Second, cause 1. Growing seasons in recent years, production practices surveys, the incidence of tomato empty fruit influenced by the cultivation season,<a href="http://www.toryburchsoutlets.com" target="_blank" class="postlink">tory burch outlet</a>, the same crop varieties in the winter and early spring greenhouse crop planting hole when the tomato fruit was significantly increased, whereas autumn and winter and late spring crop stubble cultivation Space Stream If low incidence. 2. When stimulated by hormones pollination in greenhouse tomato in winter and early spring, Flower and fruit drop occur in order to prevent hypothermia to improve the rate of tomato fruit, in the flowering plant growth is usually 2,4-D or tomato dip flowers spiritual treatment. After flowering, pollination and fertilization is not dipped in the hormone stimulation, the ovary enlargement, accelerated fruit development, maturity early. If the dip is too high hormone levels take treatment or repeated dip flowers, easy to form a hollow fruit. 3. Formed due to bad weather in the flowering of tomato fruit set, if the event of continued rainy weather, snow, light enough to reduce photosynthetic products, fruit internal nutrient supply, resulting in skin growth and Zhang Xiaodan, Xiangfan City in Hubei Province Bureau of Agriculture, 44lO2l Zhang Xiaodan and pulp growth is not coordination, easy to form a hollow fruit. Tomato seedling crop of winter and the first one or two flowering inflorescence, the weather changing, light of varying duration, in case Lianyin long, low light intensity, light and temperature conditions inside the greenhouse is poor, easy to form a hollow fruit . Then the same ear in the late flowering of the fruit, the empty high incidence of fruit. 4. Improper management practices and improper management of tomato induced an important factor in empty fruit occurred. At temperatures above 35 �� and the duration is longer, poor pollination and fertilization, fruit development in the pulp tissue cells and accelerated seed maturation and fruit growth rate of lack of coordination, the formation of empty fruit. Amount of water and fertilizer after fruit set amount of irregularity, or late in the growth and results of peak fertility and inadequate nutrition, lack of nutrients causes the formation of empty fruit. Third, the preventive measures 1. Select suitable varieties are not under the Greenhouse Crops and time to market, usually a large selection of late-maturing varieties of fruit, a large number of fruit varieties more than cardiac, fruit within the next is greater, such as hair powder 802, good powder 15, 17 , the complex 9 and so on. 2. Proper use of plant hormones on flowering tomato plants to the proper use of growth hormone, with 10 ~ 2om ~ / kg of 2,4-D applied in the stalk at the liquid, or 25 ~ 40mg/kg spirit of tomato dip flowers, or spraying concentration of 15 ~ 2Om ~ / kg of PCPA, every 2 days to process 1. Generally dip at 11 am before the end of the flower. In the summer hot season,<a href="http://www.uggssonline.com" target="_blank" class="postlink">uggs online</a>, the use of hormone dipped roses, spraying should be a corresponding reduction in the concentration, the general use of 10 ~ 15mg/kg appropriate. 3. Strengthening water and fertilizer management to achieve the tomato plant 20o2 / 7 Li with nitrogen, phosphorus, potassium,<a href="http://www.ralphlauren-outlet.net" target="_blank" class="postlink">ralph lauren outlet</a>, and strive to results on growth and root and shoot than coordination and avoid over-lush growth of foliage, so plant growth and reproductive growth of the nutritional balance of water supply, according to the different growth stages and soil moisture and watering intervals to determine the number of days taken to Ditch irrigation methods, the coexistence of fruit per ear swelling peak, with water dressing. If the phenomenon of premature aging plants, the use of potassium dihydrogen phosphate 0.3% ear fruit enlargement in section 2 when spraying, spraying every 6 to 7 days 1, 2 or 3 times even spray. 4 to improve the regulation of light and temperature conditions in winter light, temperature is an important development to ensure good conditions for fruit in the management measures in a timely manner according to the weather changes Uncovery straws, sunny day after sunrise, as long as the temperature does not drop curtain exposed to in a timely manner Peel off the straws, increasing illumination time, the continuous snow weather, to promptly remove snow from roof surfaces,<a href="http://www.uggsnederlande.com" target="_blank" class="postlink">uggs nederland</a>, for scattering light, early evening sunset cover curtains, warming heat. General requirements to maintain the temperature inside the greenhouse in the daytime temperature 20 ~ 27 ��, the night temperatures of 8 ~ 14 ~ C, 8 �� to avoid the continued low Pu. Case of rain and snow weather continued cloudy during the day to ensure the room temperature of not less than 18 ~ C, minimum temperature of 8 �� am no longer than 2h, light and scattering light during the day to accept the time not less than 6h. After entering the middle of February, as the weather gradually gets warmer, the greenhouse above the maximum temperature can reach 35 ��, then leaked to pay attention to proper temperature, around noon time and reasonable extension of hints to increase ventilation and avoid temperatures above 35 ��. <br /> More articles related to topics： <br /> <br /> <br /> <a href="http://www.feel2.fora.pl/nasz-button,24/buy-ghd-hair-agriculture-product-development-can-d,27194.html#37994" target="_blank" class="postlink">buy ghd hair Agriculture Product development can d</a> <br /> <br /> <a href="http://www.public4you.fora.pl/reading-and-watching,34/abercrombie-outlet-employment-mood-keywords-_2865,21718.html#58188" target="_blank" class="postlink">abercrombie outlet Employment mood Keywords _2865</a> <br /> <br /> <a href="http://www.darknessevolution.fora.pl/general-discussion,5/mbt-shoes-on-sale-the-changing-media-often-a-new,25244.html#33328" target="_blank" class="postlink">mbt shoes on sale The changing media, often a new</a></span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/Avalanche/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
