To cultivate the soil to "three bogeys"
One bogey application of excessive nitrogen fertilizer, resulting in imbalance in nutrient absorption, there "Wang plant."
After the beginning of autumn, as the temperature gradually decreases, the nutrient of ginger stems and leaves will gradually “backflow†into underground tubers, promoting its expansion. If high-nitrogen fertilizers are still applied at this stage, it will inevitably lead to “wang shiâ€. Plant nutrients will be consumed in the growth of stems and leaves, and nutrients accumulated in underground tubers will decrease, leading to a decrease in yield.
Two bogey earth soil wounds, resulting in the spread of soil-borne diseases, spread, dead trees increase.
In recent years, Jiang Nong has used more and more machinery to cultivate soil, and this has, to some extent, aggravated the "damage" of ginger root system. According to the analysis, if ginger is seriously injured, it will inevitably affect the absorption of ginger nutrients and moisture, thus hindering growth. At the same time, due to root wounds, wounds appear, and the ability of the roots to resist disease, can easily lead to the increase of soil-borne diseases, such as bacterial wilt (ginger disease). Combined with the current positive rainy season, the spread of disease is very likely.
So how can we avoid it? One is to use artificial earth as much as possible. If you use mechanical earth, you should also pay attention to the depth of 30 cm ridge height is appropriate. Second, in the case that the soil-cultivation method cannot be changed, it is possible to avoid excessive rooting by adjusting the growth direction of the ginger underground ginger block. That is, when sowing the ginger mother, the ginger mother is consciously perpendicular to the planting line, making the ginger, Sun Jiang is also vertical to the planting line. When the soil is cultivated, the entire ginger block is perpendicular to the planting line. The fleshy roots, lateral roots, and capillary roots caused by soil cultivation extend in a straight line and do not become excessive when cultivated soil. hurt.
Three bogey fertilizer immediately after watering. After topdressing with ginger, it is not possible to water immediately, and it should be watered every other day to facilitate the healing of root wounds of ginger.
