中文摘要	【目的】探究不同杏李品种在干旱区的生长动态,为丰产优质栽培提供理论依据。【方法】在不同生育期、天气和土壤水分条件下定期测定不同杏李品种新梢、叶片、茎干的生长变化,分析及其变化规律和相互关系。【结果】风味皇后’味帝’味王’和味厚’的新梢生长旺盛期为4月14日至5月10日;叶片生长旺盛期均为4月14日至5月8日;茎干生长旺盛期为5月15日至6月16日。茎干粗度日变化呈明显的昼夜规律,表现为8:00左右达到一天中茎干粗度最大值(MXSD),16:00左右达到一天中茎干粗度最小值(MNSD)。48月,味厚’的茎干粗度呈上升-下降-上升-下降的趋势,5月份茎干粗度生长量达到最大,4月份出现最小值。58月,杏李在晴天的茎干粗度日收缩量(MDS)与日增长量(DI)都明显大于阴天。味厚’茎干粗度灌溉后MDS小于灌溉前,但灌溉后DI明显大于灌溉前。【结论】杏李在阿克苏地区的新梢、叶片和茎干生长存在明显交替现象,茎干与新梢和叶片的生长旺盛期相互错开。味厚’茎干粗度日变化表现出明显的昼夜规律,大致可分为3个阶段:收缩阶段、复原阶段和生长阶段。5月份茎干粗度生长量在全生育期内达到最大。不同生育期、天气、土壤水分条件对杏李茎干粗度的变化存在显著影响。
英文摘要	【Objective】Continuous observation of the growth of branches and leaves of Prunus salicinaarmeniaca in an arid areas, in order to understand the growth and development of the tree. The dynamic micro change of the trunk diameter was an important index to study the water and growth status of plants. The micro variation of the trunk diameter and its response to environmental factors were discussed, which provided a scientific basis for the micro changes of the stem diameter to guide precision irrigation. The study aimed to investigation the growth dynamic of new shoots, leaves, and trunks in arid areas, so that we can effectively guide the production of fruit trees. Utilizing local take corresponding cultivation and management measures, scientific fertilizer and water management, allows us to do a good job in the management of the orchard, and thereby providing some theoretical basis for high-quality cultivation of Prunus salicinaarmeniaca.【Methods】When the new shoots and leaves grew, they were measured and recorded every 5 days. The leaf area was measured by theYaxin-1241 leaf area meter,and the leaf weight was determined using a portable electronic balance. Continuous automatic monitoring of the plant stem diameter growth by using a plant growth measuring instrument, and two growth measurement instruments DD1, DD2, DD3, DD4 were installed in the ground more than 100 cm from the North-South trunk, utilizing the tin foil protective treatment. The selection was about 5 cm in the middle of the test tree canopy. Before the installation, we used a blunt knife to scrap the trunk skin, to ensure that the instrument frame was solid and that the probe and the main contact were good. The probe was wrapped in foil, to prevent the direct effects of wind, temperature and rainfall on the probe. The measuring probe was fixed on the side near the base position monitoring. Regularly checking was done to ensure whether the instrument was loose, and we also performed timely calibrations. Our test selection consisted of 3 experimental trees, with each tree being set up with 1 sensor. The automatic data acquisition system was set every 5 min for automatic measurement of the diameter of the data. Under different growth stages, weather and water conditions, the growth of the new shoots, leaves and stems of the different varieties of Prunus salicina * armeniaca were regularly measured, and their changing rules and the relationship between them were analyzed. We also did an analysis of their variation law and mutual relationship.【Results】The average annual growth rate of the new shoot lengths for Prunus salicinaarmeniacaFengweihuanghou’,Prunus salicinaarmeniacaWeidi’, Prunus salicina* armeniacaWeiwang’and Prunus salicinaarmeniacaWeihou’were 7.28, 8.84, 7.92, 6.38 cm, respectively. The average values of the new shoot growths were 3.18, 4.08, 3.92 and 3.57 mm, respectively. The average annual growth rates of the individual leaves were 7.28, 7.86, 6 and 6.26 cm, respectively. The average growth rates of the single leaf widths were 3.02, 3.62, 2.54 and 3.34 cm, respectively. The annual growth periods of a single leaf were 28, 36, 35 and 26 d, respectively. When the leaves were stable, the average leaf areas of the individual leaves were 18, 25.1, 12.3 and 13.5 cm~2, respectively. The mean leaf weights of a single leaf were 2.57, 3.35, 4, 2.85 g, respectively. The new shoots slow growth period for Prunus salicina armeniacaFengweihuanghou’, Prunus salicina * armeniacaWeidi’, Prunus salicina * armeniacaWeiwang’and Prunus salicina*armeniacaWeihou’were between April 10 th to April 16th, and mid May to early June. The stem exuberant period was between May 10 th and April 14 th; the trunk diameter of the slow growth period appeared in early April to mid May, and late June to late August. The stem exuberant period was between mid May to mid June. The daily change of the trunk diameter showed a clear day and night regularity.
