Introduction Of New Chinese Cherry Varieties And Study On Their Rain-shelter Cultivation Techniques

Taizhou is Zhejiang’s Chinese Cherry producing area, the area accounted for almost half of Zhejiang, due to higher economic benefit, development of cherry boom in recent years repeatedly, some cities and counties to develop as a key area of cherry, relatively fast development. But at present, there are still some problems existing in Chinese cherry production, varieties of a single, small fruit, poor appearance quality; cultivation techniques of low degree of standardization; fruit cracking, bird appears in process of cultivation, commodity value is not fully embodied, difficult to adapt to the fierce market competition, thus limiting the development in the area of high quality Chinese cherry. In this paper, through the introduction of large type Chinese cherry varieties, regional culture, the effective way to improve the quality of the cherry, cherry producer improve quality, and provide a theoretical basis. At the same time, also help to expand the production scale to promote quality cherry in Jiangnan area, the rich fruit market supply and to meet the needs of consumers.The results of this study show that:1) the black pearl, Bataan early red, Zhu Hong the three varieties of fruit weight is more than3G, the soluble solids content is above15.3%, the comprehensive characters of outstanding performance.2) in Cherry flowering, fruit core hardening stage, color stage spraying, spraying amino acid was1200times the best effect, increase the fruit setting rate is14.2%, single fruit weight increased by22.6%, increase the soluble solids content of1.9%.3) by spraying6g/L calcium chloride+1000times after spraying boron amino acid potassium calcium, film mulching, film mulching and rain and erection after spraying, to open the control, treated by spraying1times1000amino acid boron potassium chloride and6g/L calcification calcium and erecting shelter facilities and film mulching best, average fruit cracking rate reduced25.7%.4) cover film shelter facilities to cherry blossom time for good, high quality fruit rate77.9%, decreased the rate of55.8%, but also to reduce bird damage.5) in Taizhou area in spring, the grafting in mid February,-3month is appropriate, in mid February, cut grafting method was highest, up to82.8%.6) through a number of experiments, a set of Chinese Cherry rain shelter cultivation techniques of high quality and efficiency rules.7) the photosynthetic characteristics of Chinese Cherry, the illumination intensity decreased by28.0%to33.1%, light saturation pointbs and light compensation points of chinese cherry is reduce,Light use efficiency is no significant differences,Or there were very significant reduced for transpiration rate, Water use efficiency is significantly improve.
