Keywords: Pistaciachine ~ sBunge; Phonology; Growthprinciple good grape to explore the effect of delayed planting the annual supply of fresh grapes means Pingdu City, Shandong Province in 1998 fruit station delays cultivation of grapes,[link widoczny dla zalogowanych], that is before the frost, the grapes planted on the field simple protection, to delay harvest. The results showed that: (1) improve grape quality. Normal grape harvest, soluble solids content is generally about 18%, while the delay of the grapes are cultivated in more than 20%,[link widoczny dla zalogowanych], and the golden fruit,[link widoczny dla zalogowanych], bright hi ��. (2) is conducive to the accumulation of nutrients back to Luk. Delayed planting can avoid frost damage grape leaves, extending its growth time, for the mature branches will help return nutrients, flower bud and the security barrier winter tree. There are two specific ways: (1) plastic tarpaulin to avoid frost protection film. Coverage before the first use of stone grapes Gracilaria frame (or concrete pillars) as pillars above the grape leaves l0 ~ 15era at the top, about 4cm long bamboo pole fixed as beams, top of the formation of grape solid frame structure,[link widoczny dla zalogowanych], covered by plastic and then tarpaulin membrane, surrounded by ropes taut, preventing large wind Shao. After days and nights without removing film coverage, before and after the harvest until the end of snow, covering the period of water 2 - 3 times to keep the ground moist. (2) plastic shed security. 3 to 4 lines for every grape is a structure, using both sides of the column's top fixed-line to make a bamboo arch, arch height from the top of grape leaves 20 ~ 30cm, will join a solid bamboo arch, and then covered Wu Dimo . Gaiyan while surrounded by thin, the whole garden shed into a piece. Council opened the four-day film, ventilation and cooling, put it back the same place at night with strict preservation of earth pressure, bearing in mind the water moisture. Either way, both in the frost before the 1 ~ 2d be covered and protected. About protection of 25d. To the snow around the end of the appropriate. Abstract (on fruit) 1999. (2)
