Study In Key Cultivation Techniques Of 'Yulu' Flat Peach Shanghai

In this experiment, on the 6 year-old'KaiXin'shaped'Yulu'flat was which were cultivated in greenhouse, we observed the phenology and do some research on early spring freeze injury, artificial pollination, trimming test, Fertilization and others related, and we compared the phenology and fruit quality of'Yulu'flat peach which was cultivated in greenhouse to the one in open field.The results showed that: the main phenology of'Yulu'peach in greenhouse than the one in open field advanced about 15 days, flowering from March 20 advanced to the March 5; mature from the end of July early August advanced to around July 20. When temperature below 0℃we shoud carry out irrigation or smoke in the canopy, because of being vulnerable to frost damage in early spring,and flower pollination was need, and a pencil eraser head pollination rate than non-pollinated fruit set more than 400% increase. Due to high relative humidity tent being difficult to spread pollen, pollination can be carried out from the early flowering stage.'Yulu'flat peach fruit-quantity is related different trim levels, and cutting lighter fruit set not higher, moderate pruning role in improving fruit set rate. Temperature on damage to young fruit than flower for flat peach cultured in greenhouse, can result in fruit drop; the greenhouse temperature should be controlled below 25℃in the period of flowering and young fruit. Application of fruit expansion fertilizer to improve the quality of'Yulu'flat peach was significant role, but fertilizer will not be obvious to a certain extent. Fruit maturity of peach in greenhouse was less susceptible to external environmental factors, and product yield and quality was more stable than the open field cultivation.
