The invention relates to a method for getting rid of seasonal dormancy of fruit trees. The processing method for getting rid of the seasonal dormancy of the fruit trees includes the steps: (1) collecting fruit tree branches which are with full flower buds and in a dormancy period when chilling requirements satisfy one third, and carrying out water planting with GA4 solution; (2) putting the fruit tree branches through the water planting into an illuminating incubator and carrying out statistic on a germination rate of the fruit tree branches ten days later to confirm the dormancy state of the fruit tree branches. Compared with a current common dormancy breaking agent of lime nitrogen, the GA4 is small in toxicity, preparation of the solution of the GA4 and spraying the solution of the GA4 are simpler and easier than smearing of the lime nitrogen, and the dormancy breaking effect of the GA4 to the flower buds the fruit trees is better than that of the lime nitrogen. The GA4 is utilized to carry out the dormancy breaking processing on the fruit trees, so that the method for getting rid of the seasonal dormancy of the fruit trees has a good theory base and a good market prospect.

The invention discloses a method for regulating and controlling a flowering phase of peach cut-flowers and guaranteeing the flowering quality. The method for regulating and controlling the flowering phase of peach cut-flowers and guaranteeing the flowering quality disclosed by the invention comprises the following steps: determining a pickup date of the peach cut-flowers according to the selected optimal ornamental date, performing low-temperature treatment according to the chilling requirement after the peach cut-flowers are picked up at the pickup date, obtaining peach cut-flowers in natural dormancy, performing flower forcing treatment, and obtaining the peach cut-flowers in the optimal ornamental period. According to the method disclosed by the invention, the flowering phase on the specified date can be regulated and controlled by combining environmental control according to different chilling requirements of different peach cut-flower qualities, for example, early-maturing varieties are guided to bloom on Christmas Day, New Year's Day and Spring Festival, and late varieties are guided to be in full bloom on May Day even can bloom on each needed festival. The method has significance in promoting development of sightseeing agriculture and Peach Flower Festival and realizing greater social benefits, landscape benefits and economic benefits.

The invention discloses a chilling-free cultivating method of peaches in a greenhouse. Through a series of chilling-free cultivating technological means including the step of promoting flower buds to fully differentiate in advance, the step of spraying nutritional agents, shielding light and closing a plastic shed so as to make leaves fall, the step of spraying dormancy-breaking chemicals, controlling the temperature and promoting flowering, the step of spraying fruit-setting and branch-promoting agents to prevent secondary dormancy, the step of reasonably regulating and controlling the temperature and humidity, the step of manually compensating for light and the step of applying carbon dioxide fertilizer, the mature period of peaches in the greenhouse is greatly brought forward. The method has the advantages of being wide in suitable variety range, high in operability, accurate in regulation and control, high in increased benefit and the like, is suitable for being applied to greenhouse precocity promoting cultivation of most of middle-early ripen peaches with a chilling requirement of 700 hours or fewer in present production, also has quite high guidance significance in regulating the mature period of other northern fruit trees, and makes peaches in the greenhouse ripen as early as possible and appear on the market before the spring festival, the peaches can meet the requirements for the spring festival consumer market and sightseeing and picking, the sale price is several times to ten times or more the price of peaches appearing on the market in April and May, and the benefit increase is quite remarkable.

The invention provides a method for measuring the chilling requirement of cherries through semi-vivo culture. The method comprises cherry branches are collected; the cherry branches are culture at low temperature; the cherry braches are culture at room temperature, the flower bud germination rate and the leaf bud germination rate are counted, and the chilling requirement of the cherries is measured; according to the method for collecting the cherry branches, the base portions of the branches are pruned flat, the length of the branches are controlled to be 30-50 cm, and at least five flower buds are reserved in each branch. The low-temperature culture and the room-temperature culture are used alternately, so that external conditions are simulated as far as possible, the temperature is effectively controlled, the branches are avoided from being affected by the uncontrollable factor, namely external temperature, or the external temperature is recorded by means of other devices, and convenience is brought to the calculation of the chilling requirement.
