In this paper, apricot, grape, peach as test materials, key research facilities apricot, grape, peach photosynthetic characteristics, the characteristics of flower and fruit development, natural sleep characteristics, summed up the development of its supporting technical regulations. The main results are as follows: 1. Different species of photosynthetic curve basically the same trend. Different inter-varieties the light saturation point and the compensation point inconsistent. In plastic shed should pay attention to the kinds of high light saturation point of the site shed light intensity, and varieties of low saturation point in the weak light shed on both sides and the rear. In greenhouse cultivation to take various measures to increase the light in the greenhouse, in order to improve the photosynthetic rate of the fruit trees. In protected cultivation, light and of CO 2 concentration is the main limiting factor of photosynthesis shed light difficult to adjust and improve the CO 2 concentration easier, and can make up light weakened due to the decreased photosynthetic ability. Facilities peach leaf net photosynthetic rate was a bimodal diurnal variation curve, the net photosynthetic rate reaches its maximum around 10:00 am, 14:00 pm peak times, 11:00 to 12:00 net photosynthetic rate decreased. 2 different species, varieties chilling requirement of a significant difference, as early maturing varieties, 620 to 940c.u peach flower buds, buds 500 to 910c.u; apricot flower buds, buds were 790 to 920c.u , 790 to 910c.u; chilling requirement of the grape is generally 1010 to 1840c.u; The same species, varieties need cold significant difference between years, indicating a genetic characteristics chilling requirement of deciduous fruit trees, and its expression is regulated by environmental factors. The same species of flower and leaf buds chilling requirement is inconsistent, the underlying trend is higher than the leaf buds flower bud chilling requirement. The relationship between the chilling requirement of fruit development period of the different varieties of the same species without necessarily inherent law. Spraying 6-BA the GA 3 delayed leaf senescence, the leaves fall off naturally compared with the control was delayed for 6 to 9 days; spraying 6-BA although deciduous night, but under greenhouse conditions bud early, high germination rate, estimate the statistics chilling requirement of relatively low; GA 3 in delaying the natural shedding of leaves, buds need cold amount significantly increased; ABA accelerate the aging and shedding of leaves, the leaves naturally fall off compared to control in advance of 4 to 7 days, no significant effect on the buds need cold amount. 4. Facilities apricot powder germination rate significantly lower than the open apricot pollen to maintain a high level of activity and germination rate within 18 hours of post-harvest, after germination rate decreased and apricot powder at room temperature for a very short time.
