The invention discloses an efficient and sustainable production method for a greenhouse and fruit tree potting media. The method includes the following steps that fruit tree varieties with low chilling requirements are selected in the mid-to-end of March, and greenhouse preliminary seedlings are cultivated outside the greenhouse in a matrix cultivation mode; vegetable production through conventional facilities is carried out inside the greenhouse from the mid of April to the mid of October; in the mid of October, the preliminary seedlings cultivated outside the greenhouse are transferred into the greenhouse for cultivation until the mid of April of the next year; after fruits are picked, the preliminary seedlings are moved out of the greenhouse for conventional management. According to the innovated planting mode, the method that vegetable production through the conventional facilities is adopted in spring and fruit tree production through the facilities is adopted in winter, so facility soil can be cultivated and leave unused alternately, the utilization maximization of the facilities is achieved, economic benefits are achieved, and sustainable development of facility soil ecology is achieved.

The invention discloses a method for promoting none-flowering-phase kiwi fruits to flower under the in vitro condition. The method comprises the steps that certain chilling requirements are accumulated for in vitro twigs, an appropriate external environmental condition is given, the twigs are made to grow and develop in an established mode, and the purpose of generating flower buds and flowering ahead of time is achieved. Compared with the prior art, the method has the advantages that the none-flowering-phase kiwi fruits can obtain the flower buds, and the germplasm innovation for kiwi fruit haploid (double haploid) can be conducted multiple times in one year; the application scope is wide, the method can be popularized to other woody fruit trees, and original experimental materials are provided for the germplasm innovation based on the haploid (double haploid) technology.

This invention is a new and distinct sweet cherry tree denominated ‘IFG Cher-four’. The new sweet cherry tree is characterized by producing medium size blushed fruits having flat-round shape. Fruits ripen early, about Apr. 26, 2014 in Delano Calif. The ‘IFG Cher-four’ has medium firm, medium acid fruit with a good cherry flavor. Fruits are tolerant of rain induced cracking. The sweet cherry tree has a medium low chilling requirement, about 300 to 400 chill hours.

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.
