Greenhouse cultivation of grapes Preliminary Report

Yi (kg) (kg) (kg) (yuan) (yuan) (yuan) (yuan) (yuan), 1988685.5175860.52151154043O1970283l617, shed large 1989761.5236.59982495125020914592831106 average 723.5205.7929.323231395319.51714. 5283.1361.5l exposed 1988690690172566O13O7907201989.906906226582O5O870800 to average 79879819957409083076O 'a _ light performance. It enables the temperature increased from 2.2 to 6.7. C, grape phenology of 17 to 35 days in advance. As long as appropriate measures taken and appropriate varieties, grape plastic greenhouse cultivation, it is possible to improve economic efficiency exponentially. From the two-year test and the actual observation of view, early selection of plastic greenhouse cultivation of large grains to fresh varieties, early maturing varieties in order to be more mature and achieve higher economic efficiency. 2. The test results from two years to see, more serious greenhouse grape fruit drop. Analysis of the reasons: First, light the lack of grape flowering, pollination and fertilization resulted in substantial drop of 1988,1989] ~ years were rainy flowering vine. Second, excessive rise of Branch Flower and fruit drop, shed an average of two years, the amount of 3,000 acres of remaining branches, which in 1989 amounted to more than 3,400 acres of remaining branches. Exposed to an average of 2,400. Third, the studio humidity, high temperature,[link widoczny dla zalogowanych], and partial nitrogen, causing excessive growth shoots and young fruits compete for nutrients. 3. Removing Film premature. Childhood grape ripening fruit enlargement to the requirements of the average temperature of 25 ... 30. C, the test 1981) a 2l a clothing industry in Henan Province Department of Science to improve large grain of table grape Kyoho the Fruit Experimental Institute of Horticulture, Henan Province, Zhengzhou City Academy of Agricultural Committee of Large Kyoho table grape because of its large fruit grain appearance beautiful and loved by consumers, with high economic value. But the Department of grape prone to falling Kyoho fruit drop, fruit was not high, if not properly managed, then the edge of Ear sparse, affecting the yield and commercial value. Flower and fruit drop occur in order to find effective control methods, from the boron spray, spray ethephon,[link widoczny dla zalogowanych], pinch ear tip carried out some tests and so on. First, the test material and methods' �� test varieties as 5 years old Jufeng, spacing of 1 �� 2 m, single Li Jia planting, tree vigor is weak. 'Test is: a randomized block design with three replications,[link widoczny dla zalogowanych], each plot is 11, set 4 treatments, determined by the Fruit bagging treatment: 1. Heavy Topping: 1 results remain above the leaf inflorescence branches Topping, Topping normal vegetative shoots; 2. Topping the results of the normal branch, and 0.3% of coral sand spray ', 3. Spraying ethephon 15ppm ~. 14. Control, normal topping. 'Treatment-resistant of all in the May 11, for the Kyoho flowering. Yu Zhao-Nian Ji Lu Yanzhou Xiang Zhai Peng Zhen Guo Xiuzhen sector II test results and analysis of treatment, to June 1 survey results,[link widoczny dla zalogowanych], the highest rate of fruit is for 2, the control fruit was 123.4% followed by treatment l, 104.9% for the control, fruit is the lowest rate for 3, 90.6% of the control. . In addition, we made a pinch on the ear of grape garden tip of the Fruit Experimental <see attached) within a week in the flowering stage. It can be seen from the Schedule, pinch ear tip can significantly improve the Department of grape fruit Kyoho rate, more importantly, can improve the tightness of the ear, so that the ear is more beautiful and increase its commercial value. Can be seen from the Schedule, the black Olympus - too high in fruit body Jufeng, so the effect of sharp pinch as huge spike unlucky. III Summary - / 1. For weaker grape tree vigor in the first flowering of boron and heavy topping spray can improve fruit set, respectively 23.4% and 4.9%. Ethephon sprayed on the weak tree, due to inhibition of Schedule Kyoho Grapevine Series by beating the tip of the Fruit of h'J �� depression: pinch point refers to the flower spike inflorescence axis length before removing 1 / 3 of a V2. In the middle of removing film in May, when the swelling is the color of the greenhouse grape, and in May the average temperature is 19.4-19.9 in mid-air. C, can not meet the fruit matures, the needs of the role of color, but reduced fruit set percentage, 9.5% lower. 2. Pinch ear tip can significantly improve the Department of grape fruit Kyoho rate, an average of 81.8% of pinch point on the ear was better than the black Kyoho Olin, and can increase the tightness of the ear, so that the ear is more beautiful and improve the value of the goods, so Kyoho spike tip pinch Department of grapes to improve fruit set is a simple and effective measures. To. Thus, mature slowly, coloring poor. Appropriate time to expose shelf stable at ambient temperature should be 25. C later. 91, No. 4 one. :
