What to do when ginger grows poorly? Properly controlling nutrition is key

Growing ginger

    When ginger crops grow well in their above-ground organs but poorly in their underground rhizomes, this is mainly because vegetative growth is too strong and has suppressed reproductive growth. As a ginger crop, ginger needs its vegetative growth to be properly controlled in order to promote reproductive growth. The specific measures are as follows:

    1. Scientific fertilization. Because ginger crops have a long growing period and the harvest is mainly the tubers, the base fertilizer should be applied generously, mainly with organic fertilizer that has a long residual effect, combined with an appropriate and moderate amount of chemical fertilizer. Before the tubers expand, apply Yaocai Gendaling in time, which can promote the transport of leaf photosynthetic products (nutrients) to the root system, improve the nutrient conversion rate and the soil-loosening capacity, make the rhizomes expand rapidly, and greatly increase the content of active substances.

⟧     2. Around the Beginning of Autumn, during the growth transition period of ginger crops (the transition period refers to the shift of ginger crops from vegetative growth, dominated by sprouting branches and growing leaves, to reproductive growth, dominated by tuber development and expansion), apply one heavy fertilizer. The structure of this fertilization is a combination of organic fertilizer and quick-acting chemical fertilizer. Use the residual effect of the organic fertilizer to maintain the nutrient requirements for the growth of above-ground organs and prevent premature senescence of stems and leaves, so that the organic matter produced by the leaves is maximized as much as possible and transported downward to meet the needs of tuber development. Use the effect of the quick-acting fertilizer to promptly meet the needs of tuber expansion. The amount of this fertilization can be appropriately increased or decreased according to the growth of the ginger plants. If the vegetative growth of the ginger plants is relatively vigorous, then apply less or none, and spray Chuhuawang No. 3 to convert the plant's vegetative growth into reproductive nutrition and suppress excessive growth of the main shoots.

    3. Reasonable water control. Pay attention to the water supply during the tuber expansion period to facilitate the rapid formation of underground organs. About 4-5 days before harvest, water supply should be stopped.
