First, the main reasons for not germinating: 1, seed Valley water absorption time is short, lack of water; 2, the number of seeds is small, the preheat temperature is not enough, the initial temperature is too low when people piled up to germination; 3, more water insulation effect is poor, Valley The temperature in the heap does not reach the required temperature for germination and cannot be broken. When the seedlings do not germinate, they should analyze the causes and treat them differently. If the initial temperature of the pile is low and the seed moisture is insufficient, then the temperature can be adjusted to about 60°C, warming and moistening, and then germination; if the water temperature is too low, the temperature of the grain pile is low, and the soil can be dried on a sunny day. Re-warm germination; rainy days can be used a small amount of hot water seed dressing, coupled with the appropriate amount of dry honeycomb ash dehumidify air, re-germination. Pay attention to strengthen the insulation when germinating.
Second, after the sprouting of the seed-burdened valley, when the temperature of the stack exceeds 40°C and the duration is long, the phenomenon of sprouting is prone to occur. The people are commonly called "burning barrels." Burned buds have yellow rust or buds on the buds of light buds. The buds and apical buds of burned shoots are dead and accompanied by a taste of the wine. This is because the temperature of the stack is too high and the air is poor. Breathing, caused by alcohol accumulation poisoning. The key to prevent burning buds is to pay attention to the change of temperature after breaking the chest. When the temperature is too high, the heat is disintegrated in time.
Third, the main symptoms of skeletal escarpment is that the husk is sticky and snaking, and when it is severe, it becomes a group and cannot be automatically dispersed. The main reasons for this are the excessive moisture before the dew-whitening of the seeds, the strong anaerobic respiration, the spillage of sugar from the seeds, and the organic acid produced by the fermentation, which allows the microorganisms to multiply rapidly on the surface of the chaff and cause the chaff to become sticky. , Produce sour taste and liquor, commonly known as "sliding shell." Seeds with low germination temperature, long exposure time, and poor viability are most susceptible to slippery shells. Selecting seed, controlling dew-white moisture and maintaining a sufficient temperature (generally about 35°C) is the main method of preventing slippery shells.
Fourth, root buds sprouting budding process often occur in the length of root buds phenomenon, sometimes buds without roots or roots are very short, or the root is very long and very short buds. The main cause of root bud malformation is caused by improper control of temperature and humidity. In the valley where the moisture is uneven, where there is much moisture and where there is less oxygen, the phenomenon of short shoot root length due to "wet long shoots" occurs. In areas where there is little water and oxygen, there are short root shoots due to "long dry roots". The valley temperature is uneven, generally the center of the heap is high in temperature and oxygen is low. The phenomenon of “warm long rooting†occurs. The young root grows slowly; the surrounding and low surface temperature of the stack, oxygen is sufficient, and the young root grows slowly, but the coleoptile If the elongation is relatively small due to the influence of temperature, the phenomenon of "cold shoots" appears. Therefore, before and after breaking the chest, it is necessary to fully coordinate the conditions of moisture, temperature and oxygen, and evenly plant the seed to prevent the length of root buds from being uneven.
