Increase the rate of apricot fruit of several technical measures


Quantity and quality. Therefore, to mitigate or eliminate the negative factors above problems is to get the key to high yield and quality apricot. 1 selected cultivars, configuration management units to determine pollination tree varieties, is to increase fruit set, access to an important basis for high yield. Under construction around the park be sure to select the appropriate local growth, high value goods varieties, field introduction, is not clear in the results of the growth and adaptability to promote the former must not blind. Conditional, can be planted a small trial, the results obtained after the line to be expanded. According to the trial. Varieties cultivated in the current production has Longwangmao, rush, excellent one, Kitayama large flat, white flat and so on. Results sets can be all over the local natural and climatic characteristics of flexible options. Construction should also pay attention to Taiwan and pollination tree species group configuration. Ensure proper pollination. 2 regulation of delayed flowering. Avoid the use of low-temperature hazard Fushao delayed flowering 21 to improve the quality of flower buds. Second, the formation of flower buds can be made Fushao open late from 5 to 6 days. When the shoots grow to 30cm above. Cut 1 / s trigger the second shoot, shoot bud differentiation in the second one when a small amount of fertilizer applied. To a certain extent, can be taken to improve the quality of the winter bud re-cut, a large number of training methods topping summer fruit Fushao technology, so that delay flowering to avoid frost. 22 Jing delayed flowering spout drugs. It was reported last autumn in late September early October ~ spraying 50 �� 10 ~ ~ 1ooxi0 gibberellin may defer leaves of 14 - 20 days, so the body has accumulated more nutrients in the village. Full flower bud development, and delayed flowering 8 ~ l0 days. Early spring,[link widoczny dla zalogowanych], the buds swelling on the spraying 500 �� 10 ~ ~ 1000 �� 10 GA or 500 �� i0 a ~ 2000 �� l desert 'green fresh hormone (MH) may be delayed flowering 4 to 6 days. 2.3 water antifreeze,[link widoczny dla zalogowanych], white-trunk. Irrigation can not only reduce the surface radiation, and to supplement the water trees to increase air humidity, dew point temperature increased. Reduce the degree of cold cellar, but can also delay flowering 3 to 4 days. Coated with the lime trees in early spring, either killing, but also play a frost to save results. 24 fume frost. Fumigation method is a traditional method of orchard frost. Fume addition can release some energy, improve orchard temperatures, but also because the formation of carbon dioxide and water vapor} smoke prevented the sinking and the flow of the air war. Received :1998 -08-03, 36 -, f so that the temperature Buzhi Yu Guang down to the critical damage caused by Qu Zhai degrees. 2.5 Protection of flower bud and young fruit Pharmacy spraying foliage of Jing and Bo fat sodium humidifier can help prevent a strong wind and low temperature charge and the young fruit of apricot damage. 1:60 Jing concentration of protection is appropriate. Too dilute poor results. The role of a cut too thick. Also note that can not be applied in full bloom, so as not to affect pollination. Fang Feng Xing for the insect 3 apricot flowers, stupid bee pollination and insects can help to improve fertilization, candied fruit after pollination, the opportunity to spend fast construction speed up the orange tube growth. Wang Wen to shorten the time to be pregnant to reduce the possibility of suffering harm. Because of low resistance Osmia Zhai, visiting construction degree fast, chou pink ability. Therefore,[link widoczny dla zalogowanych], the best stocking Osmia apricot. To improve the rate of 4 artificial pollination fruit to make up for deficiencies of poor natural pollination, can be granted artificial orange, point granted, or possession of spray pollen nutrition nutritional formula plus 10g per 5kg ball pollen, borax, ISg urea, 150g sugar, a little detergent artificial pollination should be carried out in the flowering stage. Yao flowering by short, should prepare in advance for 5 flowering spray, spray Ju, choke fertilizer in the spring drought,[link widoczny dla zalogowanych], flowering windy areas,[link widoczny dla zalogowanych], Yao Zhu head for dry flowers of pollination, fertilization. After spraying a small increase in the humidity and pollen opportunities to engage with the stigma created pollination, fertilization conditions for rapid construction of pollen germination. In addition, spray before flowering and full flowering of a 0.2% 0.1% �� sand or 02% urea could improve fruit set and yield. If Mount Tai robbery of spray 0.5% 0.3% 0.3% urea, or potassium dihydrogen monument acid supplements can reduce fruit drop. Strengthen the Ba 6-management, combined margin of fertility control to enhance water management in the worm, they enjoy a reasonable cut, regulating the growth of vegetative growth and reproductive relations, can effectively improve the quality and the drum volume of flower buds, flowers abortive alkali than step down. Pest control can delay the time deciduous trees to increase nutrient shed tired, and enhance tree vigor, fruit set percentage of increase is also actively promote the oak with a stick. Of Jane: Zhang Zhongliang. Male. Fung was born in March 1958. Education City, Western Province, who Steep Forest and graduated control of economic forest. Shaanxi Provincial Academy of Forestry engineer now. Participate in the anti-Jealous Linlei Weibei made spicy lamb stick Wong wide research, Ministry of Forestry Science and Technology Progress in 1997 possession of three cows Qiang afternoon. has in hi class academic journals, published in the journal border the stove economic aspects of forest research paper competition 28.
