Preventing Lodging of Yellow Cabbage in Sheds
The cause of lodging of leeks in greenhouses is mostly the overgrowth of leeks, resulting in thin and slender stems of pseudo-stems, or the hypertrophy and top-heavy leaves of leeks.
In case of this kind of situation, it is necessary to use the vegetable strong stem and promote Huawang No. 3 in time, so that the stem of the amaranth stem is thick, the leaves are thick, the leaves are fresh and the plants are lush. At the same time, it can improve the anti-disaster ability of the growth process of leeks, reduce the amount of pesticides and fertilizers, and reduce pesticide residues.
If the shed is baited, do not cut the leaves of leeks to prevent the cutting leaves from reducing the nutrients accumulated in the leeks and affecting the yield after the shed. Yellow leeks occur, but they cannot be harvested. You can rake down some leeks by hand. You can also use wooden sticks to pick one side of leeks and one side of the leeks and the roots of leeks to make them fully visible and transparent. Every 4-5 days, the leeks are turned to the other side, so that they are fully exposed to light and ventilation, and photosynthetic nutrient film fertilizers are sprayed. By alternately using them, the yellowing and rot of leeks can be avoided and the leeks can be improved. The yield.
