.87),the CK treatment was lower.(4)Different water treatments had significant effect on Camellia olifera autumn shoots growth index.The irrigation treatment autumn shoots germination rate was 33.89%,the CK treatment autumn shoots germination rate was only 9.2%.By drip irrigation Camellia olifera autumn shoots grow faster(16.43 cm),the treatment Camellia olifera autumn shoots grow slowly.The flood treatment,the plant tip was thicker(3.66 mm),the CK treatment autumn tip was finer(3.07 mm).On flood treatment the Camellia olifera leaf SPAD value was lowest(57.63).(5)The results showed that there were significant differences in the yield of Camellia oleifera by different irrigation methods,and the drip irrigation treatment the yield was the highest,reaching 97.07%,and the lowest rate was the CK,which was only about 83.89%.(6)The effect of the yield index by different irrigation on Camellia olifera were not significant difference.The highest yield treatment was the sprinkler irrigation,reached 1447 g,the flood irrigation treatment was lowest(456 g).The sprinkler irrigation treatment Camellia olifera fruit weight was the largest(16.33 g),the flood irrigation treatment were lowest weight.The drip irrigation treatment average seed weight was larger(2.8 g),the CK treatment was smaller.The sprinkler irrigation treatment Camellia olifera seed moisture content was higher(47.75%),the CK treatment seed moisture content was low(42.2%).The sprinkler irrigation treatment the seeds yield efficiency was highest,reaching 50.29%.Every 50 kg Camellia olifera fruit,by sprinkler irrigation treatment the oil production was highest(4.19 kg),by drip irrigation,only get 3.16 kg.(7)The CK treatment Camellia olifera flowering time ahead about 10 days than other treatment,the drip irrigation treatment coated eight days than other Camellia olifera,the CK and drip irrigation treatment blossom early,the drip irrigation treatment flowering time was relatively concentrated,the opening of the flower.Sprinkler irrigation and contrasting flower grows speed is uniform,as time travel,Camellia olifera flowers open,basin irrigation treatment at the end of the flowering late,flowering time,in the middle of december,after flowering rate became faster.
