【Abstract】 The experiment researches and demonstrates application of the 7-years "Hongdeng" sweet cherry in Fumin village of Qingxi country in Hanyuan county of Sichuan province, from aspects of species and mixing ratio of basic fertilizer, mixing ratio and species of additional fertilizer, promoting blossom by growth regulator and pruning pattern, regulating fruit-setting rate of flower and fruit by growth regulator, fruit quality, mature stage of fruit, artificial pollination experiment, pest and disease pollution-free control, economic benefit and so on, and creatively proposes the integrated technology for safety, good quality and high yield of sweet cherry. The research results are as follows:1. Effect of formulated fertilization of circular furrows cave storing fertilizer and waterplus plastic film mulching(1) 3.75 Kg of dried chicken manure,1.5 Kg of superphosphate and 1 Kg of urea used as basic fertilizer were applied to plants of the 7-years tree by circular furrows cave storing fertilizer and water plus plastic film mulching; thereby, the embryonic stage was 2-5 days earlier than that of the contrast, the full-bloom stage was 3-6 days earlier than that of the contrast; irrigation times per mu could be reduced by 1-3; 4125 Kg of water can be saved, which was up to 51%; fertilizer cost per mu could be reduced by 60 yuan,23.1% of fertilizer could be saved, opening rate of fruit was less than 5%.(2) 3.75 Kg of dried chicken manure,1.5 Kg of superphosphate and 1 Kg of urea used as basic fertilizer were applied to plants by circular furrows cave storing fertilizer and water plus plastic film mulching; the best effect of after fertilizer was to apply 1.5 Kg of high-nitrogen composite fertilizer to budding fertile plant and high-potassium composite fertilizer to fertile plant in fruit swelling period, the average inflorescence fruit-setting rate was up to 71.6%, the average weight of single fruit was up to 11.5 Kg, TSS was up to 17.9%; the worst effect was to apply 0.5 Kg of urea to budding fertile plant and 1 Kg of Yangkang biological fertilizer to the fertile plant in fruit swelling period, average inflorescence fruit-setting rate was 20.9% higher than that of applying 1.5 Kg of high-nitrogen composite fertilizer to budding fertile plant and 1.25 Kg of high-potassium composite fertilizer to the fertile plant in fruit swelling period, the average weight of single fruit was 2.9 Kg higher, TSS was 1.5 percentages higher, and difference between organic acid and Vc was unremarkable.2. Influence of growth regulator on fruit-setting rate and fruit quality(1) Fruit-setting rate of sweet cherry was affected greatly by being processed with different growth regulators. All results of spraying growth regulator in initial bloom stage were higher than the contrast remarkably, in which fruit-setting rates of sweet cherries sprayed with 30 mg/L GA3,20 mg/L 6-BA and 10 mg/L PCPA were remarkably higher than that of other processing,28.1% higher than natural fruit-setting rate, and 24.8%, 18.4% and 24.2% higher than that of the sweet cherry sprayed with PBO, respectively; fruit-setting rates of sweet cherry sprayed with 20 mg/L GA3,20 mg/L 6-BA and 30 mg/L PCPA, and sweet cherry sprayed with 30 mg/L GA3,10 mg/L 6-BA and 30 mg/L PCPA were remarkably higher than that of other processing, but the difference was unremarkable; fruit-setting rates of sweet cherry sprayed with 20 mg/L GA3,20 mg/L 6-BA and 30 mg/L PCPA, and that sprayed with 30 mg/L GA3,10 mg/L 6-BA and 30 mg/L PCPA were 24.3% and 21.7% higher than the natural fruit-setting rate, respectively. It illustrates that 20-30 mg/L gibberellin and 10-20 mg/L 6-BA can improve the fruit-setting rate remarkably. Effect of 250-fold PBO is the best, which is 8.2% higher than the natural fruit-setting rate.(2) Application of GA3 in blooming stage of sweet cherry could remarkably improve fruit quality and increase weight of single fruit, and relatively concentrate collection periods. In comparison with the contrast, spraying 10 mg/L GA3 at the 10th and the 20th day after blossom can increase weight of single fruit by 0.80 g, increase soluble solid by 2.13%, increase sugar content by 1.01 g/100 g, decrease acid content by 0.114 g/100 g. Mature stage of the contrast lasted for about 13 days; mature stage after GA3 processing lasted for about 6 days. The mature stage was concentrated within 54-57 days after blossom. About 80% of fruits matured within 2-3 days intensively; and the collection period was within 3-4 days.3.Blossom bud forming rate of 40-50cm fresh treetop was up to 47.8% after being continuously sprayed with 15% PP333 of 500 mg/L twice at late May and early June and top removal, so formation of blossom bud was promoted effectively. 4.1t primarily finds that Chinese cherry—Hanyuan white cherry can be used as excellent pollinated variety of’Hongdeng’. Effect of the white cherry is better than result of pollination among different species of sweet cherry. This finding can solve the problem that pollination pollen is insufficient because the pollination tree is insufficient in sweet cherry production. Thereby breeding germ plasm resource of sweet cherry is enriched, which is theoretically and practically important to and theoretically valuable to direct sweet cherry production and new species breeding. Chinese cherry—Hanyuan white cherry is remarkably different from other pollinated varieties, the inflorescence fruit-setting rate thereof is more than 70%, blossom fruit-setting rate is more than 40%; the second is Juhong sweet cherry, inflorescence fruit-setting rate of which is more than 60%; the worst is Hongyan sweet cherry, inflorescence fruit-setting rate of which is 17.1%.5.In the aspect of pest and disease pollution-free control, physical control and biological control were combined. Any artificially synthesized pesticide was not sprayed to sweet cherry in fruit growing period. Tested by food quality supervision, inspection and testing centre of Chinese ministry of agriculture, the product quality accorded with NY 5112-2005 pollution-free food standard.6.Application demonstration of integrated technology for safety, good quality and high yield of sweet cherry.(1) A standard integrated technology for safety, good quality and high yield of sweet cherry was performed, therefore embryonic stage was 3-4 days earlier than that of the contrast, full-blossom stage was 3-5 days earlier, the mature stage was 3-4 days earlier; the average inflorescence fruit-setting rate was up to 69.1-72.3%, which was 18.7% higher than that of the contrast; the average yield per plant was 53.6% higher than that of the contrast, the weight of single fruit was 19.1% higher than that of the contrast, the TSS was 17.8% higher than that of the contrast, the organic acid content was slightly lower than that of the contrast, difference between the Vc content and that of the contrast was unremarkable. The average economic benefit per mu could be increased by 16600 yuan. It fully illustrates that the integrated technology for safety, good quality and high yield of sweet cherry plays a huge role in promoting the development of local agricultural economy and income increase of peasant. (2) In 2009, achievements of the integrated technology for safety, good quality and high yield of sweet cherry were appraised by experts of Sichuan province. It is believed that the technology is of strong pertinence, scientific experiment design, reasonable technology roadmap, accurate data and credible research result, and is theoretically and practically important to sweet cherry production in high-altitude arid, semi-arid ecological region in western mountains of Sichuan province. Meanwhile, scientific and technological achievements thereof were registered.更多还原
