Once garlic is scattered, it means the loss of commodity value, which is devastating to garlic farmers. It means that the upfront cost, capital investment and management investment are all "wasting time" in the end. In order to avoid this situation, we must improve the management of garlic farmers before harvest and avoid some wrong management practices. So, what are the reasons and management methods of garlic loose petals?
1. Unreasonable fertilization For some small plots with poor soil layer, after the young garlic shoots are harvested, moderately topdressing thin fertilizer or spraying urea solution according to the leaves is a reasonable planting management measure to increase the yield.
However, some garlic farmers have a vague understanding of fertilization management at this stage. After the young garlic shoots were harvested, they saw that the leaves turned yellow gradually, so they blindly applied too much base fertilizer. In this way, the garlic cloves that have been established in the garlic position will gradually germinate before harvesting, and finally the conclusion is that garlic will grow twice to form "horsetail garlic".
In the case of horsetail garlic, the stem disk of garlic will rot quickly, which is very easy to cause the petals to loosen. Management suggestion: avoid using too much fertilizer after garlic shoots are harvested, especially avoiding applying base fertilizer at the roots.
Second, blindly watering After the garlic shoots are harvested, if the land is astringent, moderate water injection must be carried out at this time, which can promote the action period of garlic leaves and roots to increase garlic yield. However, if the soil layer is sticky or not too dry, blind watering or even excessive water supply and drainage will lead to long-term water storage in farmland, which will easily lead to accelerated decay of stems and discs that are already in the stage of functional decline, and eventually lead to the phenomenon of petal scattering.
Management suggestion: If the soil layer is sandy or the continuous drought causes serious water shortage, it must be watered once, but it is not necessary to water it when the dry humidity is suitable or wet and sticky. The basic principle is that we would rather have moderate drought than blindly irrigate the flood.
Third, the improper harvesting time of garlic bolts can reduce the competition for nutrients under the condition of constant garlic yield, which has a very obvious effect on improving garlic yield and quality. However, the early harvest of garlic moss will not only endanger the yield and economic benefits of garlic bolts, but also inevitably lead to unsafe behavior on garlic pseudostems, thus accelerating the decline of leaf function.
On the one hand, it is not conducive to the increase of garlic yield, and the false hollow stems produced by harvesting garlic moss are also easy to cause dew or precipitation to seep downward, which may expand the possibility of stem rot. If there are some fungal diseases and insect pests, the probability of stem rot will be more significantly improved.
Similarly, if garlic moss is harvested too late, on the one hand, the commercialization of garlic moss will be reduced due to the high degree of liver fibrosis, on the other hand, the output of garlic will continue to be reduced due to the competition for nutrients. Precipitation will gradually increase in the later period, and because garlic moss absorbs too much nutrients, the nutrient supply of underground organs is insufficient and the resistance is poor, it is easy to increase the proportion of scattered petals. Management suggestion: firmly grasp the harvesting time of garlic bolts, generally, the garlic packets are gradually bent, and the most suitable harvesting time is when the garlic packets turn white.
Fourth, the garlic harvest time is uncertain. If you get up early, although it is not easy to spread the petals, the yield will be slightly lower, which will endanger the planting efficiency. If the harvest is late, the probability of loose petals will be greatly improved. If it rains before and after harvest, the probability of loose petals will greatly increase. Therefore, combining with the weather conditions, firmly grasping the futures trading time is a core to ensure the safe cultivation of garlic.
Management suggestion: Two-thirds of garlic cloves have begun to turn yellow, and the false stems are soft but still healthy. It should also be emphasized that the harvest time should be flexible, especially pay attention to the weather forecast, if it is suitable for the harvest time. In case of continuous rain, it is necessary to harvest early to avoid excessive adhesion of soil layer after continuous rain, which will lead to difficulties in harvesting and increase the risk of loose petals.
In addition to the above points, the main reason for loose petals when humidity is high, we must master the correct drying method after garlic harvest, otherwise it will also cause loose petals after garlic harvest. The drying time after harvest should be timely, otherwise the high water content lasts for a long time, and the young garlic shoots are easy to rot.
