Mulberry frost damage and its response to the occurrence of


Light damage. Such as the Lake Sang Yu 71-1, early in the case of students mulberry varieties of earlier germination occurred when the victim than that of the Night Husang 32 serious. 3.2.2 age,[link widoczny dla zalogowanych], tree vigor,[link widoczny dla zalogowanych], and maturity of the different branches of their cold resistance is also different under normal circumstances, mature and strong branch of Cold Hardiness than immature, adult trees than young trees strong, robust growth vigor than the growth of weak or Cold hardiness of strong growth, excessive, the result too much, and the cold hardiness of tree vigor of aging is relatively weak, the lower trunk of the more serious victims, senior cadres of the dry Sang Sang victims than in the low light. 3.2.3 different growth stages of different cold hardiness of mulberry into the late fall, the plant gradually stop growing, natural leaves,[link widoczny dla zalogowanych], to sleep through the cold acclimation period, the stage of the strongest cold. With the arrival of spring, the temperature gradually increased, gradually lifting exercise, cold hardiness gradually to a minimum. Mulberry ten degrees below zero in winter cold is also dead, several degrees below zero in early spring is enough to frostbite them. 3.3 Mulberry external temperature frost damage occurred in adverse weather conditions,[link widoczny dla zalogowanych], weather conditions 3.3.1 is caused by low-temperature frost damage mulberry direct factors, by the mild winter climate, the spring temperatures rise early, mulberry leaf buds open early germination, shoot the storage metabolism of nutrients for growth and respiration, mulberry root a large number of water, leaves the relative increase in water content within the cell, protoplasm mucus decreased significantly reduce cold hardiness, this time below 0 �� Zai Yu Strong cold air invasion, mulberry vulnerable to frost damage. 3.3.2 Site Condition saying goes, lighter than moist soil drought. 3.3.3 Management position extensive management, partial nitrogen, barren soil, the result too much, too busy growing, cutting injuries too, weak grower, the resistance is poor, by low temperature frost serious harm. Over the late autumn with the leaves, leaving less nutrients in the tree leaves less than normal, significantly increase the damage by frost, whereas less affected. 4 Mulberry Night Cream 4.1 Preventive measures against frost damage observed is predictable weather of spring germination season of mulberry trees, especially in early April, listen to the local meteorological department should pay attention to weather forecasts, while observing the local micro-climate, generally cold front coming in the evening fine no wind, moon and stars bright and clear, about 9 pm the temperature at 8 ��, to the middle of the night down to about 5 ��, so the climate is most likely to occur in the pre-dawn frost. 4.2 with a variety of updates, adaptation and development when necessary to appropriately increase in Mulberry Mulberry Late 2008 a good set of Wei Jiang, the proportion of mulberry varieties in the introduction and promotion to be careful, it is necessary to consider the high yield and quality, but also take into account the resistance, especially the end where late frost, early species of note as far as possible, the species of being older varieties with a reasonable, to prevent a single species of mulberry, rearing of silkworms. If the city rich Changan, new extension of the mulberry planting and breeding Husang 32 71-1, according to the ratio of 3:7 configuration. 4.3 In order to improve rational use of mulberry leaf resistance to freezing capacity, with a leaf can not fall over, particularly in late autumn with the leaves after the mature mulberry branches at the top should be left in the 3 to 4 leaves, leaving young Sang 7 8, At the same time try not to bias the process of fertilization nitrogen, organic fertilizer and trace elements to increase K fertilizer to enhance tree vigor. 4.4 Fumigation frost under the weather forecast, before the coming of the frost, in the mulberry upwind, deepened every 10 meters 30 centimeters in diameter and 90 cm round hole, delegate hay, put the wet grass, at about 2 pm midnight , when the temperature dropped to 3. c or so, ignite firewood fumes, enveloped the entire Mulberry can avoid or mitigate to some extent of frost damage to the mulberry. The role of fume is smoke can inhibit the Mulberry lower heat and cold air to the lower parts of divergent settlement. 4.5 Irrigation water frost on the mulberry, mulberry or irrigation can increase the heat capacity and thermal conductivity of soil, while increasing the air humidity, reducing radiation cooling. Mulberry Night the day before the irrigation, soil temperature and can effectively alleviate the rapid decline in air temperature,[link widoczny dla zalogowanych], the temperature in a low rate of decline. 5 Night remedial measures after the damage has thawed Mulberry 5.1 Drought timely irrigation, use of aerosol spray on mulberry shoots were able to relieve frostbite and reduce the damage degree. Article 5.2 of mulberry cutting has a moderate ability to regenerate, severe frost damage can be moderate pruning of mulberry branches, branches in the lower part is not to promote germination of mulberry bud dormancy and improve germination rate and mild without shear shoot the victims. Additional 5.3 Adding fertilizer to the victims of a quick result Kuwata fertilizer, about 25 kilograms of urea per acre. After germination of mulberry leaves open, in late April to mid-May, every other week with 0.5% urea dilution for two to three times the root outside the Yemianpenfei to increase leaf yield. 5.4 under the mulberry tree species suffer delayed fat level can be adjusted silkworms out of library hours, delayed hair types, to ensure Chuncan harvest.
